Description
"Automate and enhance your workflow" This is how Gulp presents itself, Gulp is a task runner, combined with an API of file streams.
This runner is based on Gulp 4.
[TOC]
Features
- Create any gulp task
- Combine tasks in parallel or in series
- Create file watchers that run tasks or anything else on change.
Adding Gulp tasks
module.exports = {
/**
* Represents the extension point for Gulp configuration
* @param {Crafty} crafty - The instance of Crafty.
* @param {Gulp} gulp - The instance of Gulp.
* @param {StreamHandler} StreamHandler - A wrapper to create your tasks.
*/
gulp(crafty, gulp, StreamHandler) {
// Create tasks
gulp.task("images_svg", function() {
const stream = new StreamHandler("images/**/*.svg", "dist/images");
stream.add(svgmin());
return stream.generate();
});
// Group tasks into other tasks
gulp.task("images", gulp.parallel("images_svg"));
// Register this task to run automatically
crafty.addDefaultTask("images");
// Create custom watchers
gulp.watch(["js/*.js"]).on("change", function(path) {
console.log("Change happened to", path);
});
}
};
The full API of Gulp is supported
Slight change in behavior of gulp.watch()
We changed the behavior of gulp.watch()
in Crafty compared to how it works in
Gulp: Instead of watching directly, the watch will start when running crafty watch
.
This creates a clear separation between development and production builds.
StreamHandler
StreamHandler
is a utility class to help you create your streams.
It works the same way as gulp.src()...pipe(gulp.dest())
but with some added
syntactic sugar:
- Doesn't return a new instance on every
pipe
thus allowing you to create complex streams without re-assigning the variable every time - Includes
gulp-plumber
to catch errors
gulp.task("images_svg", function() {
const stream = new StreamHandler("images/**/*.svg", "dist/images");
stream.add(svgmin());
return stream.generate();
});
new StreamHandler(source, destination[, callback])
source
is a glob or array of globsdestination
is a destination file or directorycallback(error)
is an optional node-style callback that you can set to be called once the stream has finished processing
stream.add(handler)
Same as .pipe(handler)
generate()
Generates the stream and returns it.
