What is env-update-check

Env update check package provides checking system for environment variables, that ensures that you never forget to change environment variable again when you're deploying your application.

How does it work?

Create .env.check file with variable names you want to check and their status as it's displayed below:

TEST_VARIABLE_1=unchanged
TEST_VARIABLE_2=unchanged

Setup env-update-check to run in your CI script.

Then each time you change variable value or add a new variable, change it's value to changed like below:

TEST_VARIABLE_1=changed
TEST_VARIABLE_2=unchanged
NEW_TEST_VARIABLE_3=changed

After your new code changes get to your staging or main branch, your build will fail until you both change the variable in your environment and then in .env.check file.

unchanged == no change
changed == changed - will error out on staging and prod
staging-changed == changed on staging - will error out on prod only 

Now commit your changes and enjoy (hopefully) smooth deployments. ⛵️

Currently production check is avaliable only when your production branch is named main. Tested only on Gitlab CI
