gulp-mirror
v1.0.0 gulp gulpplugin stream mirror plugin
gulp-mirror
Make a mirror of stream, it's useful that do different transform of the same stream.
Install
$ npm install gulp-mirror
Usage
Real world example.
var gulp = require('gulp');
var concat = require('gulp-concat');
var mirror = require('gulp-mirror');
var rename = require('gulp-rename');
gulp.task('default', function() {
return gulp.src('src/**/*.js')
.pipe(concat('all.js'))
.pipe(mirror(
rename('browser.js'),
rename('common.js'),
rename('node.js')
))
.pipe(gulp.dest('dist'));
});
Concat all js files in src directory, then rename it using mirror that will create three files which are the same.
API
mirror(stream1, stream2 ..., streamN)
Pass the input stream to all the mirrored stream with cloned File
object. The mirrored stream also can be pipeline stream using multipipe, see example 2.
gulp.src(source)
.pipe(sharedStream1)
.pipe(mirror(
stream1,
stream2,
...
streamN
))
.pipe(sharedStream2)
.pipe(gulp.dest(dest));
Stream flow
--> stream1 -->
/ \
src --> sharedStream1 --> stream2 -->
\ \
--> ... --> sharedStream2 --> dest
\ /
--> streamN -->
if mirror has only one argument, it will create another passthrough stream, just like gulp-clone, See example 3.
mirror([stream1, stream2 ..., streamN])
Sometimes the number of streams is variable, then we can pass to mirror
an array of streams as unique argument.
