React components Import & Export


In this tutorial you will learn how to create a working file upload component with react from scratch using no dependencies other than react itself. Also, we will start by building a server we can upload files to using nodejs and express. We will walk through the full full-stack process to make sure you end up with a working system. Before we can have a react app upload anything, we need to have a server we can upload to, right? In this tutorial, we are going to implement a file upload server using node. Next, open the command line pointing at the server directory and initialize a new npm-project using the. For the server, we will also need two JavaScript files. Create the following files in the project directory:. The first one is obviously express. To install express, you can use this command inside of the server directory:. Because we want to access the API from a react application that is probably served from another origin, the server needs to allow cross-origin requests. Therefore we are going to use a simple module called CORS. To install it, type:. Also, express itself is not very good at understanding forms. The library "formidable" does this and is quite easy to use. Install formidable using this command:. First, we need to create a basic express server in the server. This part looks always the same and consists of only 3 lines. As this is using a relative path, make sure you have opened the terminal at the server directory. To be able to access our API from a react application with a different origin, we need to enable cors. To do so, we first need to require CORS. Let's start implementing the upload functionality. We will place it into the upload. After that, we need to export the callback function, we are using in our server. This callback gives us a request-object reqthat stores information about the request that hit the route. We then register callbacks on that form. The first callback is called for every file in the form:. The uploaded files are stored in a temporary directory somewhere on your machine. To do something with them, you can copy them from there using the node.

Now compare MyApp. You will notice that it is almost the same as index. The first thing you need to do is to import React and Component from react. The reason we are importing react is the file contains JSX code. Almost every file containing functional component needs to import react to convert JSX code into vanilla JavaScript. To import external files, use the relative path. The export statement will make your functional component called MyApp available to other files in your application. It works okay with react and react-dom as these are third party modules here but when you have to import your defined components, use the relative path. Import statement assumes that you are importing a JavaScript. You can remove the. As your project gets more and more complex, it is very important to have a good organizational structure.

You need to define a structure that works best for you. Before moving on to the next lesson, try changing paths a little bit, or change a file name, or move the file to a different location to see what you need to fix to keep everything working.
