Ports the nix / direnv / dependabot setup from moq-dev/moq so this repo's tooling and dependencies stop drifting on their own.

What landed

File From Notes
.envrc copied verbatim nix-direnv 3.1.0 + the weekly background GC
.github/workflows/update-flake.yml copied verbatim same pinned action SHAs
flake.nix adapted see below
flake.lock adapted nixpkgs / flake-utils / systems nodes lifted from moq's lock, same revs and hashes, so both repos track one nixpkgs
.github/dependabot.yml adapted bun + github-actions only

flake.nix is written fresh rather than copied: moq's is 21 KB of Rust, Python, Swift, Kotlin, Go, Dart, OBS, and IETF draft tooling, none of which exists here. This repo's shell is bun, nodejs_24, and just, which is everything the justfile actually invokes.

.github/dependabot.yml drops the cargo and uv ecosystems and their crate-specific ignore rules for the same reason. The weekly cadence, the 7-day cooldown, and the group-everything pattern carry over unchanged. Nix has no Dependabot ecosystem, which is what update-flake.yml is for; that's noted in both files so the gap doesn't read as an oversight.

The bun version had already drifted

The pinned nixpkgs ships bun 1.3.13; this repo pinned 1.3.4 in packageManager and in pr.yml. So the dev shell would have disagreed with CI from the first commit, and it isn't harmless: a bare bun i on a newer bun rewrites bun.lock (it adds a configVersion key), which is exactly the kind of unrelated diff noise this setup is supposed to prevent. Every just recipe here starts with a bare bun i.

So packageManager and pr.yml move to 1.3.13 to match the shell. That makes three pins that have to agree, and the set is documented as such in CLAUDE.md, in a comment on the flake.nix bun entry, and in a comment above setup-bun in pr.yml: when the monthly update-flake.yml PR moves nixpkgs, the other two move with it.

CLAUDE.md also had bun v1.3.4 written into its Technology Stack list, now updated. README.md gains nix develop / direnv allow as the setup path, keeping the manual bun i route for people without Nix.

Verification

Run locally on the branch, all passing: bun install --frozen-lockfile, bun run check, bun test, bun astro build --mode live, bun scripts/check-og.ts. The three YAML files parse.

Two things I could not verify, both worth a reviewer's eye:

  • flake.nix does not evaluate here. This container has no nix, so the file is unvalidated beyond a read-through and a delimiter check. It wants a nix flake check (or just a nix develop) before merge. nixfmt-tree as formatter and flake-utils.lib.eachSystem follow moq's usage against this same nixpkgs rev.
  • bun 1.3.13 specifically is untested. This container has 1.3.11, not 1.3.13. What I did confirm on 1.3.11 is the part that could have broken CI: bun install --frozen-lockfile against the 1.3.4-written bun.lock passes and leaves the lock untouched, so bun.lock is deliberately not regenerated in this PR. CI on this PR is the real check of the bumped pin.

Deliberately not done

pr.yml still installs bun via setup-bun rather than entering the nix shell the way moq's check.yml does. That's a larger change to the one workflow that currently gates merges, it would slow the check by the nix install, and I can't test it here. Worth doing as a follow-up if you want nix to be the single source of truth in CI too; say the word and I'll open it.

Ports the setup from moq-dev/moq so this repo's tooling and dependencies
stop drifting on their own.

- flake.nix / flake.lock pin bun, node, and just. nixpkgs and flake-utils
  are locked to the same revisions moq uses, so the two repos share a
  toolchain rather than each tracking their own.
- .envrc loads that shell through direnv, verbatim from moq.
- .github/dependabot.yml groups weekly bun and github-actions updates
  behind a 7 day cooldown, so a compromised release has time to be yanked
  before it lands. The cargo and uv ecosystems don't apply here.
- .github/workflows/update-flake.yml opens a monthly flake.lock PR, since
  Dependabot has no nix ecosystem.

The pinned nixpkgs ships bun 1.3.13 while the repo pinned 1.3.4, so the
dev shell would have disagreed with CI from the first commit: a bare
`bun i` on the newer bun rewrites bun.lock. packageManager and pr.yml
move to 1.3.13 to match, and the three pins are documented as a set that
moves together when update-flake.yml bumps nixpkgs.

P2 Badge Include Intel macOS in the flake systems

On an Intel Mac, both the newly documented nix develop setup and .envrc's use_flake fail because the flake publishes no devShells.x86_64-darwin.default. The manually enumerated systems include Apple Silicon macOS but omit the other standard Darwin architecture, even though the selected Bun, Node, and just packages support it; add x86_64-darwin so the advertised setup works there.

P2 Badge Keep the Docker Bun pin in sync

When this repository is built through its existing Dockerfile, dependency installation and the application build still run on oven/bun:1.3.4-slim, while this change declares 1.3.13 as the lockfile-writing toolchain. That leaves a fourth Bun pin outside the documented three-way synchronization and can make Docker builds behave differently from CI and nix develop, especially after the lockfile is regenerated by 1.3.13; update the Docker base alongside this pin.

Useful? React with 👍 / 👎.

Review Change Stack

Walkthrough

The repository adds a Nix flake with pinned development tools and formatter support. Direnv loads the development shell and runs weekly Nix garbage collection. Dependabot and a GitHub Actions workflow automate dependency and flake lock updates. Bun is updated to version 1.3.13 across package metadata and CI. Setup documentation describes Nix, direnv, and non-Nix installation options.

