CORS when deployed on VPS

I deployed novu (docker file from docker/community folder) on VPS to use it with my next.js app. And I faced the problem of CORS. Do I need make some changes in docker file to solve CORS? Do I need make some changes on VPS? Or I need find solution on the side of my app?

Hi @Kh. M-S., I'm an AI assistant for Novu. While a team member reviews this question, I'll see if I can find relevant sources for your question. ----------------------------- While I generate an answer, here are some sources that might be helpful: * Deploy with Docker * MacOS/Linux * AWS * API Overview ----------------------------- Answer To resolve the CORS issues you're experiencing with your Novu deployment on a VPS, you should consider updating the CORS configuration in your server setup. This involves specifying the allowed origins that should have access to your Novu instance. This can typically be done within your application code or server configuration, not directly within the Docker file itself. For a typical setup using Node.js, which might be similar to your Next.js app's backend, you would set the CORS policy to allow requests from the specific domains that your frontend application uses. Here’s an example of how you might configure CORS in a Node.js environment:
const cors = require('cors');
const app = require('express')();

app.use(cors({
origin: 'http://yourfrontenddomain.com'
}));

// your other app setup and routes
const cors = require('cors');
const app = require('express')();

app.use(cors({
origin: 'http://yourfrontenddomain.com'
}));

// your other app setup and routes
Replace 'http://yourfrontenddomain.com' with the actual URL of your Next.js application. This setup allows your Next.js frontend to communicate with your Novu backend without facing CORS issues. Additionally, ensure that your VPS and any reverse proxy configurations (like Nginx or Apache) are not overriding these headers or settings. Sometimes, server configurations can affect how CORS headers are handled, so it's important to ensure consistency across your deployment environment. If you're managing CORS within a Dockerized Novu setup, you might need to ensure that your Novu service is correctly configured to handle incoming requests as per the CORS policy you define in your application code. For more detailed and specific guidance, you might want to refer to the official Novu documentation or community resources, as they might have specific instructions or examples that could help in your scenario.
