Using ALT/OPT + drag to clone does not transfer the bindings (or leaves the duplicates in place of the old one , which are also not bound).
Signed-off-by: Mark Tolmacs <mark@lazycat.hu>
The LinearElementEditor.movePoints() function incorrectly calculates the offset for local linear element points when multiple targetPoints are provided, one of those target points is index === 0 AND the other points are moved in the negative direction, and ending up with negative local coordinates.

* fix `dockable` prop of defaultSidebar
* remove extra `typescript` dep
* remove `defaultTab` prop
in favor of explicit `tab` value in `<Sidebar.Trigger/>` and `toggleSidebar()`, to reduce API surface area and solve inconsistency of `appState.openSidebar.tab` not reflecting actual UI value if `defaultTab` was supported (without additional syncing logic which feels like the wrong solution).

Earlier we were using `renderFooter` prop to render custom footer which was removed in [#5970](https://github.com/excalidraw/excalidraw/pull/5970). Now you can pass a `Footer` component instead to render the custom UI for footer.
You will need to import the `Footer` component from the package and wrap your component with the Footer component. The `Footer` should a valid React Node.

Here is a [complete list](https://github.com/excalidraw/excalidraw/blob/master/src/components/mainMenu/DefaultItems.tsx) of the default items.
Here is a [complete list](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/components/main-menu/DefaultItems.tsx) of the default items.
The editor comes with a default sidebar on the right in LTR (Left to Right) mode which contains the library. You can also add your own custom sidebar(s) by rendering this component as a child of `<Excalidraw>`.
## Props
| Prop | Type | Required | Description |
| --- | --- | --- | --- |
| `name` | `string` | Yes | Sidebar name that uniquely identifies it. |
| `children` | `React.ReactNode` | Yes | Content you want to render inside the sidebar. |
| `onStateChange` | `(state: AppState["openSidebar"]) => void` | No | Invoked on open/close or tab change. No need to act on this event, as the editor manages the sidebar open state on its own. |
| `onDock` | `(docked: boolean) => void` | No | Invoked when the user toggles the `dock` button. Passed the current docked state. |
| `docked` | `boolean` | No | Indicates whether the sidebar is `docked`. By default, the sidebar is `undocked`. If passed, the docking becomes controlled. |
| `className` | `string` | No | |
| `style` | `React.CSSProperties` | No | |
At minimum, each sidebar needs to have a unique `name` prop, and render some content inside it, which can be either composed from the exported sidebar sub-components, or custom elements.
Unless `docked={true}` is passed, the sidebar will close when the user clicks outside of it. It can also be closed using the close button in the header, if you render the `<Sidebar.Header>` component.
Further, if the sidebader doesn't comfortably fit in the editor, it won't be dockable. To decide the breakpoint for docking you can use [UIOptions.dockedSidebarBreakpoint](/docs/@excalidraw/excalidraw/api/props/ui-options#dockedsidebarbreakpoint).
To make your sidebar user-dockable, you need to supply `props.docked` (current docked state) alongside `props.onDock` callback (to listen for and handle docked state changes). The component doesn't track local state for the `docked` prop, so you need to manage it yourself.
## Sidebar.Header
| Prop | Type | Required | Description |
| --- | --- | --- | --- |
| `children` | `React.ReactNode` | No | Content you want to render inside the sidebar header next to the `close` / `dock` buttons. |
| `className` | `string` | No | |
Renders a sidebar header which contains a close button, and a dock button (when applicable). You can also render custom content in addition.
Can be nested inside specific tabs, or rendered as direct child of `<Sidebar>` for the whole sidebar component.
| `children` | `React.ReactNode` | No | Tab content. |
Content of a given sidebar tab. It must be rendered inside `<Sidebar.Tabs>`.
## Sidebar.TabTriggers
| Prop | Type | Required | Description |
| --- | --- | --- | --- |
| `children` | `React.ReactNode` | No | Container for individual tab triggers. |
Container component for tab trigger buttons to switch between tabs.
## Sidebar.TabTrigger
| Prop | Type | Required | Description |

