Guides Databases

Use PostgreSQL

Add PostgreSQL as a database with the @primate/postgresql module. Configure it in config/database; Primate connects to it and provides a unified API.

Ensure PostgreSQL is running and accessible.

1) Install

Install the Primate PostgreSQL package.

npm install @primate/postgresql

2) Configure

Create config/database/index.ts as a default database.

import postgresql from "@primate/postgresql";

export default postgresql({
  database: "app",
  host: "localhost",
  port: 5432,
  // username: "user",
  // password: "pass",
});

3) Create a store

Stores used with PostgreSQL abstract a table. The store will use PostgreSQL automatically, being the default database.

// stores/User.ts
import store from "primate/store";
import primary from "pema/primary";
import string from "pema/string";

export default store({
  id: primary,
  name: string,
  email: string,
});

4) Use the store

Use the store in routes.

// routes/users.ts
import route from "primate/route";
import User from "#store/User";

route.get(async () => {
  const users = await User.find({});
  return users;
});

route.post(async (request) => {
  const user = await User.insert(request.body);
  return user;
});
