OData V4 Server for Node.js

odata4-server is an abandoned Node.js library for creating OData V4 compliant servers, originally forked from the equally unmaintained `jaystack/odata-v4-server`. It provides a decorator-driven approach to define OData controllers and expose service metadata (`$metadata`), supporting a wide range of OData query language features like filtering (`$filter`), sorting (`$orderby`), paging (`$skip`, `$top`), projection (`$select`), and expansion (`$expand`). It can operate as a standalone server, an Express router, or a Node.js stream. The package is currently at version 0.3.0, with its last update more than seven years ago (as of April 2026), indicating it is no longer actively maintained. Due to its abandoned status, it's not recommended for new projects or production use.
