feat(solid)!: add experimental Solid 2 support - #227
everton-dgn wants to merge 5 commits into
Conversation
Prepare a Solid 2 rc.13 implementation for the release strategy discussed in open-circle#202. Keep the @formisch/solid package name and propose an experimental 2.0.0-next.0 version on a separate branch. Replace removed Solid APIs, move JSX types to @solidjs/web, and preserve immediate Formisch reads while Solid batches reactive updates. Register field cleanup with the owner captured when JSX reads the ref callback. Build client and SSR entry points with Vite and preserve one shared core module for public methods and the internals export. Add adapter regressions, field lifecycle and batching tests, packaged import checks, and a dedicated Solid 2 CI workflow. Keep the Solid 1 playground on the published 1.1.x line. Validation: - pnpm test: 1,191 tests in 128 files passed, with no type errors. - lint-packages and lint-frameworks passed. - Solid client, SSR and declaration builds passed. - Client imports in jsdom and SSR package artifact checks passed. - Public package conditions and shared Valibot configuration passed. - A consumer of the generated declarations compiled without type errors. - Dedicated workflow passed actionlint. This is an experimental proposal. Publication and the coexistence of the Solid 1 and Solid 2 release lines still need maintainer agreement. SSR hydration in a real browser has not been verified. The existing ci.yml has invalid local-action paths. The dedicated Solid 2 workflow uses the valid environment action; fixing the existing workflow is outside this proposal. BREAKING CHANGE: The Solid adapter requires solid-js 2.0.0-rc.13 and @solidjs/web. Solid 1 applications should continue using @formisch/solid 1.x.

Give the Solid 2 core its own 2.0.0-next.0 identity and document the separate prerelease boundary. Keep its Solid 2 peer range truthful while stable Solid 1 consumers remain on the 1.x release line. Restore the default Solid coverage cleanup and use the repository's changelog entry verbs. Run the mocked core suite as the root Vitest project so the CLI controls typechecking without dropping the 143 type tests. Preserve the package-local compiler and isolated Solid project. Validation: - Core test script: 471 tests in 23 files, with no type errors. - Plain core vitest run: 328 runtime tests in 20 files, without typechecking. - Solid test script: 55 tests in 10 files, with no type errors. - Browser and SSR package artifact checks passed. - Frozen lockfile metadata validation and formatting passed. - Experimental core version is excluded from stable 1.x semver ranges. Publication and prerelease tags still require maintainer agreement.
The shared-core release boundary and test-configuration feedback are addressed in 2c2d31e. The release-boundary thread and the other inline replies record the changes and validation. For the docstring warning, I kept the repository's overload convention: AGENTS.md requires JSDoc only on the first overload, and repo-source-code-document explicitly omits JSDoc on the implementation. The six public Solid overload signatures retain their JSDoc, as do the core adapter's exported functions. I have not duplicated implementation docstrings to change the coverage metric. Follow-up validation passed: core 471 tests with typechecking and 328 runtime tests without it; Solid 55 tests with no type errors; browser/SSR artifacts, formatting, frozen lockfile metadata, and semver release-boundary checks. Publication remains subject to maintainer agreement. The exact Solid prerelease exceptions in |
Retract refs from registered arrays even when array methods transfer them before JSX updates. Detach inactive slots while preserving reset baselines. Add regressions for same-turn swap, remove and insert followed by disposal or conditional removal, remount and reset. Verify that other registered inputs remain intact.

Assert mutated form input and destination element identity before same-turn unmount. Keep the original DOM rows unflushed so the cleanup regression cannot pass when swap or remove does nothing.

