Like any kind of apps, JavaScript apps also have to be written well.

Otherwise, we run into all kinds of issues later on.

In this article, we’ll look at some best practices we should follow when writing React apps.

Keep Components Small and Specific

Components should only do one thing.

This way, we can test and maintain them easier.

Each small component can be reused across projects.

The components can be made available to the community.

We can implement performance optimizations on smaller components more easily,

Bigger components have to do more and it’s harder to maintain.

Reusability

We should create components that are reusable so that we don’t have to add new ones all the time.

They can be used across any number of projects.

If a component becomes big, we can break them up to smaller components.

For instance, we can write:

const Button = ({ iconClass, onClick }) => {
  return (
    <button onClick={onClick()}>
      <i class={iconClass} />
    </button>
  );
};

to make a reusable button.

It takes the iconClass and onClick props so that we can pass click handlers and icon class to them.

If we have duplicate code, we should consolidate them into one.

This way, we can just use one icon to do everything.

Put CSS in JavaScript

We can put CSS into our JavaScript code.

If a project is created with Create React App, we can import CSS files as modules.

This is because Webpack has the CSS loader added to it to let us do that.
