feat(runtime): add generator-based runtime for the generator context pattern - #4
Merged
Conversation
…pattern Workflows request dependencies on demand via `yield*` instead of having them threaded through every function signature. `createRuntime<Context>()` returns `action` to define context-dependent operations, `call` and `provide` to compose workflows, and `run` to execute one against a real or mocked context. `Workflow<Return, Context>` carries the context type so the compiler keeps workflows from different runtimes apart, and `call`/`provide` operations are single-use since they own the generator instance they were given.

These four failures predate this branch — `main` has been red on the "Test and Release" workflow since 94af6d7. `run-p` aborts siblings on the first failure, so only `test:jsr` surfaced in the logs. - test:jsr: `parseRetryAfter`'s `now` parameter had no explicit type, which JSR's no-slow-types check rejects for public API symbols. - test:types: `lib` lost `dom` when it moved to es2024, so `RequestInfo` (src/api/api.test.ts) and `VoidFunction` (@tanstack/query-core's .d.ts, checked because skipLibCheck is false) no longer resolved. Emitted output is byte-identical with and without `dom`, so this is typecheck-only. - test:lint: `no-redundant-type-constituents` fired on the unresolved `RequestInfo`; fixed by the same `lib` change. - test:build: `sleep` grew to 180 B in a6b60a3 without its limit or README claim being updated.

Adds a new
runtimeutility implementing the generator context pattern:createRuntime<Context>()returnsactionto define context-dependent operations,call/provideto compose workflows, andrunto execute one against a real or mocked context, so workflows request dependencies viayield*instead of threading them through every signature.Workflow<Return, Context>carries the context type, so passing a workflow to a runtime that can't supply its dependencies is a compile error rather than a silentundefinedat runtime;call/provideoperations are single-use and throw on a secondyield*, since they own the generator instance they were given.Ships at 356 B brotli (375 B budget) with the usual README,
package.json/jsr.jsonexports,.size-limit.jsonentry, and 18 tests including@ts-expect-errorcases pinning the cross-runtime type checks.The single-use guard uses a small internal
singleUsehelper inruntime.lib.tsrather thanconcurrency/exactlyOnce, which is async-only and carries a passivepromiseproperty — more than this needs, and more bytes than the budget allows.🤖 Generated with Claude Code
