You just do declare module thing. And what that does is it sets the module as something that exists and who knows what's inside of it. Sometimes you need to type things that are globally available in your project. If that's the case, most common is environmental variables. You need to you can type those as a number or string or an array of values. The only time I ever had one issue with that is one of my packages had like request that cookies was typed as any. But there are certainly times where you know, hunting for the types and writing it yourself just straight up isn't an option.
In this episode of Syntax, Wes and Scott talk about their respective processes for converting JavaScript to TypeScript in their projects, why you might want to, and tooling for moving to TypeScript.
