## Configuration

Title, icons, links, colors, and services can be configured in the `config.yml` file (located in `/assets` directory once built, or in the `public/assets` directory in development mode), using [yaml](http://yaml.org/) format.

# Optional message
message:
  # url: "https://<my-api-endpoint>" # Can fetch information from an endpoint to override value below.
  # mapping: # allows to map fields from the remote format to the one expected by Homer
  #   title: 'id' # use value from field 'id' as title
  #   content: 'value' # value from field 'value' as content
  # refreshInterval: 10000 # Optional: time interval to refresh message
  #
  # Real example using chucknorris.io for showing Chuck Norris facts as messages:
  # url: https://api.chucknorris.io/jokes/random
  # mapping:
  #   title: 'id'
  #   content: 'value'
  # refreshInterval: 10000
  style: "is-warning"
  title: "Optional message!"
  icon: "fa fa-exclamation-triangle"
  content: "Lorem ipsum dolor sit amet, consectetur adipiscing elit."

# Optional navbar
# links: [] # Allows for navbar (dark mode, layout, and search) without any links
links:
  - name: "Link 1"
    icon: "fab fa-github"
    url: "https://github.com/bastienwirtz/homer"
    target: "_blank" # optional html tag target attribute
  - name: "link 2"
    icon: "fas fa-book"
    url: "https://github.com/bastienwirtz/homer"
  # this will link to a second homer page that will load config from page2.yml and keep default config values as in config.yml file
  # see url field and assets/page.yml used in this example:
  - name: "Second Page"
    icon: "fas fa-file-alt"
    url: "#page2"

# Services
# First level array represents a group.
# Leave only a "items" key if not using group (group name, icon & tagstyle are optional, section separation will not be displayed).
services:
  - name: "Application"
    icon: "fas fa-code-branch"
    # A path to an image can also be provided. Note that icon take precedence if both icon and logo are set.
    # logo: "path/to/logo"
    items:
      - name: "Awesome app"
        logo: "assets/tools/sample.png"
        # Alternatively a fa icon can be provided:
        # icon: "fab fa-jenkins"
        subtitle: "Bookmark example"
        tag: "app"
        url: "https://www.reddit.com/r/selfhosted/"
        target: "_blank" # optional html tag target attribute
      - name: "Another one"
        logo: "assets/tools/sample2.png"
        subtitle: "Another application"
        tag: "app"
        # Optional tagstyle
        tagstyle: "is-success"
        url: "#"
  - name: "Other group"
    icon: "fas fa-heartbeat"
    items:
      - name: "Pi-hole"
        logo: "assets/tools/sample.png"
        # subtitle: "Network-wide Ad Blocking" # optional, if no subtitle is defined, PiHole statistics will be shown
        tag: "other"
        url: "http://192.168.0.151/admin"
        type: "PiHole" # optional, loads a specific component that provides extra features. MUST MATCH a file name (without file extension) available in `src/components/services`
        target: "_blank" # optional html a tag target attribute
        # class: "green" # optional custom CSS class for card, useful with custom stylesheet
        # background: red # optional color for card to set color directly without custom stylesheet
```

If you choose to fetch message information from an endpoint, the output format should be as follows (or you can [custom map fields as shown in tips-and-tricks](./tips-and-tricks.md#mapping-fields)):

```json
{
  "style": null,
  "title": "Lorem ipsum 42",
  "content": "LA LA LA Lorem ipsum dolor sit amet, ....."
}
```

`null` value or missing keys will be ignored and value from the `config.yml` will be used if available.
Empty values (either in `config.yml` or the endpoint data) will hide the element (ex: set `"title": ""` to hide the title bar).

### Style Options

Homer uses [bulma CSS](https://bulma.io/), which provides a [modifiers syntax](https://bulma.io/documentation/modifiers/syntax/). You'll notice in the config there is a `tagstyle` option. It can be set to any of the bulma modifiers. You'll probably want to use one of these 4 main colors:

- `is-info` (blue)
- `is-success` (green)
- `is-warning` (yellow)
- `is-danger` (red)

You can read the [bulma modifiers page](https://bulma.io/documentation/modifiers/syntax/) for other options regarding size, style, or state.

### PWA Icons

In order to easily generate all required icon preset for the PWA to work, a tool like [vue-pwa-asset-generator](https://www.npmjs.com/package/vue-pwa-asset-generator) can be used:

```bash
npx vue-pwa-asset-generator -a {your_512x512_source_png} -o {your_output_folder}
```

### Supported services

Currently the following services are supported for showing quick infos on the card. They can be used by setting the type to one of the following values at the item.

- PiHole
- AdGuardHome
- PaperlessNG

### Additional configuration

#### Paperless
For Paperless you need an API-Key which you have to store at the item in the field `apikey`.
