v0.19 lets a Manager write a whole batch of streamed rows in one store update, type-checks endpoint code about 2x faster, and fixes a round of TypeScript and Vue issues.

New APIs:

• Controller.set() with Array schemas - Write many entities in one store update with ctrl.set([Entity], rows), up to 95x faster than one set() per row

Performance:

• Faster TypeScript - Editors and tsc check RestEndpoint and resource() code about 2x faster with 40% less memory, catching every error they caught before

Other Improvements:

• Fix TypeScript 7 module resolution for package exports; imports now resolve to declaration files (#4019)
• renderDataHook() runs provider mount effects when the first render suspends (#4099)
• Controller.set() values are typed by the schema, so ctrl.set(new schema.All(Todo), 42) is a TypeScript error (#4133)
• process() gets typed params in new RestEndpoint(), .extend() and resource().extend(), so a wrong path parameter is a TypeScript error instead of undefined at runtime (#4183, #4184)
• Vue useSuspense() and useLive() keep the previous data while new arguments load, instead of returning undefined (#4131)
• Vue useSuspense() and useLive() send fetch errors after arguments change to onErrorCaptured() instead of an unhandled promise rejection (#4135)
• Vue useSuspense(), useDLE() and useFetch() no longer refetch stale data on every store update, so a controller.set() is not overwritten (#4134)
• Vue useSuspense() shows stale data on mount and refetches in the background, like React, instead of showing the <Suspense> fallback until the refetch finishes (#4169)
• Vue useDLE() and useCache() keep expired invalidIfStale data through unrelated store updates instead of getting stuck loading (#4142)
• Vue DataClientPlugin installs on Vue versions before 3.5 instead of throwing app.onUnmount is not a function (#4146)
• Vue DataClientPlugin garbage collects by default, matching React's DataProvider, so you no longer need to pass gcPolicy; how it decides what to remove (#4148)
• Vue composables accept getter arguments like () => ({ id: props.id }); they were typed to allow them but passed the function itself to the endpoint (#4115)
• Fix Cannot find name 'NoInfer' and export type errors on TypeScript 4.x with skipLibCheck off (#4138)
• Fix Entity, Endpoint, Union and RestEndpoint type errors on TypeScript 4.0–4.5 with skipLibCheck off (#4140)
• Entity classes can be used where an EntityInterface is expected (#4149); prepare pk() overrides for a future release
• useCache() and useDLE() return undefined for a deleted entity whose refetch failed, instead of a truthy Symbol that slipped past if (!data) checks; remove any workarounds (#4150)
• Vue useFetch() keeps its data from being garbage collected while mounted, like useSuspense(), so a configured gcPolicy no longer evicts prefetched data that components read later (#4152)
• Apps with Redux DevTools open no longer stutter in development on large stores or frequent updates; each update serializes 40-60x faster (#4163)
• resource().extend() with an object of endpoint overrides keeps endpoints added earlier with .extend('name', options) in its type, so using them is no longer a TypeScript error (#4184)
• Vue useFetch() is typed as the read-only Ref it returns, so promise.resolved (always undefined) is now a TypeScript error; read promise.value.resolved instead (#4114)
• Vue createDataClient() is deprecated, since it's internal to DataClientPlugin; install the plugin with app.use(DataClientPlugin, options) instead of calling it directly (#4193)

Breaking Changes:

• TypeScript 4.0 or later is required - the TypeScript 3.x declarations are removed (#4151)

Managers:

Manager APIs have been streamlined—flatter action shapes reduce code complexity and improve performance by minimizing distinct inline cache entries, while simpler configuration APIs make customization more delightful.

• Simplified action shapes
• Manager.middleware property
• getDefaultManagers() configuration

Performance:

• Immediate fetch calls - no more waiting for idle
• 30% smaller bundles by removing unnecessary polyfills
• 10% faster normalization, 32% faster denormalization

Schema/Data Modeling:

• Query joins with Object Schemas
• EntityMixin for composing Entity behavior
• Entity.pk() default uses id
• Dynamic invalidation via Entity.process()

Testing:

• renderDataHook() for simpler testing

Garbage Collection:

• GCPolicy - automatic garbage collection of stale data

Breaking Changes:

• NetworkManager fetches immediately
• action.payload -> action.response
• action.meta.args -> action.args
