FQL language reference

The FQL language reference document describes the FQL syntax and the fundamentals of using the language to query Fauna.

FQL features a TypeScript-inspired syntax, which is extended to support concise relational queries and is, optionally, statically typed. This gives you a developer language that empowers you to write clear, concise queries and transactional code. A TypeScript-inspired database language is purpose-fit for Fauna. The resulting FQL syntax is familiar and easy to learn and scales to handle complex business logic, making it easy to realize the power of the Fauna operational database architecture.

Unlike well-known relational query languages, which are keyword-heavy and require learning a new syntax for every feature, FQL has a small core syntax with dedicated shorthand for common query concepts, such as record predicates and projection.

Occasionally, you might want to port a query from one context to another, such as interactively developing the query in the dashboard shell and copying it to your application code or applying your FQL knowledge in a different host programming environment. FQL has a dedicated syntax that applies to all contexts in which it exists, with drivers that implement a secure, string-based template system for embedded queries. This means that you can apply the same query syntax everywhere.
