…solution The internal TypeScript path mapping Webpack resolver plugin is used to adjust module resolution during builds via the TypeScript configuration `paths` option. Prior to a build, the `paths` option is now preprocessed to limit the amount of analysis that is needed within each individual module resolution attempt during a build. Since module resolution attempts can occur frequently during a build, this change offers the potential to reduce the total cost of module resolution especially for applications with a large amount of configured path mappings.
