gulp-cond

Ternary operator for Gulp.

Usage

First, install gulp-cond as a development dependency:

npm install --save-dev gulp-cond

Then, use it to conditionally pipe plugins in your gulpfile.js:

import cond from 'gulp-cond';
var prod = gulp.env.prod;

// Images
gulp.task('build_images', function() {
  gulp.src('assets/images/**/*.svg')
    .pipe(cond(prod,
      gSvgmin(options), // minify SVG images under production
      gWatch().pipe(gLivereload(server))) // use live reload in dev mode
    )
    .pipe(gulp.dest('www/images'))
});

Alternatively, you can provide plugin functions instead of streams to instantiate streams only when needed :

import cond from 'gulp-cond';
var prod = gulp.env.prod;

// Images
gulp.task('build_images', function() {
  gulp.src('assets/images/**/*.svg')
    .pipe(cond(prod,
      gSvgmin.bind(null, options), // minify SVG images under production
      function () { // use live reload in dev mode
        return gWatch().pipe(gLivereload(server));
      })
    )
    .pipe(gulp.dest('www/images'))
});
