This is Node Weather

This is a quick test project, to show off Node and server- and client side rendered React running in unison.

It uses:

• Node and Express on the server side
• React as a view engine (client and server side)
• Jest and Enzyme for tests
• WebPack and Babel for bundling

How to use it

1. git clone this repo
2. cd into the directory
3. Install all dependencies by running yarn (presumably npm would also work).
4. Run yarn start to fire up the server
5. Go to http://localhost:3000 to see it in action

Optional step 3a: This project has a .nvmrc file. You can run nvm use to switch to the same Node version (currently set up for latest LTS). You may need to run nvm install.

You can also run yarn test to run the tests, if you so please.

Features

• It should show the weather for Copenhagen as a default – rendered from the server
• Changing the query parameter to city={your city} should show the weather for that city (again, server rendered)
• Using the form to type in a new city, and submitting, will fetch new data and render it on the client side
• Changing the city on the client side will also update the URL, and using the back/forward buttons will also update the view and the data
• Attempting to enter a invalid city will display an error message

Limitations

• There is not 100% test coverage. A select few methods and views are covered.
• API mocking is not covered by testing.
• There is some basic error handling, but not all cases are covered, and there is no distinction between invalid input and a server error, for example.
• We also assume correct input to all helper methods.
• There are also no special error pages (like 404 or 5xx).
• There are no loaders – fast response time is assumed.
