Query Language

18 projects

This category is mostly about GraphQL, with a second group of libraries for querying JSON documents and parsing filter expressions in REST APIs. For GraphQL servers, the main decision is schema-first versus code-first: you either write the schema in SDL and generate Go code, or you build the schema from Go types and resolvers at runtime.

gqlgen from 99designs is schema-first and generates type-safe resolvers and models, which suits teams that want the compiler to catch schema mismatches. graphql-go/graphql is a code-first port of the reference graphql-js implementation, where you assemble the schema with Go structs. graph-gophers/graphql-go parses SDL and binds resolvers by method name, which keeps setup light. For JSON, gojsonq queries decoded data, jsonpath and jsonslice implement JSONPath, gnata implements JSONata, and dasel is a command-line tool for querying and updating JSON, YAML, TOML and XML. rql and rqp turn URL query parameters into filters for REST endpoints.

For a new GraphQL API, gqlgen is the most common pick because generated code is checked at compile time and resolvers are plain Go. Choose a code-first library if your schema is assembled dynamically. For JSON querying inside a program, prefer decoding into structs with encoding/json first, and use a query library only for documents whose shape you do not control.
