Introduction to Prisma Generators

Prisma generators are a crucial component of the Prisma ORM (Object-Relational Mapping) system, allowing developers to specify what assets are generated when the prisma generate command is invoked. This article delves into the world of Prisma generators, exploring their configuration, types, and usage.

Configuring Generators

A Prisma schema can have one or more generators, represented by the generator block. The main property provider defines which Prisma Client (language-specific) is created. Currently, only prisma-client-js is available. Additionally, you can define a custom output folder for the generated assets using the output property.

generator client {
  provider = "prisma-client-js"
  output = "./generated/prisma-client-js"
}

Prisma Client: prisma-client-js

The generator for Prisma's JavaScript Client accepts multiple additional properties, including previewFeatures and binaryTargets. previewFeatures allows you to include preview features, while binaryTargets specifies the engine binary targets for prisma-client-js.

generator client {
  provider = "prisma-client-js"
  previewFeatures = ["sample-preview-feature"]
  binaryTargets = ["linux-musl"]
}

Binary Targets

Binary targets are used to define which files should be present for the target platform(s). The native binary target is special, as it detects the current operating system and automatically specifies the correct binary target.

• Native Binary Target: The native binary target is the default and can be set explicitly to include additional binary targets for deployment to different environments.
• Custom Binary Targets: You can specify custom binary targets, such as debian-openssl-1.1.x for Ubuntu 18+ or native for local development.

Community Generators

The Prisma community has created a wide range of generators to extend the functionality of the Prisma ORM. Some examples include:

• prisma-dbml-generator: Transforms the Prisma schema into Database Markup Language (DBML) for easy visual representation.
• prisma-docs-generator: Generates an individual API reference for Prisma Client.
• prisma-json-schema-generator: Transforms the Prisma schema into JSON schema.
• typegraphql-prisma: Generates TypeGraphQL CRUD resolvers for Prisma models.
• prisma-json-types-generator: Adds support for strongly typed JSON fields for all databases.

These community generators can be used to generate various assets, such as API documentation, JSON schema, and CRUD resolvers, making it easier to work with Prisma and improve development productivity.

Conclusion

Prisma generators are a powerful tool for customizing the Prisma ORM and extending its functionality. By understanding how to configure generators and utilizing the wide range of community-generated tools, developers can streamline their development process and improve the overall quality of their applications.