Merge Risk: 🟡 Moderate · up to b0338

Automated flake updates may fail or produce unvalidated, toolchain-divergent pull requests, and the manual development setup is incomplete. These issues should be resolved before merge.

workflow’s Nix installation step with a supported pinned installer action,
preferably DeterminateSystems/determinate-nix-action if Determinate Nix remains
acceptable. Preserve the existing update workflow behavior and pin the action to
a specific release.
- Around line 3-5: Restrict the workflow’s default job permissions to read-only,
and grant write access only to the update-flake-lock action or job that requires
it. Ensure nix-installer-action cannot use a write-capable github.token, while
preserving the updater’s ability to modify contents and pull requests.
- Line 27: Update the update-flake-lock workflow configuration to use a
least-privilege PAT or GitHub App token instead of the default github.token,
ensuring generated flake.lock pull requests trigger the existing pull_request CI
workflow. Keep the token scoped only to the permissions required for creating
the update PR.
- Around line 27-32: Keep the Bun version synchronized across pkgs.bun in
flake.lock, package.json, and the Bun pin in the pr workflow. Add a checked-in
assertion or validation that compares all three values and fails when they
differ, or update the explicit package.json and pr.yml pins whenever nixpkgs
changes pkgs.bun.

In `@README.md`:
- Around line 36-37: Update the non-Nix setup instructions in README.md to

💡 Result:

When using the Determinate Nix Installer Action, the github-token input defaults to ${{ github.token }} [1][2]. This token is used to make authenticated requests to GitHub, which provides a higher rate-limit quota than unauthenticated requests [1][2]. If you provide a github-token, the action automatically includes access-tokens with the provided token in the /etc/nix/nix.conf configuration file to facilitate authenticated access [1][2]. Regarding permissions: If you need to fetch private flakes or use specific FlakeHub features, the recommended approach is to use the determinate-nix-action instead of nix-installer-action [3][4]. When doing so, you must explicitly configure the permissions block in your workflow job [3][4]. For operations requiring identity tokens, ensure your job permissions include id-token: write [5]. Be aware of security considerations regarding token persistence: in non-ephemeral runner environments (such as self-hosted runners), a token written to /etc/nix/nix.conf by an initial run may persist and be used by subsequent workflow runs [6]. To ensure security and avoid stale credentials, ephemeral runner environments are recommended [6].

A compromised installer action could therefore modify repository contents or open pull requests. Run the installer with read-only permissions, then give write access only to update-flake-lock, or pass that action a narrowly scoped App or PAT token from a separate job.

site:github.com/DeterminateSystems/nix-installer-action README determinate false January 1 2026 upstream Nix

💡 Result:

The option to set determinate: false in the Determinate Systems nix-installer-action was a time-limited feature that allowed users to install "upstream Nix" instead of the default Determinate Nix [1][2][3]. According to the official documentation and repository notes, this configuration option was available only until January 1, 2026 [1][4]. As of the current date, September 6, 2026, this deadline has passed, meaning the determinate: false option is no longer supported for installing upstream Nix via this action [1][3]. The action now defaults to installing Determinate Nix, and the ability to opt out of it in favor of upstream Nix via this specific GitHub Action has been deprecated [1][2][3].

Citations:


Replace the retired upstream-Nix mode.

determinate: false is no longer supported by DeterminateSystems/nix-installer-action after January 1, 2026. This workflow may fail at the install step during scheduled or manual updates. Use a supported installer. If Determinate Nix is acceptable, use DeterminateSystems/determinate-nix-action and pin a release.

DeterminateSystems update-flake-lock action default github.token pull requests created by GitHub Actions do not trigger workflows

💡 Result:

The issue where pull requests (PRs) created by the Determinate Systems update-flake-lock action do not trigger other GitHub Actions workflows is a standard security limitation of GitHub Actions [1][2]. When a workflow uses the default GITHUB_TOKEN to create a PR, GitHub prevents the resulting events from triggering further workflows to avoid recursive loops [3]. To resolve this and ensure your CI workflows run on these automated PRs, you can use one of the following methods: 1. Use a Personal Access Token (PAT) or GitHub App Token By providing a PAT or a GitHub App installation access token instead of the default GITHUB_TOKEN, the PR is created as the user or app associated with that token, rather than the github-actions[bot]. This bypasses the restriction, allowing workflows to trigger automatically [1][3]. To implement this: - Create a PAT with repo scope (or fine-grained permissions for Contents and Pull Requests) [1][2]. - Add it as a secret (e.g., GH_TOKEN_FOR_UPDATES) to your repository [1][2]. - Configure the update-flake-lock action to use this token [1][2]: yaml - uses: DeterminateSystems/update-flake-lock@main with: token: ${{ secrets.GH_TOKEN_FOR_UPDATES }} 2. Manual Re-triggering If you do not want to use a PAT, you can trigger workflows manually by forcing a push to the branch created by the action. This effectively overrides the initial "non-triggering" state [1][2]. Run the following commands locally: sh git branch -D update_flake_lock_action git fetch origin git checkout update_flake_lock_action git commit --amend --no-edit git push origin update_flake_lock_action --force Alternatively, simply closing and re-opening the PR can also trigger the associated workflows [4][5][6]. For further details, refer to the official Determinate Systems update-flake-lock documentation [1][2].

Keep the Bun versions synchronized. The monthly or manual updater can change pkgs.bun through flake.lock, while package.json and .github/workflows/pr.yml remain pinned to Bun 1.3.13. The PR workflow does not evaluate the Nix Bun version, and no checked-in check compares these values. Add an assertion that compares all three versions, or update the explicit pins when nixpkgs changes Bun.
