Easily tap into a pipeline.
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 coffee filter and let JavaScript files passthrough.
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 chage the content.
tap(function(file) {
file.content = Buffer.concat([
new Buffer('HEADER'),
file.content
]);
});
If you do not return a stream, tap forwards your changes.
