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 🙏

AngularFire Storage Wrapper

Angular class which wraps AngularFire Storage and provides methods to upload multiple files simultaneously while keeping track of their progress.

AngularFire (https://github.com/angular/angularfire) is the official Angular Library for Firebase.

AngularFire Storage provides a simple interface to upload/download files to your Firebase storage bucket.

@Component({s
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
    ngFireStorageWrapper: AngularfireStorageWrapper; /* this is the wrapper */
    
    constructor(private angularFireStorage: AngularFireStorage) {
    
        /* initialize wrapper by giving it the AngularFireStorage instance */
        this.ngFireStorageWrapper = new AngularfireStorageWrapper(angularFireStorage);
    }
  
    uploadFiles(files: File[]): void  {
       /* create a list of paths where the files will be saved on the firebase storage bucket,
        * the paths must be in the same order as the files */
       const paths: string[] = [];
   
       files.forEach(file => {
         paths.push(`${file.name}`);
       }); 

        /* create GroupedUploadData object, the upload will start as soon as this object is created */
        const groupedUploadData: GroupedUploadData = this.ngFireStorageWrapper.uploadMultipleFiles(
          paths, files, [], { cacheControl: 'public, max-age=15552000' });

        groupedUploadData.uploadPercentageGrouped$.pipe(
          takeWhile(percentage => percentage < 100, true),
        ).subscribe(percentage => console.log(percentage));  /* log percentage */
    }   

}

Using the library

Import the library in any Angular application by running:

$ npm install angularfire-storage-wrapper --save

and then from your Angular AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

// Import the library module
import {AngularfireStorageWrapperModule} from 'angularfire-storage-wrapper';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,

    // Specify AngularfireStorageWrapperModule library as an import
    AngularfireStorageWrapperModule
  ],
  providers: [],
  bootstrap: [ AppComponent ]
})
export class AppModule { }

Once the library is imported, you can use it in your Angular application:
