Schema Comparison

This feature allows you to compare two GraphQL schemas and detect changes between them. The code sample demonstrates how to use the `diff` function to find differences between an old schema and a new schema.

const { diff } = require('@graphql-inspector/core');
const oldSchema = `type Query { hello: String }`;
const newSchema = `type Query { hello: String, goodbye: String }`;
const changes = diff(oldSchema, newSchema);
console.log(changes);

Schema Validation

This feature helps you validate a GraphQL schema to ensure it adheres to the GraphQL specification. The code sample shows how to use the `validate` function to check a schema for errors.

const { validate } = require('@graphql-inspector/core');
const schema = `type Query { hello: String }`;
const errors = validate(schema);
console.log(errors);

Schema Coverage

This feature allows you to check how well your GraphQL queries cover your schema. The code sample demonstrates how to use the `coverage` function to analyze the coverage of a schema based on provided documents.

const { coverage } = require('@graphql-inspector/core');
const schema = `type Query { hello: String }`;
const documents = [{ content: `{ hello }` }];
const result = coverage(schema, documents);
console.log(result);
