Adds descriptions to examples.
They show as a list on the index page, and on individual examples they
show in a three-js style sidebar. For now, this is disabled completely
on mobile. Examples can still be opened in 'standalone' mode to get rid
of the sidebar.
Note: the 'view code' link won't work until after these changes are
merged.
There's a small impact on authoring examples: each one needs to live in
a folder with a README.md. At a minimum, the readme needs to look like
this:
```md
---
title: My Example
component: ./MyExample.tsx
---
Here is a 1-liner about my example
```
Optionally, you can:
- Add `hide: true` to the frontmatter to remove the example from the
list (you can skip the description this way)
- Add `order: 3` to control the order in which the example appears.
They're alphabetical otherwise
- Add some more description or links to docs below a `---`. This won't
show in the listing, but will be visible on GitHub and on the example
page itself.
As a follow-up, I'd like to add an 'Open in CodeSandbox' link to each
example. These won't work until we've made a release with these examples
(as our special examples codesandbox is tied to our release process) but
the code is there & ready to go!
Have a play, let me know what you think!

This is an attempt at #1989. The big issue there is when `shapeUtils`
change when you're relying on tldraw to provide you with the store
instead of providing your own. Our `useTLStore` component had a bug
where it would rely on effects & a ref to detect when its options had
changed whilst still scheduling updates. Fresh opts would come in, but
they'd be different from the ones in the ref, so we'd schedule an
update, so the opts would come in again, but they'd still be different
as we hadn't run effects yet, and we'd schedule an update again (and so
on).
This diff fixes that by storing the previous opts in state instead of a
ref, so they're updating in lockstep with the store itself. this
prevents the update loop.
There are still situations where we can get into loops if the developer
is passing in custom tools, shapeUtils, or components but not memoising
them or defining them outside of react. As a DX improvement, we do some
auto-memoisation of these values using shallow equality to help with
this issue.

This PR improves our method for handling images, which is especially
useful when using a local tldraw editor. Previously, we were only
downsample images that were above the browser's maximum size. We now
downsample all images. This will result in smaller images in almost all
cases. It will also prevent very large jpeg images from being converted
to png images, which could often lead to an increase in file size!
### Change Type
- [x] `minor` — New feature
### Test Plan
1. Add some images (jpegs or pngs) to the canvas.
### Release Notes
- Improved image rescaling.
After the dialog is closed the `body` still has `pointer-events: none`

make this work. Otherwise some old dependencies are kept and make this
not work.

This PR moves code between our packages so that:
- @tldraw/editor is a “core” library with the engine and canvas but no
shapes, tools, or other things
- @tldraw/tldraw contains everything particular to the experience we’ve
built for tldraw
At first look, this might seem like a step away from customization and
configuration, however I believe it greatly increases the configuration
potential of the @tldraw/editor while also providing a more accurate
reflection of what configuration options actually exist for
@tldraw/tldraw.
## Library changes
@tldraw/editor re-exports its dependencies and @tldraw/tldraw re-exports
@tldraw/editor.
- users of @tldraw/editor WITHOUT @tldraw/tldraw should almost always
only import things from @tldraw/editor.
- users of @tldraw/tldraw should almost always only import things from
@tldraw/tldraw.
- @tldraw/polyfills is merged into @tldraw/editor
- @tldraw/indices is merged into @tldraw/editor
- @tldraw/primitives is merged mostly into @tldraw/editor, partially
into @tldraw/tldraw
- @tldraw/file-format is merged into @tldraw/tldraw
- @tldraw/ui is merged into @tldraw/tldraw
Many (many) utils and other code is moved from the editor to tldraw. For
example, embeds now are entirely an feature of @tldraw/tldraw. The only
big chunk of code left in core is related to arrow handling.
## API Changes
The editor can now be used without tldraw's assets. We load them in
@tldraw/tldraw instead, so feel free to use whatever fonts or images or
whatever that you like with the editor.
All tools and shapes (except for the `Group` shape) are moved to
@tldraw/tldraw. This includes the `select` tool.
You should use the editor with at least one tool, however, so you now
also need to send in an `initialState` prop to the Editor /
<TldrawEditor> component indicating which state the editor should begin
in.
The `components` prop now also accepts `SelectionForeground`.
The complex selection component that we use for tldraw is moved to
@tldraw/tldraw. The default component is quite basic but can easily be
replaced via the `components` prop. We pass down our tldraw-flavored
SelectionFg via `components`.
Likewise with the `Scribble` component: the `DefaultScribble` no longer
uses our freehand tech and is a simple path instead. We pass down the
tldraw-flavored scribble via `components`.
The `ExternalContentManager` (`Editor.externalContentManager`) is
removed and replaced with a mapping of types to handlers.
- Register new content handlers with
`Editor.registerExternalContentHandler`.
- Register new asset creation handlers (for files and URLs) with
`Editor.registerExternalAssetHandler`

