Migrate to spago v1 by pete-murphy · Pull Request #316 · purescript/trypurescript

Description of the change

Resolves #315

This migrates the client and staging Spago projects to use latest (1.0.4), and updates compiler version and package set to latest while I was at it. Note that 0.15.15 is latest version available on Hackage at time of writing.

For client updates, I just followed these instructions in Spago repo: https://github.com/purescript/spago#migrate-from-spagodhall-to-spagoyaml.

For staging/Haskell updates I followed the instructions in RELEASE.md that I also updated in these changes. I did not change stack.yaml resolver because 0.15.15 is still on lts-20.9.

This is a large diff, but most of that is in generated files. Ignoring staging/* (effectively generated from following the RELEASE.md instructions) and client/spago.lock, the diff is much more reasonable:

$ git diff origin/master --stat ':(exclude)staging/*' ':(exclude)client/spago.lock'

Oh no, I tried running locally with same memory settings as production build (set -o noglob && stack exec trypurescript -- +RTS -N2 -A128m -M3G -s -RTS 8081 $(spago sources)) and ran out of memory.

Dumping the result of investigating this with Opus: https://gist.github.com/pete-murphy/bd776708d72a00a80ba1b7e7845f2982. Option 3 seems the most attractive if it could work.

thomashoneyman · 2026-06-18T20:13:50Z

Option 3 is indeed attractive and I’m perfectly happy experimenting with reworking try PureScript, it’s definitely not received a lot of love recently.

I wouldn’t dismiss option 2 offhand — Try PureScript is browser based so certainly node packages, etc. can safely be excluded

pete-murphy · 2026-06-26T04:00:37Z

I wouldn’t dismiss option 2 offhand — Try PureScript is browser based so certainly node packages, etc. can safely be excluded

I did end up looking into Option 2 after all since it seems much easier and I am less likely to get to the harder Option 3 in near term. If I trim out Node packages & some large packages that have no dependents, I am able to run the server with (set -o noglob && stack exec trypurescript -- +RTS -N2 -A128m -M3G -s -RTS 8081 $(spago sources)) without exceeding that max heap size. The result was this commit: 0fd79d9.

The non-Node packages (largest packages with no dependents) that were omitted:

framer-motion
motion
next-purs-rsc
react-basic-dom-beta
react-icons
css-frameworks
lumi-components
yoga-sqlite
rito

#4269d0 are packages that were kept
#e0820e is omitted (because Node)
#c33d3d is omitted (because big package with no dependents)

Here's a notebook for exploring what packages to omit if it's useful: https://new.observablehq.com/@pete-murphy/try-pure-script-package-set-trim-explorer (mostly made by Opus 4.8)

The "no dependents" criterion is arbitrary, open to ideas if you can think of something that would be more fair? (Age of package, some other popularity metric...)

thomashoneyman · 2026-07-03T16:11:59Z

Quick followup on your questions in the gist:

The droplet has 3.8 GiB RAM (and no swap, though we could add it), so bumping to -M5G is off the table for now; we already overpay for trypurescript IMO so I don't want to resize upward unless absolutely necessary. So I think we should do the trimmed package set path.
I looked, and production is actually already occasionally being OOM-killed with the current package set. journalctl shows the service dying with status=9/KILL four times on April 28 and again on May 24, with Restart=always quietly recovering each time. So the existing -M3G cap plus other overhead is already (occasionally) insufficient!
I also checked the staging/output directory, and this doesn't exist on the box

I think the option 2 is the way to go, but before we merge, could you measure the trimmed set's peak (maxLive from +RTS -s) on a cold boot (no output)? If it's much above ~2.5 GB, it's probably worth trimming a little further.

Longer term, option 3 looks even better, but we don't need to do it now.

Got a little access to Fable, so ran it over this change — here are results, lightly proofread:

<---- fable ---->
Following up on the trim-criteria question with some data. I scanned every package in the untrimmed set (638 packages) for bare JS import specifiers in their foreign modules — i.e. npm/Node imports that Try PureScript cannot resolve at runtime, since the playground ships no node_modules. One important nuance: client/public/frame.html already has a JSPM import map that shims exactly seven specifiers (react, react-dom, react-dom/client, react-dom/server, big-integer, decimal.js, uuid), so the disqualifying condition is a bare import not covered by the import map.

Results, combined with the dependency graph from spago.lock:

118 packages directly contain unshimmed bare imports. Including their transitive dependents, the "cannot run in the playground" closure is 148 packages / 3,658 modules — nearly half the full set's 7,426 modules.
The current trim in 0fd79d9 cuts 79 packages / 2,945 modules, but 75 of the packages it keeps are in the cannot-run closure — they typecheck here but throw the moment you run them.
Conversely, only 6 cut packages are actually runnable: spec, spec-mocha, test-unit, pmock, react-basic-dom-beta (all its imports are shimmed), and css-frameworks (runs, though its class names do nothing without the frameworks' stylesheets in the frame).

So my suggestion: trim by "cannot execute in the playground" instead of size/dependents. It cuts ~24% more modules than the current trim (more memory headroom), it's fully principled — nothing is removed for being big or unpopular, only for being unable to run — and it lets spec, test-unit, and react-basic-dom-beta come back.

Two caveats:

Package-level is an upper bound. Some flagged packages have a single broken module (e.g. which touching child_process); a user who never imports that module is unaffected. Fine to keep borderline popular ones.
"Cannot run" is fixable, not a death sentence. Browser-friendly packages (chartjs, xterm, idb, nanoid, markdown-it-js, react-markdown, …) could be rescued with one import-map entry each via the JSPM generator. That also gives package authors a concrete path to inclusion, which answers the fairness question better than any popularity metric.

75 packages kept by the current trim that cannot run
