Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

I like the idea of using dotenv files, but I dislike having to use different language-specific libraries to read them. To solve this, I created a small utility that lets you prefix any command with "dotenv" to load the ".env" file. This is how I imagine dotenv would work if it had started as a UNIX utility rather than a Node.js library.

Since last time i posted about dotenv-diff a few things has improved - “did you mean” type suggestions - comment warnings flag (every key in your .env.example must have a #comment above or next to the key) -now whenever you run dotenv-diff it will warn you about difference in you example file if its run against your .env file -catch secret keys that you definitely dont want in your example file -smaller bug fixes

Hey HN! I've built this cli tool to manage env variables of a project, but mostly for fun and to try out Rust and the clap crate. I had this idea when I made a big mistake and broke some production stuff because I had a very messy .env file laying around in my project. I was implementing new features for one of my projects and in my .env file I had the test database url commented out and the production one was not. Long story short, I applied migrations to the production database instead of my local test one and broke a lot of production APIs :') I wanted a tool that could easily help me…

I built a cli tool that gets you started with TypeScript development with zero config. Initially created to solve my own problem but thought it might be useful for others as well. - SWC compiler - TypeScript type check support - Live reload support - .env file support - Path alias support - Typescript script runner - REPL support Please tell me I am not going down a rabbit hole.

Hello, folks. I'm Jiang, the author of ESInfer. I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system. To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript. It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes. It is still in the very early stage, which offers…

It works on my machine" is still the most common deployment bug I kept running into the same stupid deployment issue. Everything works locally. Tests pass. I deploy. Production crashes. After digging through logs for an hour the problem ends up being something simple like: • a missing environment variable • something added to .env.example but not to .env • a config mismatch between environments The most common one for me was forgetting to add a variable locally after adding it to .env.example. So I built a small tool to catch this instantly. It compares .env and .env.example and tells you if…

When building a plugin system for an application, avoiding dependency conflicts is critical. To address this, I created Wetlands – a lightweight Conda environment manager. Wetlands not only simplifies the creation of isolated Conda environments with specific dependencies, but also allows you to run arbitrary Python code within those environments and retrieve the results. It uses the multiprocessing.connection and pickle modules for inter-process communication. Additionally, one can easily use shared memory between the environments, making data exchange more efficient. Docs:…
