How to launch the app?

• Docker
• Easy way
• Manual

Docker

Not ready for production (front use webpack-dev-server). IMPORTANT: build and launch apps but API and socket connection is unstable (only occurred in containers)

# in root folder
docker-compose up

Easy way:

# in root folder
npm start

The command executes:

• Run redis with docker.
• Install dependencies on root, back and front.
• Run front and back test.
• Launch with pm2 Client, API, client coverage, back coverage servers.
• Open in browser client app (2 windows), api docs, client coverage and back coverage if it is supported

To tears down the servers and cache use:

# in root folder
npm run stop

Manual

# in root folder
docker-compose up -d cache
npm install
npm --prefix back install
npm --prefix front install
npm --prefix back test
npm --prefix front test
npm --prefix back run serve:coverage
npm --prefix front run serve:coverage
npm --prefix back start
npm --prefix front run build:dev

How use the app?

• Open in browser (2 windows) http://<HOST>:9000.
• See the home page.
• Select a house and click on the detail button.
• To return to the home page click on back button of the browser.

See users viewing a property in real time

• Open in browser (2 windows or more for many users) http://<HOST>:9000.
• Select the same property in each window
• See the notification on page.
• Close tab or return to home page.

IMPORTANT

• Every time you see the house detail you are considered a new user (because the app is without authentication)
• If you open http://<HOST>:9000/detail/<ID> does not work because the app is rendered in client.

Development approach

• Application developed in "monorepo style"
• developed with TDD approach, to pass tests while developing use the command npm run tdd inside each project
• The unit tests are located on the same route of source file with extension *.spec.js
• The e2e tests are located in the__tests__ folder.
• Include commit style validation with commitlint standard
• Include code style with eslint
• Include Automatic code format with prettier-eslint
• Include Automatic changelog creation npm run changelog

Development context

Important development decisions are in the README.md in each project folder (back and front).
