Express/Connect Babel Transpilation Middleware

This package provides an Express/Connect middleware for dynamically transpiling JavaScript files from ES2015+ to ES5 using Babel. It supports caching the transpilation results in memory or to the file system. Currently at version 0.3.4, the package appears to be abandoned, with its last known update significantly predating modern Babel (v7+) and the widespread adoption of ES Modules in Node.js. It relies on older Babel configurations, such as the now-deprecated `es2015` preset, and exclusively uses CommonJS module patterns. Its primary utility was for development environments, enabling on-the-fly transpilation without a separate build step, but it is not suitable for contemporary projects due to its age and lack of maintenance.
