Mastering Database Management with Knex.js and PostgreSQL

Define database migrations as version control for your PostgreSQL schema with specific instructions to create or alter tables, enabling team collaboration, sharing changes, and consistent deployment with apply and rollback.

initialize the next cli, create and run migrations with typescript, and define authors, genres, and books tables with foreign keys and timestamps in postgresql.

Seed a database by populating it with initial data for testing and development, including sample records, default settings, and reference data.

Create a TypeScript types folder with interfaces for author, genre, and book, then link them into a module that defines tables to enable autocomplete and typed returns.

Seed authors and books with Next Seed, TypeScript, and Faker; generate author bios and book details, and ensure order by renaming seeds to run genres first, then authors, then books.

Explore read operations in knex and PostgreSQL after seeding; retrieve authors and books with limit, offset, and order by, using query binding and first to fetch a single record.

Learn create operations for authors and books in knex.js with PostgreSQL, including inserting records, using returning, and validating author and genre IDs before insertion.

Learn how to perform update operations with Knex.js and PostgreSQL by updating authors and books, validating IDs, handling optional foreign keys, and returning updated records.

Learn to perform delete operations in knex.js with postgresql, validating existence, handling foreign-key constraints, and safely deleting books and authors.

Master advanced knex queries with joins to fetch books by author and genre, use group by and count for author totals, apply order by, limits, and transactions.

Explore how to implement transactions in Knex.js with PostgreSQL, creating an author and a book within a single transaction that commits on success and rolls back on error.

Explore the Knex.js query builder to implement pagination with limit and offset, return the author results and total count, and demonstrate cloning and clearing statements for reuse.

Learn end-to-end database management with Knex.js and PostgreSQL: set up the next CLI, run migrations and seeds, implement CRUD with validation, and explore joins, relations, transactions, and advanced query building.
