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.

Eloquent JavaScript 4th edition (2024)
It is (or should be) common practice to parse/validate any external data you depend on. You should be doing this for Javascript too. I find that the library https://zod.dev/ is quite helpful for this

How to build a blog with Astro
Astro uses Zod, a Typescript-first schema validation library, to type-check the collections' schemas. It helps validate data types when using collections inside UI components.

Translating zod errors with next-intl
When starting a new project with Next.js these days, next-intl and zod are my go to libraries for internationalization and schema validation, respectively. Of course, when using zod for client-facing validations I would like to translate potential error messages. The package zod-i18n can be used to achieve this for i18next, a popular alternative internationalization library. This means that by using this library as starting point one can quickly achieve zod translation with next-intl.

Htmx vs. React: A Complete Comparison – Semaphore
That is certainly one interpretation, but even then within most compile-time but not runtime-checked languages you can usually perform runtime checks. For example I've used Zod (https://zod.dev/) quite a bit in typescript to do runtime typechecks at the boundaries.

I write HTTP services in Go after 13 years (Mat Ryer, 2024)
So far I like the commonly used approach in the Typescript community best:
1. Create your Schema using https://zod.dev or https://github.com/sinclairzx81/typebox
2. Generate your Types from the schema. It's very simple to create partial or composite types, e.g. UpdateModel, InsertModels, Arrays of them, etc.
3. Most modern Frameworks have first class support for validation, like is a great example Fastify (with typebox). Just reuse your schema definition.
That is very easy, obvious and effective.

[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.

TypeScript-based REST API template to quickly bootstrap your next project
Hello, In the last month I built a REST API template in Typescript to quickly bootstrap new projects, I tried to use the most updated modules available, I've also included a "todo" sample just to showcase how all the things work together, the main modules that I've used are: - expressjs + tsoa that allows to easily generate the OpenAPI spec without any additional steps (just declare your controllers via typescript) - class-validator to validate body requests (this is also useful as the OpenAPI will be automatically generated based on the classes that you define) - Jest for testing, I've included also unit and integrations test samples with an in-memory database
