Fix for "Cannot find module '/home/myuser/dist/main.js'" Error in Docker Container

[Daethyra]

Issue Description:

When running the 'gpt-crawler' Docker container, I encountered an error stating that the module '/home/myuser/dist/main.js' could not be found. This issue prevented the crawler from starting.

Steps to Reproduce:

1. Clone the 'gpt-crawler' repository.
2. Build the Docker image using the Dockerfile provided in the root directory.
3. Run the Docker container.
4. Observe the error message indicating that '/home/myuser/dist/main.js' is missing.

Diagnostic Steps:

• [x] Checked the contents of the start_xvfb_and_run_cmd.sh script and verified it was executable.
• [x] Ran the script and observed the output, confirming the error.
• [x] Reviewed the package.json file and noticed the script "start:prod": "node dist/main.js".
• [x] Checked the Dockerfile and noticed the multi-stage build process.
• [x] Encountered an error during the build process: sh: 1: tsc: not found, indicating TypeScript (tsc) was not installed or not found in the PATH in the Docker container.
• [x] Realized the need to update the file path in package.json to point to the correct location of main.js.

Solution:

• Updated the start:prod script in package.json from "start:prod": "node dist/main.js" to "start:prod": "node dist/src/main.js".
• Rebuilt the Docker image with the updated package.json.
• Ran the Docker container with the new image.
• Confirmed that the crawler started successfully and began crawling the default website.

Suggested Changes:

• Update the package.json file to correct the path in the start:prod script.
• Ensure that the Dockerfile and associated scripts are set up to correctly locate and execute main.js.
• Update documentation if necessary to reflect these changes and assist future users in setting up the crawler.

Proposed Solution in Detail:

In order to address the issue and ensure the proper functioning of the 'gpt-crawler' in a Docker environment, the following changes were made:

1. Modification in package.json:

   • Updated the start:prod script to correctly reference the main JavaScript file generated by TypeScript. The original script was "start:prod": "node dist/main.js", which was incorrect as the main.js file is located in the dist/src directory after the TypeScript compilation. The updated script is "start:prod": "node dist/src/main.js".
   • This change ensures that when the Docker container starts, it correctly locates and executes the main JavaScript file.

2. Dockerfile Adjustments:

   • The Dockerfile used for this fix was the one located in the root directory of the 'gpt-crawler' repository.
   • During the Docker build process, an error was encountered indicating that TypeScript (tsc) was not found. This was resolved by ensuring that TypeScript is installed and correctly set up in the Docker environment.
   • The multi-stage build process in the Dockerfile was reviewed and retained as it efficiently separates the build and runtime environments, reducing the final image size.

3. Testing the Solution:

   • After making the above changes, the Docker image was rebuilt to incorporate these modifications.
   • The rebuilt Docker image was then run, and it was confirmed that the crawler successfully started and began crawling the default website without encountering the previous error.

4. Pushing Changes to Forked Repository:

   • These changes have been committed and pushed to my fork of the 'gpt-crawler' repository. This includes the updated package.json and any other relevant modifications made to ensure the functionality of the crawler in a Docker environment.
   • The forked repository can be reviewed for a detailed view of all changes made.

Additional Notes:

• The Dockerfile in the 'containerapp' directory was not used for this fix. It might serve a different purpose and should be reviewed separately.
• Consider adding more detailed error handling and logging for easier troubleshooting in the future.

for those the above solution does not work like me, i get the same error but the path for main.js is correct, i can check it in docker container files. i solved it by changing the "End of Line Sequence" of the file start.sh( it is my entry point in dockerfile) from CRLF to LF, and rebuild the image and wow the error is gone
