## Build
## Why skeletons?
Run `ng build ngx-skeleton-loader` to build the project. The build artifacts will be stored in the `dist/` directory.
> If you want to get more details about that, please read ["NGX-Skeleton-Loader — States, Animations, Performance, and Accessibility for your Angular App"](https://willmendesneto.com/posts/ngx-skeleton-loader-states-animations-performance-and-accessibility-for-your-angular-app) blog post
## Publishing
The idea of this component is make the process transparent and easier. So the main point is integrate this component with other tooling process, such as:
After building your library with `ng build ngx-skeleton-loader`, go to the dist folder `cd dist/ngx-skeleton-loader` and run `npm publish`.
- Server-side rendering;
- Progressive rendering;
- Any other that you like :)
## Running unit tests
It's totally transparent for you and you can integrate easier in your application, improving your user experience 🎉
Run `ng test ngx-skeleton-loader` to execute the unit tests via [Karma](https://karma-runner.github.io).

## Install
You can get it on NPM installing `ngx-skeleton-loader` module as a project dependency.
```shell
npm install ngx-skeleton-loader --save
```
## Setup
You'll need to add `NgxSkeletonLoaderModule` to your application module. So that, the `<ngx-skeleton-loader>` components will be accessible in your application.
```typescript
...
import { NgxSkeletonLoaderModule } from 'ngx-skeleton-loader';
...
@NgModule({
declarations: [
YourAppComponent
],
imports: [
...
NgxSkeletonLoaderModule,
...
],
providers: [],
bootstrap: [YourAppComponent]
})
export class YourAppComponent {}
```
After that, you can use the `ngx-skeleton-loader` components in your templates, passing the configuration data into the component itself.
- `ngx-skeleton-loader`: Handle the skeleton animation and the skeleton styles of your app;
```html
<div class="item">
<ngx-skeleton-loader count="5" appearance="circle"></ngx-skeleton-loader>
</div>
```
### Using `NgxSkeletonLoaderModule.forRoot()`
Also, you can import the module in your app by calling `NgxSkeletonLoaderModule.forRoot()` when adding it. So it will be available across your Angular application.
Importing the module this way also allows you to globally configure the default values for the `ngx-skeleton-loader` components in your application, in case you need some different default values for your app.
```typescript
...
import { NgxSkeletonLoaderModule } from 'ngx-skeleton-loader';
...
@NgModule({
declarations: [
YourAppComponent
],
imports: [
...
NgxSkeletonLoaderModule.forRoot({ animation: 'pulse', loadingText: 'This item is actually loading...' }),
...
],
providers: [],
bootstrap: [YourAppComponent]
})
export class YourAppComponent {}
```
```html
<div class="item">
<ngx-skeleton-loader count="5" appearance="circle"></ngx-skeleton-loader>
<!-- above line will produce the rendering of 5 circles with the pulse animation and the aria-valuetext attribute set with "This item is actually loading..." -->
</div>
```
#### Extending `theme` via `NgxSkeletonLoaderModule.forRoot()`
> By default when using `NgxSkeletonLoaderModule.forRoot({ theme: /* ...list of CSS atributes */} })` the application is using this value as source of truth, overriding any local theming passed to `<ngx-skeleton-loader>` component via `[theme]` input. Check these steps in case you need to change this behaviour in your app
This method is also accepting the option of having a global theme and local theme inputs. You can enable it by passing `NgxSkeletonLoaderModule.forRoot({ theme: { extendsFromRoot: true, /* ...list of CSS atributes */} })` in your module. Quite simple, right? 😄
By using that configuration in your application, you should also be aware that:
- By default, every `<ngx-skeleton-loader>` component will use `theme` coming from `NgxSkeletonLoaderModule.forRoot()` as the source of truth
- If there's any CSS attribute on the component locally which overrides the CSS spec, it combines both themes, but overriding global CSS attributes in favor of local ones.
As an example:
```typescript
...
import { NgxSkeletonLoaderModule } from 'ngx-skeleton-loader';
...
@NgModule({
declarations: [
YourAppComponent
],
imports: [
...
NgxSkeletonLoaderModule.forRoot({
theme: {
// Enabliong theme combination
extendsFromRoot: true,
// ... list of CSS theme attributes
height: '30px',
},
}),
...
],
providers: [],
bootstrap: [YourAppComponent]
})
export class YourAppComponent {}
```
```html
<div class="item">
<ngx-skeleton-loader></ngx-skeleton-loader>
<!-- above line will produce a skeleton component using `height: 30px;`" -->
<ngx-skeleton-loader [theme]="{background: 'blue'}"></ngx-skeleton-loader>
<!-- above line will produce a skeleton component using `height: 30px; background: blue;`" -->
<ngx-skeleton-loader [theme]="{height: '50px', background: 'red'}"></ngx-skeleton-loader>
<!-- above line will produce a skeleton component using `height: 50px; background: red;`" -->
</div>
```
## WAI-ARIA values
- loadingText - _default_ `Loading...`: attribute that defines the text value for `aria-valuetext` attribute. Defaults to "Loading..."
- `aria-label` - _default_ `loading`: you can add `ariaLabel` as input of the component to set a different value.
## Appearance
You can also define which appearance want to use in your skeleton loader by passing the options in your component via `[appearance]` attribute.
