This offers the official frontend to control Home Assistant. This integration is by default enabled, unless you've disabled or removed the [`default_config:`](https://www.home-assistant.io/integrations/default_config/) line from your configuration. If that is the case, the following example shows you how to enable this integration manually:
```yaml
# Example configuration.yaml entry
frontend:
```
{% configuration %}
javascript_version:
description: "DEPRECATED, it is now done using feature detection in the browser. Version of the JavaScript to serve to clients. Options: `es5` - transpiled so old browsers understand it. `latest` - not transpiled, so will work on recent browsers only. `auto` - select a version according to the browser user-agent. The value in the configuration can be overiden by putting `es5` or `latest` in the URL. For example `http://localhost:8123/states?es5` "

## Defining Themes
Starting with version 0.49 you can define themes:
```yaml
# Example configuration.yaml entry
frontend:
themes:
happy:
primary-color: pink
sad:
primary-color: blue
```
The example above defined two themes named `happy` and `sad`. For each theme you can set values for CSS variables. For a partial list of variables used by the main frontend see [ha-style.ts](https://github.com/home-assistant/home-assistant-polymer/blob/master/src/resources/ha-style.ts).
Check our [community forums](https://community.home-assistant.io/c/projects/themes) to find themes to use.
### Theme automation
There are 2 themes-related services:
- `frontend.reload_themes`: reloads theme configuration from your `configuration.yaml` file.
- `frontend.set_theme(name)`: sets backend-preferred theme name.
Example in automation:
Set a theme at the startup of Home Assistant:
```yaml
automation:
- alias: 'Set theme at startup'
trigger:
- platform: homeassistant
event: start
action:
service: frontend.set_theme
data:
name: happy
```
To enable "night mode":
```yaml
automation:
- alias: 'Set dark theme for the night'
trigger:
- platform: time
at: '21:00:00'
action:
- service: frontend.set_theme
data:
name: darkred
```
### Manual Theme Selection
When themes are enabled in the `configuration.yaml` file, a new option will show up in the user profile page (accessed by clicking your user account initials at the bottom of the sidebar). You can then choose any installed theme from the dropdown list and it will be applied immediately.

<img src='/images/frontend/user-theme.png' />

## Loading extra HTML
Starting with version 0.53 you can specify extra HTML files to load, and starting with version 0.95 extra JS modules.
Example:
```yaml
# Example configuration.yaml entry
frontend:
extra_html_url:
- https://example.com/file1.html
- /local/file2.html
extra_module_url:
- /local/my_module.js
```
HTML will be loaded via `<link rel='import' href='{{ extra_url }}' async>` on any page (states and panels), and modules via `<script type='module' scr='{{ extra_module }}'></script>`.
### Manual Language Selection
The browser language is automatically detected. To use a different language, go to the user profile page (accessed by clicking your user account initials at the bottom of the sidebar) and select one. It will be applied immediately.
