GraphQL Reference

Work in progress - pull requests showing additional examples are strongly encouraged.


This page will walk you through a series of GraphQL queries, each designed to demonstrate a particular feature of GraphQL. You’ll be querying the real schema used on so feel free to experiment and poke around the innards of our site!

You’ll be using GraphiQL, an interactive editor you can also use while building your Gatsby site.

Basic query

Let’s start with the basics, pulling up the site title from your gatsby-config.js’s siteMetaData. Here the query is on the left and the results are on the right.

Try editing the query to include the description from siteMetadata. When typing in the query editor you can use Ctrl + Space to see autocomplete options and Ctrl + Enter to run the current query.

A longer query

Gatsby structures its content as collections of nodes, which are connected to each other with edges. In this query you ask for the total count of plugins in this Gatsby site, along with specific information about each one.

Try using the editor’s autocomplete (Ctrl + Space) to get extended details from the packageJson nodes.


There are several ways to reduce the number of results from a query. Here totalCount tells you there’s a few hundred results, but limit is used to show only the first two.


In this query filter and the ne (not equals) operator is used to show only results that have a title.

Gatsby relies on Sift to enable MongoDB-like query syntax for object filtering. This allows Gatsby to support operators like eq, ne, in, regex and querying nested fields through the __ connector

A good video tutorial on this is here.

TODO: Add more advanced examples


The ordering of your results can be specified with sort. Here the results are sorted in ascending order of frontmatter’s date field.

TODO: Can you sort on multiple fields?


Dates can be formatted using the formatString function.

TODO: Expand on the possibilities of formatting - which fields can be formatted? What are the available formatting options?

Sort, filter, limit & format together

This query combines sorting, filtering, limiting and formatting together.

Query variables

In addition to adding query arguments directly to queries, GraphQL allows to pass in “query variables”. These can be both simple scalar values as well as objects.

The query below is the same one as the previous example, but with the input arguments passed in as “query variables”.

To add variables to page component queries, pass these in the context object when creating pages.


You can also group values on the basis of a field e.g. the title, date or category and get the field value, the total number of occurences and edges.

The query below gets us all authors (fieldValue) who wrote a blogpost and how many blogposts (totalCount) they wrote. In addition we’re grabbing the title and slug of the author’s articles.

Where next?

Try running your own queries, check out the rest of the docs or run through the tutorial.
