|
|
-```tsx
|
|
40

-### `useFileSystem`
|

|
|
-
|
|
131
|
|
-You can use the `useFileSystem` hook to get prepared callbacks for `onNewProject`, `onOpenProject`, `onSaveProject`, and `onSaveProjectAs`. These callbacks allow a user to save files via the [FileSystem](https://developer.mozilla.org/en-US/docs/Web/API/FileSystem) API.

-import { TLDraw, useFileSystem } from '@tldraw/tldraw'
|
|
135
|
|
-
|
|
136
|
|
-function App() {
|
|
137
|
|
- const fileSystemEvents = useFileSystem()

|
-### `TLDrawDocument`
|
|
144
|
|
-
|
|
145
|
|
-You can initialize or control the `<TLDraw>` component via its `document` property. A `TLDrawDocument` is an object with three properties:
|
|
146
|
|
-
|
|
147
|
|
-- `id` - A unique ID for this document
|
|
148
|
|
-- `pages` - A table of `TLDrawPage` objects
|
|
149
|
|
-- `pageStates` - A table of `TLPageState` objects
|
|
150
|
|
-- `version` - The document's version, used internally for migrations.
|
|
151
|
|
-
|
|
152
|
|
-```ts
|
|

|
|
182
|
|
-
|
|
183
|
|
-**Tip:** TLDraw is built on [@tldraw/core](https://github.com/tldraw/core). The pages and pageStates in TLDraw are objects containing `TLPage` and `TLPageState` objects from the core library. For more about these types, check out the [@tldraw/core](https://github.com/tldraw/core) documentation.
|
|
184
|
|
-
|
|
185
|
|
-**Important:** In the `pages` object, each `TLPage` object must be keyed under its `id` property. Likewise, each `TLPageState` object must be keyed under its `id`. In addition, each `TLPageState` object must have an `id` that matches its corresponding page.
|
|
186

187
|
|
-### Shapes

|
188
|
|
-
|
|
189
|
|
-Your `TLPage` objects may include shapes: objects that fit one of the `TLDrawShape` interfaces listed below. All `TLDrawShapes` extends a common interface:

-A binding is a connection **from** one shape and **to** another shape. At the moment, only arrows may be bound "from". Most shapes may be bound "to", except other `ArrowShape` and `DrawShape`s.

-### `TLDrawState` API
|
|
282
|
|
-
|
|
283
|
|
-You can change the `TLDraw` component's state through an imperative API called `TLDrawState`. To access this API, use the `onMount` callback, or any of the component's callback props, like `onPersist`.
|
|
284
|
|
-
|
|
285
|
|
-```tsx
|
|
286
|
|
-import { TLDraw, TLDrawState } from '@tldraw/tldraw'
|
|
287
|
|
-
|
|
288
|
|
-function App() {
|
|
289
|
|
- const handleMount = React.useCallback((state: TLDrawState) => {
|
|
290
|
|
- state.selectAll()
|
|
291
|
|
- }, [])
|
|
292
|
|
-
|
|
293
|
|
- return <TLDraw onMount={handleMount} />
|
|
294
|
|
-}
|
|
295
|
|
-```
|
|
296
|
|
-
|
|
297
|
|
-To view the full documentation of the `TLDrawState` API, generate the project's documentation by running `yarn docs` from the root folder, then open the file at:
|
|
298
|
|
-
|
|

|
|
-```

|
|

|
|

-## Local Development
|
|
352
|
|
-
|
|
353
|
|
-From the root folder:
|
|
354
|
|
-
|
|
355
|
|
-- Run `yarn` to install dependencies.
|
|
356
|
|
-
|
|
357
|
|
-- Run `yarn start` to start the development server for the package and for the example.
|
|
358
|
|
-
|
|
359
|
|
-- Open `localhost:5420` to view the example project.
|
|
360
|
|
-
|
|
361
|
|
-**Note:** The multiplayer examples and endpoints currently require an API key from [Liveblocks](https://liveblocks.io/), however the storage services that are used in TLDraw are currently in alpha and (as of November 2021) not accessible to the general public. You won't be able to authenticate and run these parts of the project.

|
|
363
|
|
-Other scripts:
|
|
364
|
|
-
|
|
365
|
|
-- Run `yarn test` to execute unit tests via [Jest](https://jestjs.io).
|
|
366
|
|
-
|
|
367
|
|
-- Run `yarn docs` to build the docs via [ts-doc](https://typedoc.org/).
