No data? No problem!

Automatically seed your database with production-like dummy data based on your schema for local development and testing.

Automated values

Seed automatically determines the values in your database so you don’t have to define each and every value unless you want to be specific, in which case you just use Typescript to define those values. Our default data automatically adds necessary built-ins, like country lists, currency codes etc.

Automated relationships

Seed automatically creates relational entities so you don’t have to keep track of IDs in one table when you’re defining values in another.

Type-safe by default

await seed.posts([{
  title: "Why you need Seed",
  author: {
    email: "[e-mail]",
  },
  comments: (x) => x(3),
}]);

Seed creates a TypeScript client based off your database structure. Values are safe, and soft documented. You have the full power of the typescript language and the rich node.js infrastructure when seeding production-like data and defining data values.

Deterministic data

Seed uses Copycat for its data generation functions, and all data generation is fully deterministic. That means if you use the same inputs, you'll always get the same data outputs. That makes seed great for consistent tests and development.
