gulp-cheerio

This is a plugin for gulp which allows you to manipulate HTML and XML files using cheerio.

Usage

There are two ways to use gulp-cheerio: synchronous and asynchronous. See the following usage examples:

var gulp = require('gulp'),
  cheerio = require('gulp-cheerio');

gulp.task('sync', function() {
  return gulp
    .src(['src/*.html'])
    .pipe(
      cheerio(function($, file) {
        // Each file will be run through cheerio and each corresponding `$` will be passed here.
        // `file` is the gulp file object
        // Make all h1 tags uppercase
        $('h1').each(function() {
          var h1 = $(this);
          h1.text(h1.text().toUpperCase());
        });
      }),
    )
    .pipe(gulp.dest('dist/'));
});

gulp.task('async', function() {
  return gulp
    .src(['src/*.html'])
    .pipe(
      cheerio(function($, file, done) {
        // The only difference here is the inclusion of a `done` parameter.
        // Call `done` when everything is finished. `done` accepts an error if applicable.
        done();
      }),
    )
    .pipe(gulp.dest('dist/'));
});

Additional options can be passed by passing an object as the main argument with your function as the run option:

var gulp = require('gulp'),
  cheerio = require('gulp-cheerio');

gulp.task('sync', function() {
  return gulp
    .src(['src/*.html'])
    .pipe(
      cheerio({
        run: function($, file) {
          // Each file will be run through cheerio and each corresponding `$` will be passed here.
          // `file` is the gulp file object
          // Make all h1 tags uppercase
          $('h1').each(function() {
            var h1 = $(this);
            h1.text(h1.text().toUpperCase());
          });
        },
      }),
    )
    .pipe(gulp.dest('dist/'));
});

gulp.task('async', function() {
  return gulp
    .src(['src/*.html'])
    .pipe(
      cheerio({
        run: function($, file, done) {
          // The only difference here is the inclusion of a `done` parameter.
          // Call `done` when everything is finished. `done` accepts an error if applicable.
          done();
        },
      }),
    )
    .pipe(gulp.dest('dist/'));
});

If you want to use custom parser options simply use the parserOptions option:

cheerio({
  run: function() {},
  parserOptions: {
    // Options here
  },
});

When the xmlMode option is set to true cheerio's $.xml() method will be used to render:

cheerio({
  run: function() {},
  parserOptions: {
    xmlMode: true,
  },
});

This module includes cheerio version 0.*. If you want to use your own special build / version of cheerio, you can pass it in as an option:

cheerio({
  cheerio: require('my-cheerio'), // special version of `cheerio`
});

As of version 0.4.0 the parsed $ object returned from cheerio.load(...) is cached to gulp's file object as file.cheerio. gulp-cheerio will look for file.cheerio before attempting to use cheerio.load(...). This means that if you use gulp-cheerio multiple times in the same stream or with another plugin that supports caching cheerio in this fashion (such as gulp-svgstore) each file will only be parsed once.
