Leveraging the import statement within lib.d.ts to enhance Intellisense functionality in Visual Studio Code

Looking to streamline my JavaScript project by utilizing custom global variables and harnessing the power of VSCode intellisense for auto completion. Here's what I'm aiming for:

See example of auto completion for 'lol'

After some searching, I discovered a technique involving using a lib.d.ts file in the same directory as my script. As long as lib.d.ts is standalone like this:

// Contents of "lib.d.ts" file
class Lol {
    f() : string;
}

declare const lol : Lol;

everything runs smoothly. However, when attempting to separate the Lol class into its own file, intellisense fails to display the lol variable in my script:

// Contents of "lol.d.ts" file
export default class Lol {
    f() : string;
}
// Contents of "lib.d.ts" file
import Lol from "./lol";

declare const lol : Lol;

Is there a solution to this problem?

Answer №1

I have stumbled upon the solution. Even though scripts (using declare style) may clutter up the global scope and are unable to utilize import, modules have the capability to achieve both tasks. Instead of relying on declare, I made the switch to export global as shown below:

import Funny from "./funny";

declare global {
    const joke : Funny;
}
