fastify-loader

The route loader for the cool kids!

Do you also want an easy way to load routes for fastify? YEAH me too! This is why I made this module.

fastify-loader makes it easy to load routes from a directory.

Features

• Looks cool
• No need to module.export = (fastify) => { /* your code here */ }
• No need to export the fastify instance itself
• No module.export = { path: '/api/test', handler: (req, reply) => {} }

Please, give me an example!

// File: ./api/hello.js
 
// YES, really! You don't need to require anything here. 
// The fastify instance gets injected in any file matched by the glob.
fastify.get('/api/hello', async () => {
    // Complex code here
    return { hello: true };
})

// File: ./server.js
 
const fastify = require('fastify')();
 
// Just register the plugin and add glob array which files to loud
fastify.register(require('fastify-loader'), {
    paths: ['./api/**/*.js'], // A glob array
    name: "fastify" // [Optional] if you want to do something like this: YOURNAMEHERE.get('/api/test')
});
 
fastify.listen(1337, err => {
    if (err) console.trace(err);
    console.log('http://127.0.0.1:1337');
});

Installation

Like any other npm module.

yarn add fastify-loader
# or with npm 
npm i fastify-loader --save

How does this work?

It uses vm2 to inject the fastify instance and other vars into the scope of each file.

WebStorm/{INSERT OTHER IDE HERE} says that fastify is an unknown variable. What can I do?

If your IDE supports JSDoc, you can append this to the file.

// File: ./api/hello.js
+ /**
+  * @var {fastify.FastifyInstance} fastify
+  */
 
// noinspection ES6ModulesDependencies
fastify.get('/api/hello', async () => {
    // Complex code here
    return { hello: true };
})

Or better if your IDE supports typescript typings, because then you can do this:

// File: ./api/hello.js
+ /// <reference types="fastify"/>
+ /// <reference types="fastify-loader"/>
 
// noinspection ES6ModulesDependencies
fastify.get('/api/hello', async () => {
    // Complex code here
    return { hello: true };
})

Do tests exist?

Yes. You can run yarn test or npm run test after you installed the dependencies.

Inject more than just fastify

fastify.register(require('fastify-loader'), {
    paths: ['./api/**/*.js'], // A glob array
    inject: {
        pi: 3.14 // pi is now available as var in each js file in ./api
    }
});
