GROQ specification

👉🏻 Published versions of the spec can be viewed here.

This is the specification for GROQ (Graph-Relational Object Queries), a query language and execution engine made at Sanity.io, for filtering and projecting JSON documents. The work started in 2015, and the development of this open standard started in 2019. Read the announcement blog post to understand more about the specification process and see the getting started guide to learn more about the language itself.

Tools and resources for GROQ

• Syntax highlighting in VS Code.
• Syntax highlighting in Sublime Text.
• GROQ tagged template literal, for writing GROQ queries in JavaScript files.
• groq-cli, a command-line tool for running GROQ on files and URLs.
• groq-js, a JavaScript implementation of GROQ.
• Go GROQ library, a Go implementation of the GROQ parser.
• groqfmt, a command-line formatter for GROQ, written in Go.

Development of the specification

The specification is written using spec-md, a Markdown variant optimized for writing specifications. The source is located under the spec/-directory which is then converted into HTML and presented at https://spec.groq.dev. To ensure that implementations are compatible we write test cases in the GROQ test suite.

The specification follows the versioning scheme of GROQ-X.revisionY where X (major) and Y (revision) are numbers:

• The first version is GROQ-1.revision0.
• Later revisions are always backwards compatible with earlier revisions in the same major version.
• Revisions can include everything from minor clarifications to whole new functionality.
• Major versions are used to introduce breaking changes.
