Accessing Version Number from package.json in Create-React-App Projects
This article addresses the common challenge of accessing version numbers from package.json files in Create-React-App projects. Due to Create-React-App's default restriction on importing files from outside the src directory, direct imports of package.json result in module not found errors. The article analyzes two primary solutions: using environment variables and creating symbolic links. The environment variable approach injects npm package information into the React application through .env configuration, while the symbolic link method creates a link within the src directory to bypass import restrictions. Both methods have their advantages and limitations, with environment variables aligning better with Create-React-App's design philosophy and symbolic links offering more direct access. The discussion includes practical considerations and use cases to help developers choose the appropriate method for their specific needs.
