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.

[DDD] Tactical Design Patterns Part 3: Presentation/Infrastructure Layer
This is the request body when creating a new task. The IsString decorator provided by class-validator rejects all types other than strings, including undefined or null. The task name value object does not consider the possibility of values other than strings.

How can I declare, integrate a JSON (or similar type that is supposed to be data sent from a server) file into my Angular app, and use it;s data to display the array of Devices within it?
Also OP can check out class-transformer + class-validator if he want to properly instantiate objects and validate them with precise and verbose output of potential format errors. OP can even go the god tier way by setting up a custom RxJS operator that does that for him easily.

NestJS vs. Ditsmod: auto-validation
The description of the request body model in NestJS is similar to the description of Ditsmod models, but NestJS uses decorators provided by the utility class-validator. In NestJS, it is customary to name the request body model with the ending *Dto (this is an abbreviation of Data transfer object):

Is there any reason not to use typescript?
You could use Zod or Superstruct to validate the types of values, or use typestack/class-validator if it makes sense.

I found 10,000x faster TypeScript validator library
Also, title of before article was I made 1,000x faster TypeScript validator library, but today's benchmark is showing that typescript-json is maximum 6,500x times faster. It's just because I added a new library class-validator in the benchmark and it is much slower than previous zod. Of course, I've continuously tuned the performance, but it just improved the performance about 2x times only.

React Server Components Example with Next.js
Another interesting point is that executing fetches on the server can allow developers to more easily leverage caching. Next.js already handles caching out-of-the-box and Iām curious to see if the wider adoption of RSC reduces the need to combine React with solutions like Apollo Server and Apollo Client. While there are other benefits to these tools, RSC could provide similar caching behavior without the need to invest in a GraphQL solution.

Who moved my error codes? Adding error types to your GoLang GraphQL Server
While working on this blog post, I learned that Apollo Server, the most popular GraphQL server for typescript, uses a similar method for adding error codes to GraphQL. It even lets you add custom errors. Hopefully, someday other GraphQL server projects will follow them. Until then, weāve got a strong indication we took the right approach.

How we migrated to Apollo Server 4
After some head-scratching, I opened an issue on Apollo Serverās GitHub repository. There, Apollo Server contributor @āglasser shared a helpful suggestion: why not invoke our AuthPlugin from Apollo Serverās context function? Throwing from context would ensure we can control the HTTP status response without having to introduce more methods and error checks to our AuthPlugin (like unexpectedErrorProcessingRequest). With that suggestion in mind, we rewrote our AuthPlugin as follows:
