Type Alias: FromLixSchemaDefinition<T>

FromLixSchemaDefinition<T> = ApplyLixGenerated<T>

Convert a LixSchemaDefinition to a TypeScript type.

This type transformation:

  1. Converts JSON Schema properties to TypeScript types
  2. Wraps properties that declare defaults (default or x-lix-default) in LixGenerated markers
  3. Transforms type: "object" without properties to Record<string, any>

The resulting type can be used with LixInsertable, LixUpdateable, and LixSelectable for database operations.

Example

const AccountSchema = {
  "x-lix-key": "account",
  "x-lix-version": "1.0",
  "x-lix-primary-key": ["/id"],
  type: "object",
  properties: {
    id: { type: "string", default: "auto-generated" },
    name: { type: "string" },
    email: { type: "string" },
    metadata: { type: "object" },  // Becomes Record<string, any>
    created_at: { type: "string", "x-lix-default": "lix_now()" }
  },
  required: ["id", "name", "email"],
  additionalProperties: false
} as const satisfies LixSchemaDefinition;

type Account = FromLixSchemaDefinition<typeof AccountSchema>;
// Result: {
//   id: LixGenerated<string>;
//   name: string;
//   email: string;
//   metadata: Record<string, any> | undefined;
//   created_at: LixGenerated<string> | undefined;
// }
