Package Exports

gulp-tap

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gulp-tap) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

gulp-tap

Easily tap into a pipeline.

Uses

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.

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.

tap(function(file) {
    file.contents = Buffer.concat([
        new Buffer('HEADER'),
        file.contents
    ]);
});

If you do not return a stream, tap forwards your changes.
