library0.0.106jsnpmunverified

Rajt (v0.0.106, pre-1.0) is a TypeScript-native, fully typed serverless framework (not a runtime) that acts as a bundler layer for AWS Lambda (Node.js ≥18, LLRT) and Cloudflare Workers. It provides a router, middleware, and type-safe request/response handling with zero external runtime dependencies. Its key differentiators: single interface across Lambda and Workers, tree-shakable bundler integration, and strict typing that catches misconfigurations at compile time. Active development with frequent releases; not stable yet. Consider alternatives like @aws-lambda-powertools, Hono, or Itty Router for production.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Rajt

✓ import { Rajt } from 'rajt'

✗ const Rajt = require('rajt')

Rajt is ESM-only; CJS require() throws. Named export, not default.

Router

✓ import { Router } from 'rajt'

✗ import Router from 'rajt'

Router is a named export, not default. Common mistake due to other frameworks.

defineConfig

✓ import { defineConfig } from 'rajt'

✗ import { defineConfig } from 'rajt/config'

Subpath exports not defined; 'rajt' only.

Creates a basic HTTP server using Rajt's router and exports the handler for AWS Lambda or Cloudflare Workers.

import { Rajt, Router } from 'rajt'; const router = new Router(); router.get('/hello', async (req) => { return new Response('Hello, World!'); }); const app = new Rajt(); app.use(router); export const handler = app.handle;

Debug

Known issues

breakingRajt v0.0.106 is pre-1.0 with frequent breaking changes. API surface may change without major version bump.

fix

Lock version and watch changelog. Do not use for production-critical applications.

affects: <1.0.0

gotchaThe Router instance does not support middleware attached directly to it; must use Rajt instance's use() method.

fix

Call app.use(router) instead of router.use(middleware).

affects: >=0.0.0

gotchaEnvironment-specific features (e.g., AWS Lambda context) require explicit types from 'rajt/types/aws' or 'rajt/types/cloudflare'.

fix

Import types: import { LambdaContext } from 'rajt/types/aws';

affects: >=0.0.0

breakingLLRT support is experimental and may not cover full Lambda API.

fix

Test thoroughly on LLRT; file issues if missing features.

affects: >=0.0.0

gotchaResponse objects must follow Web API Response interface; do not use AWS Lambda-style callbacks.

fix

Return a standard Response object, e.g., new Response(body, { status: 200 }).

affects: >=0.0.0

Errors

Common errors & fixes

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'rajt' imported from ...

ESM-only package; using require() or misconfigured bundler/Node.js ES modules.

fix

Ensure package.json has 'type': 'module' and use import syntax. Node.js >=18 required.

TypeError: (intermediate value).use is not a function

Calling router.use() instead of app.use(router).

fix

Use app.use(router) on the Rajt instance.

TS2339: Property 'requestContext' does not exist on type 'Request'

Accessing Lambda-specific properties without type augmentation.

fix

Import and use types from 'rajt/types/aws' as type assertion.

SyntaxError: Unexpected identifier 'Rajt'

Importing rajt using CJS require() or in a CJS context.

fix

Switch to ESM syntax: import { Rajt } from 'rajt'.
