Drizzle Kit provides a CLI command to introspect your database and generate a schema file with migrations. The schema file contains all the information about your database tables, columns, relations, and indices.
For example, you have such table in your database:
CREATE TABLE `users_table` (
`id` integer PRIMARY KEY AUTOINCREMENT NOT NULL,
`name` text NOT NULL,
`age` integer NOT NULL,
`email` text NOT NULL UNIQUE
);
Pull your database schema:
npx drizzle-kit pull --init
The result of introspection will be a schema.ts file, meta folder with snapshots of your database schema,
sql file with the migration and relations.ts file for relational queries.
Here is an example of the generated schema.ts file:
// table schema generated by introspection
import {
sqliteTable,
uniqueIndex,
integer,
text,
} from "drizzle-orm/sqlite-core";
export const usersTable = sqliteTable(
"users_table",
{
id: integer().primaryKey({ autoIncrement: true }).notNull(),
name: text().notNull(),
age: integer().notNull(),
email: text().notNull(),
},
(table) => [
uniqueIndex("users_table_email_unique").on(table.email)
]
);
