.. warning:: There current documentation in this section does not adequately
    explain how to create custom bundles.

.. Note:: Please make sure to read the section :doc:`development` and that you have installed
    all development dependencies (long story short, you should be able to just run  ``make dev``)

Creating JavaScript and CSS bundles and distribution files
==========================================================

Converse uses `webpack <https://webpack.js.org/>`_ to create bundles containing the
core JavaScript code and all of the 3rd party dependencies.

Similarly, we use `Sass <http://sass-lang.com/>`_ to generate the CSS bundle
from ``.scss`` files in the ``sass`` directory.

The generated JavaScript bundles are contained in the `dist <https://github.com/conversejs/converse.js/tree/master/dist>`_ directory
and the generated CSS bundles in the `css <https://github.com/conversejs/converse.js/tree/master/css>`_ directory.

To generate a prticular bundle, for example the minified file ``converse.min.js``, you can run ``make dist/converse.min.js``.
This is also true for any of the other bundle files.

To generate all CSS and JavaScript bundles, you can run ``make dist``.

When you're developing, and constantly changing code, you can run ``make watch``
to let the bundles be automatically generated as soon as you edit a file.

The Converse repository does not include the minified files in the ``dist`` or
``css`` directories. Before deployment, you'll want to generate them yourself.

To only generate the minified files, you can make them individually. ::

    make dist/converse.min.js
    make css/converse.min.css


Creating custom bundles
=======================

One reason you might want to create your own bundles, is because you want to
remove some of the core plugins of Converse, or perhaps you want to include
your own.

To add or remove plugins from the build, you need to modify the
`src/converse.js <https://github.com/conversejs/converse.js/blob/master/src/converse.js>`_ file.

You'll find a section marked ``/* START: Removable components`` and
``/* END: Removable components */``.

In this section is listed the Converse plugins that will make up a bundle.

You could for example decide to disable the ControlBox altogether by removing
the ``converse-controlbox`` plugin.

After doing so, you need to run ``make dist`` again in the root or your
Converse repository, in order to generate the new build.

Be aware that some plugins might have dependencies on other plugins, so if you
remove a certain plugin but other included plugins still depend on it, then it
will still be included in your build.

To see which other plugins a particular plugin depends on, open it up in your
text editor and look at the list specified as the second parameter to the
``define`` call, near the top of the file. This list specifies the dependencies
of that plugin.

Besides the standard build, the Converse repository includes configuration
for certain other non-standard builds, which we'll now mention below.

Excluding all 3rd party dependencies
------------------------------------

The ``dist/converse-no-dependencies.js`` bundle contains only the core Converse
code and none of the 3rd party dependencies. This might be useful if you need
to load the dependencies separately.

To generate this bundle, you can run:

::

    make dist/converse-no-dependencies.js
    make dist/converse-no-dependencies.min.js

Headless build
--------------

Converse also has a special build called the `headless build`.

You can generate it by running ``make dist/converse-headless.js``

The headless build is a bundle of all the non-UI parts of Converse, and its aim
is to provide you with an XMPP library (and application) on which you can build
your own UI.

It's also installable as `@converse/headless <https://www.npmjs.com/package/@converse/headless>`_.

The main distribution of Converse relies on the headless build.

The file `src/headless/headless.js <https://github.com/jcbrand/converse.js/blob/master/src/headless/headless.js>`_
is used to determine which plugins are included in the build.