[`MIME_TYPES`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/constants.ts#L101) contains all the mime types supported by `Excalidraw`.
We support a simplified API to make it easier to generate Excalidraw elements programmatically. This API is in beta and subject to change before stable. You can check the [PR](https://github.com/excalidraw/excalidraw/pull/6546) for more details.
For this purpose we introduced a new type [`ExcalidrawElementSkeleton`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133). This is the simplified version of [`ExcalidrawElement`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/element/types.ts#L134) type with the minimum possible attributes so that creating elements programmatically is much easier (especially for cases like binding arrows or creating text containers).
The [`ExcalidrawElementSkeleton`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133) can be converted to fully qualified Excalidraw elements by using [`convertToExcalidrawElements`](/docs/@excalidraw/excalidraw/api/excalidraw-element-skeleton#converttoexcalidrawelements).
## convertToExcalidrawElements
**_Signature_**
```ts
convertToExcalidrawElements(
elements: ExcalidrawElementSkeleton,
opts?: { regenerateIds: boolean }
): ExcalidrawElement[]
```
| Name | Type | Default | Description |
| --- | --- | --- | --- |
| `elements` | [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L137) | | The Excalidraw element Skeleton which needs to be converted to Excalidraw elements. |
| `opts` | `{ regenerateIds: boolean }` | ` {regenerateIds: true}` | By default `id` will be regenerated for all the elements irrespective of whether you pass the `id` so if you don't want the ids to regenerated, you can set this attribute to `false`. |
**_How to use_**
```js
import { convertToExcalidrawElements } from "@excalidraw/excalidraw";
```
This function converts the Excalidraw Element Skeleton to excalidraw elements which could be then rendered on the canvas. Hence calling this function is necessary before passing it to APIs like [`initialData`](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/api/props/initialdata), [`updateScene`](https://docs.excalidraw.com/docs/@excalidraw/excalidraw/api/props/excalidraw-api#updatescene) if you are using the Skeleton API
## Supported Features
### Rectangle, Ellipse, and Diamond
To create these shapes you need to pass its `type` and `x` and `y` coordinates for position. The rest of the attributes are optional\_.
For the Skeleton API to work, `convertToExcalidrawElements` needs to be called before passing it to Excalidraw Component via initialData, updateScene or any such API.
You can pass additional [`properties`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/element/types.ts#L27) as well to decorate the shapes.
:::info
You can copy the below test examples and replace the elements in the live editor above to test it out.
In addition to `type`, `x` and `y` properties, [`label`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L124C7-L130C59) property is required for text containers. The `text` property in `label` is required, rest of the attributes are optional.
If you don't provide the dimensions of container, we calculate it based of the label dimensions.
To bind arrow to a shape you need to specify its [`start`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L86) and [`end`](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L54) properties. You need to pass either `type` or `id` property in `start` and `end` properties, rest of the attributes are optional
```js
convertToExcalidrawElements([
{
type: "arrow",
x: 255,
y: 239,
label: {
text: "HELLO WORLD!!",
},
start: {
type: "rectangle",
},
end: {
type: "ellipse",
},
},
]);
```
When position for `start` and `end ` properties are not specified, we compute it according to arrow position.

## readyPromise
:::info The `Ref` support has been removed in v0.17.0 so if you are using refs, please update the integration to use the `excalidrawAPI`.
Additionally `ready` and `readyPromise` from the API have been discontinued. These APIs were found to be superfluous, and as part of the effort to streamline the APIs and maintain simplicity, they were removed in version v0.17.0.
Since plain object is passed as a `ref`, the `readyPromise` is resolved as soon as the component is mounted. Most of the time you will not need this unless you have a specific use case where you can't pass the `ref` in the react way and want to do some action on the host when this promise resolves.

Beyond attributes that Excalidraw elements already support, you can store `custom` data on each `element` in a `customData` object. The type of the attribute is [`Record<string, any>`](https://github.com/excalidraw/excalidraw/blob/master/src/element/types.ts#L66) and is optional.

You can use this to add any extra information you need to keep track of.
You can add `customData` to elements when passing them as [`initialData`](/docs/@excalidraw/excalidraw/api/props/initialdata), or using [`updateScene`](/docs/@excalidraw/excalidraw/api/props/ref#updatescene) / [`updateLibrary`](/docs/@excalidraw/excalidraw/api/props/ref#updatelibrary) afterwards.

