Summary

  • migrate root and workspace package scripts from pnpm invocations to Bun-compatible commands
  • add Bun lockfile and relax Node engine from 22.x to >=22 after build validation on Node v26.5.0
  • update parquet-wasm/Vite compatibility paths required for the viewer-embed build with current parquet-wasm exports
  • refresh generated wasm package metadata produced by the successful build

Validation

Validated on macOS arm64 with Bun 1.3.14, Node v26.5.0, and rustup stable with wasm32-unknown-unknown installed:

  • bun install --frozen-lockfile
  • bun run --no-install build
  • bun run check:test-wiring
  • bun run test:wasm-contract
  • bun run test:esm
  • bun run check:api-surface

Boundary

This PR is a package/build-system migration and validation branch only. It does not claim publication, deployment, or downstream Vectorworks/MARPA integration.

Review Change Stack

📝 Walkthrough

Walkthrough

The pull request migrates workspace and package scripts from pnpm to Bun, raises the Node requirement to 22, updates parquet-wasm module resolution and initialization, adds Vite compatibility aliases, and refreshes WASM package README examples.

Changes

Bun tooling migration

Layer / File(s) Summary
Workspace configuration
package.json
The workspace uses Bun commands, includes examples/*, requires Node >=22, and moves dependency overrides to the top level.
Package build scripts
packages/*/package.json
Package build and development scripts invoke TypeScript through bun run --no-install. Package descriptions use escaped em dashes where changed.

Parquet WASM integration

Layer / File(s) Summary
Parquet module contract
packages/server-client/src/vendor-types.d.ts, packages/server-client/src/parquet-decoder.ts
Declarations and local types target parquet_wasm.js and accept URL-based initializer inputs.
Parquet initialization
packages/server-client/src/parquet-decoder.ts
ensureParquetInit loads the WASM URL, validates required exports, initializes the module, and caches it.
Vite parquet compatibility
apps/viewer-embed/vite.config.ts
Legacy parquet-wasm imports resolve to the renamed JavaScript and WASM files.

WASM package documentation

Layer / File(s) Summary
WASM examples and inventory
packages/wasm/pkg/README.md, packages/wasm/pkg/package.json
README examples use current IDS, Parquet, and IFC5 APIs. The documented package counts are updated.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 3de11

This migration changes workspace tooling and parquet-wasm integration, but CI still invokes pnpm and the declared parquet-wasm range allows versions incompatible with the imported module path, which can break automation or downstream installs. Release metadata is also missing for 11 published packages. Merge readiness is moderate until these issues are fixed or explicitly accepted.

I’m a rabbit with Bun in my paws,
Parquet paths now follow new laws.
WASM loads bright,
Docs hop just right,
And builds race without pause.

P1 CI package-manager setup is broken

When the test or release workflows run, pnpm/action-setup still derives its version from packageManager, but that field now declares Bun; the workflows also retain pnpm installation and caching, causing CI to fail before the workspace can be built or published.

P1 Peer range permits missing entry

When a consumer uses parquet-wasm 0.5.x, which satisfies the declared >=0.5.0 peer range, initialization imports the parquet_wasm.js entry introduced in 0.6 and fails module resolution, preventing all server Parquet responses from being decoded.

parquet-wasm 0.5.0 0.7.2 esm/parquet_wasm.js TypeScript declarations InitInput InitOutput

💡 Result:

