feat(client,react,vue,solid,svelte,angular): action hooks for every adapter - #422
Merged
Conversation
…dapter
Actions were the one procedure kind with no adapter surface. Every adapter
shipped a query and a mutation primitive and nothing for actions, so each app
reached for the raw client and re-derived the same pending/error wrapper by
hand.
@lunora/client gains `createActionRunner`, the sibling of the existing
`createMutationRunner`: it ref-counts overlapping invocations into `setPending`
so the flag clears only once the last settles, normalizes a thrown non-Error,
and routes success/failure to the adapter's own reactive setters before
re-throwing. Deliberately a separate export rather than a reuse of the mutation
runner, because the two differ in the option type they forward.
Each adapter then binds it to its own primitive, in its own idiom:
react useAction(ref) -> { call, data, error, isError, pending, reset }
vue useAction(ref) -> refs
solid createAction(ref) -> accessors (+ createActionForClient seam)
svelte action(ref) / action(c, r) -> stores, matching mutation's overloads
angular runAction(ref, args, opts) -> a plain promise
Angular stays a plain function on purpose: its adapter models writes as calls
rather than reactive handles, because they fire from event handlers where a
signal-returning primitive has nothing to bind to.
All five are narrower than their mutation counterparts: no optimistic or
optimisticUpdate options. An optimistic update patches the subscription cache
on the assumption a write will land; an action is not a write — it runs in the
Worker, may call a third party, and has no declared effect on any query.
Offering the option would imply a rollback guarantee nothing can honour.
Tests cover the runner itself (including that it re-throws the same Error
instance it hands the sink) plus each adapter's binding: args/options
forwarding, the pending round trip, ref-counting across overlapping calls, and
that a failure rejects rather than being swallowed. The vue and angular test
fakes gain an action surface alongside their mutation one.
client and react are Core tier and vue/solid/svelte are Stable adapters, so
six api-snapshots move with this — including lunora.api.md, which re-exports
the client. angular is not under the snapshot guard.
client 679/680 (1 expected fail), react 158, vue 94, solid 85, svelte 99,
angular 111; lint and tsc clean across all six; api:check green.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
React does not normalize non-Error rejections.
The other adapters route failures through createActionRunner, which converts a non-Error rejection into an Error (packages/client/src/action-runner.ts line 65). This hook passes the raw rejection through TanStack Query. ActionHook.error is typed Error | null at line 26, so a thrown string or object makes error.message undefined at runtime while the type says otherwise.
Normalize in mutationFn so all adapters expose the same error contract.
🐛 Proposed fix to normalize rejections
- mutationFn: async ({ args, options }) => client.action(function_, args, options),
+ mutationFn: async ({ args, options }) => {
+ try {
+ return await client.action(function_, args, options);
+ } catch (error) {
+ throw error instanceof Error ? error : new Error(String(error));

The action hooks shipped with no prose. Every one of these packages already
documents its mutation primitive in `docs/index.mdx`, so the omission read as
"actions have no adapter surface" — the exact gap the hooks were meant to close.
Each adapter page gains a section next to its mutation one, in that page's own
idiom and shape: React's terse `{ call, pending, data, error, isError, reset }`
paragraph, Vue's `ActionHandle` block over `Ref<>`, Solid's over `Accessor<>`,
Svelte's over `Readable<>` plus the client overload note, Angular's plain
`runAction(fn, args, options?)` with the reason it is a function rather than a
handle. Export tables and re-exported-type lists pick up the new symbols.
`@lunora/client` gains an Actions section covering `client.action` and
`createActionRunner` — the runner is only reachable when writing a custom
adapter, so it is documented as that seam rather than as app-facing API.
`frameworks/bring-your-framework` is where the uniform-across-adapters contract
is asserted, so the per-idiom naming (`useAction` / `createAction` / `action` /
`runAction`) and the deliberate narrowing land there too.
Each page states the same reason for that narrowing: an optimistic update
patches the subscription cache on the assumption a write will land, and an
action is not a write.
Every signature checked against the source and against client.api.md rather
than transcribed from the commit message. `check-doc-imports` and prettier
green.

