Reacticus

Components and helpers to use with React

Upload input, simpler & prettier

Usually you do:

<form ...>
  ...
  <input type="file" ... />
  ...
  <input type="submit" value="Do submit"/>
</form>

and you get a pop-up, an ugly input field in your pretty form, and the file uploads with the form submittion.

If you only want to upload a file, without the standar form funcionality, just a button that when the file is selected it automatically uploads and lets you do your JS magic with Reacticus you can do:

import { UploadButton } from "reacticus";

...

<UploadButton className="btn btn-sm" onFileSelected={fileList => ...}>
  <span className="glyphicon glyphicon-search" aria-hidden="true"></span> Upload a file!
</UploadButton>

In this example we're using some Bootstrap (http://getbootstrap.com/) helpers to give some style to our component, but it's totally optional. The UploadButton component receives any property that the standard HTML5 button component can use, and in its body you can do anything you'd do in the button body. The only thing you have to know is that when a user clicks the button it will pop the file selection window (so you cannot override the onClick property) and when the user accepts the selection it will trigger the onFileSelected giving you a FileList (https://developer.mozilla.org/en-US/docs/Web/API/FileList) object as param, and you can do whatever you want with it.
