Batch Execution

This feature allows you to batch multiple GraphQL operations and execute them together. The code sample demonstrates creating a simple schema and batching two queries ('{ hello }' and '{ world }') for execution.

const { batchExecute } = require('@graphql-tools/batch-execute');
const { makeExecutableSchema } = require('@graphql-tools/schema');
const { graphql } = require('graphql');

const typeDefs = `
  type Query {
    hello: String
    world: String
  }
`;

const resolvers = {
  Query: {
    hello: () => 'Hello',
    world: () => 'World'
  }
};

const schema = makeExecutableSchema({ typeDefs, resolvers });

const operations = [
  { query: '{ hello }' },
  { query: '{ world }' }
];

batchExecute({ schema, operations }).then(results => {
  console.log(results);
});

Custom Execution Context

This feature allows you to provide a custom execution context for the batched operations. The code sample demonstrates how to pass a context object containing user information to the batchExecute function.

const { batchExecute } = require('@graphql-tools/batch-execute');
const { makeExecutableSchema } = require('@graphql-tools/schema');
const { graphql } = require('graphql');

const typeDefs = `
  type Query {
    hello: String
    world: String
  }
`;

const resolvers = {
  Query: {
    hello: () => 'Hello',
    world: () => 'World'
  }
};

const schema = makeExecutableSchema({ typeDefs, resolvers });

const operations = [
  { query: '{ hello }' },
  { query: '{ world }' }
];

const context = { user: { id: 1, name: 'John Doe' } };

batchExecute({ schema, operations, context }).then(results => {
  console.log(results);
});
