    Just a silly little db management and query builder for Postgresql.

    Usage

    const Db = require('piggybag');
    
    const db = new Db();
    
    const updatedUser = await db.transaction(async () => {
    
        await db
            .from('users')
            .where({ id: 12 })
            .update({ username: 'myusername' });
        
        return await db
            .from('users')
            .select('id,username')
            .where({
                 $or: {
                     id: 12,
                     username: 'myusername'
                 }
             })
             .first();
    
    });
    

    In the above example we wrap our operations in a transaction, which automatically triggers connection to the Postgresql server if not present. The transaction is automatically commited if no error occurs, and automatically rolled back if an error does occur.

    Transactions can be inside transactions - the library will figure out when to commit or roll back.
