Prisma is a tool for quick application development. It is a framework that allows you to automatize application development processes such as database support, authorization and data validation.
When we want to create a system based on a database approach with relational nature then we will use ORM (Object-Relational Mapping). In this article, I will introduce you to a library that helps you build an ORM.
What is Prisma?
Prisma is an open source ORM that helps you build apps faster and make fewer mistakes. Prisma takes a different approach to ORM compared to traditional ORMs. It uses a standard schema definition language (SDL) that automatically writes migrations and generates type-safe code. Prisma consists of the following parts:
- Prisma Client - It is an auto-generated and type-safe query builder for Node.js and TypeScript.
- Prisma Migrate - A migration system.
- Prisma Studio - GUI for viewing and editing data in the database.
Prisma Client - can be used in any Node.js or TypeScript app. It can be a REST API, GraphQL API, gRPC API or anything else that requires a database.
How does Prisma work?
Every project using Prisma starts with a Prisma schema file. A Prisma schema allows developers to define application models in an intuitive data modeling language. In such a schema, we usually configure three things:
- Data Source - Specifies the connection to the database (via an environment variable).
- Generator - Indicates what you want to generate.
- Data model - defines the application models.
A data model is a collection of models. A model has two main functions: It represents a table in relational databases or a collection in MongoDB and provides the basis for queries in the Prisma Client API.
Prisma installation
