## 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.

  - 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"

# 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"
    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/"

        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:

```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}
```
