ng-partial-loader is an Angular library that fills unresolved async content by simple partial loader

Demo available @ https://cagcak.github.io/ng-partial-loader
StackBlitz available @ https://stackblitz.com/edit/ng-partial-loader

• Installation
• Usage

To add ng-partial-loader library to your package.json use the following command.

npm install ng-partial-loader --save

or

yarn add ng-partial-loader

After installation completed, define NgPartialLoaderModule to your module scope to use

import { NgModule } from '@angular/core';
import { NgPartialLoaderModule } from 'ng-partial-loader';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [NgPartialLoaderModule],
  bootstrap: [AppComponent],
})
export class AppModule {}

then in angular.json define default loaders asset location to style bundle if it will be used

...
{
  ...
"architect": {
  "build": {
    ...
    "options": {
      ...
      "assets": [
        ...
        {
          "glob": "**/*",
          "input": "node_modules/ng-partial-loader/src/assets",
          "output": "./assets"
        }
      ],
    }
    ...
  }
}

ng-partial-loader requires a minimal directive definition to make loader available as in needed an alternative content with a boolean value to hide/show options as dynamically.

isHttpRequestResolved: boolean = false;

<div [ngPartialLoader]="isHttpRequestResolved">
  <span>This content will be available if isHttpRequestResolved is true</span>

  <div id="ng-partial-loader-uuid">
    this dynamic loader element added to dom when isHttpRequestResolved is true
  </div>
</div>

ng-partial-loader has an NgPartialLoaderOptions named model

• path: loader graph or vector path with forward slashes, ex: '/resources/images/loaders/'
• fallback: fallbak loader file with extension, ex: 'loading.png'
• customLoader: application specific loader, ex: 'loader.svg'
• minHeight: minimum height for loader scope
• loader: library based loader option, ex: 'blocks' | 'dual-ring' | ... etc

If there is not any option defined, the directive will have default animated cube loader.

Below demonstrates how to pass options

<div
  [ngPartialLoader]="isHttpRequestResolved"
  [loaderOptions]="{
    path: '/assets/my-images/',
    customLoader: 'bullets.gif'
  }"
>
  ...
</div>

<div [ngPartialLoader]="isHttpRequestResolved" [loaderOptions]="{ loader: 'ripple' }">...</div>
