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.

6 Reasons why JSON Schema is worth your time
In the JavaScript ecosystem you can use the excellent AJV package to validate any JavaScript object against a JSON schema. This is especially useful to ensure that API contracts are maintained when communicating with other services.

Migrate Your Express Application to Fastify
Since Fastify supports schema validation with Ajv, the validate module is no longer required on the /shorten route, and we can specify the JSON schema directly on the route. The controllers for both routes will largely remain the same, except that the res parameter is renamed to reply as before:

Has anybody used Typia library?
There's a ton of schema validators out there and most devs have their personal favorite. Mine was zod and is now typebox + ajv.

Accept only specific keys in JSON or form-data format in express?
Good validator library: https://www.npmjs.com/package/ajv

Advanced Fastify: Hooks, Middleware, and Decorators
Fastify uses JSON schema to define the validation rules for each route's input payload, which includes the request body, query string, parameters, and headers. The JSON schema is a standard format for defining the structure and constraints of JSON data, and Fastify uses Ajv, one of the fastest and most efficient JSON schema validators available.

Getting Started with Fastify for Node.js
In Fastify, JSON schema validation is a built-in feature that allows you to validate the payload of incoming requests before the handler function is executed. This ensures that incoming data is in the expected format and meets the required criteria for your business logic. Fastify's JSON schema validation is powered by the Ajv library, a fast and efficient JSON schema validator.

How can we map data from JSON to typescript object efficiently?
I think you're looking for a json schema validator like Ajv or Zod.

5 useful JSON tools to improve your productivity
We can use JSON Schema to validate that our data adheres to a specific structure. Ajv is one popular validator tool for JavaScript applications that allows us to create a schema and then validate JSON against that schema. Here's an example of using Ajv to validate one of the above JSON examples against a schema:

Ask HN: JSON API object type definitions and validation in 2023?
Hey HN,
We're designing a new system and have been kicking the can about JSON object definitions and validation. Soon we need to settle on a system to validate API request bodies and provide helpful error messages.
In the past, I've used JSON Schema ( https://json-schema.org/ ) to define definitions and ajv ( https://ajv.js.org/ ) to validate, but it's a bit verbose and ajv validation errors are more cryptic than I'd like to deal with.
TypeSchema looks interesting. It seems solid (and perhaps stable?), but development hasn't been active for 2 years. It also looks like we'd still need to generate JSON Schema and choose a validation library
Anyway, I'm very curious how others are approaching this problem. How do you organize and generate validations for your type definitions? What libraries do you use to validate and provide human readable error messages?
Thank you!

What are your favorite End-to-End encrypted tools for online privacy?
For messaging I'm currently on Olvid (E2E with physical key exchange) but since it still use their servers, I'm currently testing SimpleX where I can host my own servers.

U.K. Abandons, for Now, Legislation That Would Have Banned End-to-End Encryption
If you have a mobile phone number, the domestic intelligence agency knows exactly where you are at all times and any LEO (without a warrant) can also find you. In addition, there have been numerous CCC presentations showing how insecure the global (excluding US) and (separately) US carriers are guilty of promiscuous metadata trafficking ($$) and insecure SS7 setups. As a consequence, for low $, you can go to any one of several shady websites and find the last location of almost any phone number (person unique ID) globally. There are additional varying exploitable vulnerabilities depending on the exact combination of {handset x carrier x country} to impersonate them, tap their line, reveal their exact location, and redirect their phone number through a third-party handset or even a PBX. These are more expensive and some capabilities are forbidden for all but a few selective intelligence uses.
Session (Signal fork) doesn't use phone numbers. It's pretty well-designed overall and uses an onion routing approach. It's already a superset of Signal except it doesn't use phone numbers. https://getsession.org

PS: Using regular TOR on home broadband or cloud servers is relatively risky and inefficient. Sybil attacks on it are common. And to network operators and security agencies it gives an easy "flow tag" of your uplink and exit node data traffic as automatically suspicious.
