-
SIGNAL =
Regex.union(/require\(['"]express['"]\)/, /from ['"]express['"]/, /app\.use\(express\.json\(\)\)/, /app\.use\(express\.urlencoded\(\{ extended: true \}\)\)/) -
Single precompiled alternation — one PCRE2 scan over the file instead of up to four separate
.matchpasses. Regex.union wraps each branch verbatim, so the boolean result is identical.

Instance Method Detail
Cheap filename-only filter the detector pass uses to skip
#detect on files the detector cannot possibly match. The
default true preserves prior behavior (every detector runs on
every file). Override with the same predicate the body of
#detect starts with — e.g., filename.ends_with?(".py") for a
Python framework detector — so the detector loop avoids the
#detect dispatch on files outside the detector's language.
On large codebases (saleor's 4255 .py files) this lifts ~100
virtual #detect calls per file out of the hot loop because
most detectors' inner first-line is exactly this kind of cheap
filename check.
