    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…

    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…

    Hey HN, I'm Marcel from Tusk. We’re launching Tusk Drift, an open source tool that generates a full API test suite by recording and replaying live traffic. How it works: 1. Records traces from live traffic (what gets captured) 2. Replays traces as API tests with mocked responses (how replay works) 3. Detects deviations between actual vs. expected output (what you get) Unlike traditional mocking libraries, which require you to manually emulate how dependencies behave, Tusk Drift automatically records what these dependencies respond with based on actual user behavior and maintains recordings…

    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
