Two failures stopped a docker run from producing anything. Chrome
aborted on launch with 'chrome_crashpad_handler: --database is
required', because its crash reporter cannot start in a minimal
container, so disable the crash reporter on the container launch path.
kage never uploads Chrome crash dumps, so nothing is lost.
The image also created the kage user without a home directory, so HOME
was an unwritable /home/kage. kage writes its default output and resume
state under $HOME/data/kage and Chrome puts its profile and crash
database under HOME too, so both failed with a permission error and the
mounted /out volume captured nothing. Point HOME at the /out volume so
all of it lands somewhere writable that the mount picks up.
kage renders every page in headless Chrome, snapshots the final
DOM, strips all JavaScript, and localises CSS, images, and fonts
so a site can be browsed offline as a plain folder of files.
The engine is split into small packages:
urlx deterministic URL to local-path mapping and scope rules
sanitize remove scripts, on* handlers, and javascript: URLs
asset rewrite HTML and CSS references, download assets
browser headless Chrome pool over the DevTools protocol
robots robots.txt matcher
clone the orchestrator: a polite resumable breadth-first crawl
The cli package wires a cobra and fang command surface with two
commands, clone and serve. Every pure package has table tests; the
browser and clone packages add Chrome-driven end-to-end tests that
skip when no browser is present or under -short.
CI runs gofmt, vet, build, race tests, golangci-lint, govulncheck,
and a tidy check on Linux and macOS. A goreleaser config fans one
tag out to archives, deb/rpm/apk, a Chromium-bundled GHCR image,
and the package managers. A tago docs site builds to Pages and
Cloudflare.
