New stickies & performance improvements

This tldraw release has loads of performance improvements, plus completely redesigned sticky notes. Check out our release notes for for more details on those.

Breaking changes

New migrations (#3220)
  • The Migrations type is now called LegacyMigrations.

  • The serialized schema format (e.g. returned by StoreSchema.serialize() and Store.getSnapshot()) has changed. You don't need to do anything about it unless you were reading data directly from the schema for some reason. In which case it'd be best to avoid that in the future! We have no plans to change the schema format again (this time was traumatic enough) but you never know.

  • compareRecordVersions and the RecordVersion type have both disappeared. There is no replacement. These were public by mistake anyway, so hopefully nobody had been using it.

  • compareSchemas is gone. Comparing the schemas directly is no longer really possible since we introduced some fuzziness. The best thing to do now to check compatibility is to call schema.getMigraitonsSince(prevSchema) and it will return an error if the schemas are not compatible, an empty array if there are no migrations to apply since the prev schema, and a nonempty array otherwise.

    Generally speaking, the best way to check schema compatibility now is to call store.schema.getMigrationsSince(persistedSchema). This will throw an error if there is no upgrade path from the persistedSchema to the current version.

  • defineMigrations has been deprecated and will be removed in a future release. For upgrade instructions see updating legacy shape migrations

  • migrate has been removed. Nobody should have been using this but if you were you'll need to find an alternative. For migrating tldraw data, you should stick to using schema.migrateStoreSnapshot and, if you are building a nuanced sync engine that supports some amount of backwards compatibility, also feel free to use schema.migratePersistedRecord.

  • the Migration type has changed. If you need the old one for some reason it has been renamed to LegacyMigration. It will be removed in a future release.

  • the Migrations type has been renamed to LegacyMigrations and will be removed in a future release.

  • the SerializedSchema type has been augmented. If you need the old version specifically you can use SerializedSchemaV1

Input buffering (#3223)

Events are now buffered and sent to state nodes every tick, instead of immediately. This unlocks some big performance improvements, but could introduce some subtle issues with any custom tools you might have. Make sure you test any custom tools thoroughly!

React-powered SVG exports (#3117)
  1. If any of your shapes implement toSvg for exports, you'll need to replace your implementation with a new version that returns JSX instead of manually constructing SVG DOM nodes.
  2. editor.getSvg is deprecated. It still works, but will be going away in a future release. Instead, use editor.getSvgElement or editor.getSvgString.
Component-based toolbar customisation API (#3067)

If you're using the toolbar callback to override the items in the toolbar at the bottom of the default tldraw UI, you need to switch to using the new Toolbar component override.

See the custom toolbar example for more details.
