file-uploader

React JS File Uploader Component

Description

Simple react file upload component with loading throbber. Abstracts the FE loading functionality and invokes a callback function once the file has been already loaded with the appropriate data. This was originally thought for text files. Can accept specific file types if needed

Installation

Install it from npm and include it in your React build process (using Webpack, Browserify, etc).

npm i file-uploader-js

Usage

Import FileUploader in your react component.

import FileUploader from 'file-uploader';

and specify the callback function you want to call when the file is loaded.

While the file is loading, you'll see a loading throbber.

For example:

<FileUploader
  accept=".csv"
  title="Please upload a CSV file"
  titleCss={{ color: "#000", fontFamily: "arial" }}
  uploadedFileCallback={e => {
    this.uploadedCsv(e);
  }}
/>

And then define the callback function

uploadedCsv(fileData) {
    console.log(fileData);
    //Do stuff with the loaded file data
}
