Prego is a tiny CoffeeScript library for callback-style PostgreSQL database access, migrations, and table associations. Current version is 0.3.1, published as an early development release with no documentation and unstable interfaces. It features reversible SQL migrations executed in transactions, automatic statement preparation via the 'pg' connection pool, a Table base class with snake_case to camelCase conversion, and utility classes for parallel operations. Not recommended for production use due to its alpha state and potential breaking changes.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

prego
✓ import prego from 'prego'
✗ const prego = require('prego')
ESM named import not available; default import is used.
Table
✓ const { Table } = require('prego')
✗ import { Table } from 'prego'
CommonJS destructuring require is the correct pattern; ESM named export may not exist.
client
✓ prego.client()
✗ prego.client
client is a function that returns a pg client instance; not a property.

Shows configuring Prego, executing a simple query, and creating a migration.

const prego = require('prego'); const pg = require('pg'); // Configure database connection prego.configure({ host: 'localhost', port: 5432, database: 'test', user: process.env.DB_USER ?? 'postgres', password: process.env.DB_PASS ?? '' }); // Execute a query prego.execute('SELECT NOW()', (err, res) => { if (err) throw err; console.log(res.rows[0]); }); // Use a migration prego.migration.create('add_users', 'up', (sql) => { sql(`CREATE TABLE users (id SERIAL PRIMARY KEY, name TEXT)`); });
