Overview

Per-project config: an optional portless.json (or portless.yml) plus inferred defaults. Mirrors portless's config.ts/auto.ts: name is inferred from the config, the git root, or the directory; tld defaults to "localhost".

Instance Method Details

#hostname(name = nil, worktree: true) ⇒ Object

The full hostname an app registers (e.g. "shirabe.org.localhost" when tld is set to that, or ".localhost" by default). name overrides the base (used by --name); worktree: prepends the git-worktree branch prefix so a linked worktree gets its own URL (auth.<name>.localhost).

def hostname(name = nil, worktree: true)
  base = name ? sanitize_label(name) : @name
  host = tld.split(".").include?(base) ? tld : "#{base}.#{tld}"
  prefix = worktree ? worktree_prefix : nil
  prefix ? "#{prefix}.#{host}" : host
end

#tld_warning ⇒ Object

A warning string if the tld looks risky, else nil. (.localhost / .test are safe.)

def tld_warning
  last = tld.split(".").last
  return unless RISKY_TLDS.include?(last)

  "tld \".#{last}\" is a real/reserved TLD — prefer \".localhost\" so you don't intercept real traffic"
end

#worktree_prefix ⇒ Object

The git-worktree subdomain prefix for this project dir (nil if none). Memoized — it shells out to git.
