Remarks

Kysely database schema type definition

const role = enumType("role", ["admin", "user"]);
const roleColumn = enumerated(role);
type RoleColumn = {
  readonly __select__: "admin" | "user" | null;
  readonly __insert__: "admin" | "user" | null | undefined;
  readonly __update__: "admin" | "user" | null;
};

Nullability and optionality will change according to the column's constraints, generated values, and default data values.

Zod Schema

Types:

// enumType("role", ["admin", "user"]);
{
  input?: "admin" | "user" | null | undefined;
  output?: "admin" | "user" | null | undefined;
}

Nullability and optionality will change according to the column's constraints, generated values, and default data values.

Validations:

• Explicit undefined values are rejected.
• Input values must be an enum value, or null.

Example

import { enumerated, enumType, schema, table } from "monolayer/pg";
import { zodSchema } from "monolayer/zod";

const role = enumType("role", ["admin", "user"]);
const dbSchema = schema({
  types: [role],
  tables: {
    example: table({
      columns: {
        role: enumerated(role),
      },
    }),
  },
});

// Kysely database schema type
type DB = typeof dbSchema.infer;
// Zod Schema
const schema = zodSchema(database.tables.example);
