The Prisma Layer primarily refers to the `PrismaExtension` class, a build extension designed for the Trigger.dev platform. Its main purpose is to automate the discovery, generation, and deployment of the Prisma client and schema within a build process, especially when the Prisma schema is sourced from a published package like `@trycompai/db`. This layer ensures that the correct Prisma client is generated both locally during development and within the deployment environment, handling schema resolution, dependency management, and environment variable configuration for database connections. It abstracts away the complexities of integrating Prisma into a serverless or containerized build pipeline. ## PrismaExtension Overview The `PrismaExtension` class is a core component that integrates Prisma into the build process. It implements the `BuildExtension` interface, providing hooks for `onBuildStart` and `onBuildComplete` to manage Prisma-related tasks. ### Configuration Options The behavior of the `PrismaExtension` can be customized through the `PrismaExtensionOptions` interface. | Option Name | Type | Description | | :------------------- | :------- |
