Router Question for Node Interview challenge

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"

You should attempt to complete this challenge without looking at any other resources such as googling, stack-overflow, documentation or course materials. However, you may look at any of the files in the project including the schema in the models.js file and the integration tests in test/server.test.js and you may ask the interviewer clarifying questions at any point.

3 Lifelines

• If you get stuck, you have 3 lifelines (like "Who Wants to Be a Millionaire")
  • 1. Online documentation - browse Express, Mongoose, Chai, Chai-Http docs
  • 2. Interview Hint - Ask the interviewer for a hint
  • 3. Google search - one time google search including stack-overflow and docs

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.

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.