Hey! Thank you! I already started working on that myself but didn't find time to publish it. |
Thanks, @fabian-hiller! I didn't know you had already started on this. How would you like to proceed? I can rebase onto your branch, pull out the parts that are useful to you (e.g. the field ref cleanup fix and the lifecycle/batching tests), or close this PR if yours already covers it. |

Testing the Solid 2 adapter at Without them, hydrating a native-element form reports: The local change is: // useField.ts, inside the returned element ref callback
const internalFormStore = untrack(getInternalFormStore);
const internalFieldStore = getFieldStore(internalFormStore, untrack(getPath));
// Form.tsx, inside the form ref callback
untrack(() => props.of)[INTERNAL].element = element;With these reads wrapped, the same hydration case preserves the server nodes, emits no warnings, and submits parsed nested/array/date values. Four local native/catalog hydration cases pass. This is evidence from our downstream kernel, not a claim of an independent stock-runtime reproduction; sharing the small adapter workaround in case it helps the Solid 2 port. The rc.13 ref-order changes alone did not remove the warning in this setup. Follow-up on the evidence limit: our stricter hydration claim ledger subsequently found a separate Solid Web attribute/children ID-order mismatch, reproducible without Formisch. The ref workaround above removes the reported warning; the four local checks did not yet establish complete hydration claims. We are strengthening those assertions separately. |
|
Thanks for sharing this, @gnovotny, and for clarifying the limits of the hydration checks. Could you share a minimal reproduction using the official Solid packages, with the exact versions and steps to trigger the ref-callback warning? That would help isolate the adapter behavior from the downstream kernel changes. @fabian-hiller, when you have a moment, could you let me know how you'd prefer to proceed with this proposal alongside your Solid 2 work? No rush. |

🌐 Web query:
official pnpm documentation unmet peer dependency warning strict-peer-dependencies
💡 Result:
The official pnpm docs say `strictPeerDependencies` defaults to `false`. When enabled, commands **fail** if the dependency tree has a missing or invalid peer dependency—so it turns peer-dependency problems from warnings into failures. ([pnpm.io](https://pnpm.io/settings/peer-dependencies))
To suppress missing-peer warnings selectively, use `peerDependencyRules.ignoreMissing`; for accepted version mismatches, use `peerDependencyRules.allowedVersions`. ([pnpm.io](https://pnpm.io/settings/peer-dependencies))

🌐 Web query:
pnpm official docs invalid peer dependency warning strictPeerDependencies false
💡 Result:
pnpm’s official **v10 settings docs** say `strictPeerDependencies` defaults to `false`. With it disabled, missing or invalid peer dependencies can produce warnings without making the command fail; enabling it makes commands fail for those peer-dependency issues. ([github.com](https://github.com/pnpm/pnpm.io/blob/main/versioned_docs/version-10.x/settings.md))
```yaml
# pnpm-workspace.yaml
strictPeerDependencies: false
```
This controls whether peer-dependency issues fail the command; it doesn’t suppress the warnings. To mute particular version-mismatch warnings, pnpm documents `peerDependencyRules.allowedVersions`; for missing-peer warnings, use `peerDependencyRules.ignoreMissing`. ([github.com](https://github.com/pnpm/pnpm.io/blob/main/versioned_docs/version-10.x/settings.md))

Keep the Solid serializer peer dependency aligned.
seroval-plugins@1.6.7 declares the exact peer seroval: 1.6.3, but the Solid 2 snapshots resolve it with seroval@1.6.7. With strict-peer-dependencies=false, pnpm can install this tree while emitting an invalid peer-dependency warning.
Restore the base override until a compatible seroval-plugins peer contract is available.

Prepare a Solid 2 rc.13 implementation for the release strategy discussed
in #202. Keep the @formisch/solid package name and propose an experimental
2.0.0-next.0 version on a separate branch.
Replace removed Solid APIs, move JSX types to @solidjs/web, and preserve
immediate Formisch reads while Solid batches reactive updates. Register
field cleanup with the owner captured when JSX reads the ref callback.
Build client and SSR entry points with Vite and preserve one shared core
module for public methods and the internals export. Add adapter regressions,
field lifecycle and batching tests, packaged import checks, and a dedicated
Solid 2 CI workflow. Keep the Solid 1 playground on the published 1.1.x line.
Initial migration validation:
Review follow-up:
This is an experimental proposal. Publication and the coexistence of the
Solid 1 and Solid 2 release lines still need maintainer agreement. SSR
hydration in a real browser has not been verified.
The existing ci.yml has invalid local-action paths. The dedicated Solid 2
workflow uses the valid environment action; fixing the existing workflow
is outside this proposal.
BREAKING CHANGE: The Solid adapter requires solid-js 2.0.0-rc.13 and
@solidjs/web. Solid 1 applications should continue using @formisch/solid 1.x.
