Webpack Error: Conflict - Multiple Assets Emit Different Content to 'index.html'

This error occurs when multiple assets emit different content to the same filename, specifically 'index.html'.

In webpack, assets are files that are generated during the build process, such as JavaScript files, CSS files, or images. Each asset should have a unique filename to avoid conflicts.

When multiple assets emit different content to the same filename, it means that two or more assets are trying to generate a file with the same name, in this case, 'index.html'. This can happen if you have multiple entry points or if different plugins or loaders are generating the same file.

To resolve this conflict, you need to ensure that each asset has a unique filename. You can do this by configuring your webpack build correctly. Here are a few possible solutions:

1. Check your webpack configuration and make sure that you don't have multiple entry points that generate the same file. If you have multiple entry points, each should have its own output filename.

2. If you are using plugins or loaders that generate files, check their configurations and make sure that they are not conflicting with each other. For example, if you have multiple plugins generating HTML files, ensure that they are generating files with different names.

3. If you are using a template file for generating the HTML, make sure that the template file itself has a unique name. Sometimes, conflicts can occur if the template file is named 'index.html' and multiple plugins or loaders are trying to use it.

By resolving the conflict and ensuring that each asset has a unique filename, you should be able to fix the 'Conflict: Multiple assets emit different content to the same filename index.html' error in webpack.
