Angular 8+ Cloud Uploads Library

This project was generated with Angular CLI version 8.0.0.

To be used in conjuction with Comdominios.

Introduction

This project is an Angular library for handling secure direct to cloud uploads that are managed by the Condominios project. At CoTag Media we use it to handle all of our file ingestion as it:

• takes the load away from our API servers
• allows us to support hybrid cloud models
• works seamlessly with AWS Lambda and Google Cloud Functions

Effectively this project takes blob or file objects in the browser and

• Manages an upload queue with pause, resume and progress for each upload
• Supports configuring individual upload parallelism and the number of simultaneous uploads
• All files are hashed in webworkers before upload for data integrity
• Communicates with Condominios to obtain signed requests for the uploads

Usage

1. Optionally bootstrap MD5_WORKER_BASE - this allows you to customise the path of the MD5 worker
2. Bootstrap the MD5Workers - these perform the hashing in webworkers and should only be instansitated once
3. In the components you wish to perform uploads, inject your Http service and the MD5Workers
4. Import UploadManager and the storage providers you wish to use Amazon, Google, Azure, OpenStack
5. Add the providers to the upload manager: UploadManager.addProvider(Amazon);

You can now use the manager

this.manager = new UploadManager(http, '/uploads', workers);
this.manager.autoStart = true;

// ...

// Add files to the upload manager
// Files is an array of Blobs or Files -> https://developer.mozilla.org/en/docs/Web/API/File
this.manager.upload(files);

Development server
