Easiest way to tap into a pipeline
npm install gulp-tapEasily tap into a pipeline.
npm install gulp-tap --save-dev
Some filters like gulp-coffee process all files. What if you want to process
all JS and Coffee files in a single pipeline. Use tap to filter out .coffee
files and process them through the coffee filter and let JavaScript files
pass through.
``js`
gulp.src("src/*/.{coffee,js}")
.pipe(tap(function(file, t) {
if (path.extname(file.path) === '.coffee') {
return t.through(coffee, []);
}
}))
.pipe(gulp.dest('build'));
What if you want to change content like add a header? No need for a separate
filter, just change the content.
`js``
tap(function(file) {
file.contents = Buffer.concat([
new Buffer('HEADER'),
file.contents
]);
});
If you do not return a stream, tap forwards your changes.
