Tesonet FrontEnd developer task

Basic instructions

Fork this repo
Grab design files from here.
If you don't have Sketch or Photoshop, there are always free options to preview design:
- Avocode - just import .sketch file
- Zeplin - just import .sketch file
- Figma - just import .sketch file
Do your best with the task 💪
Prepare a pull request and let us know that you are done (feel free to add comment a about the task)

Design should be recreated as per provided design file. We aren't talking about pixel perfect, we know there are gazillion screen sizes these days, just follow best UI/UX patterns, don't invent new icons, colors or spacing and you're all good! 👍
Design must be mobile-firendly and responsive.
Use SVG's where possible
For CSS you can use whatever you need and feel comfortable with (vanilla CSS is an option too), but we strongly recommend these:
- pre-processor (SCSS)
- CSS-in-JS library (styled-components, JSS, emotion, aphrodite)
- BEM methodology

Use ES6+ features where applicable
Use react.js
Use state management solution (redux preferably). We know it is possible to do without, but we are curious - can you do with?
This must be a single page application. Use routing library(react-router-dom or @reach/router)
Implement login by sending an authorization request (POST) to https://playground.tesonet.lt/v1/tokens to generate a token (don't forget to pass Content-Type):

{ "username": "tesonet", "password": "partyanimal" }

Use browser storage solution to persist token between sessions
Use the token to retrieve the server list from https://playground.tesonet.lt/v1/servers,
Order the results of servers list by distance and name.
Implement logout (don't forget about the token in the storage)
Your app must work on all modern browsers and IE11+ 🐢🤷

It is all good to use create-react-app as a starter, but if you have time and want showcase your skill - use JS bundler (Webpack preferred) 📦📦📦
We highly recommend following TDD patterns and showcasing your skills at writing tests(unit, integration, e2e - all are good)
Use npm scripts for running tasks, i.e. for development, clening build or etc.
Do validation of login fields and provide user friendly error messages if needed #UXmatters
Indicate loading state for the user whenever requests are in action and user might not understand they needs to wait
