Seed supports multiple databases and ORMs through adapters.

ORMs

Prisma

Note Currently supported providers: postgres, mysql, sqlite

@snaplet/seed supports Prisma (opens in a new tab) using the @snaplet/seed/adapter-prisma:

import { SeedPrisma } from "@snaplet/seed/adapter-prisma";
import { defineConfig } from "@snaplet/seed/config";
import { PrismaClient } from "@prisma/client";
export default defineConfig({
  adapter: () => {
    const client = new PrismaClient();
    return new SeedPrisma(client);
  },
  select: [
    "!*_prisma_migrations",
  ],
});

PostgreSQL

Postgres.js

@snaplet/seed supports Postgres.js (opens in a new tab) using the @snaplet/seed/adapter-postgres adapter:

seed.config.ts


import { SeedPostgres } from "@snaplet/seed/adapter-postgres";
import { defineConfig } from "@snaplet/seed/config";
import postgres from "postgres";
export default defineConfig({
  adapter: () => {
    const client = postgres(process.env.DATABASE_URL);
    return new SeedPostgres(client);
  },
});

node-postgres

@snaplet/seed supports node-postgres (opens in a new tab) using the @snaplet/seed/adapter-pg adapter:

seed.config.ts


import { SeedPg } from "@snaplet/seed/adapter-pg";
import { defineConfig } from "@snaplet/seed/config";
import { Client } from "pg";
export default defineConfig({
  alias: {
    inflection: true,
  },
  adapter: async () => {
    const client = new Client({ connectionString: process.env.DATABASE_URL  });
    await client.connect();
    return new SeedPg(client);
  },
});

SQLite

better-sqlite3

@snaplet/seed supports better-sqlite3 (opens in a new tab) using the @snaplet/seed/adapter-better-sqlite3 adapter:

seed.config.ts


import { SeedBetterSqlite3 } from "@snaplet/seed/adapter-better-sqlite3";
import { defineConfig } from "@snaplet/seed/config";
import Database from "better-sqlite3";
export default defineConfig({
  adapter: () => {
    const client = new Database('sqlite.db');
    return new SeedBetterSqlite3(client);
  },
});

export default defineConfig({
  adapter: async () => {
    const client = await createConnection(process.env.DATABASE_URL);
    await client.connect();
    return new SeedMysql2(client);
  },
