You can get the same type (readonly ['small', 'medium', 'large']) like this:

When you have routes defined with only route params this is the behavior you get. This is why it is bad practice to not have a constant path and have only route params.

Quick hack fix is to move any routes that start with params to the end of the routes array.

The real fix is to add a constant to the beginning of those routes. Such as “category/something/something-else” for the category component.

You are not using the forkJoin operator correctly.

An observable that is complete will no longer emits data. Take it like a closed pipe. ForkJoin will wait that all steams are completed (closed) before emitting one single data.

If you're fetching your data using this.afs.collection(...).doc(...).valueChanges(), these observables stay active. They will emit each time the data is updated in firestore.

To complete them, use a take(1) or first() (they will emit once then complete), or use combineLatest() to combine active streams and keep your data updated in real time (don't forget to unsubscribe onDestroy to prevent any memory leak).

Here's an example with completed streams:

See my answer in Import a JavaScript module or library into TypeScript if you're having problems importing modules generally using TypeScript and JavaScript in the browser.

I share many of the same frustrations! It's so hard to get Typescript working nicely with Javascript and the microsoft documentation is so obtuse!

In your case : the path to a library is always looked for in node_modules so in that case you don't need to add the full path.

You also never need to import a .d.ts file. You can just put the .d.ts file somewhere in your working folder and VS Code will detect it.

If you have the .d.ts file for moment.js, you will get type completion in VS Code. You don't need to import moment.js when you load it with a

If I understand you correctly what you need is

In your test, you setup a mock version of value, dispatch which does not trigger update when you click on Block mine button.

But in actual code, in App.tsx you use useReducer hook (deep down it trigger re-render and new props is passed to Statistics via Context).

To fix it, just simulate your test with useReducer

I checked TypeScript's own code, and there's no evident way to change how the declare module line is generated. Fortunately, you can just prevent it from being generated at all. You're getting an ambient external module declaration (declare module) because you're using --outFile instead of --outDir. Here's how to generate the same types/aabb-3d/index.ts file as an ES-style module declaration without declare module:

I would recommend looking directly at the TypeScript handbook page linked from the post you linked, as the post itself is rather old and the copy of the text there is a bit outdated. In particular, "types" is now preferred over "typings" in package.json, although both should still work.

However, you and the post are correct that the issue is one of ambient external modules ("ambient modules") vs. non-ambient ones ("external modules"). You should just need to remove the declare module block wrapping around your file, leaving its contents at the top level. That will transform your declarations from ambient to non-ambient and should make it work.