### Options
- `''` - _default_: it will use it `''` as appearance. At the end, it will render like a line;
- `line`: it will render like a line. This is the same behavior as passing an empty string;
- `circle`: it will use `circle` as appearance. Great for avatar skeletons, for example :);
- `custom-content`: it will NOT add any appearance. Great for custom content, such as SVG, internal components and such;
## Animations
You can also define which CSS animation you want to use - even not use any, if it's the case - in your skeleton loader by passing the options in your component via `[animation]` attribute.
### Options
- `"false"` (as string): it will disable the animation;
- `false` (as boolean): it will disable the animation. Animation will receive `false` as string when attribute field it's not using binding. Component now can receive `false` (boolean), "false" (string), or any other animation type via binding;
- `progress` - _default_: it will use it `progress` as animation;
- `progress-dark`: it will use it `progress-dark` as animation. Recommended if your color schema is darken;
- `pulse`: it will use `pulse` as animation;
> `progress` is the default animation, used as the single one previously. If you don't pass the animation attribute, it defaults to `progress`.
```html
<!--
If you need to change all the background wrapper
you need to apply the style changes on the
`ngx-skeleton-loader` component wrapper
-->
<div class="item">
<!-- Disables the animation -->
<ngx-skeleton-loader animation="false"></ngx-skeleton-loader>
<!-- Disables the animation, but receiving boolean value from binding -->
<!-- Via binding it can receive `false` (boolean), "false" (string), or any other animation type -->
<ngx-skeleton-loader [animation]="classAttributeWithBooleanFalseValue"></ngx-skeleton-loader>
<!-- Uses `progress` as animation -->
<ngx-skeleton-loader animation="progress"></ngx-skeleton-loader>
<ngx-skeleton-loader></ngx-skeleton-loader>
<!-- Uses `pulse` as animation -->
<ngx-skeleton-loader animation="pulse"></ngx-skeleton-loader>
</div>
```
> You can check the code details in the [Stackblitz Live Demo Link](https://stackblitz.com/edit/ngx-skeleton-loader-sample?file=app%2Fapp.component.html)
## Theming
You can also define different styles for the skeleton loader by passing an object with the css styles - in dashed case - into the component via `[theme]` attribute.
```html
<!--
If you need to change all the background wrapper
you need to apply the style changes on the
`ngx-skeleton-loader` component wrapper
-->
<div style="background: #FF0001; padding: 10px;">
<ngx-skeleton-loader
count="5"
[theme]="{
'border-radius': '5px',
height: '50px',
'background-color': '#992929',
border: '1px solid white'
}"
></ngx-skeleton-loader>
</div>
```
The [theme] attribute now accepts the same configuration as `ngStyle` as well. That means you can manage to use like you're doing with the built-in directive, having a pleasure and beautiful experience
```html
<!--
Note that we are using a combination of styles and ngStyle inside theme object,
having `height.px` receiving a number and `background-color` receiving a HEX Color
-->
<div style="background: #FF0001; padding: 10px;">
<ngx-skeleton-loader
count="5"
[theme]="{
'height.px': 50,
'background-color': '#992929'
}"
></ngx-skeleton-loader>
</div>
```
### ⚠️ This is here only as a documentation, but it's not encouraged to be used. Please consider use it with caution ⚠️
Also, you can use CSS to add theme styles into your component. However, there are some implications:
- You're using `:host` in your stylesheet, which means **you are aware of any possible problem `:host` can create for your app at that level since it's based on [`:host` DOM style scoping](https://developer.mozilla.org/en-US/docs/Web/CSS/:host)**
- You're adding stylesheet based on `<ngx-skeleton-loader>` internal classes. It means that **class naming changes on module's side will be breaking changes for your application as well**.
As an example, your Component file is like this
```typescript
import { Component } from '@angular/core';
@Component({
selector: 'my-ngx-skeleton-loader-with-theming',
templateUrl: './my-ngx-skeleton-loader-with-theming.component.html',
styleUrls: ['./my-ngx-skeleton-loader-with-theming.component.css'],
})
export class MyNGXSkeletonLoaderWithThemingComponent {
/* ... code goes here*/
}
```
And your component HTML code is
```html
<!--
file: my-ngx-skeleton-loader-with-theming.component.html
As an example, it's not using themes via [theme] attributes.
-->
<ngx-skeleton-loader count="5" animation="pulse"></ngx-skeleton-loader>
```
You can apply theme changes in our stylesheet. At the end it will be
```css
/* file: `my-ngx-skeleton-loader-with-theming.component.css`
*
* You can find more details about `:host` at
* Angular Component Style Docs https://angular.io/guide/component-styles#host
*/
:host >>> ngx-skeleton-loader .skeleton-loader {
border-radius: 5px;
height: 50px;
background-color: #992929;
border: 1px solid white;
}
```
> You should change the styles on the skeleton wrapper element in case you need to change the background color. You can check the code details in the [Stackblitz Live Demo Link](https://stackblitz.com/edit/ngx-skeleton-loader-sample?file=app%2Fapp.component.html) or check it out a content load simulation [in this Stackblitz Live Demo Link](https://stackblitz.com/edit/ngx-skeleton-loader-user-card-component-sample?file=app%2Fapp.component.html)
