Prefresh-webpack

Setup

npm i -s @prefresh/webpack
## OR
yarn add @prefresh/webpack

Then add it to your webpack config by doing

import PreactRefreshPlugin from '@prefresh/webpack';

const config = {
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new PreactRefreshPlugin(),
  ],
  devServer: {
    hot: true, // ensure dev-server.hot is on
    ...moreDevServerConfig,
  },
  ...moreWebpackConfig,
};

Using hooks

If you're using preact/hooks you'll need something extra to ensure we can handle changes in hooks well.

You'll need to add @prefresh/babel-plugin to your babel-configuration to make this work together.

Best practices

Recognition

We need to be able to recognise your components, this means that components should start with a capital letter and hook should start with use followed by a capital letter. This allows the Babel plugin to effectively recognise these.

Do note that a component as seen below is not named.

export default () => {
  return <p>Want to refresh</p>;
};

Instead do:

const Refresh = () => {
  return <p>Want to refresh</p>;
};

export default Refresh;

When you are working with HOC's be sure to lift up the displayName so we can recognise it as a component.
