Generating Database Types

Learn how to generate your Supabase Database types using the typegen command

When you change your Database schema, you need to also remember to update the Typescript types that the Supabase Client can use to strong-type your queries and mutations.

Following a change in the schema, you need to do two things:

  1. Reset the Database: if you have changed the schema manually, e.g. updating the SQL code, you need to either reset or restart your Supabase instance. You can do so using the command npm run supabase:db:reset
  2. Generate the new type definitions: now, you can run the command npm run typegen to generate the types. The generated file will be available at src/database.types.ts

That's it! Always remember to update your schema types after changing your database schema.
