Tools Required For building APIS2:11
Creating and Running First Project in NestJS6:28
Install the nestjs cli globally, scaffold a new nest project with nest new, then run npm run start or npm run start dev for updates and view at localhost 3000.
Breaking Down the Basic NestJS Project Structure4:00
An Abstract overview of How Entire NestJS App is Structured6:12
Discover how a NestJS application is structured, from app module, controller, and service to database access via an ORM or ODM (Prisma or Mongoose), handling requests and responses.

Creating a Module, Controller and Service Using Nest CLI5:26
Learn to scaffold a NestJS module with a controller and service using the Nest CLI, import it into the app module, and understand module, controller, and provider relationships.
Working With Controller, Passing Information through URL Params and Query String11:32
Learn how a NestJS controller handles http requests, implements get, post, put, patch, and delete endpoints, and passes data via url params and query strings using param and query decorators.
Handling Post and Put Request in Controller3:58
How to Work with Controller and Service Classes7:43

Mongo DB Connection and Creating Record in Database12:41
Connect a NestJS app to MongoDB using Mongoose, define a restaurant schema, inject the model into the service, and create a record with a database-backed API, returning 201.
What is DTO, Creating dto for restaurant5:54
DTO Validation Using Class Validator & Class Transformer4:16
Using Pipes Globally with Validators to Show Validation Messages to user8:35
Get All Records and Single Record Based on Id from MongoDB5:56
Fetch all restaurant records from MongoDB and return them to the controller. Fetch a single restaurant by ID, validate existence, and throw not found if missing.
Update and Delete Endpoint7:23
Implement delete and update endpoints in NestJS by validating a restaurant id before deleting or updating via the controller and service.

Organize and Share Your REST API Endpoints with Postman Collections3:58
Organize your NestJS api endpoints in Postman collections, create folders, save requests with meaningful names, and share collections with teammates for clear documentation.
Setup Swagger Docs in NestJS: POST Restaurant Endpoints7:41
Set up swagger UI in nestjs to generate interactive OpenAPI documentation for REST endpoints and expose docs at the docs path.
Swagger Docs: Completing POST Restaurant Endpoints6:18
Swagger Docs: GET, UPDATE & DELETE Restaurant Endpoints8:57

Requirements

Knowledge of JavaScript, TypeScript, NodeJs
Basic knowledge of Database like MongoDB
Basic Knowledge of API's & how they work