You can render `custom sidebar` using this prop. This sidebar is the same that the library menu sidebar is using, and can be used for any purposes your app needs.
Allows you to replace the renderer for embeddable elements (which renders `<iframe>` elements).
You need to import the `Sidebar` component from `excalidraw` package and pass your content as its `children`. The function `renderSidebar` should return the `Sidebar` instance.
### Sidebar
The `<Sidebar>` component takes these props (all are optional except `children`):
| Prop | Type | Description |

| `children` | `React.ReactNode` | Content you want to render inside the `sidebar`. |
| `onClose` | `function` | Invoked when the component is closed (by user, or the editor). No need to act on this event, as the editor manages the sidebar open state on its own. |
| `onDock` | `function` | Invoked when the user toggles the `dock` button. The callback recieves a `boolean` parameter `isDocked` which indicates whether the sidebar is `docked` |
| `docked` | `boolean` | Indicates whether the sidebar is`docked`. By default, the sidebar is `undocked`. If passed, the docking becomes controlled, and you are responsible for updating the `docked` state by listening on `onDock` callback. To decide the breakpoint for docking you can use [UIOptions.dockedSidebarBreakpoint](/docs/@excalidraw/excalidraw/api/props/ui-options#dockedsidebarbreakpoint) for more info on docking. |
| `dockable` | `boolean` | Indicates whether to show the `dock` button so that user can `dock` the sidebar. If `false`, you can still dock programmatically by passing `docked` as `true`. |
The sidebar will always include a header with `close / dock` buttons (when applicable).
You can also add custom content to the header, by rendering `<Sidebar.Header>` as a child of the `<Sidebar>` component. Note that the custom header will still include the default buttons.
### Sidebar.Header
| name | type | description |
| --- | --- | --- |
| children | `React.ReactNode` | Content you want to render inside the sidebar header as a sibling of `close` / `dock` buttons. |
To control the visibility of the sidebar you can use [`toggleMenu("customSidebar")`](/docs/@excalidraw/excalidraw/api/props/ref#togglemenu) api available via `ref`.

To filter `elements` that are inside, overlap, or contain the `bounds` rectangle.
The bounds check is approximate and does not precisely follow the element's shape. You can also supply `errorMargin` which effectively makes the `bounds` larger by that amount.
This API has 3 `type`s of operation: `overlap`, `contain`, and `inside`:
- `overlap` - filters elements that are overlapping or inside bounds.
- `contain` - filters elements that are inside bounds or bounds inside elements.
- `inside` - filters elements that are inside bounds.

### Turning off Aggressive Anti-Fingerprinting in Brave browser
When *Aggressive Anti-Fingerprinting* is turned on, the `measureText` API breaks which in turn breaks the Text Elements in your drawings. Here is more [info](https://github.com/excalidraw/excalidraw/pull/6336) on the same.
We strongly recommend turning it off. You can follow the steps below on how to do so.
1. Open [excalidraw.com](https://excalidraw.com) in Brave and click on the **Shield** button

<div style={{width:'30rem'}}>
2. Once opened, look for **Aggressively Block Fingerprinting**
4. Thats all. All text elements should be fixed now 🎉

If disabling this setting doesn't fix the display of text elements, please consider opening an [issue](https://github.com/excalidraw/excalidraw/issues/new) on our GitHub, or message us on [Discord](https://discord.gg/UexuTaE).

