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…

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…
