-In bundleless mode, since there is no bundling concept, all modules will be externalized.

+Specifies the condition names used to match entry points in the [exports field](https://nodejs.org/api/packages.html#packages_exports) of a package.

 ## resolve.dedupe <RsbuildDocBadge path="/config/resolve/dedupe" text="resolve.dedupe" />
 
 Force Rsbuild to resolve the specified packages from project root, which is useful for deduplicating packages and reducing the bundle size.
 
 ## resolve.extensions <RsbuildDocBadge path="/config/resolve/extensions" text="resolve.extensions" />
 
 Automatically resolve file extensions when importing modules. This means you can import files without explicitly writing their extensions.
+
+## resolve.mainFields <RsbuildDocBadge path="/config/resolve/main-fields" text="resolve.mainFields" />
+
+Controls the priority of fields in a package.json used to locate a package's entry file. It is the ordered list of package.json fields Rspack will try when resolving an npm package's entry point.
