pg-plus

This library wraps the node-postgres library to provide some nice things:

• promise support
• mongoDB-like interface
• case changing (i.e., can be set to automatically convert column names like my_column to JavaScript names like myColumn)
• automatic resource clear up (uses Bluebird's disposer method behind the scenes)

Install

$ npm install pg-plus

Examples

This is a rough and ready demonstration until I have time to write more full documentation. Please also check out the test.js for examples.

// require the lib
// (I use ES6, hence the extra .default part)
var PostgresPlus = require('pg-plus').default;

// set it up with some connection string (e.g. postgres://postgres@localhost/test)
var pg = new PostgresPlus(myConnectionString);

// get a table (default primary key is 'id')
var table1 = pg.table('table1');

// get a table using '_id' as the primary key
var table2 = pg.table('table2', '_id');

// get a table using '_id' as the primary key, and converting column names
// from snake case
var table3 = pg.table('table3', {id: '_id', case: 'snake'});

// get some rows
// refer to MongoDB docs for query syntax, most basic stuff should work
test.find({column: 'value', number: {$lt: 1}}).then(function (rows) {
  console.log(rows);
});

// get a single row
test.findOne({id: 5}).then(function (row) {
  console.log(row);
});

// since we were using the primary key, there is a shorthand for the above
test.findOne(5).then(function (row) {
  console.log(row);
});
