Steps to reproduce

Description

I am experiencing an issue where changes made to the frontend code are not automatically reflecting in the local deployment when using npm run dev. This issue occurs even after saving the modified files.
I followed all the steps to start the local deployment as mentioned in the Docs

Steps to Reproduce

1. Start the frontend and backend using npm run dev as per the documentation.
2. Make changes to any frontend file (e.g., modify text in a component).
3. Save the file.

✔️ Expected Behavior

The changes should automatically reflect in the local deployment when hit save

❌ Actual Behavior

Changes are not appearing in the local deployment even when I restart the deployment or manually refresh the browser.

It sounds like you're encountering issues with hot reloading not reflecting changes in your local deployment when using npm run dev. Here are some targeted steps to troubleshoot and hopefully resolve this issue:

1. Ensure Docker Volume Mapping is Correct: If you're using Docker, verify that your local development directory is correctly mapped to the container's directory. This is crucial for changes to be detected and reflected inside the Docker container. The command should look something like this, adjusting for your specific paths:

   docker run -it -p 3000:3000 -v $(pwd):/app dify-web
   

   This ensures that your current working directory ($(pwd)) is mapped to the /app directory inside the container.

2. Check for Syntax Errors: Sometimes, syntax errors can prevent hot reloading from functioning properly. Make sure there are no such errors in your code.

3. File Watching in Docker: Docker's file watching might not work as expected in all environments. Ensure your IDE or editor is saving files in a way that Docker can detect changes. Some editors' "safe write" features might need to be disabled.

4. Browser Cache: Aggressive caching by the browser can sometimes cause this issue. Try using your browser's developer tools to disable cache or use an incognito window to test your changes.

5. Review Custom Server Configurations: If you've customized the Next.js server configuration, ensure these changes aren't interfering with hot reloading.

6. .env.local File Configuration: Double-check your .env.local file configuration. Incorrect settings here can lead to the behavior you're experiencing.

These steps are designed to address common issues with hot reloading in a Docker environment and with Next.js projects. If you've gone through these and the problem persists, it might be worth consulting the Next.js community for more specific advice, given the project's reliance on Next.js for frontend development.

Do you mean the hot reload feature in local dev development?

I am pretty sure, the changes will take effect in our dev environment otherwise we will not be able to code as well.

Addintionally, If you need to make changes to see if it's worked. You just need to follow the instructions above this section.