Excalidraw depends on assets such as localization files (if you opt to use them), fonts, and others.
By default, Excalidraw will try to download all the used fonts from the [CDN](https://esm.run/@excalidraw/excalidraw/dist/prod).
By default these assets are loaded from a public CDN [`https://unpkg.com/@excalidraw/excalidraw/dist/`](https://unpkg.com/@excalidraw/excalidraw/dist), so you don't need to do anything on your end.
However, if you want to host these files yourself, you can find them in your `node_modules/@excalidraw/excalidraw/dist` directory, in folders `excalidraw-assets` (for production) and `excalidraw-assets-dev` (for development).
Copy these folders to your static assets directory, and add a `window.EXCALIDRAW_ASSET_PATH` variable in your `index.html` or `index.js` entry file pointing to your public assets path (relative). For example, if you serve your assets from the root of your hostname, you would do:
For self-hosting purposes, you'll have to copy the content of the folder `node_modules/@excalidraw/excalidraw/dist/prod/fonts` to the path where your assets should be served from (i.e. `public/` directory in your project). In that case, you should also set `window.EXCALIDRAW_ASSET_PATH` to the very same path, i.e. `/` in case it's in the root:
```js
window.EXCALIDRAW_ASSET_PATH = "/";
```
or, if you serve your assets from the root of your CDN, you would do:
{ `window["EXCALIDRAW_ASSET_PATH"] = location.origin;` } // or use just "/"!

### Rendering Excalidraw only on client
### Next.js
Since _Excalidraw_ doesn't support server side rendering, you should render the component once the host is `mounted`.
Since Excalidraw doesn't support `server side rendering` so it should be rendered only on `client`. The way to achieve this in next.js is using `next.js dynamic import`.
If you want to only import `Excalidraw` component you can do :point_down:
The `types` are available at `@excalidraw/excalidraw/types`, you can view [example for typescript](https://codesandbox.io/s/excalidraw-types-9h2dm)
However the above component only works for named component exports. If you want to import some util / constant or something else apart from Excalidraw, then this approach will not work. Instead you can write a wrapper over Excalidraw and import the wrapper dynamically.
If you are using `pages router` then importing the wrapper dynamically would work, where as if you are using `app router` then you will have to also add `useClient` directive on top of the file in addition to dynamically importing the wrapper as shown :point_down:
{/* Link should be updated to point to the latest! */}
Here is a [source code](https://github.com/excalidraw/excalidraw/tree/master/examples/with-nextjs) for the example with app and pages router. You you can try it out [here](https://excalidraw-package-example-with-nextjs.vercel.app/).
The `types` are available at `@excalidraw/excalidraw/types`, check [CodeSandbox](https://codesandbox.io/p/sandbox/github/excalidraw/excalidraw/tree/master/examples/with-script-in-browser) example for details.
### Preact
Since we support `umd` build ships with `react/jsx-runtime` and `react-dom/client` inlined with the package. This conflicts with `Preact` and hence the build doesn't work directly with `Preact`.
However we have shipped a separate build for `Preact` so if you are using `Preact` you need to set `process.env.IS_PREACT` to `true` to use the `Preact` build.
Once the above `env` variable is set, you will be able to use the package in `Preact` as well.

