Adding a new theme is really easy. There's two things you need to do: Pass the theme name to Dashy, so that it can be added to the theme selector dropdown menu, and then write some styles!
Choose a snappy name for you're theme, and add it to the `builtInThemes` array inside [`defaults.js`](https://github.com/Lissy93/dashy/blob/master/src/utils/defaults.js#L27).
##### 2. Write some Styles!
Put your theme's styles inside [`color-themes.scss`](https://github.com/Lissy93/dashy/blob/master/src/styles/color-themes.scss).
Create a new block, and make sure that `data-theme` matches the theme name you chose above. For example:
```css
html[data-theme='tiger'] {
--primary: #f58233;
--background: #0b1021;
}
```
Then you can go ahead and write you're own custom CSS. Although all CSS is supported here, the best way to define you're theme is by setting the CSS variables. You can find a [list of all CSS variables, here](https://github.com/Lissy93/dashy/blob/master/docs/theming.md#css-variables).
For a full guide on styling, see [Theming Docs](./theming.md).
Note that if you're theme is just for yourself, and you're not submitting a PR, then you can instead just pass it under `appConfig.cssThemes` inside your config file. And then put your theme in your own stylesheet, and pass it into the Docker container - [see how](https://github.com/Lissy93/dashy/blob/master/docs/theming.md#adding-your-own-theme).
Dashy is using [vue-i18n](https://vue-i18n.intlify.dev/guide/) to manage multi-language support.
Adding a new language is pretty straightforward, with just three steps:
##### 1. Create a new Language File
Create a new JSON file in `./src/assets/locales` name is a 2-digit [ISO-639 code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) for your language, E.g. for German `de.json`, French `fr.json` or Spanish `es.json` - You can find a list of all ISO codes at [iso.org](https://www.iso.org/obp/ui).
##### 2. Translate!
Using [`en.json`](https://github.com/Lissy93/dashy/tree/master/src/assets/locales/en.json) as an example, translate the JSON values to your language, while leaving the keys as they are. It's fine to leave out certain items, as if they're missing they will fall-back to English. If you see any attribute which include curly braces (`{xxx}`), then leave the inner value of these braces as is, as this is for variables.
You can also add your new language to the readme, under the [Language Switching](https://github.com/Lissy93/dashy#language-switching-) section, and optionally include your name/ username if you'd like to be credited for your work. Done!
If you are not comfortable with making pull requests, or do not want to modify the code, then feel free to instead send the translated file to me, and I can add it into the application. I will be sure to credit you appropriately.
# Adding a new option in the config file
This section is for, if you're adding a new component or setting, that requires an additional item to be added to the users config file.
All of the users config is specified in `./public/conf.yml` - see [Configuring Docs](./configuring.md) for info.
Before adding a new option in the config file, first ensure that there is nothing similar available, that is is definitely necessary, it will not conflict with any other options and most importantly that it will not cause any breaking changes. Ensure that you choose an appropriate and relevant section to place it under.
Next decide the most appropriate place for your attribute:
- Application settings should be located under `appConfig`
- Page info (such as text and metadata) should be under `pageInfo`
- Data relating to specific sections should be under `section[n].displayData`
- And for setting applied to specific items, it should be under `item[n]`
In order for the user to be able to add your new attribute using the Config Editor, and for the build validation to pass, your attribute must be included within the [ConfigSchema](https://github.com/Lissy93/dashy/blob/master/src/utils/ConfigSchema.js). You can read about how to do this on the [ajv docs](https://ajv.js.org/json-schema.html). Give your property a type and a description, as well as any other optional fields that you feel are relevant. For example:
```json
"fontAwesomeKey": {
"type": "string",
"pattern": "^[a-z0-9]{10}$",
"description": "API key for font-awesome",
"example": "0821c65656"
}
```
or
```json
"iconSize": {
"enum": [ "small", "medium", "large" ],
"default": "medium",
"description": "The size of each link item / icon"
}
```
Next, if you're property should have a default value, then add it to [`defaults.js`](https://github.com/Lissy93/dashy/blob/master/src/utils/defaults.js). This ensures that nothing will break if the user does not use your property, and having all defaults together keeps things organised and easy to manage.
