## Forked from https://github.com/dominique-mueller/angular-notifier to update for actual Angular versions. <div align="center"> # angular-notifier [![Build&Test](https://github.com/Gramli/angular-notifier/actions/workflows/ci.yml/badge.svg)](https://github.com/Gramli/angular-notifier/actions/workflows/ci.yml) </div> ## Demo You can play around with this library with **[this Stackblitz right here](https://stackblitz.com/edit/angular-notifier-demo)**. ![Angular Notifier Animated Preview GIF](/docs/angular-notifier-preview.gif?raw=true) <br><br><br> ## How to install You can get **angular-notifier** via **npm** by either adding it as a new _dependency_ to your `package.json` file and running npm install, or running the following command: ```bash npm install gramli-angular-notifier ``` <br> ### Angular versions The following list describes the compatibility with Angular: | Angular Notifier | Angular | Compilation | | ---------------- | ------- | ------------------ | | `15.x` | `17.x` | Ivy (partial mode) | | `16.x` | `18.x` | Ivy (partial mode) | | `17.x` | `19.x` | Ivy (partial mode) | For older versions visit: https://github.com/dominique-mueller/angular-notifier <br><br><br> ## How to setup Before actually being able to use the **angular-notifier** library within our code, we have to first set it up within Angular, and also bring the styles into our project. <br> ### 1. Import the `NotifierModule` First of all, make **angular-notifier** globally available to your Angular application by importing (and optionally also configuring) the `NotifierModule` the your root Angular module. For example: ```typescript import { NotifierModule } from 'gramli-angular-notifier'; @NgModule({ imports: [NotifierModule], }) export class AppModule {} ``` But wait -- your probably might want to customize your notifications' look and behaviour according to your requirements and needs. To do so, call the `withConfig` method on the `NotifierModule`, and pass in the options. For example: ```typescript import { NotifierModule } from 'gramli-angular-notifier'; @NgModule({ imports: [ NotifierModule.withConfig({ // Custom options in here }), ], }) export class AppModule {} ``` <br> ### 2. Use the `notifier-container` component In addition, you have to place the `notifier-container` component somewhere in your application, best at the last element of your root (app) component. For example: ```typescript @Component({ selector: 'my-app', template: ` <h1>Hello World</h1> <notifier-container></notifier-container> `, }) export class AppComponent {} ``` > Later on, this component will contain and manage all your applications' notifications. <br> ### 3. Import the styles Of course we also need to import the **angular-notifier** styles into our application. Depending on the architecture of your Angular application, you want to either import the original SASS files, or the already compiled CSS files instead - or none of them if you wish to write your own styles from scratch. #### The easy way: Import all the styles To import all the styles, simple include either the `~/gramli-angular-notifier/styles.(scss|css)` file. It contains the core styles as well as all the themes and notification types. #### The advanced way: Only import the styles actually needed To keep the size if your styles as small as possible (improving performance for the perfect UX), your might instead decide to only import the styles actually needed by our application. The **angular-notifier** styles are modular: - The `~/gramli-angular-notifier/styles/core.(scss|css)` file is always required, it defines the basic styles (such as the layout) - Themes can be imported from the `~/gramli-angular-notifier/styles/theme` folder - The different notification types, then, can be imported from the `~/gramli-angular-notifier/styles/types` folder <br><br><br> ## How to use Using **angular-notifier** is as simple as it can get -- simple import and inject the `NotifierService` into every component (directive, service, ...) you want to use in. For example: ```typescript import { NotifierService } from 'gramli-angular-notifier'; @Component({ // ... }) export class MyAwesomeComponent { private readonly notifier: NotifierService; constructor(notifierService: NotifierService) { this.notifier = notifierService; } } ``` <br> ### Show notifications Showing a notification is simple - all your need is a type, and a message to be displayed. For example: ```typescript this.notifier.notify('success', 'You are awesome! I mean it!'); ``` You can further pass in a _notification ID_ as the third (optional) argument. Essentially, such a _notification ID_ is nothing more but a unique string tha can be used later on to gain access (and thus control) to this specific notification. For example: ```typescript this.notifier.notify('success', 'You are awesome! I mean it!', 'THAT_NOTIFICATION_ID'); ``` > For example, you might want to define a _notification ID_ if you know that, at some point in the future, you will need to remove _this > exact_ notification. **The syntax above is actually just a shorthand version of the following:** ```typescript this.notifier.show({ type: 'success', message: 'You are awesome! I mean it!', id: 'THAT_NOTIFICATION_ID', // Again, this is optional }); ``` <br> ### Hide notifications You can also hide notifications. To hide a specific notification - assuming you've defined a _notification ID_ when creating it, simply call: ```typescript this.notifier.hide('THAT_NOTIFICATION_ID'); ``` Furthermore, your can hide the newest notification by calling: ```typescript this.notifier.hideNewest(); ``` Or, your could hide the oldest notification: ```typescript this.notifier.hideOldest(); ``` And, of course, it's also possible to hide all visible notifications at once: ```typescript this.notifier.hideAll(); ``` <br><br><br> ## How to customize From the beginning, the **angular-notifier** library has been written with customizability in mind. The idea is that **angular-notifier** works the way your want it to, so that you can make it blend perfectly into the rest of your application. Still, the default configuration should already provide