What is @graphql-tools/optimize?
The @graphql-tools/optimize package is designed to optimize GraphQL schemas and queries. It provides functionalities to simplify and enhance the performance of GraphQL operations by removing unnecessary fields, types, and directives, and by optimizing query execution.
What are @graphql-tools/optimize's main functionalities?
Optimize GraphQL Schema
This feature allows you to optimize GraphQL documents based on a given schema. It removes unused fragments and fields that are not required for the queries to execute, which can lead to performance improvements in query execution.
import { optimizeDocuments } from '@graphql-tools/optimize';
import { parse, print } from 'graphql';
const schema = parse(`type Query { hello: String }`);
const documents = [parse(`query { hello }`)];
const optimizedDocuments = optimizeDocuments(schema, documents);
console.log(print(optimizedDocuments[0]));
Remove Unused Types
This feature optimizes the GraphQL schema by removing types that are not used in any of the operations. This can help in reducing the size of the schema and improving the load times and performance of GraphQL servers.
import { optimizeSchema } from '@graphql-tools/optimize';
import { makeExecutableSchema } from '@graphql-tools/schema';
const schema = makeExecutableSchema({ typeDefs: `type Query { hello: String } type Unused { id: ID }` });
const optimizedSchema = optimizeSchema(schema);
console.log(optimizedSchema.getTypeMap());
Other packages similar to @graphql-tools/optimize
graphql-query-complexity
This package provides a way to analyze and limit the complexity of GraphQL queries, based on configurable rules. It is similar to @graphql-tools/optimize in that it helps improve the performance of GraphQL APIs by preventing overly complex queries from being executed.
graphql-tools
While primarily focused on building and mocking GraphQL schemas, graphql-tools also includes some features for optimizing schemas, similar to @graphql-tools/optimize. However, it covers a broader range of functionalities including stitching and merging schemas, which is not the primary focus of @graphql-tools/optimize.
