The Rules of React

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

Cloning into 'my-awesome-proj'...
ssh: connect to host github.com port 22: Connection timed out
fatal: Could not read from remote repository.
$ # This should also timeout
$ ssh -T [email protected]

testing library concept and basic test

You first need to undestand the concept of frontend tests.

You should not test the implementation but the behavior

You test like the end user

For instance, imagine a login screen with email and password inputs and a submit button

The test should input the email and the password, then click in the submit button.