This PR incorporates a crc method from
https://github.com/alexgorbatchev/crc into the library, removing a peer
dependency on `buffer`. This was causing build errors in apps that did
not include the buffer library. (Our codebase included buffer because of
vsce.)
### Change Type
- [x] `patch`
### Release Notes
- [@tldraw/editor] Remove peer dependency on buffer.
tldraw-zero themed follow-ups to the styles API added in #1580.
- Removed style related helpers from `ShapeUtil`
- `editor.css` no longer includes the tldraw default color palette.
Instead, a global `DefaultColorPalette` is defined as part of the color
style. If developers wish to cusomise the colors, they can mutate that
global.
- `ShapeUtil.toSvg` no longer takes font/color. Instead, it takes an
"svg export context" that can be used to add `<defs>` to the exported
SVG element. Converting e.g. fonts to inlined data urls is now the
responsibility of the shapes that use them rather than the Editor.
- `usePattern` is not longer a core part of the editor. Instead,
`ShapeUtil` has a `getCanvasSvgDefs` method for returning react
components representing anything a shape needs included in `<defs>` for
the canvas.
- The shape-specific cleanup logic in `setStyle` has been deleted. It
turned out that none of that logic has been running anyway, and instead
the relevant logic lives in shape `onBeforeChange` callbacks already.

This PR improves the ergonomics of `ShapeUtil` classes.
### Cached methods
First, I've remove the cached methods (such as `bounds`) from the
`ShapeUtil` class and lifted this to the `Editor` class.
Previously, calling `ShapeUtil.getBounds` would return the un-cached
bounds of a shape, while calling `ShapeUtil.bounds` would return the
cached bounds of a shape. We also had `Editor.getBounds`, which would
call `ShapeUtil.bounds`. It was confusing. The cached methods like
`outline` were also marked with "please don't override", which suggested
the architecture was just wrong.
The only weirdness from this is that utils sometimes reach out to the
editor for cached versions of data rather than calling their own cached
methods. It's still an easier story to tell than what we had before.
### More defaults
We now have three and only three `abstract` methods for a `ShapeUtil`:
- `getDefaultProps` (renamed from `defaultProps`)
- `getBounds`,
- `component`
- `indicator`
Previously, we also had `getCenter` as an abstract method, though this
was usually just the middle of the bounds anyway.
### Editing bounds
This PR removes the concept of editingBounds. The viewport will no
longer animate to editing shapes.
### Active area manager
This PR also removes the active area manager, which was not being used
in the way we expected it to be.
### Dpr manager
This PR removes the dpr manager and uses a hook instead to update it
from React. This is one less runtime browser dependency in the app, one
less thing to document.
### Moving things around
This PR also continues to try to organize related methods and properties
in the editor.
### Change Type
- [x] `major` — Breaking change
### Release Notes
- [editor] renames `defaultProps` to `getDefaultProps`
- [editor] removes `outline`, `outlineSegments`, `handles`, `bounds`
- [editor] renames `renderBackground` to `backgroundComponent`
This reverts commit b6716a3750.
Not sure why, but this introduced a `/// <references />` comment in the
tldraw/tldraw api-report.md file that doesn't show up when you build
from brivate. Reverting for now.
### Change Type
- [x] `dependencies` — Changes to package dependencies[^1]
### Test Plan

