Best practices for managing and storing secrets in frontend development

Managing secrets and credentials in frontend development is crucial to prevent security breaches and potential damage. Public APIs, like Google Maps, are accessible to all developers and require careful handling of API keys and credentials to avoid unauthorized access. Bad practices include embedding credential secrets directly in code or uploading them to repositories, which can lead to exposure through developer tools or GitHub crawlers. A recommended approach is to store secrets in a .env file and ensure it is excluded from version control systems like Git. Adding restrictions to API keys can further protect them by limiting their use to specific URLs or request limits. Additionally, using secret scanning tools like GitGuardian helps detect accidentally committed secrets and prevent exposure. It's also important not to share GitHub credentials outside of the development team and to revoke access for those who no longer work on the project. Overall, a combination of storage, restriction, and scanning practices is advised to secure sensitive information effectively.
