Router Question for Node Interview challenge

Primary LanguageJavaScript

Live coding practice interview question

Overview

This is a FullStack Todo Application, the client is based on Todo MVC

  • Stack:
    • Client: Basic jQuery selectors, event-handlers, DOM manipulation and AJAX
    • Web Server: Node and Express with PostgreSQL
    • Database: Locally hosted PostgreSQL
    • Tests: Supertest, Chai

The Rules

As in previous interviews, you may consult official docs and reference-style resources during this coding challenge. You are encouraged to work through as much of it on your own as you can.

Setup

  • Clone this repository to your local machine
  • Install the dependencies for the project
  • Ensure your PostgreSQL server is running
  • Create a User for this exercise
  • Create a database for the exercise with your user as the owner
  • Rename the example.env file to .env and update the following fields with your database credentials: 
     MIGRATION_DB_NAME=
 MIGRATION_DB_USER=
 MIGRATION_DB_PASS=
 DB_URL="postgresql://USERNAME@localhost/DATABASE_NAME"
  • Run the command npm run migrate -- 1 to create the database tables
  • run the command npm t
  • You should see output from 10 integration tests, all will be passing.

NOTE: Due to some deployment requirements you will need to use Postgres version 8 if you are using Node 14. Use Postgres version 7 if you are using Node 12. To change your version of Node you can use nvm.

If you decide to use Node 12 and Postgres 7 you will need to set ssl: process.env.NODE_ENV === "production" in postgrator-config and pg.defaults.ssl = process.env.NODE_ENV === "production" in server.js

Exercise

  • Todo Router
    • Create a new file name todo-router.js in the todo directory
    • Move all the endpoints from app.js to todo-router.js
    • Require the proper modules into todo-router.js and export the router
    • In app.js, mount the router on /v1/todos/ path (aka mount point)
    • Remember to update the paths on the router files.

You have completed the task when all the unit tests pass and the client application works without any errors.
