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.

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
Additionally, thank you to all our community launch partners across the frontend ecosystem for helping us bring Storybook 8 to the world!

How to Automatically Consume RESTful APIs in Your Frontend
With orval, we can also integrate the API client in our unit tests. Orval provides first class support for mocking through the (Mock Service Worker)[https://mswjs.io/] library, and it can automatically generate the MSW handlers for testing server.

How to Successfully Integrate with Legacy APIs Using NodeJS
Consider a hypothetical scenario where data from a list of companies within an ERP needs to be retrieved. As a personal recommendation, leverage tools like MSW for top-level mocks, which can significantly enhance the testing process.

Testing Defer Blocks in Angular with Cypress
Recently I came across this issue while triaging some issues at Cypress. (Shout out to MattiaMalandrone for creating an issue with clear instructions for how to reproduce). After quickly replicating the issue I sought after a solution which ultimately inspired me to write this article.

/Does Cypress Component Testing Work With Libraries
This questions was asked a while ago and pretty much went unanswered: https://github.com/cypress-io/cypress/issues/23677. If it doesn't work with libraries yet I will stop battling with it for now. If it doesn't work, what are you using to test libraries?
