Handlers ​

Every route file will export route handlers, these correspond to http verbs such as GET, POST, PUT, etc. The shape of a route handler varies by framework, all these examples will use express but you can refer to the page on your framework in the Adapters Section.

For example, if we had a file called test.js and wanted a GET, POST, and DELETE method we could do:

// test.js

export const GET = (req, res) => {
    res.send('GET Hello World');
}

export const POST = (req, res) => {
    res.send('POST Hello World');
}

export const DELETE = (req, res) => {
    res.send('DELETE Hello World');
}

ALL Handlers ​

Some frameworks support an ALL handler which will respond to any type of HTTP request. Some adapters only support an ALL handler if it's the only handler in the route file. To check if your framework supports this check it's adapter documentation.

export const ALL = (req, res) => {
    res.send(`${req.method} Hello World`)
}

Type Safety ​

In our previous example, our route handlers aren't type safe. We can easily add a type like this:

/** @type {import('express').RequestHandler} */
export const GET = (req, res) => {
    res.send('Hello World')
}

However to make it easier, all official Neru adapters (and most unofficial!) provide a route function that adds Type Safety:

import { route } from '@nerujs/express';

export const GET = route((req, res) => {
    res.send('Hello World')
})
