SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates hours of trial and error when building Elysia.js (Bun) APIs with TypeScript, resolving common compilation errors, runtime 500s, and validation failures caused by framework-specific type system and routing quirks.

Core Features & Use Cases

  • Route Parameter Conflict Fixes: Resolves errors from conflicting path parameter names in Elysia's memoirist router.
  • Context Typing Workarounds: Fixes missing property errors on route handler context from auth middleware derive calls.
  • Schema & Plugin Error Resolution: Addresses recursive schema type inference issues, JWT plugin misuse, optional field null validation errors, and nginx proxy interoperability problems.
  • Use Case: A backend developer building a production Elysia API can use this Skill to quickly fix intermittent 500 errors from broken derive hooks or 422 validation errors from optional null fields without debugging framework internals.

Quick Start

Apply the relevant workaround from this skill to fix the TypeScript or runtime error you are encountering while building your Elysia.js (Bun) API.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix missing property errors on Elysia.js route handler context from derive middleware?

Fix missing property errors on Elysia.js route handler context by applying context typing workarounds that resolve derive hook type propagation failures, ensuring auth middleware data is correctly typed across routes.

Why does my Elysia.js API return a 500 error when using JWT plugin authentication?

Elysia.js APIs returning 500 errors during JWT plugin usage are often caused by plugin misuse; applying the correct JWT plugin initialization and token verification patterns resolves these runtime failures.

How do I resolve route parameter naming conflicts in Elysia.js memoirist router?

Resolve route parameter naming conflicts in Elysia.js by renaming duplicate path parameters in your route definitions, which fixes compilation errors originating from the memoirist router's parameter handling limitations.

How do I fix 422 validation errors for optional null fields in Elysia.js schemas?

Fix 422 validation errors for optional null fields in Elysia.js by adjusting your schema validation definitions to handle null values explicitly, addressing recursive schema type inference issues.

Does Elysia.js work behind an nginx reverse proxy without losing request data?

Elysia.js works behind an nginx reverse proxy, but requires specific interoperability configurations to prevent header or body loss, ensuring reliable API deployment in production environments.

What causes recursive schema type inference errors in Elysia.js TypeScript APIs?

Recursive schema type inference errors in Elysia.js TypeScript APIs are caused by complex nested schema definitions; flattening the schema structure or applying specific type annotations resolves these compilation failures.
