Creating Node project with Express, MongoDB, Typescript & GraphQL <\/u><\/strong>involves several steps. Lets discuss them in detail as follows: Step 2: Initialize the project yarn add typescript ts-node @types\/node @types\/express @types\/graphql @types\/mongoose @types\/dotenv @types\/mongodb -D “compilerOptions”: {<\/p>\n\n\n\n “target”: “ES6”,<\/p>\n\n\n\n “module”: “commonjs”,<\/p>\n\n\n\n “strict”: true,<\/p>\n\n\n\n “esModuleInterop”: true,<\/p>\n\n\n\n “skipLibCheck”: true,<\/p>\n\n\n\n “forceConsistentCasingInFileNames”: true,<\/p>\n\n\n\n “outDir”: “.\/dist”,<\/p>\n\n\n\n “rootDir”: “.\/src”<\/p>\n\n\n\n },<\/p>\n\n\n\n “include”: [“src”],<\/p>\n\n\n\n “exclude”: [“node_modules”]<\/p>\n\n\n\n } PORT=4000 “start”: “nodemon –exec ts-node src\/index.ts”,<\/p>\n\n\n\n “build”: “tsc”,<\/p>\n\n\n\n “test”: “jest”<\/p>\n\n\n\n \u00a0 }, import dotenv from “dotenv”;<\/p>\n\n\n\n import connectDB from “.\/databse”;<\/p>\n\n\n\n import { ApolloServer } from “apollo-server-express”;<\/p>\n\n\n\n import usertypeDefs from “.\/schema\/userschema”;<\/p>\n\n\n\n import userresolvers from “.\/resolvers\/userResolvers”;<\/p>\n\n\n\n import UserModel from “.\/models\/usermodel”;<\/p>\n\n\n\n dotenv.config();<\/p>\n\n\n\n connectDB();<\/p>\n\n\n\n const startServer = async () => {<\/p>\n\n\n\n const app = express();<\/p>\n\n\n\n const server = new ApolloServer({<\/p>\n\n\n\n typeDefs: [usertypeDefs],<\/p>\n\n\n\n resolvers: [userresolvers],<\/p>\n\n\n\n context: {<\/p>\n\n\n\n UserModel,<\/p>\n\n\n\n },<\/p>\n\n\n\n });<\/p>\n\n\n\n await server.start();<\/p>\n\n\n\n server.applyMiddleware({ app });<\/p>\n\n\n\n var PORT = process.env.PORT;<\/p>\n\n\n\n app.listen(PORT, () => {<\/p>\n\n\n\n console.log(`Server running at http:\/\/localhost:${PORT}`);<\/p>\n\n\n\n });<\/p>\n\n\n\n };<\/p>\n\n\n\n startServer();<\/p>\n\n\n\n
Prerequisites:<\/strong>
Before getting into the steps to create a node project, let’s make sure the system is installed with node , VS Code, and Mongo DB softwares.
<\/u>
Step 1 : Create the server folder and navigate into it.
<\/strong>mkdir server
cd server<\/p>\n\n\n\n
<\/strong>yarn init -y
Step-3 : Install all packages with typescript dependencies
<\/strong>yarn add express graphql express-graphql mongoose dotenv mongodb cors<\/p>\n\n\n\n
Step 4: Setup config.ts file in the project root folder:
<\/strong>{<\/p>\n\n\n\n
Step 5: Setup .env file in the project root folder
<\/strong>MONGO_URI=mongodb:\/\/localhost:27017\/mydatabase<\/p>\n\n\n\n
Step 6: Create folders & files under the project root
<\/strong>mkdir src<\/p>\n\n\n\ntouch src\/index.ts src\/database.ts src\/schema.ts src\/models\/User.ts
Step 7: create database.ts file for DB connection
<\/strong>import express from 'express';<\/pre>\n\n\n\nimport dotenv from 'dotenv';<\/pre>\n\n\n\n
import connectDB from '.\/database';<\/pre>\n\n\n\n
dotenv.config();<\/pre>\n\n\n\n
const app = express();<\/pre>\n\n\n\n
const port = process.env.PORT || 4000;<\/pre>\n\n\n\n
connectDB();<\/pre>\n\n\n\n
app.listen(port, () => {<\/pre>\n\n\n\n console.log(`Server is running at http:\/\/localhost:${port}\/graphql`);<\/pre>\n\n\n\n});
Step 8: Update package.json<\/strong>
\u00a0 \"scripts\": {<\/pre>\n\n\n\n
Step 9: Create models, schemas, resolvers and update them in index.ts file:
<\/strong>import express from “express”;<\/p>\n\n\n\n
