Configuration

The yomi flags grouped by concern, their defaults, and the CHROME_BIN environment variable the render path honors.

yomi is configured through command-line flags (see the CLI reference). This page groups them by the job they do and covers the one environment variable yomi reads.

Fetching and render

How yomi gets the page, and when it launches a browser.

Flag Default Meaning
--render auto auto = static fetch first, render only when the page looks JavaScript-gated; on = always render; off = never launch a browser
--scroll false Auto-scroll in render mode for lazy-loaded content
--timeout 30s Per-request timeout
--user-agent User-Agent for fetches
--chrome Path to the Chrome/Chromium binary
--control-url Attach to a running Chrome DevTools endpoint

In auto mode yomi decides a page is JavaScript-gated when the static HTML has an empty single-page-app mount (#root, #__next, #app), a <noscript> saying JavaScript is required, or under 25 words of visible text. Only then does it escalate to the browser.

Extraction and output

What the Markdown looks like.

Flag Default Meaning
--links inline inline or reference link style
--no-front-matter false Omit the YAML front-matter header
--title-heading false Keep the title as an H1 at the top of the body
--wrap 0 Hard-wrap prose at column N (0 = no wrap)
-o, --out varies Output file (read), or folder/file (site); defaults to the host name for a site
-q, --quiet false Suppress progress output

Images

Flag Default Meaning
--images remote remote, download, or inline
--max-image-mb 16 Skip images larger than this

See the images guide for where downloaded and inlined files land.

Crawl and scope

These apply to yomi site.

Flag Default Meaning
-s, --single false One combined file instead of a folder
-p, --max-pages 0 Stop after N pages (0 = unlimited)
-d, --max-depth 0 Depth cap (0 = unlimited)
--workers 4 Concurrent page workers
--subdomains false Treat subdomains of the seed as in scope
--scope-prefix Only crawl pages whose path starts with this prefix
--exclude Path prefixes to skip (repeatable)
--no-robots false Ignore robots.txt

Environment variables

yomi reads one environment variable, for locating the browser on the render path.

Variable Meaning
CHROME_BIN Path to the Chrome/Chromium binary. Equivalent to --chrome.

The render path needs a Chrome or Chromium binary on the host. yomi looks for a system install automatically (Google Chrome on macOS and Windows, google-chrome/chromium on Linux); CHROME_BIN or --chrome points it at a specific one. The Docker image (ghcr.io/tamnd/yomi) bundles Chromium and sets CHROME_BIN for you. In --render auto many pages are served as real HTML and never touch the browser, so for a lot of reads no browser is needed at all; --render off guarantees it.
