![]() You need to install those dependencies first. Here is the dependenies we need for this tutorial "multer": "~1.3.1" But if you have been experienced with Redux and need to use it, it's quite easy to convert this non-Redux tutorial to Redux style. To make it simple, I don't use Redux in this tutorial. I assume you've already familiar with routing in Node.js, using template engine (such as Handlebars, pug (Jade), etc.), and of course the basic of ReactJS as well as how to compile your ReactJS code. In this tutorial, I'll only focus on how to handle the request containing uploaded files in backend and how to create the React components as well as sending the request to the server. This tutorial shows you how to upload files, either single or multiple, using ReactJS and Node.js as the backend. We use ajax for sending the request to the server. If you use ReactJS as the UI framework and you need to handle multiple files upload, you come to the right place. In addition, you may also want the upload page to support drag and drop functionality, so that users can select the files to be uploaded first on file explorer, drag the files and then drop them on the provided drop zone box. However if you use a UI framework, you need different way to handle it. It's quite easy if you only use HTML file input. If I go back and load Table B again only then are the correct props set.Sometimes you may need to provide a page where users can upload files. Go back to the list, click on Table B, the djsConfig object still has Table A’s id and name props. I click on Table A for the first time, everything works as expected. To explain further, say I have Table A and Table B in a list view, both clickable and they go to their single table view (with react router). Var eventHandlers = ) įrom what I understand the problem is that because dropzone gets initialized only on componentDidMount the props won't be passed down on the parent component's first re-render for some reason. To use this component without React-DOM, use version ^0.6 - from 0.7 on, we need it. There are currently a bunch of good ways to combine and process CSS in React, so I'll leave it to you to choose whatever method is best for you - the component does not automatically load CSS. Please ensure that you also include two required CSS files: node_modules/react-dropzone-component/styles/filepicker.css and node_modules/dropzone/dist/min/. If you are using a fancy boilerplate, you might want to require the lib directly, by using import DropzoneComponent from 'react-dropzone-component/lib/react-dropzone' or require('react-dropzone-component/lib/react-dropzone'). ![]() Many fancy boilerplates are overly fancy and somehow remove those variables. ⚠️ Ensure that React and ReactDOM are global variables, so that they can be reached on window.React or global.React. If you don't want any trouble at all, just add dist/ as a script to your app and use. If you're rolling with ES6/ES2015, feel free to use src/dropzone.js. The package's main entry point is lib/dropzone.js, which gives you all the dropzone components. If you are using one of the many module solutions, you can simply install and require this component like shown below. Optional are a list of event handlers and a configuration object for dropzone.js. The component is initialized with a configuration object. ![]()
