How to set up synchronization of development environment configurations between different computers?

Modern developers often work with multiple computers, for example, using a powerful desktop PC at home and a lightweight laptop when traveling. Maintaining the same environment across all devices saves a lot of time and reduces the number of errors. Synchronizing configuration files of code editors, terminals, and auxiliary utilities allows you to feel comfortable at any workstation.

The first step toward a unified workspace is centralized storage of settings in a version control system. Popular code editors and development environments support cloud synchronization out of the box via user accounts. However, for fine-tuning terminals such as Zsh or Fish, as well as Git configurations and SSH keys, it is better to use a personal repository with configuration files.

To manage such files, developers often create a special public or private repository and use symbolic links. Configuration files are physically located in the repository folder, and the operating system accesses them via symlinks from standard system directories. This allows you to make changes to the configuration on one computer, make a commit, and instantly receive the updated settings on another device using a simple pull command.

Special attention should be paid to security when synchronizing configurations through remote repositories. Configuration files should never contain real passwords, access tokens, and secret keys. Instead, environment variables or local files with access rights excluded from version control tracking using an ignore file are used for confidential data.
