Socket-call – Call socket.io events like normal JavaScript functions

Hello HN, I built a Typescript library (named socket-call, for lack of a more sexy name) whose goal is to be able to call socket.io events as regular functions. So you declare your server-side like so: ... const listenEvents = (services: UserServices) => ({ // Add your events here, the name of the event is the name of the function login: async (username: string) => { services._socket.data.user = { username }; console.log(`User ${username} logged in`); setInterval(() => { // Calling an event that's handled client-side services.showServerMessage(`You're still logged in…

In plain words

Socket-call is a TypeScript library that lets developers call Socket.io events as regular JavaScript functions instead of using traditional event emitters. It works by allowing developers to define server-side event handlers as functions and call them from the client using standard async function syntax, eliminating the need for separate event listener and emit patterns. The library is designed for developers building real-time applications with Socket.io who want cleaner, more familiar function-call syntax.

This small library on top of socket.io allows to call events like any regular async Typescript function. import { Server } from "socket.io" ; import { type NamespaceProxyTarget , type ServerSentStartEndEvents , useSocketEvents , } from "socket-call-server" ; const io = new Server ( ) ; user ( io ) ; io . listen ( 3000 ) ; type SessionData = { user ?: { username : string ; } ; } ; type UserServerSentEvents = { showServerMessage : ( message : string ) => void ; } ; const listenEvents = ( services : UserServices ) => ( { // Add your events here, the name of the event is the name of the function login : async ( username : string ) => { services . _socket . data . user = { username } ; console .…from github.com

    I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  • Workout.cool – Open-source fitness coaching platform▲827

    I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
