sqliteTable infer optional vs required fields

I am trying to create optional fields on my model but no matter what I do the drizzle is inferring all the properties as required. See the example below:

const example = sqliteTable("example", {
  id: text("id").primaryKey(),
  required: text("required").notNull(),
  optional: text("optional"),
});

type NewExample = typeof example.$inferInsert;
// resolves in:
// type NewExample = {
//   id: string;
//   required: string;
// }

type Example = typeof example.$inferSelect;
// resolves in:
// type Example = {
//   id: string;
//   required: string;
//   optional: string;
// }

// my expectation:
// type Example = {
//   id: string;
//   required: string;
//   optional?: string;
// }
//
// or
//
// type Example = {
//   id: string;
//   required: string;
//   optional: string | undefined;
// }

const example = sqliteTable("example", {
  id: text("id").primaryKey(),
  required: text("required").notNull(),
  optional: text("optional"),
});

type NewExample = typeof example.$inferInsert;
// resolves in:
// type NewExample = {
//   id: string;
//   required: string;
// }

type Example = typeof example.$inferSelect;
// resolves in:
// type Example = {
//   id: string;
//   required: string;
//   optional: string;
// }

// my expectation:
// type Example = {
//   id: string;
//   required: string;
//   optional?: string;
// }
//
// or
//
// type Example = {
//   id: string;
//   required: string;
//   optional: string | undefined;
// }

Is there any way to achieve expected behaviour with the drizzle orm?

👋 Can you share your ts config?

Check if you have strict to true

Seems that strict is unrelated to this since it is used for push as stated here: https://orm.drizzle.team/kit-docs/config-reference#strict Nevertheless this is my config:

import type { Config } from "drizzle-kit";

export default {
  schema: "./src/app/schema.ts",
  out: "./db/migrations",
  dialect: "sqlite",
  dbCredentials: {
    url: "./data.db",
  },
} satisfies Config;

import type { Config } from "drizzle-kit";

export default {
  schema: "./src/app/schema.ts",
  out: "./db/migrations",
  dialect: "sqlite",
  dbCredentials: {
    url: "./data.db",
  },
} satisfies Config;

Also here are my drizzle versions:

oh sorry I mean strict in your tsconfig file

{
  "compilerOptions": {
    "strict": true, // this
    ...
  }
}

{
  "compilerOptions": {
    "strict": true, // this
    ...
  }
}

Perfect! That's exactly what I was missing. Thank you very much. Do I mark this thread as resolved now or something?
