Common Middleware

common-middleware is a JavaScript utility library that provides a collection of reusable middleware functions designed for applications built upon the `base-methods` framework, particularly for projects like Assemble, Verb, Generate, and Update. It currently stands at version 1.0.0, last updated over two years ago, indicating a maintenance phase rather than active development. The library focuses on processing file objects in a pipeline, offering functionalities such as front-matter parsing, escaping and unescaping template delimiters, and managing JSON data on load and pre-write. Its key differentiator is its integration within the `base` and `assemble` ecosystem, providing standardized pre-processing capabilities for file-based templating and content management workflows common in static site generators or documentation builders. It is specifically designed for Node.js environments, historically supporting versions `0.10.0` and above, and primarily uses CommonJS modules.
