As you probably saw my founding of two nice libraries that allow you beauty and easy abstraction on dot and just environment variables. You can check it there
After some time I decided to create another open-source library for the world and I merged the functionality of packages which you can find in the article above. I started from scratch and you are more than welcome to have look on it on my GitHub -> github.com/lalabuy948/genvutils
I decided to share this because I was looking for small, simple and easy to use tool where I would store dotenv secrets for my apps. And I found this nice and elegant solution which will allow you to control your application secrets with small bash script. 🙂
You can find nicely described steps here: Getting started
I was doing hobby project, nothing special, server with authentication few endpoints and connection to database. I wrapped this project in docker to distribute project to another developer, he wanted to help with fronted but not that fluent at the backend part. Then I realized that my friend does not want to struggle with database setup and so on. So, solution was straight forward - docker-compose.
I prefer using .env instead of typing stuff to cli. I found out really elegant solution. You can still use .env and parse it easily with
github.com/caarlos0/env/v6, specify default values or even load file (certificates etc). But in docker-compose you need to specify same ports for database for example. Here comes github.com/joho/godotenv, if you provide environment variables via dockerfile or docker-compose it will override constants in your .env.
