If you've encountered the error "Webpack Error In CommonsChunkPlugin While Running In Normal Mode: It's Not Allowed To Use A Non-Entry Chunk," don't worry, you're not alone. This error can be a bit confusing at first, but fear not, we're here to help you understand what it means and how you can resolve it.
When you see this error message, it typically means that there's an issue with how Webpack is configured to handle your entry chunks. In Webpack, an entry chunk is the starting point where your application begins executing. The CommonsChunkPlugin is a plugin that helps optimize your webpack build by extracting common dependencies into a shared chunk.
So why does this error occur? Essentially, it's telling you that you're trying to use a chunk that is not the entry point of your application. In normal mode, Webpack expects that all the chunks it processes are entry chunks, as these are the primary starting points for your application.
To address this error, you'll need to review your Webpack configuration to ensure that you are correctly specifying the entry points for your application.
One common mistake that can lead to this error is incorrectly defining the entry point in your Webpack configuration. Make sure that your entry points are set up correctly and that you're not inadvertently using a non-entry chunk in your configuration.
Another thing to check is whether you have correctly configured the CommonsChunkPlugin in your Webpack setup. Ensure that the plugin is configured to extract common dependencies only from the entry chunks and not from any other chunks in your application.
Additionally, check if you have any circular dependencies in your modules, as this can also trigger the error. Circular dependencies occur when two or more modules depend on each other, causing a loop that Webpack can't resolve.
To troubleshoot the issue further, you can try running Webpack in verbose mode to get more detailed output about the build process. This can help you pinpoint the exact source of the error and facilitate the debugging process.
Once you've identified and fixed the root cause of the error, you should be able to run Webpack successfully in normal mode without encountering the "Webpack Error In CommonsChunkPlugin While Running In Normal Mode: It's Not Allowed To Use A Non-Entry Chunk" message.
In conclusion, this error in Webpack usually stems from misconfigurations related to entry chunks and the CommonsChunkPlugin. By carefully reviewing your Webpack setup, fixing any misconfigurations, and running Webpack in verbose mode for debugging, you should be able to resolve this issue and get back to building your application seamlessly. Keep tinkering, and happy coding!