At the moment the mermaid-to-excalidraw works in two steps. First, you call `parseMermaidToExcalidraw(mermaidSyntax)` on the mermaid diagram definition string, which resolves with elements in a skeleton format — a simplified excalidraw JSON format (docs coming soon). You then pass them to `convertToExcalidrawElements(elements)` to get the fully qualified excalidraw elements you can render in the editor.
The need for these two steps is due to the [@excalidraw/excalidraw](/docs/@excalidraw/excalidraw/installation) being a **UMD** build so we currently cannot import the `convertToExcalidrawElements()` util alone, until we support a tree-shakeable **ESM** build.
## parseMermaidToExcalidraw
This API receives the mermaid syntax as the input, and resolves to skeleton Excalidraw elements. You will need to call `convertToExcalidraw` API to convert them to fully qualified elements that you can render in Excalidraw.
** Example **
```ts
import { parseMermaidToExcalidraw } from "@excalidraw/mermaid-to-excalidraw";
import { convertToExcalidrawElements} from "@excalidraw/excalidraw"
Currently only [flowcharts](https://mermaid.js.org/syntax/flowchart.html) are supported. Oother diagram types will be rendered as an image in Excalidraw.
### Flowchart
#### Excalidraw Regular Shapes
**Rectangles**, **Circle**, **Diamond**, and **Arrows** are fully supported in Excalidraw
**Subroutine**, **Cylindrical**, **Asymmetric**, **Hexagon**, **Parallelogram**, **Trapezoid** are not supported in Excalidraw hence they fallback to the closest shape **Rectangle**
```
flowchart LR
id1[[Subroutine fallback to Rectangle]]
id2[(Cylindrical fallback to Rectangle)]
id3>Asymmetric fallback to Rectangle]
id4{{Hexagon fallback to Rectangle}}
id5[/Parallelogram fallback to Rectangle /]
id6[/Trapezoid fallback to Rectangle\]
```
The above shapes are not supported in Excalidraw hence they fallback to Rectangle
Since we don't support wysiwyg text editor yet, hence [Markdown Strings](https://mermaid.js.org/syntax/flowchart.html#markdown-strings) will fallback to regular text.
The [FontAwesome](https://mermaid.js.org/syntax/flowchart.html#basic-support-for-fontawesome) icons aren't support so they won't be rendered in Excalidraw
Currently only [flowcharts](https://mermaid.js.org/syntax/flowchart.html) are supported. All other diagram types will be rendered as an image in Excalidraw.
* [How Parser Works under the hood](/docs/@excalidraw/mermaid-to-excalidraw/codebase/parser) - If you are interested in understanding and deep diving into inner workings of the Parser, then make sure to checkout this section.
* [Adding a new diagram type](/docs/@excalidraw/mermaid-to-excalidraw/codebase/new-diagram-type) - If you want to help us make the mermaid to Excalidraw Parser more powerful, you will find all information in this section to do so.
To add a new diagram type to the parser you can follow the below steps :point_down:
All the code for the parser resides in [`src`](https://github.com/excalidraw/mermaid-to-excalidraw/tree/master/src) folder and for playground resides in [`playground`](https://github.com/excalidraw/mermaid-to-excalidraw/tree/master/playground) folder.
lets run the playground server in local :point_down:
```bash
yarn start
```
This will start the playground server in port `1234` and open it in browser so you start playing with the playground.
## Update Supported Diagram Types
First step is to add the new diagram type in [`SUPPORTED_DIAGRAM_TYPES`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/constants.ts#L2).
Once this is done the new diagram type won't be rendered as an image but start throwing error since we don't support parsing the data yet.
## Writing the Diagram Parser
Once the diagram type is added in previous step. Next step is to write the parser to parse the mermaid diagram.
For this create a file named `{{diagramType}}.ts` in [`src/parser`](https://github.com/excalidraw/mermaid-to-excalidraw/tree/master/src/parser) and write a function `parseMermaid{{diagramType}}Diagram` similar to how we [`parseMermaidFlowChartDiagram`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parser/flowchart.ts#L256) for parsing flowchart diagram.
The main aim of the parser is :point_down:
1. Determine how elements are connected in the diagram and thus finding arrow and text bindings.
For this you might have to dig in to the parser `diagram.parser.yy` and which attributes to parse for the new diagram.
2. Determine the position and dimensions of each element, for this would be using the `svg`
Once the parser is ready, lets start using it.
Add the diagram type in switch case in [`parseMermaid`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parseMermaid.ts#L97) and call the parser for the same.
## Writing the Excalidraw Skeleton Convertor
With the completion of previous step, we have all the data, now we need to transform it so to [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133) format.
