Description
Live Reload script, mainly designed for usage in programmatic environments like Gulp.
How it works:
It contains 3 entities - LiveReloadServer, FrontClient, BackClient. You start liveReloadServer and BackClient, and include FrontClient script in your html file. Now whenever you change your html/css or bundle new js file, BackClient sends signal to LiveReloadServer, which sends signal to FrontClient in your html page in browser - 'hey, new content available, pls reload'. Then browser automatically reloads, and you see new content, without the need to press F5.
You can detect changes in your html/css/js files via gulp. Also webpack have watch functionality. So you can send liveReload signals when gulp/webpack are finished processing files.
Installation
npm i -D blunt-livereload
Simple gulp example
gulpfile.js
const { listen, makeBackClient, makeLrServer } = require('blunt-livereload');
const gulp = require('gulp');
const { series } = gulp;
const startLrServer = async () => {
const lrServer = makeLrServer();
return listen(lrServer);
};
const backClient = makeBackClient();
const reloadBrowser = async () => backClient.notifyWindowReload();
const paths = {
dest: 'build',
public: { src: 'src/**/*' },
};
const copyPublic = () =>
gulp.src(paths.public.src, { since: gulp.lastRun(copyPublic) }).pipe(gulp.dest(paths.dest));
const watch = async () => {
gulp.watch(paths.public.src, series(copyPublic, reloadBrowser));
};
const start = series(startLrServer, watch);
module.exports = { start };index.html
<!DOCTYPE html>
<html lang="en">
...
<body>
...
<script src="/frontClient.js"></script>
</body>
</html>Copy frontClient.js from node_modules/blunt-livereload/dist/frontClient.js to your public folder
Then type npx gulp start
Gulp + Webpack example
gulpfile.js
const { listen, makeBackClient, makeLrServer } = require('blunt-livereload');
const gulp = require('gulp');
const webpack = require('webpack');
const webpackConfig = require('./webpack.config.js');
const { series } = gulp;
const startLrServer = async () => {
const lrServer = makeLrServer();
return listen(lrServer);
};
const backClient = makeBackClient();
const reloadBrowser = async () => backClient.notifyWindowReload();
const compiler = webpack(webpackConfig);
const startWebpackWatch = done => {
compiler.hooks.done.tap('done', async () => reloadBrowser());
compiler.watch({}, done);
};
const start = series(startLrServer, startWebpackWatch);
module.exports = { start };webpack.config.js
Then type npx gulp start
