iD - friendly JavaScript editor for OpenStreetMap

Basics

iD is a JavaScript OpenStreetMap editor.
It's intentionally simple. It lets you do the most basic tasks while not breaking other people's data.
It supports all popular modern desktop browsers: Chrome, Firefox, Safari, Opera, Edge, and IE11.
iD is not yet designed for mobile browsers, but this is something we hope to add!
Data is rendered with d3.js.

Prerequisites

Node.js version 4 or newer
git for your platform
- Note for Windows users:
  - Edit $HOME\.gitconfig:
    Add these lines to avoid checking in files with CRLF newlines
```
[core]
autocrlf = input
```

Installation

Note: Windows users should run these steps in a shell started with "Run as administrator". This is only necessary the first time so that the build process can create symbolic links.

To run the current development version of iD on your own computer:

Create a local git clone of the project, then cd into the project folder
Run npm install (this will run the prepublish script that builds everything)
Run npm start
Open http://localhost:8080/ in a web browser

For guidance on building a packaged version, running tests, and contributing to development, see CONTRIBUTING.md.
