3. Routing

End goal structure

The end goal of the exercise is to implement the following routes:

• GET /api/snippets to get a list of snippets

• GET /api/snippets/:id to get a single snippet

Create Snippets router

We will create the snippet routes in a different file, api/snippets.js, which will export an Express router.

That will look something like this:

// Contents of api/snippets.js

import express from "express";
const router = express.Router();

// GET /api/snippets
router.get("/", async (request, response) => {
  // TODO
  console.log("Hello from Snippets");
});

// TODO: GET /api/snippets/:id

export default router;

Add the router to the main server

Next thing in the setup is to actually use the router we're exporting from api/snippets.js. Inside app.js, below setting up Express, add your new snippets router:

import snippetsRouter from "./api/snippets.js";

app.use("/api/snippets", snippetsRouter);

Test the app

Run the main app. Does you console log Hello from Snippets on http://localhost:3000/api/snippets?

End file structure

At this point verify that your project structure looks like this:

• api

  • snippets.js

• app.js

• package.json
