Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Demo

Check out the interactive demo on StackBlitz.

Installation

Install ngx-loading via NPM, using the command below.

NPM

npm install --save ngx-loading

NOTE: Version 8 of this package requires Angular 8 as a dependency. If you are using Angular 7, please install version 7. For Angular 6, please install version 3 and for Angular 4 / 5, please install version 2.0.1 e.g.

npm install --save [email protected]

Getting started

Import the NgxLoadingModule in your root application module:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { CoreModule } from './core/core.module';
import { NgxLoadingModule } from 'ngx-loading';

@NgModule({
  //...
  imports: [
    //...
    NgxLoadingModule.forRoot({})
  ],
  //...
})
export class AppModule { }

You must create a boolean variable (e.g. loading below) that is accessible from the component which will contain ngx-loading. This boolean is used as an input into ngx-loading, and will determine when the loading spinner is visible.

import { Component, OnInit } from '@angular/core';

@Component({
    //...
})
export class AppComponent implements OnInit {
    //...
    public loading = false;

    constructor(private authService: AuthService) { }

    ngOnInit() { }

    Login() {
        this.loading = true;
        this.authService.login(this.email, this.password)
            .subscribe(res => {
                this.loading = false;
                //...
            }, err => {
                this.loading = false;
                //...
            });
    }
}

Next, add the ngx-loading component selector to your application component's template. Set the [show] input variable of ngx-loading to point to your boolean, which will determine when ngx-loading is visible. Optionally set the [config] input variable of ngx-loading to setup custom configuration options. If the [config] input variable is not set, the globally configured configuration will be used, if set. If no config options are set, the ngx-loading default config options will be used. See Config options for further information.

You can also optionally define a [template] input variable, which can be used to inject your own custom templates into the component.

NOTE: ngx-loading will fill the entirety of its parent component. If you wish for ngx-loading to only fill a specific element within your component, ensure that ngx-loading is a child element of that element, and that the containing element has its position attribute set to relative.

<div class="my-container">
    <ng-template #customLoadingTemplate>
        <div class="custom-class">
            <h3>
                Loading...
            </h3>
            <button (click)="showAlert()">
                Click me!
            </button>
        </div>
    </ng-template>

    <ngx-loading [show]="loading" [config]="{ backdropBorderRadius: '3px' }" [template]="customLoadingTemplate"></ngx-loading>
    //...
</div>

Input parameters

| Input | Required | Details | | ---- | ---- | ---- | | show | Required | A boolean, which will determine when ngx-loading is visible. | | config | Optional | A set of configuration options for ngx-loading. If this is not specified, the globally configured configuration will be used, if set. If no config options are set, the ngx-loading default config options will be used. See Config options. | | template | Optional | A TemplateRef, which will be displayed within the ngx-loading component. Use this to inject your own custom templates into the component.

Config options

| Option | Required | Default | Details | | ---- | ---- | ---- | ---- | | animationType | Optional | ngxLoadingAnimationTypes.threeBounce | The animation to be used within ngx-loading. Use the ngxLoadingAnimationTypes constant to select valid options. | | backdropBorderRadius | Optional | 0 | The border-radius to be applied to the ngx-loading backdrop, e.g. '14px'. | | backdropBackgroundColour | Optional | rgba(0, 0, 0, 0.3) | The background-color to be applied to the ngx-loading backdrop, e.g. 'rgba(255, 255, 255, 0.2)'. | | fullScreenBackdrop | Optional | false | Set to true to make the backdrop full screen, with the loading animation centered in the middle of the screen. | | primaryColour | Optional | #ffffff | The primary colour, which will be applied to the ngx-loading animation. | | secondaryColour | Optional | #ffffff | The secondary colour, which will be applied to the ngx-loading animation (where appropriate). | | tertiaryColour | Optional | #ffffff | The tertiary colour, which will be applied to the ngx-loading animation (where appropriate). |

Config options can be set globally (using the .forRoot() module import statement), as well as being passed into each ngx-loading instance, if required. Config options that are passed into an ngx-loading element will override any custom global config options that have been set. A combination of the two can be used together if appropriate. If no config is set, the default ngx-loading config options will be used. Please see below for an example custom configuration setup, using both global and local configurations.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { CoreModule } from './core/core.module';
import { NgxLoadingModule, ngxLoadingAnimationTypes } from 'ngx-loading';

@NgModule({
  //...
  imports: [
    //...
    NgxLoadingModule.forRoot({
        animationType: ngxLoadingAnimationTypes.wanderingCubes,
        backdropBackgroundColour: 'rgba(0,0,0,0.1)', 
        backdropBorderRadius: '4px',
        primaryColour: '#ffffff', 
        secondaryColour: '#ffffff', 
        tertiaryColour: '#ffffff'
    })
  ],
  //...
})
export class AppModule { }
<div class="my-container">
    <ng-template #customLoadingTemplate>
        <div class="custom-class">
            <h3>
                Loading...
            </h3>
            <button (click)="showAlert()">
                Click me!
            </button>
        </div>
    </ng-template>

    <ngx-loading [show]="loading" [config]="{ animationType: ngxLoadingAnimationTypes.rectangleBounce,
        backdropBackgroundColour: 'rgba(255,255,255,0.3)', backdropBorderRadius: '10px',
        primaryColour: '#ffffff', secondaryColour: '#ffffff', tertiaryColour: '#ffffff' }" [template]="customLoadingTemplate"></ngx-loading>
    //...
</div>
