Is there a way to navigate directly to the code in a TypeScript type definitions index.d.ts file within Visual Studio Code?

When I command-click on the express() function, it takes me to its definition:

const app = express();

In vscode, it leads me to this line in an index.d.ts file:

declare function e(): core.Express;

However, when I try to jump to the definition of e(), it just brings me back to the same file. I want to see the actual JavaScript code that is behind the types wrapper without having to search for it in node_modules. How can I achieve that?

Is there a way to directly access the underlying JavaScript code?

Answer №1

Currently, in VS Code 1.24, it is not feasible for third-party node modules to achieve this functionality on a general basis. VS Code relies on these *.d.ts files to offer effective intellisense without the need to analyze the original implementation files. Additional details can be found here

While using typings files enhances reliability and performance, it also means sacrificing the ability to trace back to the initial JavaScript implementation.