Limit the runner claim to the reactive adapters.
runAction is an Angular action primitive, but packages/angular/src/run-action.ts calls client.action directly. Line 157 says every adapter action primitive uses createActionRunner, while the list omits Angular.
State that React, Vue, Solid, and Svelte use the shared runner. Document Angular as a direct promise-based invocation if needed.

…ty manifest Two things the action-hooks commit missed, both caught by looking at CI rather than trusting the local run I claimed was clean. `action-runner.test.ts` tripped `vitest/prefer-expect-assertions` at all five tests, and eslint runs with `--max-warnings=0`, so CI was red. Its own sibling `mutation-runner.test.ts` opens every test with `expect.assertions(n)` — the new file simply didn't follow the convention next to it. Counts are per test, not a blanket `hasAssertions`, matching the sibling. `adapter-export-parity.test.ts` had no `action` entry. That manifest exists to turn "some adapter quietly lost a feature" into a red test, and its own comment says to add a feature once it ships in more than one adapter — actions now ship in all five. Without the entry a future adapter dropping its action primitive would have gone unnoticed, which is the exact failure the file was written to prevent. Angular is registered as `runAction` rather than the bare `action` the naming convention predicts, with the reason recorded inline. The parity entry is not bookkeeping: it adds five real assertions that resolve each adapter's barrel and confirm the export is present, so it verifies the five bindings rather than asserting them. client 684 passed, 1 expected fail (685); eslint and prettier green.

`createActionRunner` and `createMutationRunner` differed by a single token
(`client.action` vs `client.mutation`). The comment defending the split
claimed collapsing them would offer optimistic updates on actions, but the
runner never reads `options` — it takes them as an opaque parameter and hands
them straight to the transport. What actually keeps `optimisticUpdate` off an
action is the adapter's exported handle type.
Both are now one `createCallRunner(invoke, sinks)` taking a pre-bound thunk,
so the option type is inferred from the closure instead of hard-coded per
procedure kind, and `ActionCapableClient` / `MutationCapableClient` are gone.
This fixes a real defect once for both, where patching the two separately
would have fixed it once: neither runner had a sequence guard, so overlapping
calls settled last-to-finish rather than last-to-start. On a double-click
whose first call is slow and second is fast, the UI settled on the FIRST
click's result; with a mixed outcome it could hold the second call's `data`
and the first call's `error` at the same time, showing a failure banner for a
call that succeeded. Each invocation now takes a monotonic token and writes
the value sinks only while it is still the most recent one — the same fix
`createMutatorRunner` already carries. `pending` stays ref-counted across all
in-flight calls and the rejection still propagates to its own caller.
Per-call action options are now the exported `ActionCallOptions` on
`LunoraClient`, next to `MutationCallOptions` and for the same reason: three
declarations of `{ shardKey?: string }` existed and the canonical one was
anonymous, so adding an option to `client.action` would have left every
adapter silently unable to forward it.
BREAKING CHANGE: `createActionRunner` and `createMutationRunner` are replaced
by `createCallRunner`, which takes a thunk instead of `(client, fn)`. The
unused `ActionRunnerSinks` / `MutationRunnerSinks` exports are dropped.

