Weather app

Live at https://wwweather-sand.vercel.app/

Local setup

1. Clone the repo
2. npm i
3. npm dev will run the app with Vite dev server
4. npm test to run the tests

App structure

Functionality

The app has 2 pages:

• "/" - displays list of locations and their weather
• "/:location" – shows weather details for specified location
• you can add/remove locations, your changes are saved in localstorage

Tech stack

• React, TypeScript
• ESLint / Prettier
• Vite blazing fast build system
• react-query - to cache server state and have handy fetch hooks
• react-router v6
• Vitest unit-test framework
• React testing library
• Mock service worker – use it for integration tests with vitest and RTL.
• Deployed with Vercel

Folder structure and naming

• Use screaming architecture pattern as opposed to putting all the similar things by type into one folder.
• Colocate things as much as possible. If something is not used outside the feature, there is no point to have it outside the feature-folder. Exceptions are possible though.
• Use kebab-case for file/folder names. Why?

Potential improvements

Well, functionality and design could be way better, that goes without saying.

Just a few tech related things below.

Approach to testing

You can always write more tests 🙃

Mostly, I write unit tests for utility functions or small presentational components without too many dependencies. In this project I didn't bother with that as both pages of the app covered pretty well with the integration tests.

Approach to styling

I didn't use any particular thing here (only the slightest hint of BEM) as the project is quite small and regular CSS does the job here. For a real project I would probably prefer tailwind.
