Description

Mastering NestJS – A Comprehensive Hands-on CourseMaster modern backend development with NestJS in this comprehensive Hindi course. Whether you’re a beginner or an experienced developer, this course will take you from zero to hero by covering everything from the basics to advanced enterprise-level concepts.You’ll learn how to build scalable, secure, and maintainable server-side applications using TypeScript and NestJS, a powerful Node.js framework inspired by Angular. We’ll explore topics like REST APIs, GraphQL, authentication, database integration (PostgreSQL, MongoDB, TypeORM, Prisma), monorepo architecture, microservices, event-driven systems, testing, cloud deployments, and more.By the end of this course, you’ll be confident enough to develop and deploy production-grade backend applications using best practices in modern development workflows.Section 1: Introduction – NestJS Zero to HeroLecture 1: NestJS Zero to Hero – Modern backend Development Lecture 2: Setting up Your System and prerequisite for this Course Lecture 3: Course Agenda & OutlineSection 2: Getting Started with NestJSLecture 4: NestJS CLI Starter: Exploring the Generated CodeLecture 5: System Setup and Node.js Installation for NestJS DevelopmentLecture 6: Why NestJS? – Introduction to NestJS (Preview enabled)Lecture 7: NestJS vs Express: Key Differences in API DevelopmentLecture 8: Using NestJS CLI & Organize Your Code with Modular StructureSection 3: NestJS Basic Fundamentals with Simple CRUDLecture 9: Baseline Nestjs Code for Building APIsLecture 10: Building REST API CRUD Operation with In Memory DataLecture 11: NestJS Controller and Service Basic FundamentalsSection 4: NestJS CLI and NestJS Core Building BlocksLecture 12: Understanding the NestJS Request Lifecycle FlowLecture 13: Kickstarting Your NestJS App with the CLI (Preview enabled)Lecture 14: NestJS Middleware and Auth Guard with Core ComponentsSection 5: NestJS Dependency Injection and Building BlocksLecture 15: NestJS API Documentation Using SwaggerCourse Modules (Extended Learning)Module 1: NestJS Fundamentals and Core ConceptsIntroduction to NestJS and its architectureBasic Fundamentals of Nestjs (core concepts)Setting up a NestJS project with TypeScriptCreating RESTful APIs and GraphQL endpointsImplementing authentication (JWT, OAuth, Passport.js)Building end to end REST API servicesSetting up a NestJS project with MonorepoDatabase integration with TypeORM & Prisma and MongooseSetting up a NestJS project with TestingUnderstanding NestJS MicroservicesBuilding Microservices and event-driven applicationsUnit & Integration Testing in NestJSCI/CD and deploying NestJS apps to the cloudModule 2: API Development – REST and GraphQLCreating RESTful APIs with NestJSBuilding GraphQL APIs using code-first and schema-first approachesAPI versioning and best practicesAPI documentation using SwaggerHandling GraphQL resolvers and decoratorsIntegrating GraphQL with authentication and guardsModule 3: Authentication and AuthorizationAuthentication with Passport.js (JWT, Local, OAuth2 strategies)Implementing cookie-based authentication (HTTP-only cookies)Session-based authentication flowRole-based access control (RBAC)Token-based authentication and refresh strategiesSecurity best practices (CORS, helmet, rate limiting, CSRF protection)Module 4: Database Integration and File HandlingConnecting PostgreSQL using TypeORMUsing Prisma ORM for modern data modelingIntegrating MongoDB with MongooseFile upload handling with Multer and working with static assetsException filters, interceptors, and custom decoratorsModule 5: NestJS Microservices and ArchitectureUnderstanding NestJS microservices architectureBuilding microservices using TCP, Redis, NATS, RabbitMQUsing message patterns and transportersCommunication using EventEmitter and custom event busesScalable job queues with BullMQDeploying and testing distributed servicesModule 6: NestJS GraphQL Deep DiveSetting up GraphQL modules and resolversWorking with GraphQL decorators and schemasUsing Apollo Server and code-first approachHandling GraphQL mutations and queries with DTOsIntegrating GraphQL with databases (TypeORM/Prisma)Testing GraphQL queries and mutationsModule 7: NestJS Testing StrategiesUnit testing with Jest and mocking techniquesWriting integration tests with SupertestTesting GraphQL APIs and authentication guardsTesting modules and controllers independentlyCreating reusable testing utilitiesBest practices for test organization and coverageModule 8: DevOps, CI/CD, and Cloud DeploymentSetting up environment variables and configuration modulesLogging and monitoring with Winston and MorganCI/CD pipeline setup with GitHub Actions or GitLab CIDockerizing your NestJS app for productionDeploying to AWS Lambda using Serverless FrameworkDeploying on EC2, ECS, and KubernetesCreating and publishing custom NestJS packages
