# pg-query-native [![Build Status](https://travis-ci.org/zhm/node-pg-query-native.svg?branch=master)](https://travis-ci.org/zhm/node-pg-query-native)

The real PostgreSQL parser for nodejs.

This is based on the output of [libpg_query](https://github.com/lfittl/libpg_query). This wraps the static library output and links it into a node module for use in js.

All credit for the hard problems goes to [Lukas Fittl](https://github.com/lfittl).

## Installation

```sh
npm install pg-query-native
```
