Developer guidelines

Code

• Everything to build your project should be in the repository.
• Have your infrastructure as code in the repository.
• Have system variables defined in one location.
• Exclude project secrets in the repository or encrypt them.

Testing

• Found a bug? Recreate it with test code before working on the solution.
• Prefer integration tests to mocking.

Documentation

• Have documentation in the same place as the code. Preferably generated by the code.

Servers

• Do not restart a Linux server to "fix" a problem, it probaly won't.
• Use a provision utility. Restrain from editing anything manually.
• Use the lowest possible privileges. Using root is dangerous.

Security

• Use a password manager.
