# Presentation layer
|
|
|
|
- Consists of Vue.js components and other UI-related code.
|
|
- Desktop application is created using [Electron](https://www.electronjs.org/).
|
|
- Event driven as in components simply listens to events from the state and act accordingly.
|
|
|
|
## Structure
|
|
|
|
- [`/src/` **`presentation/`**](./../src/presentation/): Contains all presentation related code including Vue and Electron configurations
|
|
- [**`bootstrapping/`**](./../src/presentation/bootstrapping/): Registers Vue global objects including components and plugins.
|
|
- [**`components/`**](./../src/presentation/components/): Contains all Vue components and their helper classes.
|
|
- [**`Shared/`**](./../src/presentation/components/Shared): Contains Vue components and component helpers that are shared across other components.
|
|
- [**`styles/`**](./../src/presentation/styles/): Contains shared styles used throughout different components.
|
|
- [**`main.ts`**](./../src/presentation/main.ts): Application entry point that mounts and starts Vue application.
|
|
- [**`background.ts`**](./../src/presentation/background.ts): Main process of Electron, started as first thing when app starts.
|
|
- [**`/public/`**](./../public/): Contains static assets that will simply be copied and not go through webpack.
|
|
- [**`/vue.config.js`**](./../vue.config.js): Global Vue CLI configurations loaded by `@vue/cli-service`
|
|
- [**`/postcss.config.js`**](./../postcss.config.js): PostCSS configurations that are used by Vue CLI internally
|
|
- [**`/babel.config.js`**](./../babel.config.js): Babel configurations for polyfills used by `@vue/cli-plugin-babel`
|
|

## Application data
|
|
|
|
- Components and should use [ApplicationFactory](./../src/application/ApplicationFactory.ts) singleton to reach the application domain.
|
|
- [Application.ts](../src/domain/Application.ts) domain model is the stateless application representation including
|
|
- available scripts, collections as defined in [collection files](./collection-files.md)
|
|
- package information as defined in [`package.json`](./../package.json)
|
|
- 📖 See [Application data | Application layer](./presentation.md#application-data) where application data is parsed and compiled.
|
|
|
|
## Application state
|
|
|
|
- Stateful components mutate or/and react to state changes in [ApplicationContext](./../src/application/Context/ApplicationContext.ts).
|
|
- Stateless components that does not handle state extends `Vue`
|
|
- Stateful components that depends on the collection state such as user selection, search queries and more extends [`StatefulVue`](./../src/presentation/components/Shared/StatefulVue.ts)
|
|
- The single source of truth is a singleton of the state created and made available to presentation layer by [`StatefulVue`](./../src/presentation/components/Shared/StatefulVue.ts)
|
|
- `StatefulVue` includes abstract `handleCollectionState` that is fired once the component is loaded and also each time [collection](./collection-files.md) is changed.
|
|
- Do not forget to subscribe from events when component is destroyed or if needed [collection](./collection-files.md) is changed.
|
|
- 💡 `events` in base class [`StatefulVue`](./../src/presentation/components/Shared/StatefulVue.ts) makes lifecycling easier
|
|
- 📖 See [Application state | Application layer](./presentation.md#application-state) where the state is implemented using using state pattern.
|
|
|
|
## Modals
|
|
|
|
- [Dialog.vue](./../src/presentation/components/Shared/Dialog.vue) is a shared component that can be used to show modal windows
|
|
- Simply wrap the content inside of its slot and call `.show()` method on its reference.
|
|
- Example:
|
|
|
|
```html
|
|
<Dialog ref="testDialog">
|
|
<div>Hello world</div>
|
|
</Dialog>
|
|
<div @click="$refs.testDialog.show()">Show dialog</div>
|
|
```
