lhci

Custom image for lighthouse-ci

Custom wrapper Docker image for 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.ymlcommand line configuration will not work:

---
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:

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:

/usr/bin/lhci autorun

[...]
