Adding routes and other essential middleware

We established the integration and structured the server-side directory in the previous section. Now let's refine some API routes and other middleware on our API in the following steps:

1. Install the Koa Router and Koa Static packages via npm:

$ npm i koa-route

2. Create a server-side config file:

// server/config/index.js
export default {
  static_dir: {
    root: '../static'
  }
}

3. Create a routes.js file in the /server/ directory for defining routes that we will expose to the public with some dummy user data:

// server/routes.js
import Router from 'koa-router'
const router = new Router({ prefix: '/api' })

const users = [
  { id: 1, name: 'Alexandre' },
  { id: 2, name: 'Pooya' },
  { id: 3, name: 'Sébastien' }
]

router.get('/', async (ctx, next) => {
  ctx.type = 'json'
  ctx.body = {
    message: 'Hello World!'
  }
})
