Lighthouse Report Generator

Overview

Lighthouse's report generator is the entry point for creating reports from an LHR (Lighthouse Result object). It returns results as HTML, JSON, and CSV.

It runs natively in Node.js but can run in the browser after a compile step is applied during our bundling pipeline. That compile step uses inline-fs, which takes any fs.readFileSync() calls and replaces them with the stringified file content.

Because it's shared between core and the report, dependencies (both code and types) should be kept minimal.
