## Migration path
1. If any of your shapes implement `toSvg` for exports, you'll need to
replace your implementation with a new version that returns JSX (it's a
react component) instead of manually constructing SVG DOM nodes
2. `editor.getSvg` is deprecated. It still works, but will be going away
in a future release. If you still need SVGs as DOM elements rather than
strings, use `new DOMParser().parseFromString(svgString,
'image/svg+xml').firstElementChild`
## The change in detail
At the moment, our SVG exports very carefully try to recreate the
visuals of our shapes by manually constructing SVG DOM nodes. On its own
this is really painful, but it also results in a lot of duplicated logic
between the `component` and `getSvg` methods of shape utils.
In #3020, we looked at using string concatenation & DOMParser to make
this a bit less painful. This works, but requires specifying namespaces
everywhere, is still pretty painful (no syntax highlighting or
formatting), and still results in all that duplicated logic.
I briefly experimented with creating my own version of the javascript
language that let you embed XML like syntax directly. I was going to
call it EXTREME JAVASCRIPT or XJS for short, but then I noticed that we
already wrote the whole of tldraw in this thing called react and a (imo
much worse named) version of the javascript xml thing already existed.
Given the entire library already depends on react, what would it look
like if we just used react directly for these exports? Turns out things
get a lot simpler! Take a look at lmk what you think
This diff was intended as a proof of concept, but is actually pretty
close to being landable. The main thing is that here, I've deliberately
leant into this being a big breaking change to see just how much code we
could delete (turns out: lots). We could if we wanted to make this
without making it a breaking change at all, but it would add back a lot
of complexity on our side and run a fair bit slower

Previously, we were calling context menu `overrides` in a `useMemo`, so
they weren't updating reactively in the way that most of our other
schema overrides do. This diff calls `override` in a `useValue` instead
so it updates reactively.
It also fixes some issues with testing the `<Tldraw />` component:
currently we get a lot of errors in the console about updates not being
wrapped in `act`. These are caused by the fill patterns at different
zoom levels popping in without us waiting for them. Now, we have a
helper for rendering the tldraw component that waits for this correctly
and stops the error.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
- [x] Unit Tests
### Release Notes
- Context Menu overrides will now update reactively
This PR fixes a bug where the `version` was not updated during our last
release. This causes the assets not to load.
### Change Type
- [x] `patch` — Bug fix
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.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
- [x] Unit Tests
### Release Notes
- Fixes a bug that could cause crashes due to a re-render loop with HMR
#1989
Fixes pixel rounding when calculating css transformations for overlay
items. Also fixes issue where `editor.instanceState.devicePixelRatio`
wasn't properly updating.
TLDR; `width * window.devicePixelRatio` should be integer to avoid
rounding. `--tl-dpr-multiple` is smallest integer to multiply
`window.devicePixelRatio` such that its product is an integer.

### Change Type
- [x] `patch` — Bug fix
- [ ] `minor` — New feature
- [ ] `major` — Breaking change
- [ ] `dependencies` — Changes to package dependencies[^1]
- [ ] `documentation` — Changes to the documentation only[^2]
- [ ] `tests` — Changes to any test code only[^2]

package[^2]
- [ ] I don't know
[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version
### Test Plan
Would need to add a test checking when `window.devicePixelRatio`
changes, that `editor.instanceState.devicePixelRatio` is equal.

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`
### Change Type
- [x] `major` — Breaking change
### Test Plan
- [x] Unit Tests
- [x] End to end tests
### Release Notes
- [@tldraw/editor] lots, wip
- [@tldraw/ui] gone, merged to tldraw/tldraw
- [@tldraw/polyfills] gone, merged to tldraw/editor
- [@tldraw/primitives] gone, merged to tldraw/editor / tldraw/tldraw
- [@tldraw/indices] gone, merged to tldraw/editor
- [@tldraw/file-format] gone, merged to tldraw/tldraw

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.
