# OpenReplay Tracker
The main package of the [OpenReplay](https://openreplay.com/) tracker.
## Documentation
For launch options and available public methods, [refer to the documentation](https://docs.openreplay.com/installation/javascript-sdk#options)
## Installation
```bash
npm i @openreplay/tracker
```
## Usage
Initialize the package from your codebase entry point and start the tracker. You must set the `projectKey` option in the constructor. Its value can can be found in your OpenReplay dashboard under [Preferences -> Projects](https://app.openreplay.com/client/projects).
```js
import Tracker from '@openreplay/tracker'
const tracker = new Tracker({
projectKey: YOUR_PROJECT_KEY,
})
tracker
.start({
userID: 'Mr.Smith',
metadata: {
version: '3.5.0',
balance: '10M',
role: 'admin',
},
})
.then((startedSession) => {
if (startedSession.success) {
console.log(startedSession)
}
})
```
Then you can use OpenReplay JavaScript API anywhere in your code.
```js
tracker.setUserID('my_user_id')
tracker.setMetadata('env', 'prod')
```