Three defects in one hook, all from taking TanStack's mutation defaults on a
call that is not a mutation.
`useTanStackMutation` was created without `networkMode`, so it defaulted to
`"online"`. `Mutation.execute` dispatches `pending` and awaits `onMutate` —
which set the hook's `pending` — BEFORE starting the retryer, whose `canStart`
gates on `onlineManager.isOnline()`. Offline, `call()`'s promise never settled:
the spinner stuck forever, `client.action` was never invoked so no error
surfaced either, and on reconnect `resumePausedMutations()` fired the action
minutes later, after the user had given up and possibly navigated away. An
action may call a third party. `networkMode: "always"` makes it fail fast, as
it already does in the other four adapters, which go straight to
`client.action`.
`retry` was inherited from whatever QueryClient the provider resolved. The
default one pins `retry: 0`, but an app-supplied client or a parent
`<QueryClientProvider>` wins, and `new QueryClient({ defaultOptions: {
mutations: { retry: 2 } } })` is a common recipe. `client.action` sends no
`mutationId`, so there is nothing server-side to dedupe against: a charge that
succeeded and then 502'd on the response was silently fired twice more. It is
now pinned in the hook's own options. `useMutation` legitimately keeps both
defaults — it carries a `mutationId` and an offline queue.
The hook also hand-rolled the ref-counted request state machine with `useRef`
+ `onMutate`/`onSettled` instead of using the shared runner the other three
adapters build on, so a fix would have landed in three of six. It now wraps
`mutateAsync` in `createCallRunner`, and holds `data`/`error` in the hook
rather than reading them off the mutation observer — which is what makes it
honour the one lifecycle contract now documented for every adapter: `data` and
`error` both track the LATEST invocation rather than the last to settle, a
success clears `error`, a failure leaves the previous `data` in place, and
`reset()` clears both without cancelling an in-flight call. React was the odd
one out on all three points. Storing the result through a thunk keeps a
function-valued server result from being mistaken for a `useState` updater.
BREAKING CHANGE: `ActionHook.error` is `Error | undefined` rather than
`Error | null`, matching the other adapters, and `isError` is dropped —
branch on `error` instead. `UseActionCallOptions` is gone; the canonical
`ActionCallOptions` from `@lunora/client` replaces it.

Vue, Solid and Svelte each re-asserted ref-counted overlapping-pending — behaviour that lives entirely in the shared runner and is already covered there, so ~90 lines proved the same core three times while the parts only an adapter test can reach went unasserted. Traded for what is actually adapter-specific: that the runner's writes land in a reactive cell the framework notifies on (a Vue `watch` fires, a Solid `createEffect` re-runs, a Svelte store subscriber is called) rather than in a plain variable that would pass every value assertion and still never re-render. Adds the data-after-error case to all three — nothing asserted the sticky-data half of the lifecycle contract — plus the function-valued-result case for Solid, whose `setData(() => result)` thunk-wrap had no test at all and whose absence would have Solid invoke a server result instead of storing it.

The API docs panel told users "Actions have no React hook — call them through the client", and its React tab fell back to the client snippet for every action. `@lunora/react` now ships `useAction`, so both the note and the fallback were wrong on screen. The `REACT_HAS_ACTION_HOOK` flag existed to keep the panel and its tests reading one fact and to be flipped when a hook landed; with the hook shipped there is nothing left for it to guard, so it and the note string are gone and the action branch emits the hook.

That is the better call and this branch's `containersExec` commit is dropped: `exec` is a method on the accessor `containers` already gates, not a separately imported surface, so codegen has no independent usage signal to act on and a second rating could never change an outcome. - #422 (adapter action hooks) landed with one `createCallRunner` instead of the `createActionRunner`/`createMutationRunner` pair proposed here. Both sets of commits are therefore dropped from this branch rather than replayed, since replaying them would conflict with the merged-and-better versions. What that leaves, and what changes here: `apps/builder`'s terminal called `client.action` through `useLunora()` with a comment naming the adapter hook as the follow-up. The follow-up shipped, so the pane now uses `useAction`. Its `pending` is ref-counted across overlapping invocations, so the local `busy` flag and the `finally` that cleared it are both gone. Two comments that described the old shape are corrected rather than left to rot, and the plan's two execution notes now record the merged outcome instead of asserting a workaround that is no longer true. `api-snapshots/vite.api.md` is regenerated. The `hasAgents` parameter added for the builder moves a Core-tier signature, and the commit that had recorded it was one of the dropped ones — so the gate went red again exactly as it did the first time. One line moves, and it is the expected one. `pnpm-lock.yaml` is regenerated from alpha's rather than merged, per CLAUDE.md: a hand-resolved lockfile installs a tree nobody has, and CI builds the merge ref. Verified against current alpha after a full `build:packages`: builder typecheck clean (app and `_generated`), 52/52 builder tests, `vite build` succeeds, @lunora/vite 200/200, ESLint clean, `api:check` green across all 48 snapshots, `lint:package-json` green.

