PROJECT PHASE 2 (EXPRESS ROUTER)

 EXPRESS ROUTERS ARE A WAY TO ORGANIZE YOUR EXPRESS APPLICATIONS SUCH THAT IT DOESNOT BECOME BLOATED. IT IS NOT NECESSARY TO USE EXPRESS ROUTER, BUT IT IS CONSIDERED AS A GOOD PRACTICE.

IT REDUCES THE SIZE OF THE FILE BY CREATING A NEW ROUTE.

HERE WE CREATE A NEW FOLDER CLASSROOM AND A FILE server.js IN IT.HERE WE CREATE SEVERAL ROUTES FOR POSTS AND USERS TO UNDERSTAND BLOATING AND REDUCE IT.

const express = require("express");

const app = express();

// HOME ROUTE-POSTS

app.get("/", (req, res) => {

  res.send("I am root!");

});

// POSTS ROUTE

app.get("/posts", (req, res) => {

  res.send("GET FOR POSTS");

});

// POSTS id  ROUTE

app.get("/posts/:id", (req, res) => {

  res.send("GET FOR POSTS ID");

});

// new POSTS ROUTE

app.post("/posts/new", (req, res) => {

  res.send("POST FOR NEW  POSTS");

});

// DELETE POSTS ROUTE

app.delete("/posts/:id/delete", (req, res) => {

  res.send("DELETE FOR POSTS");

});

// USERS ROUTE

app.get("/users", (req, res) => {

  res.send("GET FOR USERS");

});

// USERSE id  ROUTE

app.get("/users/:id", (req, res) => {

  res.send("GET FOR USERS ID");

});

// new USER ROUTE

app.post("/users/new", (req, res) => {

  res.send("POST FOR NEW  USERS");

});

// DELETE USERS ROUTE

app.delete("/users/:id/delete", (req, res) => {

  res.send("DELETE FOR USERS");

});

app.listen(3000, () => {

  console.log("listening to port 3000");

});

HERE A NEW FOLDER routes IS CREATED. IN WHICH A SEPERATE FILE FOR BOTH POSTS AND USERS ROUTES ARE CREATED AND THEY ARE REQUIRED BY A SINGLE LINE OF CODE.

SERVER.JS

const express = require("express");

const app = express();

const users = require("./routes/users");

const posts = require("./routes/posts");

// HOME ROUTE-POSTS

app.get("/", (req, res) => {

  res.send("I am root!");

});

app.use("/users", users); //IT MEANS THAT ROUTES COMING FROM users START WITH TAG /users

app.use("/posts", posts);

app.listen(3000, () => {

  console.log("listening to port 3000");

});

USERS.JS

const express = require("express");

const router = express.Router();

HERE WE DIDN'T INCLUDE /users IN THE ROUTES AS WE MENTIONED app.use("/users", users);

IN THE SERVER.JS

// users route

router.get("/", (req, res) => {

  res.send("GET for users");

});

// USERSE id  ROUTE

router.get("/:id", (req, res) => {

  res.send("GET FOR USERS ID");

});

// new USER ROUTE

router.post("/new", (req, res) => {

  res.send("POST FOR NEW  USERS");

});

// DELETE USERS ROUTE

router.delete("/:id/delete", (req, res) => {

  res.send("DELETE FOR USERS");

});

module.exports=router;

POSTS.JS

const express = require("express");

const router = express.Router();

HERE WE DIDN'T INCLUDE /posts IN THE ROUTES AS WE MENTIONED app.use("/posts", posts);

IN THE SERVER.JS

// POSTS ROUTE

router.get("/", (req, res) => {

    res.send("GET FOR POSTS");

  });

 

  // POSTS id  ROUTE

  router.get("/:id", (req, res) => {

    res.send("GET FOR POSTS ID");

  });

  // new POSTS ROUTE

  router.post("/new", (req, res) => {

    res.send("POST FOR NEW  POSTS");

  });

  // DELETE POSTS ROUTE

  router.delete("/:id/delete", (req, res) => {

    res.send("DELETE FOR POSTS");

  });

  module.exports=router;
