The developer docs are here:
https://conversejs.org/docs/html/development.html

## Quickstart

### With GNU Make:

```
make serve_bg
make watch
```

Go to http://localhost:8000/dev.html

Then modify `dev.html` so that `converse.initialize()` is called with relevant settings.


### Without GNU Make:

```
npm install
npm run serve &
npm run watch
```

Webpack will "watch" the source files and automatically recreate the build if they
are modified. So you don't have to do anything to rebuild whenever you've
change something in a file but you will have to manually reload the browser tab
to see the changes in the browser.


## Live reloading

If you want to have live reloading whenever any of the source files change, you
can run ``make devserver`` (or ``npm run devserver``).

Then go to http://localhost:8080

Then modify `webpack.html` so that `converse.initialize()` is called with relevant settings.

We use development tools which depend on Node.js and NPM (the Node package manager).

It's recommended that you use `NVM <https://github.com/nvm-sh/nvm>`_ (the Node version manager)
to make sure you have the right version of Node.

Refer to the `NVM Github page <https://github.com/nvm-sh/nvm#install--update-script>`_ for instructions on how to install it.

Once NVM is installed, you can run the following inside your checkout of the Converse Git repository:
To set up a Converse development environment, you now run the following:

::

nvm install
make serve_bg
make watch

.. note::
You will always have to first run ``nvm install`` in a new terminal session in order to use the
recommended version of Node before working on Converse.
Alternatively, if you're using Windows, or don't have GNU Make installed, you can run the
following:

::

To set up the Converse development environment, you now run ``make dev``.
npm install
npm run serve &
npm run watch

::

make dev
Then go to http://localhost:8000/dev.html to load Converse.

Alternatively, if you're using Windows, or don't have GNU Make installed, you can run the
following:
Modify `dev.html <https://github.com/conversejs/converse.js/blob/master/dev.html>`_
so that `converse.initialize()` is called with the relevant settings.

Webpack will "watch" the source files and automatically recreate the build if they
are modified. So you don't have to do anything to rebuild whenever you've
change something in a file but you will have to manually reload the browser tab
to see the changes in the browser.

Live reloading
--------------

If you want to have live reloading whenever any of the source files change, you
can run ``make devserver`` (or ``npm run devserver``) which uses `webpack-dev-server <https://github.com/webpack/webpack-dev-server>`_.

npm install
npm run lerna
Then go to http://localhost:8080.

This will install the Node development tools and Converse's dependencies.
Instead of ``dev.html``, `webpack.html <https://github.com/conversejs/converse.js/blob/master/webpack.html>`_
is now being used as the served HTML file, and you'll need to modify that file to
change the settings passed to ``converse.initialize``.

The front-end dependencies are those JavaScript files on which
Converse directly depends and which will be loaded in the browser as part of
the bundle in ``dist/converse.js`` (or ``dist/converse.min.js``).
Troubleshooting
---------------

To see the 3rd party dependencies (not just the front-end dependencies, but
also ones necessary for development tasks like making builds), take a look at
the list under the ``devDependencies`` in `package.json <https://github.com/jcbrand/converse.js/blob/master/package.json>`_.
After running ``make watch``, you should now have a new *node_modules* directory
which contains all the external dependencies of Converse.

.. note::
After running ```make dev```, you should now have a new *node_modules* directory
which contains all the external dependencies of Converse.
If this directory does NOT exist, something must have gone wrong.
Double-check the output of ```make dev``` to see if there are any errors
listed. For support, you can ask in our chatroom: `[email protected] <xmpp:[email protected]>`_.

.. _`webserver`:

Setting up a webserver
======================

When making changes to Converse, either development or theming changes,
you'll want to preview them in your browser.

For this, you'll need to serve the development files via a web server,
so that you can see your local changes in the browser.

Manually starting a web server
------------------------------

To both set up the development environment and also start up a web browser to
serve the files for you, you can run::

make serve

.. note::
To run the "make" commands, you'll need `GNUMake <https://www.gnu.org/software/make>`_
installed on your computer. If you use GNU/Linux or \*BSD, it should be installed or
available via your package manager. For Mac, you'll need to install XCode and in
Windows you can use `Chocolatey <https://chocolatey.org/>`_.

After running ``make serve`` you can open http://localhost:8000 in your webbrowser to see the Converse website.

When developing or changing the theme, you'll want to load all the
unminified JS and CSS resources as separate files. To do this, open http://localhost:8000/dev.html instead.

You might want to open `dev.html <https://github.com/conversejs/converse.js/blob/master/dev.html>`_ in your text editor or IDE as well, to see
how ``converse.initialize`` is called and to potentially change any of the
settings.

Starting a web server with live reloading
-----------------------------------------

Alternatively, if you want to have live reloading whenever any of the source files change, you
can run ``make devserver`` (which will use `webpack-dev-server <https://github.com/webpack/webpack-dev-server>`_).

Instead of ``dev.html`` being used, `webpack.html <https://github.com/conversejs/converse.js/blob/master/webpack.html>`_
is now being used as the HTML template, and you'll need to modify that file if
you want to change the settings passed to ``converse.initialize``.

If you're running ``make devserver``, you need to open http://localhost:8080.
