webpack has a rich plugin interface. Most of the features within webpack itself use this plugin interface. This makes webpack very flexible.
|common-chunks-webpack-plugin||Generates chunks of common modules shared between entry points and splits them into separate bundles (e.g vendor.bundle.js && app.bundle.js)|

webpack uses async I/O and has multiple caching levels. This makes webpack fast and incredibly fast on incremental compilations.
webpack supports ES2015+, CommonJS and AMD modules out of the box. It performs clever static analysis on the AST of your code. It even has an evaluation engine to evaluate simple expressions. This allows you to support most existing libraries out of the box.
webpack allows you to split your codebase into multiple chunks. Chunks are loaded asynchronously at runtime. This reduces the initial loading time.
Most of the time, if webpack is not working correctly for you it is a simple configuration issue.
If you are still having difficulty after looking over your configuration carefully, please post a question to StackOverflow with the webpack tag. Questions that include your webpack.config.js and relevant files are more likely to receive responses.
If you have discovered a bug or have a feature suggestion, feel free to create an issue on Github.
If you create a loader or plugin, please consider open sourcing it, putting it
on npm and following the
You are also welcome to correct any spelling mistakes or any language issues.

Most of the core team members, webpack contributors and contributors in the ecosystem do this open source work in their free time. If you use webpack for a serious task, and you'd like us to invest more time on it, please donate. This project increases your income/productivity too. It makes development and applications faster and it reduces the required bandwidth.
This is how we use the donations:
We had other sources of donations before starting to use OpenCollective (or people that can't donate via OpenCollective). We want to acknowledge these sponsors and backers, but donations were not public and we are not sure of donors want to stay anonymous. So if you want to be in this list, just send a PR.
