Ballista

A minimal JS module and small CLI utility for running concurrent Lighthouse tests. Run multiple iterations across multiple URLs to reduce the friction of performance benchmarking.

Prerequisites (local development)

• Node.js version 16.16.0 or higher
• Google Chrome browser version 59 or higher

Installation

To install Ballista as a global cli tool, run the following command

npm install -g @deogle/ballista

Or to add the package as a dependency

npm install -S @deogle/ballista

As an alternative to locally installing, the most recent version of the tool can be run directly from npm with npx

npx @deogle/ballista@latest <etc>

Usage

The basic usage of the CLI tool follows the form

ballista -i 5 -c --url <baseline-url> <target-urls>

Where

• baseline-url the url being benchmarked against.
• target-urls a space delimited list of urls to run test against the benchmark
• -c run in comparison mode
• -i sets the number of iterations to run (the more iterations, the more accurate the results but the longer the total runtime).
