Designing the ultimate TypeScript query builder

The text discusses the design and implementation of a TypeScript query builder that can express queries of arbitrary complexity while automatically inferring return types. It is based on EdgeQL, an object-oriented query language designed as a spiritual successor to SQL. The query builder provides the best of both worlds: the type safety of an ORM coupled with the expressive power of a full-fledged query language. Key features include inserting objects, nested inserts, selecting objects, adding computed properties, filters, ordering and pagination, updating objects, self-referential updates, and composing queries. The text also compares the query builder to ORMs and highlights its superior expressive power and functionality.
