There are several ways you can optimize webpack build memory usage:

  1. Use the latest version of webpack: Make sure you are using the latest version of webpack as newer versions often come with performance improvements and optimizations.
  2. Increase node's memory limit: You can increase the memory limit for Node.js by setting the NODE_OPTIONS environment variable. This can help webpack process larger projects without running out of memory.
  3. Use webpack's performance hints: Set performance hints in your webpack configuration to alert you when a build is taking up too much memory. This can help you identify and fix performance issues early.
  4. Use code splitting: Splitting your code into smaller chunks can reduce the amount of memory needed to build and load your application. This can also improve loading times for your users.
  5. Limit the number of loaders: Try to limit the number of loaders you use in your webpack configuration, as each loader adds overhead to the build process. Consider using more efficient loaders or combining multiple loaders into a single one.
  6. Use the ModuleConcatenationPlugin: This plugin can help reduce the memory usage of your webpack builds by concatenating modules into a single function scope, reducing the overall size of your bundle.
  7. Use DLLs: DLLs (Dynamic Link Libraries) can help reduce the memory usage of your webpack builds by pre-compiling common dependencies into separate bundles that can be cached and reused across builds.


By following these tips and optimizing your webpack configuration, you can reduce memory usage and improve the performance of your webpack builds.
