Project setup

1. Copy the source/ directory into your project root, e.g. vendor/redwood/.

2. Add path aliases to tsconfig.json:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@rwapi/*": ["vendor/redwood/api/src/*"]
    },
    "module": "CommonJS",
    "target": "ES2020",
    "esModuleInterop": true,
    "resolveJsonModule": true
  }
}

3. Set environment variables needed at runtime:

NODE_ENV=production          # controls logger pretty-printing
REDWOOD_ENV_PREFIX=          # optional prefix for env injection

4. Import directly from the api/src entry point or sub-paths:

import { createLogger, parseAuthorizationHeader, createVerifier } from './vendor/redwood/api/src'

5. The package reads its own package.json for version exports. Ensure the file exists at vendor/redwood/api/package.json with at minimum a version and dependencies["@prisma/client"] field.

Public API

AUTH_PROVIDER_HEADER

export const AUTH_PROVIDER_HEADER: 'auth-provider'

The canonical header name used to identify which auth provider signed a request. Use this constant instead of a magic string when reading the header in middleware or tests.

getAuthProviderHeader

export const getAuthProviderHeader = (
  event: APIGatewayProxyEvent | Request,
): string | undefined

Extracts the auth-provider header value from either a Lambda proxy event or a standard Web API Request. Use this in custom auth middleware to branch on provider type (e.g., "dbAuth", "supabase").

parseAuthorizationCookie

export type AuthorizationCookies = {
  parsedCookie: Record<string, string | undefined>
  rawCookie: string
  type: string | undefined
} | null

export const parseAuthorizationCookie = (
  event: APIGatewayProxyEvent | Request,
): AuthorizationCookies

Parses the Cookie header and extracts the auth provider type embedded inside it. Returns null for unauthenticated requests. Use in cookie-based session auth flows where the JWT is stored in a cookie rather than the Authorization header.

createVerifier

export const createVerifier = (
  type: SupportedVerifierTypes,
  options?: VerifyOptions,
): WebhookVerifier

Factory that returns a WebhookVerifier instance for the specified signature scheme. Supported types include sha256Verifier, sha1Verifier, base64Sha256Verifier, jwtVerifier, and secretKeyVerifier. Use this to verify inbound webhook payloads from third-party services.

formatCacheKey

export const formatCacheKey = (key: CacheKey, prefix?: string): string

Normalizes a string | string[] cache key into a single string, optionally prepending a namespace prefix separated by -. Use before passing keys to any cache client to avoid collision across models or services.

Working examples

Scenario - Verify an incoming GitHub webhook

Your Express route receives a POST from GitHub. Verify the X-Hub-Signature-256 header before processing.

import { createVerifier } from './vendor/redwood/api/src/auth/verifiers'

const verifier = createVerifier('sha256Verifier', {
  signatureHeader: 'X-Hub-Signature-256',
})

app.post('/webhooks/github', async (req, res) => {
  try {
    const body = await req.text()
    const isValid = verifier.verify({
      body,
      signature: req.headers['x-hub-signature-256'] as string,
      secret: process.env.GITHUB_WEBHOOK_SECRET!,
    })
    if (!isValid) return res.status(401).send('Bad signature')
    // process payload
    res.sendStatus(200)
  } catch (e) {
    res.status(400).send((e as Error).message)
  }
})

Scenario - Extract auth provider from a fetch Request

In an edge middleware that receives a Request object, determine which auth provider the client is using.

import {
  getAuthProviderHeader,
  parseAuthorizationCookie,
} from './vendor/redwood/api/src/auth'

export async function middleware(request: Request): Promise<Response> {
  const provider = getAuthProviderHeader(request)

  if (!provider) {
    // fall back to cookie-based auth
    const cookieAuth = parseAuthorizationCookie(request)
    if (!cookieAuth) {
      return new Response('Unauthorized', { status: 401 })
    }
    console.log('Auth via cookie, type:', cookieAuth.type)
  } else {
    console.log('Auth via header, provider:', provider)
  }

  return new Response('OK')
}

Scenario - Cache a Prisma query result with Redis

Wrap an expensive findMany call with a Redis-backed cache using the cache utilities.

