mix live_capture.gen.schema (live_capture v0.2.9)

Generates a JSON schema for capture modules

This is useful for automated visual regression testing with Playwright.

Usage

mix live_capture.gen.schema --module MyAppWeb.LiveCapture --url-prefix /storybook path/to/captures.json

Tip: pass multiple modules by duplicating --module switches

--url-prefix should match the scope of mounted live_capture routes

Skip path to print schema to stdout.

Output Format

captures.json