Similar to [`FlowChartToExcalidrawSkeletonConverter`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/converter/types/flowchart.ts#L24), you have to write the `{{diagramType}}ToExcalidrawSkeletonConverter` which parses the data received in previous step and returns the [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133).
Thats it, you have added the new diagram type 🥳, now lets test it out!
## Updating the Playground
1. Create a file named `{{diagramType}}.ts` in [`playround/testcases/`](https://github.com/excalidraw/mermaid-to-excalidraw/tree/master/playground/testcases). For reference you can check [`flowchart.ts`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/playground/testcases/flowchart.ts).
2. Incase the new diagram type added is present in [`unsupported.ts`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/playground/testcases/unsupported.ts) then remove it from there.
3. Verify if the test cases are running fine in playground.
As mentioned in the previous section, we use [getDiagramFromText](https://github.com/mermaid-js/mermaid/blob/00d06c7282a701849793680c1e97da1cfdfcce62/packages/mermaid/src/Diagram.ts#L80) to parse the full defination and get the [Diagram](https://github.com/mermaid-js/mermaid/blob/00d06c7282a701849793680c1e97da1cfdfcce62/packages/mermaid/src/Diagram.ts#L15) json from it.
In this section we will be diving into how the [flowchart parser](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parser/flowchart.ts#L256) works behind the scenes.
We use `diagram.parser.yy` attribute to parse the data. If you want to know more about how the `diagram.parse.yy` attribute looks like, you can check it [here](https://github.com/mermaid-js/mermaid/blob/00d06c7282a701849793680c1e97da1cfdfcce62/packages/mermaid/src/diagrams/flowchart/flowDb.js#L768), however for scope of flowchart we are using **3** APIs from this parser to compute `vertices`, `edges` and `clusters` as we need these data to transform to [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133C13-L133C38).
For computing `vertices` and `edge`s lets consider the below svg generated by mermaid
We use `getVertices` API from `diagram.parse.yy` to get the vertices for a given flowchart.
Considering the same example this is the response from the API
```js
{
"start": {
"id": "start",
"labelType": "text",
"domId": "flowchart-start-1414",
"styles": [],
"classes": [],
"text": "start",
"props": {}
},
"stop": {
"id": "stop",
"labelType": "text",
"domId": "flowchart-stop-1415",
"styles": [],
"classes": [],
"text": "stop",
"props": {}
}
}
```
The dimensions and position is missing in this response and we need that to transform to [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133C13-L133C38), for this we have our own parser [`parseVertex`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parseMermaid.ts#L178) which takes the above response and uses the `svg` together to compute position, dimensions and cleans up the response.
The final output from `parseVertex` looks like :point_down:
```js
{
"start": {
"id": "start",
"labelType": "text",
"text": "start",
"x": 0,
"y": 0,
"width": 67.796875,
"height": 44,
"containerStyle": {},
"labelStyle": {}
},
"stop": {
"id": "stop",
"labelType": "text",
"text": "stop",
"x": 117.796875,
"y": 0,
"width": 62.3828125,
"height": 44,
"containerStyle": {},
"labelStyle": {}
}
}
```
## Computing the edges
The lines and arrows are considered as `edges` in mermaid as shown in the above diagram.
We use `getEdges` API from `diagram.parse.yy` to get the edges for a given flowchart.
Considering the same example this is the response from the API
```js
[
{
"start": "start",
"end": "stop",
"type": "arrow_point",
"text": "",
"labelType": "text",
"stroke": "normal",
"length": 1
}
]
```
Similarly here the dimensions and position is missing and we compute that from the svg. The [`parseEdge`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parseMermaid.ts#L245) takes the above response along with `svg` and computes the position, dimensions and cleans up the response.
The final output from `parseEdge` looks like :point_down:
```js
[
{
"start": "start",
"end": "stop",
"type": "arrow_point",
"text": "",
"labelType": "text",
"stroke": "normal",
"startX": 67.797,
"startY": 22,
"endX": 117.797,
"endY": 22,
"reflectionPoints": [
{
"x": 67.797,
"y": 22
},
{
"x": 117.797,
"y": 22
}
]
}
]
```
## Computing the Subgraphs
`Subgraphs` is collection of elements grouped together. The Subgraphs map to `grouping` elements in Excalidraw.
We use `getSubgraphs` API to get the subgraph data for a given flowchart.
Considering the same example this is the response from the API
```js
[
{
"id": "one",
"nodes": [
"flowchart-a2-1399",
"flowchart-a1-1400"
],
"title": "one",
"classes": [],
"labelType": "text"
}
]
```
For position and dimensions we use the svg to compute. The [`parseSubgraph`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parseMermaid.ts#L139) takes the above response along with `svg` and computes the position, dimensions and cleans up the response.
[This](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/index.ts) is the entry point of the library.
