Graph Exploration

As your graph grows, understanding its structure can become more difficult. Without understanding a schema's intricacies—particularly how subgraphs relate to one another—development can become blocked or take wrong turns.

GraphOS Studio features

GraphOS Studio provides several ways of understanding and exploring your organization's graphs, including:

• An editable README page that describes the graph to newcomers
• The Schema page, which includes three distinct views, including schema visualization
• The Explorer, which helps you build new operations against your graph
• The Changelog, which displays all published changes

Viewing graph pages

After selecting an organization in GraphOS Studio, click a particular graph variant to view its pages.

Page permissions

With Serverless and Dedicated plans, all Studio organization members have access to all pages, including Settings for all graphs within the organization. Enterprise accounts can set member roles to configure fine-grained access for individual members of their organization.

The README page

When a user opens one of your graph's variants in GraphOS Studio, its README page appears:

Like the typical homepage for a Git repository, this page displays a Markdown-based README that you can edit with any content you like.

Each variant has its own README. If you edit one variant's README, those edits aren't applied to other variants. Among other uses, this enables you to provide different information to external consumers in a public variant.

Supported Markdown

The README supports all basic Markdown syntax and most extended syntax, including tables, code blocks, and footnotes.

You can define a GraphQL code block with the following syntax:

1
```graphql
2
query MyQuery {
3
  users {
4
    id
5
    name
6
  }
7
}
8
```

This renders the code block with buttons to copy an operation or open it in the Explorer.

README shortcodes

The README supports a set of shortcodes. These shortcodes can populate the README with data specific to your variant, like the graph's name and the variant's graph ref:

1
# Overview of {{ graph.name }}
2

3
Graph ref: {{ graph.ref }}

For a list of all supported shortcodes, click Graph shortcodes in the bottom-left corner of the README editor.

The Schema page

A graph variant's Schema page has three distinct views:

• The Reference tab lets you filter your schema's type and field definitions
• The SDL tab displays your schema's raw SDL
• The Visualization tab provides a filterable, navigable, graphical representation of your schema

Schema reference

The Reference tab on the Schema page lists the different kinds of definitions in your schema, for example, objects, scalars, interfaces, etc.

Select a kind of definition to view a table of all corresponding types:

Each type definition in the table includes:

• The type's name
  • You can click the name to view additional details for the type, such as fields for an object, or possible types for a union.
• The type's description, if your schema includes one
• Which subgraphs define the type, if you have a federated supergraph
  • Users with the Consumer role can't view subgraph details.

Filtering your schema

The top of the Schema page provides a Filter Schema box you can use to find types and fields that match a set of filters:

Any filters you set remain active as you move between definitions on the Schema page.

You can filter your schema definitions by type/field name, as shown above, along with any combination of the following:

Filtering rules

• If you list multiple possible values in a single filter, those values use OR logic.
  • For example, if you filter by subgraph:products,reviews the result includes definitions from each subgraph.
• If you apply multiple types of filters, those filters use AND logic.
  • For example, if you filter by subgraph:products and returnType:Int, the result includes only definitions that fulfill both criteria.
• Currently, it isn't possible to use AND logic for multiple filters of the same type.
  • For example, it isn't possible to filter by subgraph:products AND subgraph:reviews to include only definitions that are present in both subgraphs.

Schema definition language

The SDL tab displays the raw schema definition language (SDL) for each schema associated with your graph. For a monograph, this is simply the graph's API schema. Supergraphs also include a supergraph schema and subgraph schemas. See Viewing subgraph SDL for more information.

Regardless of the SDL type you're viewing, you can Copy the SDL or download it in Raw or JSON format from this tab.

Schema visualization

The Visualization tab provides a graphical representation of your schema's structure, including types, fields, and relationships. It can help clarify your understanding of your schema's design, so you can more easily identify potential issues and improve your data model.

The Explorer

GraphOS Studio provides a powerful Explorer IDE that helps you visualize your graph and run queries against it. It's available from your graph's Explorer page in Studio. Refer to the Explorer docs to learn more.

Tracking schema changes

The Changelog page in Studio displays a timeline of changes made to your graph's schema. Only schema changes that you publish to Studio are in this timeline, which is one of the most important reasons to include schema publishing in your continuous delivery pipeline.
