Cloudflare Worker Rest Api

This library helps build serverless rest api with cloudflare workers

Description

The idea behind this package was to create a library that would be as close to express framework as possible, and that would make creating Rest Apis with Workers quick and easy.

Installing

Begin by installing the package with npm.

npm install cloudflare-worker-rest-api --save 

Example App

For a fully working example check out this project

How to use

Import the package and initialize your app.

const restCfWorker = require("cloudflare-worker-rest-api")
const app = new restCfWorker()

// ....

addEventListener('fetch', event => {
  event.respondWith(app.handleRequest(event.request))
})

In order for cloudflare to use your app, we need to call app.handleRequest on the fetch event listener.

Rest API

The supported methods are POST, GET, DELETE, PATCH, PUT and ANY.

// supports middlewares
app.use((req, res) => {
    // do some authenticate process
    req.isAuthenticated = true
})

app.get("/path-here", (req, res) => {
    // access query 
    const { filter, page } = req.query()

    return res.send({ status: 1, message: "Hello stranger!" })
})

app.post("/path-here", async (req, res) => {
    // access body
    const { username } = await req.body()

    if (!req.isAuthenticated) {
        // supports status code
        return res.send({ status: 1, message: "Bro, you not supposed to be here!" }, 401)
    }
    return res.send({ status: 1, message: "Hello stranger, why are you still here!" })
})

// supports path params
app.delete("/item/:itemId", (req, res) => {
    const { itemId } = req.params

    return res.send({ status: 1, message: `Oh no, you deleted item ${itemId}` })
})

Routing

The package also supports routers, if you want to divide your code in multiple files.

// ./routers/auth.js
const restCfWorker = require('cloudflare-worker-rest-api')

const router = new restCfWorker()

router.post('/login', (req, res) => {
    return res.send({ status: 1, message: "Successfully logged in!" })
})

// export the router
module.exports = router 

Then you can call your router file in your index file

const restCfWorker = require("cloudflare-worker-rest-api")
const authRouter = require("./routers/auth.js")

const app = new restCfWorker()

// use router
app.use("/auth", authRouter)

addEventListener('fetch', event => {
  event.respondWith(app.handleRequest(event.request))
})

The login route now would be POST /auth/login
