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.

How to use the ntf server ?
It's about ntf-server-ubuntu-20_04-x86-64 https://github.com/simplex-chat/simplexmq/releases/tag/v5.1.3

SimpleX Chat: private and secure messenger without any user IDs (not even random)
Also, it is covered in whitepaper here: https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md
-
SimpleX Chat – the private messenger without any user IDs (not even random numbers) – v5.1 released with message reactions 🚀 and self-destruct passcode
Please review the whitepaper and / or website home page. I also wrote this post some time ago about why I believe that using pairwise identifiers should be a minimal requirement for a communication system to be considered private.

Large file : 8Mb file limit
For more information see Simplex development roadmap xftp branch in github
-
SimpleX File Transfer Protocol (aka XFTP) – a new open-source protocol for sending large files efficiently, privately and securely – beta versions of XFTP relays and CLI are released - developed in Haskell!
The source code: https://github.com/simplex-chat/simplexmq/tree/xftp

SimpleX File Transfer Protocol (aka XFTP) – a new open-source protocol for sending large files efficiently, privately and securely – beta versions of XFTP relays and CLI are released!
You can download XFTP CLI (Linux) to send and receive files via the command line here - you need the file named xftp-ubuntu-20_04-x86-64, rename it to xftp.

SimpleX Chat – the 1st messenger without user profile IDs (not even random numbers) – v4.4 released with disappearing messages and connection verification!
We absolutely should assume they can be compromised, but as SimpleX servers do not participate in the initial key exchange for e2e encryption, the server compromise will not lead to the compromise of e2e encryption security. I wrote more on MITM issue in this post. Further, the threat model here explains other consequences of compromised SimpleX servers.

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?

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!
