Products that do what How to test whether a STUN/TURN server is working properly does
A few days ago, I created a simple service for my WebRTC Project: https://github.com/miroslavpejic85/mirotalk to test if the STUN/TURN servers are working properly. After installing and configuring a STUN/TURN server, most of the developers that are new to this stuff will ask themselves, how do I know if it's working properly? So I made a snippet :) ``` Test Stun/Turn Servers Test Ice Servers The STUN server is NOT reachable! The TURN server is NOT reachable! const Ice = document.getElementById('ice'); const IP = document.getElementById('ip'); const Stun =…

I built this because I wanted to make outbound and accept inbound HTTP/3 and raw QUIC connections from ordinary Node.js code, without building Node from source or putting everything behind a reverse proxy. Repo: https://github.com/currentspace/http3 npm: https://www.npmjs.com/package/@currentspace/http3 It’s a native package around Rust/quiche. It supports both client and server APIs, I'm using it in a couple of projects: creating raw QUIC streams, datagrams, custom ALPN, session behavior, and HTTP/3 client work from Node. I've…

Requirement: - Excellent feedback during development - Debugging with source maps Method: I'm using these scripts in package.json. "scripts": { "di": "node-inspector -d=7000 -p=8000 --save-live-edit --hidden node_modules/", "ds1": "babel ./server -d ./build/server -s -w", "ds2": "nodemon --watch ./build/server --delay 100ms --debug=7000 ./build/server/main.js" }, Then run "npm run ds1; npm run ds2; npm run di" Why: I took some time to put this together, after navigating all the tools out there. I personally find this to be "correct". Thought I'd…

Hi HN,<p>In my spare time (evenings and weekends) I've built 3 products which have been relatively successful even with little advertising (only google ads budgeted at $30 per day). The latest one is WcfStorm.Rest; which is a REST service test client. I built it because I found that the current tools did not have the features I wanted such as, intellisense when working with HTTP headers, syntax highlighting for JSON messages, etc.<p>I'm continually trying to improve these products and would very much love get your feedback. Every suggestion is welcome!<p>(My apologies…

For the past months we've been working on making our open source tool Internet.nl easier to deploy and develop on. Last week we release version 1.8.0 (https://en.internet.nl/article/release-1.8/) which includes these changes. Tests include: IPv6, DNSSEC, HTTPS/TLS, various security options like XSS, CSP headers, security.txt, RPKI, DMARC, DKIM, SPF, STARTTLS, DANE for web/email, and a browser connection test for IPv6 and DNSSEC. (see: https://en.internet.nl/faqs/) Using Docker & Docker Compose it is now trivial to deploy your own…

It's been a year since my original Show HN post [1] announcing Server Check.in [2], so I thought I'd post a reflection after my first year running the service. Server Check.in is an inexpensive website uptime monitoring service that I started out of my own need—if I had no users, I'd still keep it going. Fortunately, there are enough paid customers to keep me interested, and I've learned a lot from their feedback. I had a good initial batch of signups after the announcement post on HN. These early customers gave me a lot of feedback, and some suggested fairly major revisions to the service.…

I made an API mocking tool that imports a schema, populates fake data, then runs a local server. This is helpful for testing APIs or advanced prototyping. A demo video is here: https://www.loom.com/share/abad2cdf325e4e0b9addea1e14406166?... There’s two fun things about this tool 1. the complete lack of configs and schema annotations. i.e. you don’t need to learn faker-js. You just need your existing GraphQL schema and to to swap out the server URL in your frontend code. 2. the depth. Your fake objects have relationships to other fake objects. And in proxy mode, real…

Optimal UX runs experiments directly on the server side through a Cloudflare Worker, meaning variations are applied before the page even reaches the browser. The core idea is to intercept and modify the HTML stream at the edge, which eliminates client-side overhead. For websites using Cloudflare, it's just a matter of installing the Smart Agent. The same agent works seamlessly with React, Vue, and other frontend frameworks when client-side testing is needed. One unexpected benefit that emerged during development was the ability to quickly apply HTML patches. This turned out to be super…

