CamelCase to snake_case

By default, table and column names defined in your schema will keep the same name.

For example, with this schema defintion:

import { table, text } from "@monolayer/pg/schema";

const usersTable = table({ 
  columns: {
    firstName: text(), 
  },
});

export const dbSchema = schema({
  tables: {
    usersTable,
  },
});

The table name in the database will be usersTable, and the column in the usersTable will be named firstName.

You can convert those names to snake_case at the database level by setting camelCase to true when defining the database:

databases.ts

import { defineDatabase } from "@monolayer/pg/schema";
import { dbSchema } from "./schema";

export default defineDatabase({
  schemas: [dbSchema],
  camelCase: true, 
});

Generating and applying migrations, will convert table and column names to snake_case:

• The table name in the database will be users_table
• The column in the users_table will be named first_name.

WARNING

You should set the camelCase option before generating and applying migrations to the database. Changing the option after having applied migrations will lead to a broken state.
