To set up a Gulp watch task, first install
Gulp and its
plugins. Create a
gulpfile.js at the root of your project directory. Inside this file, require Gulp and any necessary plugins. Define tasks that perform actions on your files such as compiling or minifying.
For a watch task, use the ‘
gulp.watch’ method. This takes two arguments: the path to the files to monitor, and the tasks to run when those files change. For example:
var gulp = require('gulp');
gulp.task('watch', function() {
gulp.watch('src/js/*.js', ['jshint']);
});​
In this example, Gulp watches for changes in JavaScript files within the ‘
src/js’ directory. When a change is detected, it runs the ‘
jshint’ task.
Remember to call your watch task from the command line using ‘
gulp watch’.
