My /typings/$app.d.ts file has the following structure:
declare class App {
test: object
}
export const $app: App;

In order to enable intellisense, I have to auto-import it, resulting in a line like this at the beginning of my javascript code:
import { $app } from "../../typings/$app";
However, this causes some errors since it is a d.ts file.
Is there a way to make this $app.d.ts file global similar to how the window object works?
In a .d.ts file, using the keyword 'declare var something' at the top level scope is the way to expose a global variable. Avoid using 'export' if you do not intend to export anything.Declare a class App {
test: object
}
Declare a global variable $app of type App;
Adding on to @hackape's response, I suggest including a tsconfig.json file in the root of your project if you haven't already done so. It's worth noting that you can also utilize tsconfig even if you're not working with TypeScript, simply for the benefits of intellisense.
A basic tsconfig.json file might look like this:
{
"compilerOptions": {
"allowJs": true,
"typeRoots": ["./typings"],
"outFile": "./justANameToMakeTSHappy.js"
}
}
The allowJs option allows vscode to apply types to JS files as well. typeRoots informs TypeScript where to locate your type definitions. Lastly, outFile prevents the error 'can't overwrite file ****.js'.
Why does the TypeScript type checker allow a prop with a function parameter that does not strictly match the definition? For example, I have a function called callbackImpl = (str: string): number, which is passed as a React prop parameter defined as callb ...
