Generated documentation outline

Selected javascript guides​

The fixed, symbol-backed guide plan used by this isolated hosted publication Flyte canary.

Register and call typed hooks​

Build a source-grounded TypeScript guide that declares a hook contract, creates a typed Hookable instance with createHooks, registers handlers with hook, and awaits callHook. HARD OUTPUT CONTRACT: the entire submitted Markdown must contain exactly two fenced code blocks total, both labeled typescript. These two blocks are the complete fence budget and override general style guidance to add variations, troubleshooting, or more examples. Fence 1 must demonstrate typed registration and sequential dispatch. Fence 2 must capture and invoke the unregister function returned by hook. Each designated fence must contain its own named ESM imports and type declarations. Every hook callback contract must return void or a promise that resolves with no value, and registered handlers must produce observable effects without returning a payload. Do not use a callback type that resolves to a string or return a result value. Outside those two fences, use prose and inline code only; do not add installation, import-only, output, error-handling, internal-implementation, alternative, troubleshooting, or explanatory fences in any language or with tilde markers. Explain behavior only through documented public APIs and observable semantics; do not name, describe, or make claims about registries, storage mechanisms, _hooks, proxy wrappers, array storage, or any other internal implementation detail. Explain in prose that a handler error rejects callHook rather than being swallowed; do not demonstrate that point in another block. Before calling submit_content, count fenced blocks in the complete Markdown and revise it unless the total is exactly two. Do not use default imports, CommonJS require, invented APIs, or an unawaited callHook promise. If a fence declares and invokes an async helper, await that example entry point so no locally created promise is left floating. FINAL PROSE CHECK: remove every explanation of how Hookable is implemented and every use of the words internal, internally, registry, storage, _hooks, proxy, array storage, splice, or splicing; describe only public method calls and their observable results.

Run one-shot and parallel hooks​

Build a source-grounded TypeScript guide to one-shot and parallel hook execution with hookOnce, removeHook, callHook, and callHookParallel. HARD OUTPUT CONTRACT: the entire submitted Markdown must contain exactly two fenced code blocks total, both labeled typescript. These two blocks are the complete fence budget and override general style guidance to add variations, edge cases, or more examples. Fence 1 must await the same hook twice and demonstrate that a hookOnce handler runs only on the first call. Fence 2 must register a named handler, await parallel dispatch, and remove that same handler. Each designated fence must contain its own named ESM imports and type declarations. Every hook callback contract must return void or a promise that resolves with no value. In fence 2, declare the hook-map callback type as the TypeScript union of void and a Promise whose generic argument is void, and make the named handler produce observable effects without returning a payload; do not use a callback type that resolves to a string, return a result value, or claim that callHookParallel collects handler results. Outside those two fences, use prose and inline code only; do not add installation, import-only, output, unregistration-alternative, internal-implementation, variation, or explanatory fences in any language or with tilde markers. Explain behavior only through documented public APIs and observable semantics; do not name, describe, or make claims about _hooks, proxy wrappers, array storage, or any other internal implementation detail. Before calling submit_content, count fenced blocks in the complete Markdown and revise it unless the total is exactly two. Do not use default imports, access undocumented internals, invent APIs, or leave hook promises unawaited. If a fence declares and invokes an async helper, await that example entry point so no locally created promise is left floating. FINAL PROSE CHECK: remove every explanation of how Hookable is implemented and every use of the words internal, internally, _hooks, proxy, array storage, splice, or splicing; describe only public method calls and their observable results.
