It will just goto either the client or the server. It would be optimal if all relevant definitions were returned. ### 💻 Use Cases Example project: ```ts // shared/shared.ts let x: Thing; // < goto definition here // project1/tsconfig.json ... // project1/thingA.ts interface Thing { a: string } // project2/tsconfig.json ... // project2/thingB.ts interface Thing { b: number } ``` Currently this is returned (depending on order of project load): ```ts interface Thing { a: string } ``` What ideally should be returned: ```ts interface Thing { a: string } interface Thing { b: number } ```
