# gulp-cheerio

[![Build Status](https://travis-ci.org/KenPowers/gulp-cheerio.svg?branch=master)](https://travis-ci.org/KenPowers/gulp-cheerio) [![Coverage Status](https://coveralls.io/repos/KenPowers/gulp-cheerio/badge.svg?branch=master)](https://coveralls.io/r/KenPowers/gulp-cheerio?branch=master)

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

# Usage

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

```js
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:

```js
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][cpo] simply use the `parserOptions`
option:

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

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

```js
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:

```js
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`][gulpsvg]) each file will only be parsed once.
