/**
|
|
* @module DownloadButton
|
|
* DownloadButton components are an action button used to download data. Both the action text and icon are yielded.
|
|
* * NOTE: when using in an engine, remember to add the 'download' service to its dependencies (in /engine.js) and map to it in /app.js
|
|
* [ember-docs](https://ember-engines.com/docs/services)
|
|
* @example
|
|
* ```js
|
|
* <DownloadButton
|
|
* class="button"
|
|
* @data={{this.data}}
|
|
* @filename={{this.filename}}
|
|
* @mime={{this.mime}}
|
|
* @extension={{this.extension}}
|
|
* @stringify={{true}}
|
|
* >
|
|
* <Icon @name="download" />
|
|
* Download
|
|
* </DownloadButton>
|
|
* ```
|
|
* @param {string} [filename] - name of file that prefixes the ISO timestamp generated at download
|
|
* @param {string} [data] - data to download
|
|
* @param {function} [fetchData] - function that fetches data and returns download content
|
|
* @param {string} [extension='txt'] - file extension, the download service uses this to determine the mimetype
|
|
* @param {boolean} [stringify=false] - argument to stringify the data before passing to the File constructor
|
|
* @param {callback} [onSuccess] - callback from parent to invoke if download is successful
