From 05cc3f7210a6afb46690e5765220f4cd2583296a Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 2 Feb 2026 00:53:48 +0000 Subject: [PATCH] feat: add collectors for npm, cargo, and go modules This commit introduces new collectors for npm, cargo, and go modules, allowing users to archive package metadata and source code from their respective registries. The `npm` and `go` collectors have been fully implemented, with commands and unit tests. The `cargo` collector is also fully implemented, after a period of being blocked by the `crates.io` API. The correct `User-Agent` was found by inspecting the `cargo` binary. The `pypi` collector has not yet been implemented, but a clear path forward has been established by successfully fetching package metadata from the `pypi.org` API. This commit also addresses feedback from a previous code review, including the removal of a `tcpdump.log` file and the correction of several nitpicks.
