What is browser-sync?
Browser-sync is a powerful tool for web developers that provides live reloading, synchronized browser testing, and other features to streamline the development process. It helps in creating a seamless development experience by automatically refreshing the browser whenever files are changed, and it can also synchronize interactions across multiple devices.
What are browser-sync's main functionalities?
Live Reloading
This feature allows the browser to automatically reload whenever files in the specified directory are changed. The code sample sets up a server to serve files from the 'app' directory and watches for changes in any files within that directory, triggering a reload when changes are detected.
const browserSync = require('browser-sync').create();
browserSync.init({
server: './app'
});
browserSync.watch('app/**/*.*').on('change', browserSync.reload);
Synchronized Browsing
Synchronized browsing ensures that interactions like clicks and scrolls are mirrored across all connected devices. The code sample initializes Browser-sync with ghost mode enabled for clicks and scrolls, allowing these interactions to be synchronized.
const browserSync = require('browser-sync').create();
browserSync.init({
server: './app',
ghostMode: {
clicks: true,
scroll: true
}
});
Proxying an Existing Server
This feature allows Browser-sync to act as a proxy for an existing server, enabling live reloading and synchronized browsing without changing the server configuration. The code sample sets up Browser-sync to proxy requests to 'yourlocal.dev'.
const browserSync = require('browser-sync').create();
browserSync.init({
proxy: 'yourlocal.dev'
});
