Products that do what Belgie – Run TypeScript from Python in an Embedded Deno Sandbox does
Hi HN! I built Belgie, a Python library that embeds Deno, allowing Python applications to run JavaScript and TypeScript without requiring Node.js or Deno to be installed on the host system. It supports the features you’d expect from Deno (npm, JSR, and URL imports, isolated package environments, etc.), plus: - Pass JSON-safe values seamlessly between Python and JavaScript. - Agentic code generation with typed interfaces, similar to Pydantic’s Monty. - Manage dependencies programmatically or from the CLI.

This demo is build with subZero [0] - The TypeScript library to build internal tools fast Everything is running in JS (express+react-admin), there are no external dependencies (other supporting services), which makes for an easy deployment (single container/service) to any platform that can run JavaScript. The demo uses SQLite as the db but PostgreSQL/MySQL/ClickHouse are also supported. [0] https://getsubzero.today/

Shelon: https://github.com/housni/sheldon It's not a framework, it's a library. It attempts to mimic function names in Python. Most functions work in Bash 4.3+ but there are those that work on older versions. The 'help' target in Makefile is on crack! Check the issues in that repo for upcoming features. Useful for DevOps Engineers or anyone who has to write Bash scripts.

Hi HN, I’m Guillaume, the cofounder of Bearer, an Open Source SAST solution. After launching a few weeks ago here on Hacker News with support for Ruby and JavaScript stacks, I’m happy to report we’ve just released a new version (v1.2) with TypeScript support! In terms of code coverage, we use the same rules already implemented for vanilla JavaScript, but as usual, you can build your own. The rules list is here: https://docs.bearer.com/reference/rules/ It’s a first version for TS, but we believe that thanks to the pre-existing JavaScript support it should already…

I've built a type-safe semantic layer in code, for ClickHouse. If you're building analytics off ClickHouse in TypeScript, I would love your feedback. With hypequery there is no platform to adopt, no YAML sprawl. It runs where your app runs. Key features: - Define metrics once, reuse them everywhere: Declare dimensions and measures in one place and then pull from the same source of truth. - Compiles to ClickHouse SQL: No service, no proxy, no extra runtime to deploy. It's a library that generates SQL and runs where your app runs. - Multi-tenancy & Authentication ready: Cross-tenant queries…

Tired of bloated installers and complex DevOps pipelines? I built PPORT — a terminal-based messenger — to demo a crazy simple idea: 1. Instant CLI delivery over HTTP 2. Just curl or irm, nothing else 3. TypeScript on the fly via Deno 4. Live deployment without Docker or builds How it works: Visit https://pport.top Run one command (curl -fsSL pport.top | sh) PPORT streams scripts and source files dynamically based on your client (curl, browser, Deno) No packaging. No compiling. No friction. Source on GitHub: https://github.com/vseplet/pport Curious what else…

Hey everyone, we just released a new version of our Infrastructure as Code Python SDK that now runs entirely on your machine - no account required. LaunchFlow extends OpenTofu to provide features like multi-environment support [1], autoconfigured infrastructure clients [2], and API release management [3]. Our goal is to provide a Python-native infrastructure toolkit that handles everything from automating your infrastructure to using it in your application code. You can use our library of preconfigured OpenTofu modules to add GCP / AWS infrastructure to your app with just a few lines of…

Hi folks, I started thinking some time ago about how to use ReactJS's server-side features with backends that aren’t specifically built with Node.js or Deno. After some research, I found that the only strict requirement is a JS engine for server-side rendering, while the rest of the runtime can be in any language. For this reason, I started developing a full-stack ReactJS web framework with a Rust-based backend (the API draws heavy inspiration from Next.js). The server performance is already impressive, with a 4x improvement over the latest Next.js. We’re tracking it in a separate…

I wrote a forward auth server in TypeScript and Deno. I've written several forward auth servers before but they have always been specifically written for that application. I wanted something more generalised that I could re-use. What is forward auth? Web servers likes Nginx and Caddy and Traefik have a configuration option in which inbound requests are sent to another server before they are allowed. A 200 response from that server means the request is authorised, anything else results in the web server rejecting the request. This is a good thing because it means you can put all your auth…

The latest CLI releases from google and anthropic are sweet, we wanted build one that can run any model. mcp-use-cli lets you `/model` hop between providers instantly. npm i -g @mcp-use/cli && you're done What's cool: - BYOK (your keys, encrypted locally) - Slash commands for everything - MCP protocol support for custom tools - Works with OpenAI, Anthropic, Google, Mistral, Groq, local Ollama... The whole thing's TypeScript and open source. Built this on top of our Python + TS mcp-use libs, so it speaks MCP out of the box. You can hook up filesystem tools, DB servers, whatever you…

Hi HN! This is Qian here with Peter (KraftyOne) and Jeremy (jedberg). We’re building DBOS, an open-source, lightweight durable workflows library that you can add to Python apps in just a few lines of code. It’s comparable to popular open-source workflow and queue libraries like Airflow and Celery, but more lightweight with a greater focus on reliability and automatically recovering from failures. Our goal in building DBOS is to make workflows lightweight and flexible so you can add them to your existing apps with minimal work. Everything you need to run durable workflows and queues is…

Hi! I wanted to understand more about databases' internals so I wrote one from scratch. It has a T-SQL inspired syntax with support for functions and procedures. It can be used stand-alone as a SQL engine or with a server allowing for persistence and replication to other connected clients. Performance are nothing near sqlite of course but that's beside the point. It’s a small database engine that can run in a web app as a way to store session data, do small calculations on a web worker, store the document/data the user is editing or facilitate “multiplayer” feature by broadcasting the…

Hi, I'm an ipywidgets maintainer, which is a library for writing interactive widgets in the Jupyter notebook. For our living, we help organisations create larger applications, and sometimes turn them into user facing web applications using Voilà. Over time, we noticed that making larger application hit the same problems as web applications in the jQuery era (state transitions being the biggest issue). To tackle this issue, instead of coming up with our own declarative UI solution, we implemented the React API in Python. I think it is fair to say that ReactJS has proven itself, taking away…

MicroPython (lexer, compiler and VM) on the SNES: 3.58 MHz 65816, 56 KB Python heap, 16-bit int. The REPL runs right inside the post via EmulatorJS and also works on real hardware via flashcart. I did this as a benchmark for Claude Fable. When the export ban hit, switching to Opus got the project stuck for three weeks; Fable came back and found the real bug in ninety minutes. Along the way: 23 compiler bugs and 4 MicroPython bugs, each root-caused with a minimal reproducer and filed upstream. If you run it on real hardware, I want a picture!
