An insanely fast osm parser

The idly-faster-osm-parser is roughly 3kb's gzipped.

This parser parses on the basis of the shape of an .osm file. It tries to avoid using any kind of xml parser and treats the xml as a simple string, hence you can parse gigabytes of data.

Please note it only supports .osm files.

``bash

The idly-faster-osm-parser is roughly 3kb's gzipped. You can import it just like any npm module

Usage

`Javascript
import idlyParser from 'idly-faster-osm-parser'

const XML2 =



;

const items = idlyParser(XML2);
[
// {
// attributes: {
// changeset: '1',
// timestamp: '2009-03-07T03:26:33Z',
// uid: undefined,
// user: undefined,
// version: '1',
// visible: true,
// },
// id: 'n1',
// loc: { lon: 0, lat: 0 },
// tags: {},
// type: 'node',
// },
// ];
