12/13/2023 0 Comments Bitnami mean node app forever![]() As the ports are different, they are considered different origins by the browser.īut in production, we don’t need a CORS mechanism to access the resources as we don’t use a development server for React. We need to request resources from one origin to a different one. We use CORS because React and Node.js are running on two different ports in the development environment. But modern web browsers enforce the same origin policy as part of their security model. So make sure you handle the exceptions properly.Ĭross-Origin Resource Sharing is a mechanism that allows requesting resources from a different domain, sub-domain, port, or protocol. ![]() ![]() You can find it under the resource section.Īlso, remember that Node.js apps crash when they encounter an uncaught exception. There is an article explaining Node.js logging with best practices that I wrote. But it’s essential to configure a logger before deploying the application. You should follow some best practices before moving your app to production.Īs this is a demo app, I didn’t include a logger to this purposely. In there, the base URL will look like this: const baseUrl: string = " So change the base URL as follows: const baseUrl: string = "/api" Backend In my application, you can find the API.ts file in the src folder. We need to change the base URL as our express server is no longer going to be reachable through localhost:3001 We can access the resources by only using the prefix /api as we are serving from the same machine. Code ModificationsĪs the first step, we need to do some small code modifications to the current working app. Let’s jump into the step-by-step tutorial for deploying our application. Let’s discuss what our application looks like in the production environment.įolder Structure (Image by Author) Deploying the App I hope now you have a clear idea about Nginx. Security: It can prevent DDoS attacks, IP blacklisting and whitelisting, etc.Encryption and compression are two heavy computed processes that Node.js is not good at. So the information site users receive and send will be protected. Implement SSL/TLS: This allows for configuring secure HTTPS protocol with SSL.Error handling: The application can display proper error pages if it crashes.Also, it can configure to run multiple backends on the same server. Act as a Load Balancer: This help to allocate resources and dispatch traffic across multiple servers, allowing to scale out very efficiently.Act as a Reverse proxy: It forwards the client requests to an appropriate server and vice versa.Caching: This provides a cache for both static and dynamic content.This enables better utilization of the OS and hardware resources. Low memory and resource consumption: This can handle many concurrent user requests while consuming a very low memory of around 2.5MB.It also comes with an inbuilt gzip compressor. Better serving static content: It can serve them lightning-fast, with minimal processor load.Some reasons why you should consider using Nginx: Also, this can be used as a reverse proxy, load balancer, mail proxy, and HTTP cache. Nginx, pronounced as ‘engine ex,’ is a free and open source feature-rich web server. But on the other hand, Nginx is like a little beast. The famous Unix philosophy is “Write programs that do one thing and do it well.” Although our Node express backend can serve the static files, it is not specially made for that. Wait! What is this Nginx? Can’t we directly serve the app using our backend? Let me clarify the things for you. We create an optimised production build and serve it using the Nginx server. But in production, we don’t use this development server. We develop the React application with an underground development server that serves the app. MERN Application in the local development environment (image by author)Īs I show in the diagram, this is what a full stack application normally looks like in the development environment.
