• Unit & Integration Test Cases

Core NPM Module

• express, @types/express
• @types/node
• typescript
• dotenv
• cors
• helmet
• http-status-codes
• winston, @types/winston

Start the application

Start The application in Development Mode

• Clone the Application git clone https://github.com/santoshshinde2012/node-boilerplate.git
• Install the dependencies npm install
• Start the application npm run start:local

Start The application in Production Mode

• Install the dependencies npm install
• Create the build npm run build
• Start the application npm run start:production
• Before starting make sure to creat prod environment .env.prod file

Project Structure

Workflow

Encryption

Set the APPLY_ENCRYPTION environment variable to true to enable encryption.

Global Environment Object

You can directly access the environment attributes in any component/file using global environment object. For more details please check file src/global.ts.

Example

To access the applyEncryption attribute from Envionment class to Response Handler, write environment.applyEncryption;

Swagger API Documentation

The swagger documentation is available at the following url ${host}/docs:

http://localhost:3146/docs

Default System Health Status API

• ${host}/api/status/system - Return the system information in response
• ${host}/api/status/time - Return the current time in response
• ${host}/api/status/usage - Return the process and system memory usage in response
• ${host}/api/status/process - Return the process details in response
• ${host}/api/status/error - Return the error generated object in response

• Setup Eslint Prettier and Husky in Node JS Typescript Project

Notes

1. Why is my git pre-commit hook not executable by default?

• Because files are not executable by default; they must be set to be executable.

chmod ug+x .husky/*
chmod ug+x .git/hooks/*

2. Production Best Practices: Security

• Don’t use deprecated or vulnerable versions of Express
• Use TLS
• Use Helmet
• Use cookies securely
• Prevent brute-force attacks against authorization
• Ensure your dependencies are secure
• Avoid other known vulnerabilities
• Additional considerations

3. Tutorials

• Skeleton for Node.js Apps written in TypeScript (with Setup Instructions for ESLint, Prettier, and Husky)
• Global Error and Response Handler in Node JS with Express and Typescript
• Testing with Jest in TypeScript and Node.js for Beginners
• Static Code Analysis for Node.js and TypeScript Project using SonarQube
• Visualization of Node.js Event Emitter
