ember-cli-file-saver v2.0.0

Ember-cli-file-saver

Provides support to save binary file from an API for an Ember CLI application.

Installation

Install the ember-cli addon in your ember-cli project:

$ ember install ember-cli-file-saver

This should also automatically:

• add an NPM dependency to FileSaver.
• add a transport layer for jQuery to handle arraybuffer and blob dataType.

Note that to make this new transport layer works nicely with ember-data it is necessary to make your adapter extend the adapter-arraybuffer-mixin mixin and pass either arraybuffer:true or blob:true as an AJAX option, otherwise ember-data will try to interpret the response as JSON.

Usage

ES6 Import

This addon provides the ability to import FileSaver as an ES6 module.

import FileSaver from 'file-saver';

Adapter Mixin for ArrayBuffer / Blob response

import ActiveModelAdapter from 'active-model-adapter';
import AdapterArrayBufferMixin from 'ember-cli-file-saver/mixins/adapter-arraybuffer-mixin';

const ApplicationAdapter = ActiveModelAdapter.extend(AdapterArrayBufferMixin);

ApplicationAdapter.reopen({
 // 
});

export default ApplicationAdapter;

Download from a component

import Ember from 'ember';
import FileSaverMixin from 'ember-cli-file-saver/mixins/file-saver';

const { Component, computed } = Ember;

export default Component.extend(FileSaverMixin, {

  tagName: 'button',

  click() {
    this.get('ajax').request(this.get('downloadUrl'), {
      method: 'GET',
      dataType: 'arraybuffer', // or 'blob'
      processData: false
    })
    .then((content) => this.saveFileAs(this.get('filename'), content, this.get('contentType')));
  }
});

Using from a model

This works well with the ember-api-actions project:

// models/invoice.js

import Ember from 'ember';
import DS from 'ember-data';
import { memberAction } from 'ember-api-actions';

const { computed } = Ember;
const { belongsTo, attr, Model } = DS;

export default Model.extend({

  invoiceNumber: attr('number'),

  download: memberAction({ path: 'download', type: 'GET', ajaxOptions: { arraybuffer: true } })
});

// in a component

invoiceModel
  .download()
  .then((pdfContent) => this.saveFileAs('invoice.pdf', pdfContent, 'application/pdf'));
