# pm4js-core

### Process Mining for Javascript - Core Package
PM4Js is a library for process mining in Javascript. The execution is supported in modern browsers (Chrome, ...) and Node.JS

### Install
#### Browser
Include the script **dist/pm4js_latest.js** in your web page to use the functionalities of PM4Js.

#### Node (package)
Install pm4js by doing **npm install -g pm4js**. Then, PM4Js can be used in Node by doing:
**require('pm4js')**.


#### Node (local installation)
Clone the Git project, and install the required packages by doing **npm install**. Then, PM4Js can be used in Node by doing:
**require('./init.js')**.

### Documentation
Extensive documentation is available [here](./DOCS.md).
Some examples are included in the **examples/html** folder (HTML pages) and **examples/node** folder (Node.JS examples).
