file-fire

Simple way to upload and download files from Firebase Storage.

---

Install

bower install file-fire --save

<file-fire>

An element that uploads files and provides download url from Firebase Storage. For images, it can resize and provide a placeholder as well.

After resizing, it can also generate 2x 3x image sizes. This is determined by the max-scale and scale-step properties. Some examples:

1. max-scale of 3 and scale-step of 1 will generate 1x, 2x and 3x images.
2. max-scale of 2 and scale-step of 0.5 will generate 1x, 1.5x and 2x images.

It can also fetch images from elsewhere (such as a twitter profile image) and upload that to your Firebase Storage.

<firebase-app
  name="demo"
  api-key="AIzaSyACU-9dEBSmlEq8iwfuDCPCWU81UNDytuQ"
  auth-domain="convoofire.firebaseapp.com"
  database-url="https://convoofire.firebaseio.com"
  storage-bucket="convoofire.appspot.com"
  >
</firebase-app>
<file-fire
  app-name="demo"
  path="/remote/file"
  src-url="https://pbs.twimg.com/profile_images/741290730170122240/abfazODg_400x400.jpg"
  progress="{{remoteProgress}}"
  download-url="{{downloadRemoteUrl}}"
  max-scale="3"
  resize-height="50"
  resize-width="50"
  placeholder="{{remotePlaceholder}}"
></file-fire>

<file-fire-drop>

An enhanced version of <file-fire> that allows dragging and dropping a file. This element can have contents that are displayed unless a file is dragged over it.

<file-fire-drop
  app-name="demo"
  path="/u/test.png"
  over-write
  progress="{{progress}}"
  placeholder="{{base64}}"
  files="{{images}}"
>
This text will be visible unless you hover over it while dragging a file</br>

</file-fire-drop>

<file-fire-fetch>

An element that retrieves the download url from the file storage path in Firebase Storage.

<firebase-app
  name="demo"
  api-key="AIzaSyACU-9dEBSmlEq8iwfuDCPCWU81UNDytuQ"
  auth-domain="convoofire.firebaseapp.com"
  database-url="https://convoofire.firebaseio.com"
  storage-bucket="convoofire.appspot.com"
  >
</firebase-app>
<file-fire-fetch
  app-name="demo"
  path="/my/path/to/file.jpg"
  file="{{myFile}}"
  file-url="{{myFileURL}}"
></file-fire-fetch>

Dependencies

Element dependencies are managed via Bower. You can install that via:

npm install -g bower

Then, go ahead and download the element's dependencies:

bower install

Playing With Your Element

If you wish to work on your element in isolation, we recommend that you use Polyserve to keep your element's bower dependencies in line. You can install it via:

npm install -g polyserve

And you can run it via:

polyserve

Once running, you can preview your element at http://localhost:8080/components/image-fire/, where image-fire is the name of the directory containing it.

Testing Your Element

Simply navigate to the /test directory of your element to run its tests. If you are using Polyserve: http://localhost:8080/components/image-fire/test/

web-component-tester

The tests are compatible with web-component-tester. Install it via:

npm install -g web-component-tester

Then, you can run your tests on all of your local browsers via:

wct

WCT Tips

wct -l chrome will only run tests in chrome.

wct -p will keep the browsers alive after test runs (refresh to re-run).

wct test/some-file.html will test only the files you specify.

Yeoman support

If you'd like to use Yeoman to scaffold your element that's possible. The official generator-polymer generator has a seed subgenerator.
