I'm trying to add a .d.ts file to type the default export of a module, but I just can't get the types to show up in VS Code's intellisense, would love to see an example if anyone has or knows of one

If there's a jsconfig, you'd need to add a "types" field. You can also include a reference comment in the files you are working on.

@warm bear thanks! yeah, just a jsconfig—do you have an example? I can't find any docs on the types field for jsconfig

Although I did find this https://stackoverflow.com/questions/32296299/including-d-ts-type-definition-files-in-vscode

Stack Overflow

Including d.ts type definition files in VSCode

I've started using VSCode 0.7.0 and noticed the notes say you don't have to add /// references anymore:

With the introduction of jsconfig.json, you no longer need to use /// references in each file (

@warm bear or do you mean a jsdoc that imports the .d.ts?

Ah I'm guessing you're talking about https://www.typescriptlang.org/tsconfig#types

TSConfig Reference - Docs on every TSConfig option

From allowJs to useDefineForClassFields the TSConfig reference includes information about all of the active compiler flags setting up a TypeScript project.

but then I would loose types for other libraries unless I listed each of them in the "types" field too, right?

okay, importing in a jsdoc with /** @type {import('./db.d.ts').DB} */ worked, ty!
