OData V4 Server for Node.js

odata-v4-server is a Node.js library for building OData Version 4.0 compliant servers. It allows developers to expose OData services either as a standalone server, an Express router, or as a stream. The package facilitates defining service metadata using TypeScript decorators or a JSON schema, supporting standard OData features like query language parsing ($filter, $orderby, $top, $skip, $select, $expand, $count) and CRUD operations on entity sets. It also supports complex types, navigation properties, actions, and functions. Currently at version 0.2.13, its release cadence appears to be irregular as it's still in pre-1.0 development. A key differentiator is its extensive use of decorators for defining controllers and handling OData query parameters, streamlining the development of data services.
