@mirco312312/nest-fgql NPM

nest-fgql

A fast and lightweight module to expose GraphQL APIs in a NestJS application.

Description

This is intended to be a drop-in replacement for @nestjs/graphql that offers improved runtime performance.

Benchmarks show that Apollo adds a noteable overhead regarding performance. Using fastify and graphql-jit via fastify-gql performance is improved.

Usage

Requirements

Must first follow the Performance (Fastify) guide to setup fastify.

Install

yarn add @mirco312312/nest-fgql

Code

import { Module } from '@nestjs/common';
import { FgqlModule } from '@mirco312312/nest-fgql';
// ... your other imports

@Module({
  imports: [
    // ... preceeding modules
    FgqlModule.forRoot({
      autoSchemaFile: true,
      // ... any other options
    }),
    // ... more modules
  ],
})
export class ApplicationModule {}
