How to

Use --sites flag

$ lighthouse-mariner -s http://www.google.com

Multiple sites:

$ lighthouse-mariner -s http://www.google.com,http://www.yahoo.com

Use --file usage

Create a text file containing each URL you would like to audit (1 per line). This example can be found in the examples/ folder of the repo.

url-list.txt:

https://www.google.com
https://www.yahoo.com
https://www.msn.com
https://www.bing.com

To run audit on files:

$ lighthouse-mariner -f ./url-list.txt

Output

Console

If the -q flag is not used, the console will show the progress of each scan as it completes.

The console will also display a table of the results when completed.

Folder

A folder is generated in your working directory (if it doesn't already exist), named lighthouse-mariner-reports/. All output files will be created here.

Use the -o flag and specify a directory to change the output directory.

JSON

As the script runs lighthouse on each URL, it will add the latest scan info to a audit-{TIMESTAMP}.report.json file. (If the script ends prematurely for any reason, the latest data will be available in this file.)

HTML

When the script completes, it will create an HTML report: audit-{TIMESTAMP}.report.html.

Example

Compare Tool

The compare tool can be used to monitor progress of routes over time. This tool will accumulate all scan data from a directory, group it by each route, and generate an output HTML file that will display the differences of the scans over time via graphs and tables.

Usage

$ lighthouse-mariner compare --help
Usage: cmd compare [options]

compare sites scans over time to monitor progress

Options:
  -f, --folder <path>  name of a absolute path, relative path, or name of a directory within /lighthouse-mariner-reports folder
  -V, --version        output the version number
  -h, --help           display help for command
