My First Web Server

A starter repo for the ACA 311 Express project.

Setup

Initialize and run the app: npm install && npm start.

Testing the routes

Use Postman to test the routes created in the following sections. Your base url will be localhost:4000 (whatever your port number is) and the paths will be the routes defined below. For example, if I wanted to test the users route I would plug in the following information to Postman:

• Protocol: GET
• Request url: http://localhost:4000/users

Part 1: Basic routes

• Create the following routes:

  • GET /users

    • Give your server the ability to respond to a GET request with a path "/users" and return the users array from state.js
    • Ex. res.json(users)

  • GET /users/1

    • Give your server the ability to respond to a GET request with a path "/users/1" and return the first user object from the users array from state.js

  • POST /users

    • Give your server the ability to respond to a POST request with a path "/users" and add a hard coded user object to the users array from state.js. Use res.json() to send the last user in the array (should be the new one) back to the client.
    • If you do another GET request you should see this added
    • You will need to create the hard coded user mentioned above

  • PUT /users/1

    • Give your server the ability to respond to a PUT request with a path "/users/1" and just change any key value (ex. name, occupation) on the first user object in the users array in state.js. Use res.json() to send this user back to the client.

  • DELETE /users/1

    • Give your server the ability to respond to a DELETE request with a path "/users/1" and remove the first item from the users array. Use res.send() to send back a messsage, "deleted"

Part 2. Body-parser module

• Require the body-parser module on the line below require('express'). (it has already been npm installed)

• Give your server the ability to handle a POST request with a path "/users" and add the data from the client to the users array

  • This means you will be adding req.body. Console log this to see what you get and don't forget to send an actual body with the request in Postman

  • Assign an _id property to the user object that is a number that increments by 1 each time.

    • To do this, set a variable called counter near the { users } variable. Start it at the length of the users array

  • Use res.json() to send the user object back to the client. (if you do another GET request you should see this added)

Part 3. Use path variables

• Alter the following routes:

  • GET /users/1 => GET /users/:userId

    • Give your server the ability to respond to a GET request with a path /users/:userId and return the user object from the users array that has the _id == userId

  • PUT /users/1 => PUT /users/:userId

    • Give your server the ability to respond to a PUT request with a path /users/:userId and just change any key value on the user object with this _id

  • DELETE /users/1 => DELETE /users/:userId

    • Give your server the ability to respond to a DELETE request with a path /users/:userId and find the user with this id from the array. Give this user object a new key value isActive: false. Use res.send() to send back a messsage, "deleted"
