Angular File Saver is an AngularJS service that leverages FileSaver.js and Blob.js to implement the HTML5 W3C saveAs() interface in browsers that do not natively support it

• Angular
• FileSaver.js
• Blob.js

File dist/angular-file-saver.bundle.js contains all required dependencies and grants access to both Blob.js and FileSaver.js polyfills via Blob and SaveAs services.

# Using bower:
$ bower install angular-file-saver

# Using npm:
$ npm install angular-file-saver

• Include ngFileSaver module into your project;
• Pass both FileSaver and Blob services as dependencies;
• Create a Blob object by passing an array with data as the first argument and an object with set of options as the second one: new Blob(['text'], { type: 'text/plain;charset=utf-8' });
• Invoke FileSaver.saveAs with the following arguments:
  • data Blob: a Blob instance;
  • filename String: a custom filename (an extension is optional);
  • disableAutoBOM Boolean: (optional) Disable automatically provided Unicode text encoding hints;
