shoutem/webpack-prepend-append

This is a Webpack loader that prepends and appends text to files during the bundling process, allowing developers to add headers, footers, or wrap content consistently across their codebase. It's designed for Webpack users who need to modify file contents automatically, such as adding licensing headers or wrapping modules in specific code blocks. The tool is particularly useful for frontend developers and build engineers working with JavaScript projects that require consistent file modifications during the build process.
