Simple wrapper for [lighthouse-ci](https://github.com/GoogleChrome/lighthouse-ci).

## Usage

There are two wrapper scripts around the lhci command you could use:

- `/usr/bin/lhci-official`: This will simply forward your command to the official binary at `/usr/local/bin/lhci`
- `/usr/bin/lhci`: This is a modified wrapper to post-process the created report file to prepare an upload.

The wrapper `/usr/bin/lhci` will do the following:

- create `DIST=$LHCI_BASE_DIR/$UPLOAD_OUTPUT_DIR/dist/`
- find all files flagged with `isRepresentativeRun` in the `manifest.json`
- copy those files to `$DIST`

To get it working you need to configure the `fileupload` in `.lighthouserc.yml`command line configuration will not work:

```Yaml
---
ci:
  [...]
  upload:
    target: filesystem
    # has to be a relative path to the .lighthouserc.yml location
    outputDir: lhci_reports
```

What you will get is the following file structure which could be used as an upload source:

```Shell
lhci_reports/dist/
├── 9cf658e2-202007160745.html
├── f33fa4c4-202007160745.html
└── ffae8d3e-202007160745.html

# <FILENAME_HASH>-<DATETIME>.html
```

You will also get the target URLs in your CI output:

```Shell
/usr/bin/lhci autorun

[...]

All results processed!
