Assumptions about the runtime env

• Node version > 12. I have tested on version 12 but is suppose to run on v10 and later.
• My local environments are Linux/MacOsX but it should run on WIN10 environment as well.

Installing and running locally

To run locally on port 3000 (http://localhost:3000) use the following command after entering project's directory.

./install_build.sh build && ./run.sh

• The port can be changed in .env file

I have created 2 simple scripts on the main directory install_build.sh & run.sh

install_build.sh

This script can be run with the following arguments:

1. install - Will install Angular & NestJS dependencies which are located in client & server respectively.
2. build - Will build client & server and copy the client/dist/client into server/dist/client folder which holds all the built artifacts (it copies package.json & .env.local into /server/dist directory too to allow simpler running of the project).
3. If no arguments are supplied the script will install and build both of the projects.

run.sh

This script assumes the project already was built and the backend was installed (node_modules).

BackEnd (Server side)

I have chose to use NestJS framework because it seems suitable for this challenge and it's written in typescript which makes it very easy to work with angular cli

• The Database I chose for this project is sqlite3 because it's very portable and doesn't require running separate database process. I'm using knex to run sql queries with promise wrapper and it's very simple to configure knex to work with other DB's (MySql, PGSql,MSSql...) without requiring major code refactoring.
• User passwords are encrypted when storing in DB.
• I use .env (dotenv) package to supplies external process variable (Port, DB file location, token expiration time, JWT secret). This allows easy expansion of the app later on.

Frontend (Client side)

• FrontEnd is written with latest angular CLI version.
• I chose to use bootstrap 4 and ng-bootstrap.
• The Users are displayed on /home route.
• When user is logged-in he will be able to logout by clicking on the red top right corner button.
• Navigation to /profile rote is protected and requires the user to be logged in.
• User will be automatically logged out and redirected to login/register page when the JWT expires.
• JWT is stored in localStorage with minimum user credentials.
• When clicking on user card a simple modal is displayed and shows the selected user details without the password for obivious reasons.

Troubleshooting

Build issues

If there are installation errors encountered during sqlite3 installation building sqlite3 from source should fix them: npm install --build-from-source

Running scripts issues On win10 there might be issues running the script because windows doesn't support running bash/shell scripts natively but if git bash installed it should work fine. The alternative is to build & run everything manually.
