    PeerJS

    PeerJS

    Simple peer-to-peer with WebRTC

    ...Note that no peer-to-peer data goes through the server. The server acts only as a connection broker. If you don't want to run your own PeerServer, we offer a free cloud-hosted version of PeerServer. PeerServer is open source and is written in node.js. You can easily run your own. PeerJS simplifies peer-to-peer data, video, and audio calls. Add the PeerJS client library to your webpage. The Peer object is where we create and receive connections. PeerJS uses PeerServer for session metadata and candidate signaling. Every Peer object is assigned a random, unique ID when it's created.

    jwt-cli

    jwt-cli

    A super fast CLI tool to decode and encode JWTs built in Rust

    A super-fast CLI tool to decode and encode JWTs built in Rust. jwt-cli is a command line tool to help you work with JSON Web Tokens (JWTs). Like most JWT command line tools out there, you can decode almost any JWT header and claims body. Unlike any that I've found, however, jwt-cli allows you to encode a new JWT with nearly any piece of data you can think of. Custom header values (some), custom claim bodies (as long as it's JSON, it's game), and using any secret you need.
