What is @prisma/client?
The @prisma/client package is an auto-generated and type-safe query builder that's tailored to your data model. It's part of the Prisma ORM and is designed to make database access easy and intuitive in Node.js and TypeScript applications.
What are @prisma/client's main functionalities?
Fetching data
This feature allows you to fetch data from the database. The code sample demonstrates how to retrieve all records from the 'user' table.
const users = await prisma.user.findMany();
Creating data
This feature is used to create new records in the database. The code sample shows how to create a new user with a name and email.
const user = await prisma.user.create({ data: { name: 'Alice', email: 'alice@example.com' } });
Updating data
This feature allows you to update existing records in the database. The code sample demonstrates updating the name of a user with a specific ID.
const updateUser = await prisma.user.update({ where: { id: 1 }, data: { name: 'Bob' } });
Deleting data
This feature enables you to delete records from the database. The code sample shows how to delete a user with a particular ID.
const deleteUser = await prisma.user.delete({ where: { id: 1 } });
Other packages similar to @prisma/client
sequelize
Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite, and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication, and more. Compared to @prisma/client, Sequelize has been around for longer and has a wider adoption, but Prisma offers a more modern approach with a focus on type safety and ease of use.
typeorm
TypeORM is an ORM that can run in Node.js, Browser, Cordova, PhoneGap, Ionic, React Native, NativeScript, Expo, and Electron platforms and can be used with TypeScript and JavaScript (ES5, ES6, ES7, ES8). It's heavily influenced by other ORMs, such as Hibernate, Doctrine, and Entity Framework. TypeORM provides a similar level of abstraction as @prisma/client but with a different API and philosophy, focusing more on the data-mapper pattern.
knex
Knex.js is a 'batteries included' SQL query builder for Postgres, MSSQL, MySQL, MariaDB, SQLite3, Oracle, and Amazon Redshift designed to be flexible, portable, and fun to use. It provides the building blocks for setting up a database schema and writing queries. While Knex doesn't offer the same level of abstraction or type safety as @prisma/client, it is a powerful query builder that's been widely used in the Node.js community.