Summary
Actions were the one procedure kind with no adapter surface at all. Every adapter shipped a query and a mutation primitive and nothing for actions, so each app reached for the raw client and re-derived the same pending/error wrapper by hand. Angular likewise had
mutateand no counterpart.@lunora/clientgainscreateActionRunner— the sibling of the existingcreateMutationRunnerthat the three reactive adapters already share. It ref-counts overlapping invocations intosetPending(so the flag clears only once the last settles), normalizes a thrown non-Error, and routes success/failure to the adapter's own reactive setters before re-throwing. Deliberately a separate export rather than a reuse of the mutation runner, because the two differ in the option type they forward.Each adapter then binds it to its own primitive, in its own idiom:
@lunora/reactuseAction(ref)→{ call, data, error, isError, pending, reset }@lunora/vueuseAction(ref)→ refs@lunora/solidcreateAction(ref)→ accessors, plus acreateActionForClientseam for stub injection@lunora/svelteaction(ref)/action(client, ref)→ stores, matchingmutation's overloads@lunora/angularrunAction(ref, args, opts)→ a plain promiseTwo decisions worth a reviewer's attention
Angular stays a plain function, not a reactive handle. Its adapter models writes as calls rather than handles because they fire from event handlers, where a signal-returning primitive has nothing to bind to —
mutateis shaped the same way. Matching the other four here would have been consistency for its own sake.All five are narrower than their mutation counterparts: no
optimistic/optimisticUpdate. An optimistic update patches the subscription cache on the assumption a write will land; an action is not a write — it runs in the Worker, may call a third party, and has no declared effect on any query. Offering the option would imply a rollback guarantee nothing can honour.Linked issues
None.

Six API snapshots move.
clientandreactare Core tier,vue/solid/svelteare Stable adapters, andlunora.api.mdmoves because the umbrella re-exports the client.angularis deliberately outside the snapshot tiers, so its newrunActionis not under the guard — worth knowing when reviewing it, since nothing will catch a later signature change there.The test fakes grew.
packages/vue/__tests__/fake-client.tsandpackages/angular/__tests__/fake-client.tsgain anactionsurface alongside their existingmutationone. Solid needed no fake change — its tests inject a narrowActionClientstub, which is the same seamcreateMutationForClientalready provides.One assertion I deliberately loosened. The runner's ref-counting test asserts the absence of a
falsepush while a call is still in flight, not a particular count oftrues. The first call'sfinallylegitimately re-pushestruebecause the second is still running, so a count assertion would pin an implementation detail and fail on a harmless refactor.Docs, in the second commit. An earlier revision of this description claimed no
apps/docspage covered actions and that none was therefore updated. That was wrong: all six packages document their mutation primitive indocs/index.mdx, whichapps/docsrenders, so shipping the hooks without prose would have left the docs asserting that actions have no adapter surface — the exact gap this PR closes.8135abdfixes it. Each adapter page gains a section next to its mutation one, written in that page's own shape (Vue'sActionHandleblock overRef<>, Solid's overAccessor<>, Svelte's overReadable<>plus the overload note, React's terse paragraph, Angular's plain-function form with the reason it is not a handle), and export tables pick up the new symbols.@lunora/clientdocumentsclient.actionandcreateActionRunneras the custom-adapter seam.frameworks/bring-your-frameworkis where the uniform-across-adapters contract is asserted, so the per-idiom naming and the deliberate narrowing land there too.🤖 Generated with Claude Code