import { RedisClient, formatCacheKey } from './vendor/redwood/api/src/cache'
import { createLogger } from './vendor/redwood/api/src/logger'

const logger = createLogger({ name: 'cache-example' })
const redis = new RedisClient(redisConnection, { logger })

async function getProducts(categoryId: number) {
  const key = formatCacheKey(['products', String(categoryId)], 'shop')
  // key => "shop-products-42"

  const cached = await redis.get(key)
  if (cached) return JSON.parse(cached)

  const products = await db.product.findMany({ where: { categoryId } })
  await redis.set(key, JSON.stringify(products), { expires: 300 })
  return products
}

File walkthrough

• api/src/index.ts - Main barrel export; re-exports auth, errors, validations, transforms, CORS, event utilities, and version constants.
• api/src/auth/index.ts - Auth header/cookie parsing utilities and shared constants like AUTH_PROVIDER_HEADER.
• api/src/auth/verifiers/ - Individual webhook signature verifiers (SHA1, SHA256, Base64, JWT, secret key) plus the createVerifier factory.
• api/src/cache/ - Caching abstraction with MemcachedClient, RedisClient, InMemoryClient, key formatting helpers, and timeout error types.
• api/src/logger/index.ts - Pino-based structured logger with Prisma-compatible log level types and environment detection helpers.
• api/src/validations/ - Input validation helpers for service functions.
• api/src/webhooks/ - Higher-level webhook processing helpers built on top of verifiers.
• api/src/cors.ts - CORS header construction utilities.
• api/src/errors.ts - Typed error classes for use across the API layer.
• api/src/event.ts - Normalizes Lambda proxy events and Web Request objects into a unified interface.
• api/src/transforms.ts - Request/response body transformation helpers.
• api/src/types.ts - Shared TypeScript types across the API package.

Common pitfalls and fixes

• require('../package.json') fails at runtime - Ensure vendor/redwood/api/package.json exists and resolveJsonModule: true is set in tsconfig.json.
• aws-lambda types missing - Install @types/aws-lambda as a dev dependency; it is a pure type package not included by default.
• Pino outputs JSON in development and breaks readability - Set NODE_ENV=development and use pino-pretty as a transport: pino({ transport: { target: 'pino-pretty' } }).
• Cache key collisions across environments - Always pass a prefix to formatCacheKey that includes the environment (e.g., prod-users vs staging-users).
• cookie package ESM/CJS mismatch - Pin cookie to ^0.6.0 and ensure your bundler is configured with esModuleInterop: true; v1.x changed the export shape.
• createVerifier throws for unknown type - The type argument must exactly match a key in verifierLookup; check api/src/auth/verifiers/common.ts for the exhaustive list before passing dynamic strings.

Vibe-coding prompt template

I have the RedwoodJS API package source code in `vendor/redwood/` and a usage guide
at `USAGE.md`. I am building a Node.js/TypeScript Express application.

Please help me integrate the following capabilities step-by-step:

1. Set up the logger from `vendor/redwood/api/src/logger` as the global logger for
   my Express app, with Prisma query logging enabled.
2. Add webhook signature verification to my `/webhooks` route using `createVerifier`
   from `vendor/redwood/api/src/auth/verifiers`.
3. Add cookie-based auth provider detection middleware using `parseAuthorizationCookie`
   and `getAuthProviderHeader` from `vendor/redwood/api/src/auth`.
4. Wire up the Redis cache client from `vendor/redwood/api/src/cache` for caching
   database queries, using `formatCacheKey` for all keys.

For each step: show the exact import paths relative to my project root, the code to
add, and any environment variables required. Reference `USAGE.md` for type signatures
and constraints. Do not invent exports that are not documented there.
