Socket.IO, fullstack, typescript, Frontend / Backend testing

How to run

yarn # will install pkgs both frontend and backend
yarn test
yarn dev # Backend & frontend

Requirements ✅

The stack should consist of two parts - a front-end client and an API/server.

Client / Front-end

• Should be a ReactJS SPA application.
• You can use Foundation, Bootstrap or any other style framework to help you.
• We expect the application to be fully responsive.
• Should have two main states. An inactive dialler state and an active in-call state.
• A user should be able to dial a number (format irrelevant, think of it as an ID -- these can be auto assigned to the clients).
• If the destination recipient is online/connected, they should receive an incoming call that they can either accept or decline.
• Accepting a call should set up an audio only WebRTC stream between the

Backend

• The backend/server should handle events between clients and act as the “middleman”.
• In terms of event implementation, it’s up to you, but we recommend using sockets.

What We’re Looking For 🔍

We like things that look good but don’t go overboard with the UI design. This is more of a test of your code than your UI design skills.

We’re looking for good code quality. This means readable code, clear, concise logic and good application structure. What makes clean, production-ready code? Think of these things and make sure you try and use them in your solution.

Tests. You don’t need 100% code coverage, but we expect at least one useful front-end and one useful back-end test.
