react cloud foundry nginx 404 - Javascript

Introduction

When deploying a React application to Cloud Foundry with Nginx as the web server, you may encounter a 404 error. This error occurs because the URL requested by the browser does not match the route defined in the React application, causing Nginx to return a 404 error.

In this article, we will explore how to resolve the Nginx 404 error when deploying a React application to Cloud Foundry.

Prerequisites

Before we begin, make sure you have the following:

• A Cloud Foundry account
• A React application
• The Cloud Foundry CLI installed

Solution

To resolve the Nginx 404 error, we need to configure the Nginx server to redirect any requests that do not match a route defined in the React application to the index.html file. This can be done by adding a custom nginx.conf file to the root of the application.

Step 1 - Create nginx.conf file

Create a file called nginx.conf in the root of your React application and add the following configuration:

server {
  listen $PORT;
  server_name localhost;

  location / {
    try_files $uri /index.html;
  }
}

Step 2 - Configure manifest.yml

Update the manifest.yml file of your Cloud Foundry application to include the location of the nginx.conf file.

applications:
- name: my-react-app
  buildpacks: 
    - staticfile_buildpack
  path: build/
  command: $HOME/nginx/sbin/nginx -c $HOME/app/nginx.conf -p $HOME/app

Step 3 - Deploy your application

Deploy your React application to Cloud Foundry using the following command:

$ cf push

Conclusion

In this article, we demonstrated how to resolve the Nginx 404 error when deploying a React application to Cloud Foundry with Nginx as the web server. By adding a custom nginx.conf file and configuring the manifest.yml file, we can ensure that any requests that do not match a route defined in the React application are redirected to the index.html file.