a great User Experience. > Keep in mind that **angular-notifier** can be configured only once - which is at the time you import the `NotifierModule` into your root > (app) module. <br> ### Position With the `position` property you can define where exactly notifications will appear on the screen: ```typescript position: { horizontal: { /** * Defines the horizontal position on the screen * @type {'left' | 'middle' | 'right'} */ position: 'left', /** * Defines the horizontal distance to the screen edge (in px) * @type {number} */ distance: 12 }, vertical: { /** * Defines the vertical position on the screen * @type {'top' | 'bottom'} */ position: 'bottom', /** * Defines the vertical distance to the screen edge (in px) * @type {number} */ distance: 12 /** * Defines the vertical gap, existing between multiple notifications (in px) * @type {number} */ gap: 10 } } ``` <br> ### Theme With the `theme` property you can change the overall look and feel of your notifications: ```typescript /** * Defines the notification theme, responsible for the Visual Design of notifications * @type {string} */ theme: 'material'; ``` #### Theming in detail Well, how does theming actually work? In the end, the value set for the `theme` property will be part of a class added to each notification when being created. For example, using `material` as the theme results in all notifications getting a class assigned named `x-notifier__notification--material`. > Everyone - yes, I'm looking at you - can use this mechanism to write custom notification themes and apply them via the `theme` property. > For example on how to create a theme from scratch, just take a look at the themes coming along with this library (as for now only the > `material` theme). <br> ### Behaviour With the `behaviour` property you can define how notifications will behave in different situations: ```typescript behaviour: { /** * Defines whether each notification will hide itself automatically after a timeout passes * @type {number | false} */ autoHide: 5000, /** * Defines what happens when someone clicks on a notification * @type {'hide' | false} */ onClick: false, /** * Defines what happens when someone hovers over a notification * @type {'pauseAutoHide' | 'resetAutoHide' | false} */ onMouseover: 'pauseAutoHide', /** * Defines whether the dismiss button is visible or not * @type {boolean} */ showDismissButton: true, /** * Defines whether multiple notification will be stacked, and how high the stack limit is * @type {number | false} */ stacking: 4 } ``` <br> ### Custom Templates If you need more control over how the inner HTML part of the notification looks like, either because your style-guide requires it, or for being able to add icons etc, then you can **define a custom `<ng-template>`** which you pass to the `NotifierService`. You can define a custom `ng-template` as follows: ```html <ng-template #customNotification let-notificationData="notification"> <my-custom-alert type="notificationData.type"> {{ notificationData.message }} </my-custom-alert> </ng-template> ``` In this case you could wrap your own HTML, even a `<my-custom-alert>` component which you might use in your application. The notification data is passed in as a `notification` object, which you can reference inside the `<ng-template>` using the `let-` syntax. Inside your component, you can then reference the `<ng-template>` by its template variable `#customNotification` using Angular's `ViewChild`: ```typescript import { ViewChild } from '@angular/core'; @Component({ // ... }) export class SomeComponent { @ViewChild('customNotification', { static: true }) customNotificationTmpl; constructor(private notifierService: NotifierService) {} showNotification() { this.notifier.show({ message: 'Hi there!', type: 'info', template: this.customNotificationTmpl, }); } } ``` <br> ### Animations With the `animations` property your can define whether and how exactly notification will be animated: ```typescript animations: { /** * Defines whether all (!) animations are enabled or disabled * @type {boolean} */ enabled: true, show: { /** * Defines the animation preset that will be used to animate a new notification in * @type {'fade' | 'slide'} */ preset: 'slide', /** * Defines how long it will take to animate a new notification in (in ms) * @type {number} */ speed: 300, /** * Defines which easing method will be used when animating a new notification in * @type {'linear' | 'ease' | 'ease-in' | 'ease-out' | 'ease-in-out'} */ easing: 'ease' }, hide: { /** * Defines the animation preset that will be used to animate a new notification out * @type {'fade' | 'slide'} */ preset: 'fade', /** * Defines how long it will take to animate a new notification out (in ms) * @type {number} */ speed: 300, /** * Defines which easing method will be used when animating a new notification out * @type {'linear' | 'ease' | 'ease-in' | 'ease-out' | 'ease-in-out'} */ easing: 'ease', /** * Defines the animation offset used when hiding multiple notifications at once (in ms) * @type {number | false} */ offset: 50 }, shift: { /** * Defines how long it will take to shift a notification around (in ms) * @type {number} */ speed: 300, /** * Defines which easing method will be used when shifting a notification around * @type {string} */ easing: 'ease' // All standard CSS easing methods work }, /** * Defines the overall animation overlap, allowing for much smoother looking animations (in ms) * @type {number | false} */ overlap: 150 } ``` <br> ### In short -- the default configuration To sum it up, the following is the default configuration _(copy-paste-friendly)_: ```typescript const notifierDefaultOptions: NotifierOptions = { position: { horizontal: { position: 'left', distance: 12, }, vertical: { position: 'bottom', distance: 12, gap: 10, }, }, theme: 'material', behaviour: { autoHide: 5000, onClick: false, onMouseover: 'pauseAutoHide', showDismissButton: true, stacking: 4, }, animations: { enabled: true, show: { preset: 'slide', speed: 300, easing: 'ease', }, hide: { preset: 'fade', speed: 300, easing: 'ease', offset: 50, }, shift: { speed: 300, easing: 'ease', }, overlap: 150, }, }; ```
