## Overview of garie-lighthouse
Garie-lighthouse was developed as a plugin for the [Garie](https://github.com/boyney123/garie) Architecture.
[Garie](https://github.com/boyney123/garie) is an out the box web performance toolkit, and `garie-lighthouse` is a plugin that generates and stores lighthouse data into `InfluxDB`.
`Garie-lighthouse` can also be run outside the `Garie` environment and run as standalone.
If your interested in an out the box solution that supports multiple performance tools like `lighthouse`, `google-speed-insight` and `web-page-test` then checkout [Garie](https://github.com/boyney123/garie).
If you want to run `garie-lighthouse` standalone you can find out how below.
## Getting Started
### Prerequisites
- Docker installed
### Running garie-lighthouse
You can get setup with the basics in a few minutes.
First clone the repo.
```sh
git clone git@github.com:boyney123/garie-lighthouse.git
```
Next setup you're config. Edit the `config.json` and add websites to the list.
```javascript
{
"cron": "00 00 */6 * * *",
"urls": [
{
"url": "https://www.comparethemarket.com",
"report": true
},
{
"url": "https://www.bbc.co.uk",
"report": true
},
{
"url": "https://www.cnn.com",
"report": true
}
]
}
```
Once you finished edited your config, lets build our docker image and setup our environment.
```sh
docker build -t garie-lighthouse . && docker-compose up
```
This will build your copy of `garie-lighthouse` and run the application.
On start garie-lighthouse will start to gather performance metrics for the websites added to the `config.json`.
## Data collected
Lighthouse comes with loads of audits out the box. You can view all metrics in the reports.
Garie-lighthouse filters what data is stored into influxDB and returned in the webhook.

## Viewing reports
