@graphql-mesh/utils

What is @graphql-mesh/utils?

@graphql-mesh/utils is a utility package that provides a set of helper functions and tools to facilitate the development and integration of GraphQL Mesh. It includes various utilities for schema manipulation, data transformation, and other common tasks needed when working with GraphQL Mesh.

What are @graphql-mesh/utils's main functionalities?

Schema Manipulation

This feature allows you to merge multiple GraphQL schemas into a single schema. The code sample demonstrates how to use the `mergeSchemas` function to combine two schema objects.

const { mergeSchemas } = require('@graphql-mesh/utils');

const schema1 = /* GraphQL schema object */;
const schema2 = /* Another GraphQL schema object */;

const mergedSchema = mergeSchemas({ schemas: [schema1, schema2] });

Data Transformation

This feature provides utilities for transforming data. The code sample shows how to use the `transformData` function to apply a transformation function to a data object.

const { transformData } = require('@graphql-mesh/utils');

const data = { name: 'John Doe', age: 30 };
const transformation = (data) => ({ ...data, age: data.age + 1 });

const transformedData = transformData(data, transformation);

Error Handling

This feature offers utilities for handling errors in a consistent manner. The code sample demonstrates how to use the `handleError` function to manage errors that occur during operations.

const { handleError } = require('@graphql-mesh/utils');

try {
  // Some operation that might throw an error
} catch (error) {
  handleError(error);
}

Other packages similar to @graphql-mesh/utils

graphql-tools

graphql-tools is a package that provides a set of utilities for building and manipulating GraphQL schemas. It offers similar functionalities to @graphql-mesh/utils, such as schema stitching and transformation, but is more focused on schema creation and server-side tools.

apollo-server

apollo-server is a community-driven, open-source GraphQL server that works with any GraphQL schema. While it provides some utilities for schema manipulation and data handling, its primary focus is on serving GraphQL APIs, unlike @graphql-mesh/utils, which is more utility-focused.

graphql-compose

graphql-compose is a toolkit for generating complex GraphQL schemas on Node.js. It provides schema manipulation and transformation utilities similar to @graphql-mesh/utils, but it is more focused on schema generation and composition.
