Introduction to TypeORM ORM for nodejs for databases2:13
Discover TypeORM, a Node.js ORM for databases, and learn to define entities, migrations, and relationships with NestJS or Express using active record and data mapper patterns through hands on examples.
Course Agenda for nodejs with TypeORM1:57
Pair TypeORM with Prisma to explore architecture, active record and data mapper patterns, core concepts like data source, entity, repository, migrations, and relationships such as one-to-one, one-to-many, many-to-many.
setup and installation tool needed for development2:19
Set up your development environment by installing Node.js (via nvm or direct) and Docker Desktop, then run Postgres, MongoDB, and MySQL in containers for exploring TypeORM with Express and TypeScript.
What is ORM and How it help developers4:19
Discover how TypeORM enables entity classes, repositories, and query builders to interface with databases, offering type safety, productivity, and cross-database support.
Nodejs TypeORM - Basic setup of TypeORM and Building Blocks2:43
Create a data source object, define entities, obtain a repository, and use a query builder to construct queries, with options to run plain raw queries via the data source.
Nodejs TypeORM - Introduction on TypeORM4:35
Explore TypeORM's flexible patterns, including data mapper and active record, and learn to create and manage entities, repositories, and migrations, plus connecting to PostgreSQL in NestJS or Express.
Nodejs TypeORM - TypeORM Setup and Configuration3:38
Learn how to set up a PostgreSQL database for a Node.js TypeORM project using Docker, including docker run and docker compose workflows, environment variables, and testing connections.
Nodejs TypeORM - TypeORM entities and Repository9:49
Bootstrap an express app with TypeORM to connect a Postgres database via a data source, using entity and repository patterns with environment config and a monorepo workspace, including table creation.
Nodejs TypeORM - ORM Entities and Tooling for Database2:37
Explore connecting to a Postgres database with TypeORM entities, migrations, and CLI tooling, configure via .env, bootstrap with Docker, visualize with TablePlus, and prepare an Express API using repositories.
Nodejs TypeORM - Express App CRUD APIs with TypeORM8:18
Set up an Express app with TypeORM to read and write data in Postgres, bootstrap a TypeScript project, configure data source and environment variables, and implement basic CRUD endpoints.
Nodejs TypeORM - Migration And TypeORM cli6:07
Explore how to use TypeORM CLI to manage migrations, create and run migration files for user and post tables, and safely handle schema sync and reversions.

TypeORM- Entities and running Migration6:27
Manage a monorepo with pnpm workspaces and define TypeORM entities for user, product, and company. Learn migrations, sync true, data source initialization, and repository CRUD operations.
Monorepo Setup and Using Project Examples inside PMPM workpsace4:49
Set up a monorepo with a pnpm workspace and symlinks to share dependencies across projects. Learn repository pattern with TypeORM in NestJS and Express TypeScript, including entities and data source.
TypeORM - Extend Repository Pattern for DAO services5:25
Learn to implement an extendable TypeORM repository pattern in a layered Express TypeScript project, building a user repository with custom methods like find active user, by email, and pagination.
TypeORM - Express CRUD App development and code Organise8:52
Demonstrate building a simple Express TypeScript app with TypeORM, outlining a folder structure (routes, controllers, services, middleware), data source setup, entity creation, and basic CRUD operations.
TypeORM - Express App Demo with APIs3:18
Demonstrates a TypeORM express app with a docker container running postgres, exposing CRUD APIs for a users table, documented via swagger and postman, using development mode synchronization.
TypeORM - Adding Migration and Running Migration using TypeORM CLI7:54
Learn to create and run migrations with the TypeORM CLI using migration files in a production workflow, and configure the data source to manage up and down changes safely.
TypeORM - Entity Relationships one-to-one, one-to-many5:43
Learn TypeORM relationships: one-to-one, one-to-many, many-to-many, and many-to-one, mapped to foreign keys and join tables in the database via entities like user, profile, post, and tag.
TypeORM - Query Builder Examples8:18
Learn to use TypeORM query builder to craft custom queries with joins, aggregations, and subqueries across user and post entities, including select, where, group by, order by, pagination, and updates.
TypeORM - NodeJS APIs soft delete Operations2:26
Master soft delete in TypeORM by marking records with a deleted_at timestamp instead of permanently deleting them. Explore querying, restoring soft deleted records, including with_deleted and only_deleted.
TyepORM - Integration with Nestjs Nodejs Framework6:01
Explore integrating TypeORM with the NestJS framework, wiring TypeORM module with env-based config, entities like user, post, author, and repository injection for CRUD in a NestJS app.
TypeORM - Transaction and Managing Transactions different ways3:46
Explore three approaches to TypeORM 3.x transactions: using the transaction manager, using a query runner, and relying on auto commit with try/catch for automatic rollback.

Requirements

Basic knowledge of JavaScript or Node.js
No prior database or ORM experience required
Node.js installed on your system
docker is optional, good if you have

Description

Databases are a core part of every real-world Node.js application.
If you already know Node.js but feel unsure when working with SQL databases, relationships, or ORMs, this course is designed for you.

In this hands-on course, you will learn TypeORM from scratch and use it to build production-ready Node.js backend applications using SQL databases such as PostgreSQL, MySQL, and SQLite.

This course focuses on practical backend development. You will work with real database schemas, understand how ORMs work internally, manage database migrations, write optimized queries, and apply best practices used in modern backend systems.

By the end of the course, you will be confident designing, querying, and managing databases in Node.js using TypeORM.

What Will Students Learn?
“This course prepares you for real-world backend development and professional Node.js projects.”

Students will be able to:

Understand how SQL databases work with Node.js
Connect Node.js applications to databases using TypeORM
Design entities, columns, and database schemas
Work with PostgreSQL, MySQL, and SQLite
Perform CRUD operations using repositories and QueryBuilder
Implement One-to-One, One-to-Many, and Many-to-Many relationships
Create and manage database migrations
Use transactions and handle complex queries
Optimize database performance and queries
Structure production-ready backend projects

Who this course is for:

Node.js developers who want to master SQL databases
Backend developers using Express or NestJS
JavaScript developers moving into backend development
Developers confused by ORMs and database relationships
Developers preparing for backend interviews
