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 🙏

Readme

Background Download plugin for Apache Cordova

API provides an advanced file download functionality that persists beyond app termination, runs in the background and continues even when the user closed/suspended the application. The plugin includes progress updates and primarily designed for long-term transfer operations for resources like video, music, and large images.

Sample usage

    var fileName = "PointerEventsCordovaPlugin.wmv",
        uriString = "http://media.ch9.ms/ch9/8c03/f4fe2512-59e5-4a07-bded-124b06ac8c03/PointerEventsCordovaPlugin.wmv";
    
    // open target file for download
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSystem) {
        fileSystem.root.getFile(fileName, { create: true }, function (targetFile) {
            
            var onSuccess, onError, onProgress; // plugin callbacks to track operation execution status and progress
    
            var downloader = new BackgroundTransfer.BackgroundDownloader();
            // Create a new download operation.
            var download = downloader.createDownload(uriString, targetFile);
            // Start the download and persist the promise to be able to cancel the download.
            app.downloadPromise = download.startAsync().then(onSuccess, onError, onProgress);
        });
    });

Internal vs External (SD card) storage on Android

  • External Storage

    resolve cordova.file.externalDataDirectory directory in runtime

    window.resolveLocalFileSystemURL(cordova.file.externalDataDirectory, function(dirEntry) {
            dirEntry.getFile(fileName, { create: true }, function (targetFile) {
                ...
            })
        }, function(error) {...})

    Note, that device can be without external storage. In this case cordova.file.externalDataDirectory will be null so it should be checked before usage.

  • Internal Storage

    resolve cordova.file.dataDirectory directory in runtime

    window.resolveLocalFileSystemURL(cordova.file.dataDirectory, function(dirEntry) {
            dirEntry.getFile(fileName, { create: true }, function (targetFile) {
                ...
            })
        }, function(error) {...})

Quirks

  • If a download operation was completed when the application was in the background, onSuccess callback is called when the application become active.
  • If a download operation was completed when the application was closed, onSuccess callback is called right after the first startAsync() is called for the same uri, as if the file has been downloaded immediately.
  • A new download operation for the same uri resumes a pending download instead of triggering a new one. If no pending downloads found for the uri specified, a new download is started, the target file will be automatically overwritten once donwload is completed.
  • On Android temporary downloading file is created on external storage (limitation of DownloadManager), so if there is no external storage the downloading will fail.
