# mus.js
A simple mouse tracking library to provide insights on how your users are handling your layout / user experience.
This library was created so you don't need an external service to "record" your users mouse events and "play" them in a later moment.
**mus** works with any AMD you wish and its setup is extremely simple - **5.6kb**
## Recording
```js
// Instantiate a mus object
var mus = new Mus();
// Start recording
mus.record();
// After a while, stops
setTimeout(function() {
mus.stop();
}, 5000);
```
## Playing
```js
// Sets playback speed (optional, default NORMAL)
mus.setPlaybackSpeed(mus.speed.SLOW);
// Starts playing and enjoy
mus.play();
```
## Example
<img height="300" src="https://i.imgur.com/GCYD9EP.gif"/>
## Public methods
### Controls
#### record()
Starts a recording session for current screen. If there is already a session recorded, it appends to it.
#### stop()
Stops a recording or a playback.
#### play(onfinish)
Plays current recording session.
#### pause()
Pauses current playback.
#### release()
Releases all data recorded or set.
### Getters and setters
#### getData()
Returns all data collected during recording.
#### setData(data)
Sets custom data for playback. It must be a JSON object collected from `getData`.
#### setFrames(frames)
Same as `setData`, but allows only to set the `frames` array.
#### setWindowSize(width, height)
During recording, all data collected contains window dimensions as well, so if your recorded data comes from a different window dimension, **mus** automatically adapts to current window size. This function allows you to set a custom playback window size if you decide to use `setFrames` instead of `setData` (that already sets windows dimensions).
#### setPlaybackSpeed(speed)
Allows playback to be faster or slower.
Default constants: `mus.speed.SLOW` (35), `mus.speed.NORMAL` (15), `mus.speed.FAST` (5)
You may decide to use custom values as you wish.
#### setTimePoint(bool)
Records time elapsed for each point for a precise data recording.
Default: disabled
#### isRecording()
Informs if **mus** is currently recording something.
#### isPlaying()
Informs if **mus** is currently playing something.
#### isTimePoint()
Informs if **mus** is recording time for each data point.
# Roadmap
- Detect touch movements and clicks;
- Get form inputs;
- Allows real clicks during setup (default false);
- Suggestions are greatly appreciated!
# Version history
## v1.1.0
- Added time point recording for precise data;
## v1.0.1
- Added minified file for distribution;
