What its author says it does

Copied from the file, not written here

Build, review, debug, test, migrate, secure, or deploy Elysia and ElysiaJS applications with current documentation. Use for Bun or Node Elysia servers, routes, schemas and validation, lifecycle hooks, plugins and scope, guards, macros, context extension, error handling, Eden Treaty, OpenAPI, WebSocket, SSE, runtime adapters, and production readiness.

Elysia

Use this skill when the work touches Elysia or ElysiaJS.

Workflow

  1. Inspect the application before proposing changes:
    • Installed versions of elysia and relevant @elysia/* packages.
    • Runtime and adapter: Bun, @elysia/node, Deno, Cloudflare Worker, Vercel, Netlify, or another Web Standard host.
    • Root instance, export/listen shape, route plugins, prefixes, guards, macros, schemas, error hooks, and tests.
    • Registration order and plugin scope for every cross-cutting hook.
  2. Refresh current official docs when the task depends on latest APIs, adapters, package compatibility, experimental support, or version-specific behavior. Start from source-map.md.
  3. Route the work to the focused references:
  4. Preserve the repository's existing architecture and commands unless the user explicitly asks for a migration.
  5. Verify behavior at the narrowest useful boundary, then verify the assembled application.

Core Judgment

  • Treat schemas as executable HTTP contracts. Define request and per-status response schemas where the boundary matters; do not duplicate them with hand-written interfaces.
  • Keep route handlers thin. Prefer feature-scoped Elysia instances for HTTP concerns and ordinary functions/modules for business logic that does not need request context.
  • Let Elysia infer handler context. Do not pass a broad manually typed Context through controllers or services when destructured values or schema-derived types are sufficient.
  • Respect chain order. Interceptor hooks apply to routes and plugins registered after them, except onRequest, which is global to incoming requests.
  • Respect plugin encapsulation. A plugin's lifecycle hooks and schemas do not automatically protect parent routes. Choose local, scoped, or global deliberately and test the boundary.
  • Prefer resolve over derive when a value depends on validated request data. derive runs before validation; resolve runs after validation.
  • Return status(code, value) for expected HTTP outcomes when type-safe response narrowing matters. Throw only when the outcome should pass through onError.
  • Use named plugins, plus seed when configuration changes identity, when lifecycle deduplication matters.
  • Treat OpenAPI security declarations as documentation only. Enforce authentication and authorization in guards, macros, hooks, or handlers.
  • Do not assume Bun-only APIs on other adapters. server and server.requestIP are Bun-specific; adapter and platform limitations must shape the implementation.
  • Do not quote benchmark numbers as general application performance guarantees. Profile the actual app and runtime.

Verification

Prefer repository-owned commands. For meaningful Elysia changes, cover the relevant subset:

  • Typecheck and production build with the actual runtime/adapter.
  • Direct app.handle(new Request('http://localhost/...')) tests for success, validation failures, auth failures, error mapping, headers, and status-specific response bodies.
  • Scope/order regression tests when changing hooks, guards, macros, or plugin composition.
  • await app.modules before testing deferred or lazy-loaded plugins.
  • Eden contract tests when the application exports its type to clients.
  • Generated OpenAPI inspection when schemas, response status maps, tags, security metadata, or type generation changes.
  • Real HTTP smoke test for listen/export, proxy headers, cookies, CORS preflight, streaming, and runtime-specific behavior.
  • WebSocket connection, invalid-message, close, timeout, and backpressure checks when realtime behavior changes.
  • Deployment-target smoke test when changing adapters, bundling, binary compilation, serverless exports, environment variables, or platform bindings.

Report which checks ran, which did not, and any version-sensitive assumptions that remain.
