@graphql-inspector/commands

What is @graphql-inspector/commands?

@graphql-inspector/commands is a toolset for inspecting, validating, and comparing GraphQL schemas. It helps developers ensure the integrity and compatibility of their GraphQL APIs by providing various commands to check for changes, validate schemas, and more.

What are @graphql-inspector/commands's main functionalities?

Schema Diff

The `diff` command allows you to compare two GraphQL schemas and identify the differences between them. This is useful for understanding what has changed between schema versions.

const { diff } = require('@graphql-inspector/commands');

const oldSchema = `type Query { hello: String }`;
const newSchema = `type Query { hello: String, goodbye: String }`;

const result = diff(oldSchema, newSchema);
console.log(result);

Schema Validation

The `validate` command checks a GraphQL schema for errors and inconsistencies. This helps ensure that the schema is correctly defined and adheres to GraphQL specifications.

const { validate } = require('@graphql-inspector/commands');

const schema = `type Query { hello: String }`;
const result = validate(schema);
console.log(result);

Schema Coverage

The `coverage` command analyzes how well your GraphQL queries cover your schema. This helps identify parts of the schema that are not being used or tested.

const { coverage } = require('@graphql-inspector/commands');

const schema = `type Query { hello: String }`;
const documents = [{ query: `{ hello }` }];

const result = coverage(schema, documents);
console.log(result);
