Webpack 5 Migration

Starting in Nx 13, we only support Webpack 5, which is automatically enabled for all workspaces.

Workspaces with custom webpack configuration should make sure that all their plugins and loaders are compatible with Webpack 5. For additional help on the migration, check out Webpack's "To v5 from v4" guide.

Nx 12 is the last Nx version to support Webpack 4 so if you cannot upgrade to Webpack 5 then you may stay on this version, but we highly suggest you upgrade as soon as possible to benefit from future patches and features.

Nx 12: Testing Webpack 5 Compatibility

If you are still on Nx 12, you can try out Webpack 5 without upgrading fully to Nx 13.
