WARNING This bundle IS NOT MAINTAINED anymore, use symfony/webpack-encore-bundle instead!!!

This bundle allows you to use the splitEntryChunks() feature from Webpack Encore by reading an entrypoins.json file and helping you render all of the dynamic script and link tags needed.

Install the bundle with:

composer require knpuniversity/webpack-encore-bundle


If you're using Symfony Flex, you're done! The recipe will pre-configure everything you need in the config/packages/webpack_encore.yaml file:

# config/packages/webpack_encore.yaml
    # The path where Encore is building the assets - i.e. Encore.setOutputPath()
    output_path: '%kernel.public_dir%/build'

    # The public prefix to your assets that you normally use with the asset() function (e.g. build/) -
    # should match the "setManifestKeyPrefix()" value in webpack.config.js, if set.
    asset_path_prefix: 'build/'


First, enable the "Split Chunks" functionality in Webpack Encore:

// webpack.config.js
// ...

    .addEntry('entry1', './assets/some_file.js')

+   .splitEntryChunks()
// ...

When you enable splitEntryChunks(), instead of just needing 1 script tag for entry1.js and 1 link tag for entry1.css, you may now need multiple script and link tags. This is because Webpack "splits" your files into smaller pieces for greater optimization.

To help with this, Encore writes a entrypoints.json file that contains all of the files needed for each "entry".

For example, to render all of the script and link tags for a specific "entry" (e.g. entry1), you can:

{# any template or base layout where you need to include a JavaScript entry #}

{% block javascripts %}
    {{ parent() }}

    {{ encore_entry_script_tags('entry1') }}
{% endblock %}

{% block stylesheets %}
    {{ parent() }}

    {{ encore_entry_link_tags('entry1') }}
{% endblock %}

Assuming that entry1 required two files to be included - vendor~entry1~entry2.js and entry1.js, then encore_entry_script_tags() is equivalent to:

<script src="{{ asset('build/vendor~entry1~entry2.js') }}"></script>
<script src="{{ asset('build/entry1.js') }}"></script>

The build/ public prefix to your assets is set in the config file.

If you want more control, you can use the encore_entry_js_files() and encore_entry_css_files() methods to get the list of files needed, then loop and create the script and link tags manually.
