Define entities once in TypeORM, get spec-compliant OData v4 automatically
OData (Open Data Protocol) is a standardized REST protocol for queryable APIs, backed by OASIS and used by Microsoft, SAP, and enterprise clients. It defines conventions for filtering, sorting, pagination, and metadata — so clients and servers speak the same language.
Auto-derive EDM from TypeORM entities. No manual OData schema maintenance.
Built from the OASIS OData v4 ABNF grammar. Responses pass OData validation.
Works with NestJS decorators, guards, pipes, and interceptors. Mix OData and REST routes freely.
Lambda any/all, arithmetic operators, date/time functions, string functions — all translated to parameterized SQL.
Multi-operation batch requests with atomic changesets. Zero additional setup when using ODataTypeOrmModule.
maxTop, maxExpandDepth, maxFilterDepth limits enforced server-side. Parameterized queries prevent SQL injection.
