# Develop custom branches with GeoNode MapStore Client

This section demonstrates how to set up the GeoNode MapStore Client to work on custom branches. It should only take into account the advanced/complex changes that the previously described customization could not support

## Build the client to make it available in a static directory

Create a new branch with

```shell
cd /opt/client/geonode-mapstore-client
git checkout -b my_custom_branch
```

Apply all the changes to the js code, python files, or templates and see the update at http://localhost:8081/

Commit your changes

```shell
git commit -m "my custom changes to the project"
```

Compile your bundle with

```shell
npm run compile
```

The compile process will move all the bundles and static files from `geonode-mapstore-client/geonode_mapstore_client/client/` to `geonode-mapstore-client/geonode_mapstore_client/static/`

Commit the compiled bundle

```shell
git commit -m "update client bundle"
```

You could create a fork from the [geonode-mapstore-client](https://github.com/GeoNode/geonode-mapstore-client) github page and then add the remote to your local repository

```shell
git remote add {my_fork_name} https://github.com/{my_fork_name}/geonode-mapstore-client
```

Finally, push your branch to your remote repository

```shell
git push {my_fork_name} my_custom_branch
```

**Note**
    {my_fork_name} should be replaced with the name of your fork, usually the username or organization name in github

## Update the requirement.txt of the geonode-project

It is now possible to install the custom branch inside the geonode-project by updating the `requirement.txt` to point to a specific branch of the django_geonode_mapstore_client. Here is an example:

```shell
cd /opt/geonode-project/my_geonode/src
vim requirements.txt
```

```
-e git+https://github.com/{my_fork_name}/geonode-mapstore-client.git@my_custom_branch#egg=django_geonode_mapstore_client
```

```shell
cd /opt/geonode-project/my_geonode/src
pip install -r requirement.txt
```