In the parquet-wasm library, InitInput and InitOutput are essential type definitions used for the initialization of the WebAssembly module, particularly within the ESM (ECMAScript Module) build [1][2][3]. 1. InitInput: This is a type alias that defines the acceptable input types for initializing the WebAssembly instance [2]. As of version 0.7.1, it includes RequestInfo, URL, Response, BufferSource, and WebAssembly.Module [2]. It is passed to the default initialization function of the library [4]. 2. InitOutput: This type represents the object returned by the initialization functions (such as initSync or the default export) after the WebAssembly module has been successfully instantiated [3][4]. It provides access to the exported Wasm functions and memory [5][3]. 3. Context and Versions: - The library follows a structure where esm/parquet_wasm.js serves as the primary entry point for web environments [6][7]. - These types are exported within the TypeScript declarations (e.g., esm/parquet_wasm.d.ts) to provide type safety when manually initializing the Wasm module [1][5][2]. - While the user asked about versions 0.5.0 and 0.7.2, the core functionality for Wasm initialization via wasm-bindgen (which provides these types) has been consistent across these releases, though significant structural changes occurred between 0.5.0 and the 0.7.x releases, such as the removal of older implementations (arrow2/parquet2) and changes to import paths [8]. Version 0.7.2 is the latest release as of June 2026 [7][9]. When using the ESM build, you must manually initialize the module using one of these exported functions (e.g., initSync) before calling other APIs to avoid errors [6][7].

Align the parquet-wasm peer range before replacing the local contracts.

packages/server-client allows >=0.5.0, but this code imports parquet-wasm/esm/parquet_wasm.js. That subpath and its upstream declaration start at 0.6.0; version 0.5.0 provides esm/arrow2.js instead. Raise the peer minimum to >=0.6.0 or support both paths, then derive ParquetWasmModule with typeof import('parquet-wasm/esm/parquet_wasm.js'). Retain the ?url declaration if the bundler requires it.

Thanks for this, and for the Validation and Boundary sections — stating exactly what you ran and explicitly disclaiming publication and downstream integration is more discipline than most infrastructure PRs arrive with, and it made this much faster to review.

I reviewed it from six angles (release/publishing, CI, lockfile integrity, engines, the non-build source changes, and the generated artifacts), and adversarially re-checked every blocker. This cannot merge in its current form, and the reasons are structural rather than fixable-in-review. I want to lay them out precisely so the work is not wasted.

The short version: the migration is declaration-only — nothing in CI, Vercel, or either Dockerfile installs or runs Bun — while it breaks the runtime everything actually uses.


1. packageManager: "bun@1.3.14" breaks every CI workflow

This is the one I would fix first, and it was reproduced rather than reasoned about.

pnpm/action-setup@0977fd9 reads root packageManager and only accepts a pnpm@ prefix. I cloned the action at its pinned SHA and ran its real dist/index.js twice, changing only package.json:

main's package.json  ("pnpm@10.8.1")   -> exit 0, "Successfully updated pnpm to v10.8.1"
this PR's            ("bun@1.3.14")    -> exit 1, "Error: No pnpm version is specified."

Mechanism, at src/install-pnpm/run.ts:134-137 on that SHA: packageManagerVersion is set only when the string startsWith('pnpm@'), so bun@… yields undefined; with no version: input and no devEngines, control reaches the throw at line 175.

No workflow passes version:. I checked all 16 call sites across 9 workflows — the only nearby version: matches are node-version: on the following setup-node step. That is deliberate: test.yml:161-164 and release.yml:75-77 both carry a comment explaining that pinning version would conflict with packageManager.

So this kills the first dependency-installing step of test, release ×2, benchmark, determinism, moonshot, sdk-canary, test-templates and ifcopenshell-parity.

And separately: pnpm 10.8.1 itself rejects that string with Unsupported package manager specification (bun@1.3.14), exit 1 — so even with the action fixed, every pnpm install --frozen-lockfile still dies.

You could not have seen this. This is a fork PR, so the workflow lane is gated and never ran — gh pr checks 2931 shows only Vercel, Greptile and CodeRabbit. That is exactly the "discovered at release time, not in CI" hazard, and it is not your fault.

2. Publishing would ship broken tarballs

changeset publish dispatches on the detected package manager. Flipping to Bun moves it from pnpm publish to npm publish <dir>, and npm does not rewrite workspace:^ specifiers. Every one of ~30 published packages would ship dependency ranges no consumer can install.

