This command uses a small Docker container containing PHP and Composer to install the application's dependencies:

In the first terminal window, use the sail up command to start Laravel Sail. This will execute your application within a Docker container and is isolated from your local computer.

./vendor/bin/sail up

In our second terminal, we will use the npm run watch command. The npm run watch command will continue running in your terminal and watch all relevant CSS and JavaScript files for changes. Webpack will automatically recompile your assets when it detects a change to one of these files:

npm install
npm run watch
