todo-router's Introduction

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.