### Release Notes
-
Removes `propsForNextShape` and replaces it with the new styles API.
Changes in here:
- New custom style example
- `setProp` is now `setStyle` and takes a `StyleProp` instead of a
string
- `Editor.props` and `Editor.opacity` are now `Editor.sharedStyles` and
`Editor.sharedOpacity`
- They return an object that flags mixed vs shared types instead of
using null to signal mixed types
- `Editor.styles` returns a `SharedStyleMap` - keyed on `StyleProp`
instead of `string`
- `StateNode.shapeType` is now the shape util rather than just a string.
This lets us pull the styles from the shape type directly.
- `color` is no longer a core part of the editor set on the shape
parent. Individual child shapes have to use color directly.
- `propsForNextShape` is now `stylesForNextShape`
- `InstanceRecordType` is created at runtime in the same way
`ShapeRecordType` is. This is so it can pull style validators out of
shape defs for `stylesForNextShape`
- Shape type are now defined by their props rather than having separate
validators & type defs
### Change Type
- [x] `major` — Breaking change
### Test Plan
1. Big time regression testing around styles!
2. Check UI works as intended for all shape/style/tool combos

This diff reverts 09c36781 and tweaks how some of our linting was
working.
I'm not actually sure what caused the regression that 09c36781 was
fixing - it was something to do with typescript being used to transpile
eslintrc.js, but that being excluded from the tsconfig for those
projects. I fixed that by removing `rootDir` from those, but that
revealed some other issues with files not getting ignored correctly.
I fixed the ignoring issue with a change I've wanted to make to these
scripts for a while: only running them on files that are actually
tracked by git, instead of on everything with a relevant extension. A
side effect of that is that we have to re-implement .eslintignore
support ourselves, but that's very straight forward: the `ignore`
package that eslint uses is very easy to include.

### Release Notes
[internal-only]
This PR updates our user-facing APIs for the Tldraw and TldrawEditor
components, as well as the Editor (App). It mainly incorporates surface
changes from #1450 without any changes to validators or migrators,
incorporating feedback / discussion with @SomeHats and @ds300.
Here we:
- remove the TldrawEditorConfig
- bring back a loose version of shape definitions
- make a separation between "core" shapes and "default" shapes
- do not allow custom shapes, migrators or validators to overwrite core
shapes
- but _do_ allow new shapes
## `<Tldraw>` component
In this PR, the `Tldraw` component wraps both the `TldrawEditor`
component and our `TldrawUi` component. It accepts a union of props for
both components. Previously, this component also added local syncing via
a `useLocalSyncClient` hook call, however that has been pushed down to
the `TldrawEditor` component.
## `<TldrawEditor>` component
The `TldrawEditor` component now more neatly wraps up the different ways
that the editor can be configured.
## The store prop (`TldrawEditorProps.store`)
There are three main ways for the `TldrawEditor` component to be run:
1. with an externally defined store
2. with an externally defined syncing store (local or remote)
3. with an internally defined store
4. with an internally defined locally syncing store
The `store` prop allows for these configurations.
If the `store` prop is defined, it may be defined either as a `TLStore`
or as a `SyncedStore`. If the store is a `TLStore`, then the Editor will
assume that the store is ready to go; if it is defined as a SyncedStore,
then the component will display the loading / error screens as needed,
or the final editor once the store's status is "synced".
When the store is left undefined, then the `TldrawEditor` will create
its own internal store using the optional `instanceId`, `initialData`,
or `shapes` props to define the store / store schema.
If the `persistenceKey` prop is left undefined, then the store will not
be synced. If the `persistenceKey` is defined, then the store will be
synced locally. In the future, we may also here accept the API key /
roomId / etc for creating a remotely synced store.
The `SyncedStore` type has been expanded to also include types used for
remote syncing, e.g. with `ConnectionStatus`.
## Tools
By default, the App has two "baked-in" tools: the select tool and the
zoom tool. These cannot (for now) be replaced or removed. The default
tools are used by default, but may be replaced by other tools if
provided.
## Shapes
By default, the App has a set of "core" shapes:
- group
- embed
- bookmark
- image
- video
- text
That cannot by overwritten because they're created by the app at
different moments, such as when double clicking on the canvas or via a
copy and paste event. In follow up PRs, we'll split these out so that
users can replace parts of the code where these shapes are created.

