@prisma-next/operations

Target-neutral operation registry for Prisma Next.

Overview

This package provides a generic, target-neutral operation registry. It's part of the core ring and has no dependencies on target-specific packages.

Responsibilities

• Operation Registry: Generic operation registry interface and implementation
  • OperationRegistry<T>: Generic interface for registering and iterating operations, parameterized by entry type
  • createOperationRegistry<T>(): Factory function to create operation registries
  • OperationEntry: Base entry type with args and returns
  • OperationDescriptor<T>: Entry plus a method name, used for registration
  • ParamSpec: Describes an operation parameter (codecId, nullable), used for both arguments and return values

Dependencies

• Depends on: Nothing (leaf package)
• Depended on by:
  • @prisma-next/sql-operations (extends with SQL-specific lowering specs)
  • @prisma-next/sql-relational-core (imports ParamSpec for AST and type definitions)
  • @prisma-next/sql-runtime, @prisma-next/framework-components, and other packages that build on the operation registry

Usage

Creating an Operation Registry

import { createOperationRegistry, type OperationDescriptor } from '@prisma-next/operations';

const registry = createOperationRegistry();

const descriptor: OperationDescriptor = {
  method: 'cosineDistance',
  args: [{ codecId: 'pg/vector@1', nullable: false }],
  returns: { codecId: 'pg/float8@1', nullable: false },
};

registry.register(descriptor);
const entries = registry.entries(); // Record<string, OperationEntry>

Using a Custom Entry Type

import { createOperationRegistry, type OperationEntry, type OperationDescriptor } from '@prisma-next/operations';

interface MyEntry extends OperationEntry {
  readonly extra: string;
}

const registry = createOperationRegistry<MyEntry>();

registry.register({
  method: 'myMethod',
  args: [],
  returns: { codecId: 'pg/int4@1', nullable: false },
  extra: 'custom data',
});
