echo "Starting server..." node server.js

app.use('/graphql', express.json(), expressMiddleware(server));

| Requirement | Version | Notes | |-------------|---------|-------| | Node.js | 16.x or higher | Required for npm/yarn installations | | npm | 8.x or higher | or yarn, pnpm | | GraphQL Server | Any | Express, Apollo, Yoga, etc. | | Modern Browser | Latest | Chrome, Firefox, Edge | 3.1 Method 1: Express Middleware (Most Common) Target: Adding GraphiQL to an existing Express.js GraphQL server. Step-by-step: # Create project directory mkdir my-graphql-app && cd my-graphql-app Initialize npm project npm init -y Install required packages npm install express graphql graphql-http npm install graphql-express Server Setup ( server.js ): const express = require('express'); const createHandler = require('graphql-http/lib/use/express'); const buildSchema = require('graphql'); // Build schema const schema = buildSchema( type Query hello: String ); graphiql install

const root = hello: () => 'Hello from GraphiQL!', version: () => '1.0.0' ;

Apollo Server v4 automatically serves GraphiQL when you visit the endpoint URL in a browser (no separate route needed). 3.3 Method 3: Standalone Desktop Application Target: Developers who want GraphiQL without a server. Installation Steps: | OS | Command / Action | |----|------------------| | macOS | brew install --cask graphiql | | Windows | Download .exe from GraphiQL Releases | | Linux (AppImage) | Download .AppImage , chmod +x , and run | Alternative: Run via npx (temporary) npx graphiql This opens a temporary GraphiQL instance at http://localhost:3000 that can connect to any GraphQL endpoint. 3.4 Method 4: Docker Deployment Target: Team environments or CI/CD pipelines. Dockerfile: FROM node:18-alpine WORKDIR /app echo "Starting server