`parseMermaidToExcalidraw` function is the only function exposed which receives mermaid syntax as the input, parses the mermaid syntax and resolves to Excalidraw Skeleton.
Lets look at the high level overview at how the parse works :point_down:
Lets dive deeper into individual section now to understand better.
## Parsing Mermaid diagram
One of the dependencies of the library is [`mermaid`](https://www.npmjs.com/package/mermaid) library.
We need the mermaid diagram in some extractable format so we can parse it to Excalidraw Elements.
Parsing is broken into two steps
1. [`Rendering Mermaid to Svg`](/docs/@excalidraw/mermaid-to-excalidraw/codebase/parser#rendering-mermaid-to-svg) - This helps in determining the position and dimensions of each element in the diagram
2. [`Parsing the mermaid syntax`](/docs/@excalidraw/mermaid-to-excalidraw/codebase/parser#parsing-the-mermaid-syntax) - We also need to know how elements are connected which isn't possible with svg alone hence we also parse the mermaid syntax which helps in determining the connections and bindings between elements in the diagram.
The [`mermaid`](https://www.npmjs.com/package/mermaid) library provides the API `mermaid.render` API which gives the output of the diagram in `svg`.
If the diagram isn't supported, this svg is converted to `dataURL` and can be rendered as an image in Excalidraw.
### Parsing the mermaid syntax
For this we first need to process the options along with mermaid defination for diagram provided by the user.
[`processMermaidTextWithOptions`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parseMermaid.ts#L13) takes the mermaid defination and options and returns the full defination including the mermaid [directives ](https://mermaid.js.org/config/directives.html).
Next we use mermaid api [getDiagramFromText](https://github.com/mermaid-js/mermaid/blob/00d06c7282a701849793680c1e97da1cfdfcce62/packages/mermaid/src/Diagram.ts#L80) to parse the full defination and get the [Diagram](https://github.com/mermaid-js/mermaid/blob/00d06c7282a701849793680c1e97da1cfdfcce62/packages/mermaid/src/Diagram.ts#L15) json from it.
Next we write our own parser to parse this diagram.
### Parsing the Diagram
For each diagram type, we need a parser as the result of every diagram would differ and dependinng on the data we have to write the parser. Since currently we support flowchart, so here is the [`parseMermaidFlowChartDiagram`](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/parser/flowchart.ts#L256) to parse the flowchart diagram.
If you want to understand how flowchart parser works, you can navigate to [Flowchart Parser](http://localhost:3003/docs/@excalidraw/mermaid-to-excalidraw/codebase/parser/flowchart).
## Converting to ExcalidrawElementSkeleton
Now we have all the data, we just need to transform it to [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133C13-L133C38) API so it can be rendered in Excalidraw.
For this we have `converters` which takes the parsed mermaid data and gives back the Excalidraw Skeleton.
For Unsupported types, we have already mentioned above that we convert it to `dataURL` and return the ExcalidrawImageSkeleton.
For supported types, currently only flowchart, we have [flowchartConverter](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/src/converter/types/flowchart.ts#L24) which parses the data and converts to [ExcalidrawElementSkeleton](https://github.com/excalidraw/excalidraw/blob/master/packages/excalidraw/data/transform.ts#L133C13-L133C38).
This will start the playground server in port `1234` and you start playing with the playground.
## Creating a test release
We will soon simplify creating release via commenting on GitHub PR similar till then you can create a release by following the below steps
1. Create the build
```bash
yarn build
```
This will create the dist folder which we need to publish next.
2. Publish the library
Update the package name and version in [package.json](https://github.com/excalidraw/mermaid-to-excalidraw/blob/master/package.json) and run the below command to publish it
```bash
yarn publish
```
And thats all your test release is successfully created 🎉
`@excalidraw/mermaid-to-excalidraw` is published to npm. This library is used in [excalidraw](https://excalidraw.com) to transform mermaid syntax to Excalidraw diagrams.
Using `npm`
```bash
npm install @excalidraw/mermaid-to-excalidraw
```
Using `yarn`
```bash
yarn add @excalidraw/mermaid-to-excalidraw
```
## Usage
Once the library is installed, its ready to use.
```js
import { parseMermaidToExcalidraw } from "@excalidraw/mermaid-to-excalidraw";
import { convertToExcalidrawElements} from "@excalidraw/excalidraw"
Frames should be ordered where frame children come first, followed by the frame element itself:
```
[
other_element,
frame1_child1,
frame1_child2,
frame1,
other_element,
frame2_child1,
frame2_child2,
frame2,
other_element,
...
]
```
If not ordered correctly, the editor will still function, but the elements may not be rendered and clipped correctly. Further, the renderer relies on this ordering for performance optimizations.
