Mobile Club: URL shortener test

❗️ We do not want you to spend more than 3 hours on this test. Please turn in your test even if it is not functional.

Requirements

• node (version 16 and up)
• yarn
• docker
• docker-compose
• SQL client supporting PostgreSQL (PgAdmin, DBeaver, TablePlus...)

Stack

• PostgreSQL
• NestJS
• GraphQL
• Apollo
• GraphQL codegen
• React
• Jest
• Cypress

Getting started

📘 There is no production build configuration (not required for the scope of this test)

Install and start the application:

yarn # install dependencies
yarn dev # run dev. environment

NestJS & React & GraphQL codegen are hot reloaded.

• front-end accessible at: http://localhost:3000
• back-end accessible at: http://localhost:4000
• PostgreSQL accessible at: mobile-club:mobile-club@localhost:5432/url-shortener

To stop the application:

yarn stop

❗️ If you choose to add dependencies be sure to re-build the corresponding docker image. Because node_modules are baked into the image. To do so: yarn rebuild

Test launch commands are available in package.json files, in front-end and back-end subdirectories.

User stories

• As an end user, I want to generate shorter URLs that redirects to the same location, so when I share a link it appears shorter.
• (Bonus): Implement any feature that you like. Few examples to get your imagination started: usage count, expiration date, authentication, user agent tracking.

Submitting your test

• Upload the project on a public repository (Github, Gitlab, BitBucket...)
• Send the link of the project by email to tech@mobile.club

🍀 Best of luck, from Mobile Club’s tech team.
