📦 @rollup/plugin-replace

@rollup/plugin-replace is a Rollup plugin that replaces targeted strings or regular expression matches with specified values during the bundling process. This is particularly useful for substituting environment variables or feature flags in your code at build time. By replacing placeholders with concrete values, the plugin enables conditional code execution and customization without impacting runtime performance. It streamlines production builds by eliminating unnecessary branches and optimizing for specific environments.
