\n\n### NOTE for existing users\n\n> **VERSION 3.0** Is a significant rewrite from earlier versions.\n Existing 2.x users should be sure to read the [Upgrade Guide](docs/upgrading-from-v2.md).\n\n
\n\n# Installation\n\nIn a browser:\n\n```html\n \n```\n\n> after downloading the [source](dist/state-machine.js) or the [minified version](dist/state-machine.min.js)\n\nUsing npm:\n\n```shell\n npm install --save-dev javascript-state-machine\n```\n\nIn Node.js:\n\n```javascript\n var StateMachine = require('javascript-state-machine');\n```\n\n# Usage\n\nA state machine can be constructed using:\n\n```javascript\n var fsm = new StateMachine({\n init: 'solid',\n transitions: [\n { name: 'melt', from: 'solid', to: 'liquid' },\n { name: 'freeze', from: 'liquid', to: 'solid' },\n { name: 'vaporize', from: 'liquid', to: 'gas' },\n { name: 'condense', from: 'gas', to: 'liquid' }\n ],\n methods: {\n onMelt: function() { console.log('I melted') },\n onFreeze: function() { console.log('I froze') },\n onVaporize: function() { console.log('I vaporized') },\n onCondense: function() { console.log('I condensed') }\n }\n });\n```\n\n... which creates an object with a current state property:\n\n * `fsm.state`\n\n... methods to transition to a different state:\n\n * `fsm.melt()`\n * `fsm.freeze()`\n * `fsm.vaporize()`\n * `fsm.condense()`\n\n... observer methods called automatically during the lifecycle of a transition:\n\n * `onMelt()`\n * `onFreeze()`\n * `onVaporize()`\n * `onCondense()`\n\n... along with the following helper methods:\n\n * `fsm.is(s)` - return true if state `s` is the current state\n * `fsm.can(t)` - return true if transition `t` can occur from the current state\n * `fsm.cannot(t)` - return true if transition `t` cannot occur from the current state\n * `fsm.transitions()` - return list of transitions that are allowed from the current state\n * `fsm.allTransitions()` - return list of all possible transitions\n * `fsm.allStates()` - return list of all possible states\n\n# Terminology\n\nA state machine consists of a set of [**States**](docs/states-and-transitions.md)\n\n * solid\n * liquid\n * gas\n\nA state machine changes state by using [**Transitions**](docs/states-and-transitions.md)\n\n * melt\n * freeze\n * vaporize\n * condense\n\nA state machine can perform actions during a transition by observing [**Lifecycle Events**](docs/lifecycle-events.md)\n\n * onBeforeMelt\n * onAfterMelt\n * onLeaveSolid\n * onEnterLiquid\n * ...\n\nA state machine can also have arbitrary [**Data and Methods**](docs/data-and-methods.md).\n\nMultiple instances of a state machine can be created using a [**State Machine Factory**](docs/state-machine-factory.md).\n\n# Documentation\n\nRead more about\n\n * [States and Transitions](docs/states-and-transitions.md)\n * [Data and Methods](docs/data-and-methods.md)\n * [Lifecycle Events](docs/lifecycle-events.md)\n * [Asynchronous Transitions](docs/async-transitions.md)\n * [Initialization](docs/initialization.md)\n * [Error Handling](docs/error-handling.md)\n * [State History](docs/state-history.md)\n *
