Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What am I missing about interfaces?
a. you might do so purely out of argo cult, i.e. because someone told you this was the right thing to doâ„¢, and that's a silly exercise. b. you could also be doing this for a good reason: to use the interface with a mocking tool like NSubstitute

The Moq-gate: You Either Die a Hero...
When comparing it to one of its most well-known alternatives, NSubstitute, which has "only" reached 85.6 million downloads, it is fair to say that Moq is the most widely used mocking library in the .NET ecosystem.

Since v4.20, Moq is harvesting email addresses
Maintainer rejected the PR. They have temporarily disabled the integration in https://github.com/moq/moq/pull/1375 but kept the SponsorLink project reference in the source code. It seems like their intent is to re-enable the integration at a later point :(
NSubstitute [0] might be an alternative. Or to fork Moq pre-4.20.

Setting up a simple testing project with C#
In terms of mocking there are several frameworks you can use, but I've mainly relied on Moq and NSubstitute. Within this demo, I'm going to use NSubstitute as I've found it a little easier to use.

Easier TypeScript API Testing with Vitest + MSW
However, I discovered a great combination that transformed my API call testing in TypeScript: Vitest and Mock Service Worker (MSW). Their well-crafted design makes them incredibly easy to use, enhancing the overall testing experience.

Creating mocks for testing react code
While mocks are effective, they require modifying the component's internal logic or mocking global functions like fetch. This can become cumbersome for complex components with numerous API interactions. Here's where MSW shines.

Storybook 8
> For those wondering what the use case is, you must not have tried it. It does take work to set up (with each version that's less), but it can be very nice to test in isolation esp in cases where a component is under a login, the 4th page of a 10 page form, etc. Also obviously if you're working on a component library that ships without an app, Storybook can be your development and/or demo app.
I have worked with storybook extensively over the past couple of years and my team is moving away from it in favour of MSW (https://mswjs.io).
For "4th page of a 10 page form" during the development there's hot reloading which is really stable nowadays and haven't failed me, although I understand that some setups are old and it might be easier to configure Storybook than good hot reloading.
I'm not entirely sure about the testing part of it and I'd be grateful if you could elaborate. I haven't felt the need for some special setup with SB because for unit tests, I can test a deeply nested component separately. For E2E tests, I usually test the whole form.
I agree on the component library part, this is probably the only use case where Storybook is 100% justified, but I'm unconvinced about the