Hey HN, My brother and I recently wrote a new guide on creating a continuous integration, delivery, and testing pipeline for a Node.js app. Full post: https://assertible.com/blog/set-up-continuous-testing-with-n... Example repo: https://github.com/assertible/nodejs-example The tutorial goes over the different components of a complete CI pipeline: - Push code to GitHub, build and run unit tests on CircleCI - Deploy new app version to Heroku - Post-deployment tests with Assertible The whole workflow is surprisingly easy to set up. We now run automated…

live-paint (https://paint.liveviews.cc/) is a demonstration of ts-liveview v2-rc3. The server converts JSX expression into plain HTML response. The UI is then updated via websocket. As opposite to React.js. The DOM updates are fired from server, and instructed with query selector (no virtual DOM). Hence, the amount of javascript downloaded and executed by client are minimal (or even optional for static web pages).

I’ve been experimenting with building a Node.js HTTP framework using Rust + Hyper with N-Api. The project started as a fully synchronous server, but I recently patched it to support async (Tokio/Hyper). That change alone nearly doubled throughput in benchmarks. What’s different: * Built directly on Hyper, no heavy abstraction * napi glue for Node.js bindings * Minimal core (sync and async engines side-by-side) * Focused on raw performance, not plugins (yet) This is still experimental and not production-ready. I’d like feedback on: * Async API design — does it feel ergonomic? *…

Hi again HN, we’re Arjun and Anirudh, founders of Signadot (YC W20). Signadot helps teams developing microservices test their changes using lightweight environments called “Sandboxes”. We use a relatively new approach, using traffic labeling (using OpenTelemetry) and request routing (using a Service Mesh) to isolate environments in a shared Kubernetes cluster. Today, we’re launching a new feature to help developers with local testing of microservices during the iterative development process. When we initially launched in September last year…

Hey folks, I am finally posting a Show HN post for a project I have been working on for several months now, and it's in a state where I already get a lot of value myself, so I am happy to share broadly. The pitch line is: "Skybear.NET is a managed platform automating Synthetic HTTP API testing." At the moment, the main source file format supported for your API tests are Hurl.dev files [1]. Hurl is a CLI tool wrapping `curl` and it's really awesome. At least check that out :) I am not affiliated directly with the Hurl CLI tool, and the platform I am building provides full Hurl compatibility.…

Logging and tools like Sentry are a thing of the past. A while back on a night out in northern Norway, I had to start debugging a critical production bug that broke the payment flow of my SaaS product. I had limited time to fix the bug or I would have lost about ~1K profit. Super stressful. I had logging and Sentry in place, but neither helped me reproduce or find the root cause of the bug. Ever since, I started thinking; why can’t we just have a tool that you setup once, and that allows us to reproduce every function call and function that the user ran before the bug? This is how the idea…

Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

Hello HN, around October last year, I started to work on campaignkit.cc as a side project. It is a service to detect invalid and malicious email addresses. You can upload text files, and use the REST API or direct integration to retrieve a detailed report for each email address. End of March I added Stripe Payments and got my first paying customers via SEM. A coworker suggested starting a Show HN thread, so here we are :) I used golang for the backend since I wanted something lightweight with fast compilation times (coming from scala). For the frontend, I'm using Next.js and TailwindUI. On…

Hey HN - Today we launched a new globally available Serverless platform that thinks about simplicity and DX first and foremost. Let us know what you think - try it now for free. Traditional serverless functions are islands. Each function handles a request, does its work, and forgets everything. Need one function to talk to another? You’ll be making HTTP calls over the public internet, managing authentication between your own services, and dealing with unnecessary network latency for simple internal operations. This architectural limitation has held back serverless adoption for complex…
