Create react app proxy not working axios

React is a JavaScript library for building powerfull user interfaces. It's developed by Facebook and used by developers worldwide. Create React App is an npm tool to generate React apps without any build configurations for tools such as Webpack or Babel. That doesn't mean these tools are not used but they are just hidden so you can focus on building your React app instead of setting up build environments.

By issuing a few commands you can generate a React app and start building your next idea in time record but if you need to integrate your app with a server framework such as Django in our case we still need to do little configuration so fmcg distributors in iraq can deploy your React app as a static front end for your Django project.

In this How To tutorial we are going to see how to use Create React App with Django to create our Django app front end using React in both development and production environments. We are not going to reinvent the wheel here ,I have previously created a simple product manager api with Django and Django Rest Framework so I'm goint to use it. You can also follow the tutorial to create offerte casette API endpoints.

Putting the React app inside Django root folder is not the end of the problem we still need to tackle these two issues :. In development you don't have any problem running two servers so you can Django and React local developent servers to run both apps. React doesn't have any built in support for sending http requests since it's only a view library not a complete framework so we are going to use axios : a library for sending http requests on the browser.

If you run your app and click on send GET button you should get a response from the Django server with an array of products and other information. In many cases absolute endpoints urls are used which makes this proxy useless so how to overcome this? That's all you can continue developing your web app using Django and React and when you are ready to deploy your app for production you need to change your strategy that's because running two servers in production is not a good approach for many reasons so lets see how to use Django and React in prodction environments :.

Now the next thing is to serve the React app index. Make sure to place any other urls or API endpoints before the catch all pattern so they can continue to work. We have seen how to create a React frontend for Django web apps using Create React App project generator and how to send http requests from React to Django. No 'Access-Control-Allow-Origin' header is present on the requested resource.

CorsMiddleware', 'django.Developers have struggled with CORS for longer than they should. This is because it's a tricky concept to grasp, especially for new developers who are working with third-party APIs from their single-page applications on React, Angular, Vue, etc.

I'll also show you how you can deal with it in general and in a React application. CORS stands for cross-origin resource sharing. Just like HTTPS, it's a protocol that defines some rules for sharing resources from a different origin. We know that modern web apps consist of two key components: a client and a server.

The client requests some data from the server, and the server sends back data as a response. This architecture is popular these days because it allows your back end to be used independently across multiple clients like a web app, a desktop GUI, or a native application. Since the client and server are separate applications, they're usually hosted on different domains. Therefore, your own client that's requesting data from your own server might have different origins.

In another scenario, you might use some third-party services for authentication, analytics, etc. The bottom line is that at some point you are going to interact with an application with a different origin than yours. This means you're going to request resources from the application by making an HTTP request. When you request a resource from an application of a different origin, the web browser uses an SOP same-origin policy protocol to block all your requests to that origin.

Back in the day, this is what made the Internet secure! For instance, a malicious cracker or hacker from xyz. However, this underlying security rule governing browsers does not allow you to request a resource from a different origin.

That's a common use case widely used across web apps today. So what's the solution? CORS enables you to access a resource from a different origin. It is used to override your browser's default behavior due to SOP. So now when your client requests a resource, the response will additionally contain a stamp that tells your browser to allow resource sharing across different origins.

Once your browser identifies this stamp, responses for requests from different origins are allowed to pass through.

If you wish to learn more about it, here's a detailed guide that may help you out. Needless to say, both client and server should be running on different domains or have different origins. We can use React to create a simple client that requests resources from a server. However, we first need a server that can serve as an endpoint the client can request a resource from. Let's create a simple server using Express with some API endpoints.

Inside the directory of your choice, run the following command:. You should now have an empty folder named cors-server.Now everyone knows that I am the laziest developer to not check the docs and featuresso I miss out a lot of great things.

Before anything, I would like to tell that this method applies only for the applications that are created using Create React App and also this proxying works only on the development environment as a development feature and is not available for the production build.

You just need to add a new key to the package. So it is indeed specific for development purposes and not for a production level use. This helps in working with the future, where there's this similar setup and avoids all the crazy localhost hacky architecture for gearing with the environment. You do have other different strategies to go ahead, suggested by the same manual, in case proxy is not flexible enough for your current development purposes:.

One other thing that you will love doing is to start both the client and server in case if it's local to you and is in Node JS or similarconcurrently. As the name suggests, there's an app with the same name too! The package concurrently does what it says, runs multiple commands concurrently. So, with that package in place, you can run both the client and the server with a single command.

The installation obviously goes through the normal Node package installation process using npm. Or you do have the option of installing it globally if it's just you who's working on it, else your team members should have concurrently in their global installation.

It's always recommended to use the package. Also, everyone will be on the same page as you with the development environment. In your package. Now, the only thing you should be adding or modifying is the scripts section. Please look at the following lines.

The first one is the devDependencies section of the above package. You have the following added extra. Now the next one is about how you have modified the scripts section of your package. We have added two more properties to the scriptsone is the server that runs the server side Node JS API application when you run npm run server and the dev that runs both npm run server and npm start in parallel or, with the right word, concurrently.

You can have a quick look at the syntax or usage in the official package page. Yes, this is yet another biggest nightmare for developers, when I have myself written a blog-post that's worth nothing thanks to google about Securing your LocalHost.

Few particular cases where this could be useful are when using the "proxy" feature to proxy requests to an API server when that API server is itself serving HTTPS and also when you are building an application that requires HTTPS even in development environment, like a payment portal or using any of the domains locally that have a. Note that the application will be served using a self-signed certificate, so your web browser will almost definitely display a warning indoor shrimp farming equipment accessing the page.

Obviously this is a pain in the back for most people. It's no more, trust me. First thing we generally try doing is using OpenSSL or some sort and crazy commands to generate a certificate.

Although it's really possible to finish off everything within five minutes, it's definitely a pain for most developers. Chuck that out! Who doesn't like drag-and-drop? Let's use it to fix our certificate problem. Once you use the above method and try to run the server, you'll obviously be faced with this dangerous thing and yeah, I know the feeling :. You'll see something similar. Once you click on View certificate button and you'll have the option to download the certificate - either by dragging it to your desktop in OS X, or by clicking on the Details tab in Windows and clicking Copy to File The below illustration is for macOS users.