If your property needs additional logic for fetching, setting or processing, then you can add a helper function within [`ConfigHelpers.js`](https://github.com/Lissy93/dashy/blob/master/src/utils/ConfigHelpers.js).
Finally, add your new property to the [`configuring.md`](./configuring.md) API docs. Put it under the relevant section, and be sure to include field name, data type, a description and mention that it is optional. If your new feature needs more explaining, then you can also document it under the relevant section elsewhere in the documentation.
- [ ] Ensure the new attribute is actually necessary, and nothing similar already exists
- [ ] Update the [Schema](https://github.com/Lissy93/dashy/blob/master/src/utils/ConfigSchema.js) with the parameters for your new option
- [ ] Set a default value (if required) within [`defaults.js`](https://github.com/Lissy93/dashy/blob/master/src/utils/defaults.js)
- [ ] Document the new value in [`configuring.md`](./configuring.md)
- [ ] Test that the reading of the new attribute is properly handled, and will not cause any errors when it is missing or populated with an unexpected value
Running `yarn upgrade` will updated all dependencies based on the ranges specified in the `package.json`. The `yarn.lock` file will be updated, as will the contents of `./node_modules`, for more info, see the [yarn upgrade documentation](https://classic.yarnpkg.com/en/docs/cli/upgrade/). It is important to thoroughly test after any big dependency updates.
When Dashy is deployed to Netlify, it is effectively running as a static app, and therefore the server-side code for the Node.js endpoints is not available. However Netlify now supports serverless cloud lambda functions, which can be used to replace most functionality.
#### 1. Run Netlify Dev Server
First off, install the Netlify CLI: `npm install netlify-cli -g`
Then, from within the root of Dashy's directory, start the server, by running: `netlify dev`
#### 2. Create a lambda function
This should be saved it in the [`./services/serverless-functions`](https://github.com/Lissy93/dashy/tree/master/services/serverless-functions) directory
```javascript
exports.handler = async () => ({
statusCode: 200,
body: 'Return some data here...',
});
```
#### 3. Redirect the Node endpoint to the function
In the [`netlify.toml`](https://github.com/Lissy93/dashy/blob/FEATURE/serverless-functions/netlify.toml) file, add a 301 redirect, with the path to the original Node.js endpoint, and the name of your cloud function
For some pages (such as the login page, the minimal start page, etc) the basic page furniture, (like header, footer, nav, etc) is not needed. This section explains how you can hide furniture on a new view (step 1), or add a component that should be hidden on certain views (step 2).
##### 1. Add the route name to the should hide array
In [`./src/utils/defaults.js`](https://github.com/Lissy93/dashy/blob/master/src/utils/defaults.js), there's an array called `hideFurnitureOn`. Append the name of the route (the same as it appears in [`router.js`](https://github.com/Lissy93/dashy/blob/master/src/router.js)) here.
##### 2. Add the conditional to the structural component to hide
First, import the helper function:
```javascript
import { shouldBeVisible } from '@/utils/MiscHelpers';
```
Then you can create a computed value, that calls this function, passing in the route name:
```javascript
export default {
...
computed: {
...
isVisible() {
return shouldBeVisible(this.$route.name);
},
},
};
```
Finally, in the markup of your component, just add a `v-if` statement, referencing your computed value
All environmental variables are optional. Currently there are not many environmental variables used, as most of the user preferences are stored under `appConfig` in the `conf.yml` file.
You can set variables either in your environment, or using the [`.env`](https://github.com/Lissy93/dashy/blob/master/.env) file.
Any environmental variables used by the frontend are preceded with `VUE_APP_`. Vue will merge the contents of your `.env` file into the app in a similar way to the ['dotenv'](https://github.com/motdotla/dotenv) package, where any variables that you set on your system will always take preference over the contents of any `.env` file.
If add any new variables, ensure that there is always a fallback (define it in [`defaults.js`](https://github.com/Lissy93/dashy/blob/master/src/utils/defaults.js)), so as to not cause breaking changes. Don't commit the contents of your `.env` file to git, but instead take a few moments to document what you've added under the appropriate section. Try and follow the concepts outlined in the [12 factor app](https://12factor.net/config).
