Documentation: https://cerces.dev/

Cerces is a type-safe, modern, and intuitive web framework built on Web Standards and OpenAPI, designed with a developer-first approach to streamline API development across various JavaScript runtimes and deployment platforms.

Features

• 👨‍💻 Developer-first and intuitive. Designed for ease of use, enabling rapid development with a focus on developer experience.
• ⚙️ OpenAPI and Zod integrated seamlessly. Built-in integration of Zod validators and OpenAPI schema generators.
• 🏷️ Type-safe routes and parameters. All parameters and schemas are typed when implementing route handlers.
• 📖 Interactive API documentation. Swagger and Redoc pages are available by default at /docs and /redoc.
• 🪝 Dependency injection mechanism. Prepare variables, enforce authentication, and run other tasks before processing a request.

? Which template do you want to use?
❯ bun
cf-workers
aws-lambda

Once dependencies are installed, start the development server:

bun dev

Example

Below is a simple example demonstrating how to create a GET endpoint with path and query parameters using Cerces and Zod for validation, along with the interactive API documentation.

import { App, Path, Query } from "cerces"
import { z } from "zod"

const app = new App({})

app.get("/items/{itemId}", {
    parameters: {
        itemId: Path(z.number().int().min(0)),
        q: Query(z.string().optional()),
    },
    handle: ({ itemId, q }) => {
        return { itemId, q }
    },
})

export default app