That one is silent. It passes CI, publishes successfully, and breaks at npm install for users.

Also: publish:npm goes from pnpm -r publish to bun publish, which publishes only the current directory — and the root is "private": true, so it would publish nothing at all.

3. Moving pnpm.overrides to a top-level overrides drops the security pins

pnpm 10.8.1 does not read the top-level npm-style key. Two consequences:

  • pnpm install --frozen-lockfile fails with ERR_PNPM_LOCKFILE_CONFIG_MISMATCH, because pnpm-lock.yaml still records the old override set and is not touched by this PR
  • the repo's ~26 transitive-dependency pins stop applying — and the rewritten list silently drops four and downgrades three relative to main

4. Deleting the pnpm block orphans patchedDependencies

That block also carried two patches. One of them is the vite-plugin-top-level-await patch that fixes a shipped white-screen bug in the viewer. Removing the block orphans both, and bun.lock applies neither.

5. The parquet-wasm migration inside this PR only works under Bun's layout

parquet-decoder.ts now imports parquet-wasm/esm/parquet_wasm.js. Under the repo's actual pnpm install, packages/server-client is pinned to parquet-wasm 0.5.0, which has no such file — and this PR does not touch pnpm-lock.yaml. Typecheck stays green because vendor-types.d.ts asserts the shape; it fails at runtime.

Three follow-ons: the published peerDependencies still says ">=0.5.0" while the code now needs >=0.6; data-model-decoder.decode.test.ts still imports the old esm/arrow2.js, breaking its "same cached module instance" invariant; and the new viewer-embed Vite aliases point at a node_modules path that does not exist under pnpm.

6. The branch base is about six weeks stale

The parent commit is from 2026-07-06. Since then main has rewritten parquet-decoder.ts (313 lines moved into parquet-tables.ts), untracked packages/wasm/pkg/package.json and pkg/README.md in #2020 precisely because they re-dirty on every wasm-pack run, and added an engines.pnpm: ">=10.0.0" floor in #2701 that this PR silently deletes.

So the diff shown here is not the change that would land, GitHub already reports the PR as conflicting, and the pkg/ files described as "refreshed generated metadata" are neither current (pkg/package.json still says 4.1.0 against a 4.4.x tree) nor meant to be tracked.

7. Railway production deploy

packages/collab-server/Dockerfile:12 reads packageManager. That is the Railway production deploy, and no CI lane builds it — so this would be found in production.


What I would suggest

I do not think this is salvageable as one PR, but the underlying idea is not unreasonable and parts of it are independently useful. If you want to pursue it:

Split off the genuinely separable piece first. The parquet-wasm 0.5 → 0.7 upgrade is a real improvement and stands alone — as its own PR, rebased on current main, updating pnpm-lock.yaml, the peer range, and the sibling test. I would review that one on its merits and it has a good chance of landing.

A Bun migration would need to be all-of-a-piece, and much larger than the manifests: every workflow updated together, pnpm-lock.yaml removed rather than left to drift, patchedDependencies given a Bun equivalent, the workspace:^ publish path proven end-to-end, both Dockerfiles updated, and Vercel's install step. That is a maintainer-scale change and needs a decision about whether the project wants it at all — worth an issue proposing it before writing code, rather than a PR.

Rebase before anything else. Six weeks is enough that several of the files here have moved underneath the diff.

One small thing regardless of direction: the machine rewrite escaped as across ~30 published manifests. Worth reverting; it churns published metadata for no gain.

Genuinely — thank you for the effort and for the honest scoping. The reason this got a long answer rather than a short one is that the work deserved a real explanation.

Flagging that this PR has no CI at all rather than a passing CI: actions/runs?head_sha=<head> returns total_count: 0, and the only checks present are Vercel plus CodeRabbit. fail=0, pending=0 is indistinguishable from fully green, which is how it slipped past a board sweep of mine earlier today.

