📝 Walkthrough

Walkthrough

The repository migrated dependency installation and development commands from npm to pnpm 11. Workspaces, mise, CI workflows, release scripts, Dependabot, documentation, and lockfile handling were updated.

Changes

pnpm Workspace Migration

Layer / File(s) Summary
Workspace and toolchain foundation
mise.toml, pnpm-workspace.yaml, package.json, e2e/*/package.json, .gitignore, .prettierignore, CHANGELOG.md, src/response/web-records.ts
The repository defines pnpm 11, workspace membership, supported platforms, dependencies, ignored files, and package metadata.
CI and Dependabot automation
.github/dependabot.yml, .github/workflows/*, e2e/*/vitest.config.*
CI installs pnpm through mise and uses frozen-lockfile commands for linting, testing, building, documentation, and publishing. Dependabot targets the root workspace lockfile. End-to-end tests use workspace-linked packages and expanded Vitest patterns.
Developer and release command updates
.precious.toml, CLAUDE.md, README.dev.md, dev-bin/release.sh
Local tooling, release scripts, and development instructions use pnpm. Release publishing retains npm provenance publishing.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to f8fca

The PR switches dependency management to pnpm and makes the required dependency declarations explicit; the reported tests, linting, packaging, and CI checks pass, so no actionable merge-blocking risk remains.

Suggested reviewers: horgh, oschwald

Poem

A rabbit checks the workspace map,
Then runs pnpm along the path.
Mise installs the pinned tool,
Frozen locks keep builds in rule.
npm publishes provenance.

Review comments addressed

All five are valid. Three needed code changes, pushed in 1785fa7; two were already fixed in a19fb06.

zizmor cache-poisoning, release.yml:26 and :69 (github-advanced-security) — fixed in a19fb06. jdx/mise-action caches by default, so adding it here reintroduced exactly the finding that the existing package-manager-cache: false settings on both setup-node steps were there to prevent. I had read those as boilerplate to carry forward rather than as a marker for this specific audit. Both mise-action steps in release.yml now set cache: false, with a comment recording why; caching stays on in test.yml and lint.yml, which zizmor does not flag. Alerts 24 and 25 no longer appear on the PR ref, and the zizmor check passes.

test.yml node check (CodeRabbit) — valid and the best of the five. The step was described as a guard but only printed, so a node shadowed by mise would still have passed it, leaving detection to whoever read the log. It now asserts, taking the matrix value through env rather than interpolating ${{ ... }} into the shell, so it does not trip the template-injection audit.

mise.toml windows-arm64 (CodeRabbit) — valid as a documentation gap; pnpm does ship pnpm-win32-arm64.zip, so unlike macos-x64 the absence was not self-evident. Resolved as "document the exclusion": MaxMind supports neither Windows ARM64 nor Intel Mac. The macos-x64 note is kept separately, because that platform would have to be excluded even if Intel Mac were supported — mise silently resolves it to an archive containing no pnpm.

CLAUDE.md MD022 (CodeRabbit) — fixed, though it is pre-existing rather than introduced here; the heading sits against its list on main too. Worth noting markdownlint is not configured in this repo, so the change is for consistency with the file's other headings rather than to satisfy a check.

One thing that cannot be verified before merge

Alert 23 (zizmor/adhoc-packages, open since 2026-06-29) points at release.yml:48 on main — the npm install -g npm@latest line this PR deletes. Code-scanning alert state tracks the default branch, so #23 stays open until this merges, however green the PR is. What is demonstrated now: the line is gone, the zizmor check passes on the PR ref, and a local zizmor 1.29.0 run reports no findings across all workflows. If the acceptance criterion is worded as "alert resolved", that lands at merge, not here.

@mm-jpoole
mm-jpoole requested a review from dhogan8 August 27, 2026 20:51
Manage dependencies with pnpm 11 instead of npm, pinned in
mise.toml. packageManager field omitted because it makes
pnpm write a two-document pnpm-lock.yaml that Dependabot cannot parse.

The e2e projects are now pnpm workspace members, replacing the
`npm link` sequence which has no pnpm equivalent as of version 11.
pnpm-lock.yaml replaces three package-lock.json files.

CI installs only pnpm from mise and puts it on PATH. A full mise install
would also install mise's own node, which could silently test the wrong
version. test.yml now asserts the major version so a shadowed node fails
the job.

All three workflows set `cache: false` on mise-action:

- zizmor's cache-poisoning audit flags a restorable cache
in a job that publishes artifacts built at runtime.
- In test.yml and lint.yml it skips a restore that can
never hit due to `install: false`

Publishing stays on npm: adopting pnpm 11's own OIDC support is a
separate follow-up (SCO-9226). The publish job moves to node 24,
allowing us to drop `npm install -g npm@latest`, resolving the
one open zizmor finding on this repo (adhoc-packages);

lint.yml drops:

- `jq empty package-lock.json` step. `--frozen-lockfile` already
fails on a bad lockfile.
- `Test compile` (`tsc --noEmit`). The lint script already runs it
twice.

pnpm 11 reads non-auth settings from the workspace file so `engineStrict`
moves from `.npmrc` to `pnpm-workspace.yaml`.

In the e2e manifests, vitest and typescript move to devDependencies. The
root lint script drops its unnecessary `pnpm exec` prefixes (they are on
the PATH).

dependabot.yml narrows from directories: ["/", "**/*"] to directory: /.
One root pnpm-lock.yaml covers the workspace, and a per-directory run
under e2e/* would bump a manifest and leave the root lockfile stale. The
glob used to match e2e/js and e2e/ts, so dropping it also discards their
kind 2/3 failures in dependabot-failure-watcher.yml.

Two dependency changes:
- `maxmind` becomes a direct dependency because type checking failed
with package managers that do not flatten node_modules (e.g. pnpm).
-The `deploy:docs` script and its `gh-pages` devDependency are deleted.
Nothing called it. release.yml deploys docs with
peaceiris/actions-gh-pages

mise.toml sets lockfile_platforms to exclude windows-arm64 and
macos-x64, neither of which we support. macos-x64 also cannot work
at all, since pnpm 11.0.5+ ship no darwin-x64 binary.

README.dev.md and CLAUDE.md:

- instruct to run `mise install` before `pnpm install` to prevent using
whichever pnpm is on PATH.
- README.dev.md gains the supported-platform list to go with with the
lockfile_platforms setting above.

The reformatting in src/response/web-records.ts comes from prettier
3.9.6, which the fresh install pulled in place of 3.8.4. It is the only
src/ change on this branch.

Config and comments are kept consistent with the parallel
GeoIP2-node conversion when possible.
