Potygen CLI (Postgres typescript generator)

Command line tool for generating types for potygen

Installation

yarn add --dev @ovotech/potygen-cli

Usage

If we had sql string templates like this:

examples/simple.ts

import { sql } from '@ovotech/potygen';
import { Client } from 'pg';

const db = new Client(process.env.POSTGRES_CONNECTION);

async function main() {
  await db.connect();
  const productsSql = sql`SELECT product FROM orders WHERE region = $region`;
  const data = await productsSql(db, { region: 'Sofia' });

  console.log(data);

  await db.end();
}

main();

We could then run the potygen cli tool to generate types for them

yarn potygen -n postgres://localhost:5432/postgres examples/simple.ts

After that you can import the types and use them, which will type both parameters of the query as well as the results

examples/simple-typed.ts

import { sql } from '@ovotech/potygen';
import { Client } from 'pg';
import { ProductsSqlQuery } from './simple-typed.queries';

const db = new Client(process.env.POSTGRES_CONNECTION);

async function main() {
  await db.connect();
  const productsSql = sql<ProductsSqlQuery>`SELECT product FROM orders WHERE region = $region`;
  const data = await productsSql(db, { region: 'Sofia' });

  console.log(data);

  await db.end();
}

main();