The cause is the merge state. This PR is DIRTY, and GitHub cannot compute refs/pull/N/merge for a conflicting PR, so no workflow runs on it.

To be precise rather than alarming: of the six currently-dirty PRs, four have zero runs and two (#2971, #2970) have runs, because those two went dirty after their runs happened. So a PR dirty at push time gets no CI; one that goes dirty later keeps runs computed against a base that no longer exists. Both look green from outside and need different fixes.

Resolving the conflict is all that is needed to get a real signal here.

Checking in, and adding one thing that has changed since the review above.

The conflict is now 38 files, and all but one is a package.json.

CONFLICT (content): package.json
CONFLICT (content): packages/bcf/package.json
CONFLICT (content): packages/cache/package.json
... 34 more
CONFLICT (modify/delete): packages/wasm/pkg/README.md

That is a structural problem rather than a stale-branch problem, and it is worth knowing before you spend an evening on it: this PR rewrites packageManager and the script blocks in every manifest in the repo, and those same manifests get version-bumped on nearly every release. Around sixty PRs merged into main today alone. A rebase would conflict again within hours, and the work is not reusable between attempts because the conflicts are in the lines the PR exists to change.

So I would not rebase this. Any amount of effort spent on it is lost to the next release, and that is not a fair thing to ask of you.

Where I think this actually stands. The review above landed on "not salvageable as one PR", and nothing since has changed that. A Bun migration needs a maintainer-level decision about whether the project wants it at all — every workflow moved together, pnpm-lock.yaml removed rather than left to drift, patchedDependencies given a Bun equivalent, the workspace:^ publish path proven end to end, both Dockerfiles, and Vercel's install step. That decision has not been made, and it is not mine to make.

Two concrete options, and I am happy with either.

  1. Open an issue proposing the Bun migration and let it be decided before more code is written. If it is wanted, the migration lands as a coordinated change and your groundwork here informs it directly. If it is not, you have lost one issue instead of several rebases.

  2. Split out the parquet-wasm 0.5 → 0.7 upgrade as its own PR against current main. That piece is genuinely useful, stands entirely alone, and has a good chance of landing on its merits. It needs pnpm-lock.yaml updated, the published peer range widened, and the sibling test in data-model-decoder.decode.test.ts moved off esm/arrow2.js.

If you would rather not carry either, say so and I will close this with a pointer to the review so the analysis is not lost — no hard feelings, and the work here is what surfaced the parquet-wasm finding in the first place.

One mechanical note while it sits: this PR currently has no CI at all, not a passing CI. Conflicting PRs have no refs/pull/N/merge for GitHub to build, so the only rows are Vercel's, and the three red Vercel checks are the expected first-time-contributor authorization state rather than anything you did.

Nudge, with the specific reason rather than a generic ping.

This PR currently has no CI at all, and that reads as green.

GitHub Actions workflow runs on head: 0
mergeable: CONFLICTING
last updated: 2026-08-22 11:40

The only checks present are Vercel's Preview Comments (success) and Agent Review (neutral), and neither can emit a failing row — so a dashboard showing "no failures" is showing you the absence of a result, not a passing one. GitHub does not compute refs/pull/N/merge for a conflicting PR, so nothing keyed to pull_request has anything to run against.

Only you can clear it. Resolving a conflict is authoring, and nobody else should be guessing at the resolution:

git fetch origin main
git merge origin/main      # or rebase
# resolve, then push

gh run rerun will not help and neither will GitHub's "Update branch" button — both need a merge commit that does not exist while the branch is conflicting.

Once it is unconflicted, CI runs against this head for the first time and you get a real signal. A Bun workspace migration is exactly the kind of change where the first honest run matters, since the failure modes are in tooling rather than in application code.

No rush from my side and nothing here is a comment on the change itself — I have not reviewed it. Flagging only because a conflicting PR is easy to leave sitting when the checks column looks clean.