This PR replaces our webdriver end to end tests with playwright tests.
It:
- replaces our webdriver workflow with a new e2e workflow based on
playwright
- removes the webdriver project
- adds e2e tests to our examples app
- replaces all `data-wd` attributes with `data-testid`
### Coverage
Most of the tests from our previous e2e tests are reproduced here,
though there are some related to our gestures that will need to be done
in a different way—or not at all. I've also added a handful of new
tests, too.
### Where are they
The tests are now part of our examples app rather than being in its own
different app. This should help us test our different examples too. As
far as I can tell there are no downsides here in terms of the regular
developer experience, though they might complicate any CodeSandbox
projects that are hooked into the examples app.

Our private tlsync package currently depends on the editor package,
which balloons the size of the cloudflare worker. It also makes it so
that any change to any package triggers a worker refresh, which makes
working on multiplayer stuff kinda miserable.
This is the first PR to fix that problem.
The second PR will need to resolve TLSyncClient's dependency on the
debugFlags somehow. Easiest would be to just remove the offending flag,
but we might want cross-bublic debug flags at some point in the future
so I'll try to find a low-cost way to make that happen while making
`tlsync` not depend on `editor`.
cc @TodePond since you added the flag in question
(`tldrawResetConnectionEveryPing`)
### Release Note
- internal moving stuff around
Right now this examples app looks exactly the same as our old examples
app, but there are a couple of tiny differences:
- We use `vite` instead of our own esbuild setup for development and
bundling
- We use `@tldraw/assets` for smart asset hashing instead of copying the
assets to a public folder
You can use `@tldraw/assets` with vite with a bunch of extra config, but
it (plus a bunch of other bundlers) also support a special syntax for
specifying asset urls: `new URL('./my/asset.svg',
import.meta.url).href`. This approach is more standards-complient, but
doesn't work with every bundler just yet. This diff also adds a
url-based version of `@tldraw/assets`, although I'd like to tweak the
entry point - right now you need to import from
`@tldraw/assets/lib/urls`, but i'd like to find a way to get this to
`@tldraw/assets/urls` or something at some point.
There are a couple other extra fixes in here:
- vscode builds were broken, they're fixed now!
- there's also a little tweak to the `getBundlerAssetUrls` API to allow
passing in a function instead of an object for URL formatting
- there are new internal-only functions for injecting asset urls
globally instead of passing them in via react props. this means we can
get the benefits of cacheable URLs without having to clutter our
examples by passing them in
In this PR I'm adding new versions of the `LiveCollaborators` and
`Collaborators` components for the ephemeral state work. They are behind
a feature flag for now.
Temporarily moving us to a prerelease of this dep. This resolves an
issue where the mobile style menu popover couldn't be closed by tapping
the style button again. See
https://github.com/radix-ui/primitives/issues/2105 for details
This PR adds
- A new `TLInstancePresence` record type, to collect info about the
presence state in a particular instance of the editor. This will
eventually be used to sync presence data instead of sending
instance-only state across the wire.
- **Record Scopes**
`RecordType` now has a `scope` property which can be one of three
things:
- `document`: the record belongs to the document and should be synced
and persisted freely. Currently: `TLDocument`, `TLPage`, `TLShape`, and
`TLAsset`
- `instance`: the record belongs to a single instance of the store and
should not be synced at all. It should not be persisted directly in most
cases, but rather compiled into a kind of 'instance configuration' to
store alongside the local document data so that when reopening the
associated document it can remember some of the previous instance state.
Currently: `TLInstance`, `TLInstancePageState`, `TLCamera`, `TLUser`,
`TLUserDocument`, `TLUserPresence`
- `presence`: the record belongs to a single instance of the store and
should not be persisted, but may be synced using the special presence
sync protocol. Currently just `TLInstancePresence`
This sets us up for the following changes, which are gonna be pretty
high-impact in terms of integrating tldraw into existing systems:
- Removing `instanceId` as a config option. Each instance gets a
randomly generated ID.
- We'd replace it with an `instanceConfig` option that has stuff like
selectedIds, camera positions, and so on. Then it's up to library users
to get and reinstate the instance config at persistence boundaries.
- Removing `userId` as config option, and removing the `TLUser` type
altogether.
- We might need to revisit when doing auth-enabled features like locking
shapes, but I suspect that will be separate.
