🎯 Changes

Solid 2 support for @tanstack/solid-store, set up as a pre-release line the way @tanstack/solid-query 6 and @tanstack/solid-router 2 were. It targets a solid-v2-pre branch, so main stays on Solid 1.

• useSelector (with useAtom, useStore and _useStore built on it) needs no API change. Its signal is written with ownedWrite, because store notifications can fire inside owned scopes such as effects. A selected function is kept as a plain value, since Solid 2's createSignal(fn) would otherwise treat it as a compute function.
• createStoreContext's StoreProvider renders the Solid 2 context with createComponent instead of JSX, so the package peers only on solid-js (>=2.0.0-rc.19 <3.0.0) and not on @solidjs/web. The context now uses a null default, so the existing "Missing StoreProvider" error still fires instead of Solid 2's own ContextNotFoundError.
• The tests call flush() after writes, because Solid 2 batches reads until the next flush. There is a new test for a selected function value.
• The five Solid examples move to @solidjs/web, @solidjs/vite-plugin and the @solidjs/web JSX import source.
• Changesets enters pre mode with the rc tag, and the release workflow also runs on *-pre branches. solid-store gets a minor bump (0.x), giving 0.12.0-rc.0. The installation docs now say which versions go with which Solid major.
• sherif ignores solid-js, because the core package's comparison benchmark stays on Solid 1.

Locally: @tanstack/solid-store tests (37/37), type checks on TS 5.6–6.0, eslint, publint, build, sherif, knip, and tsc && vite build for every Solid example. I also loaded the built store-context example in Chromium and checked that it updates on click with no console errors.

Walkthrough

The Solid store adapter and its examples now target Solid 2 release candidates. The changes also update adapter tests, installation guidance, and release configuration.

Changes: Solid 2 support

Layer / File(s)	Summary
Adapter runtime and package setup packages/solid-store/package.json, packages/solid-store/src/createStoreContext.ts, packages/solid-store/src/useSelector.ts, packages/solid-store/tsconfig*.json, packages/solid-store/tsdown.config.ts, packages/solid-store/vitest.config.ts	The adapter peer dependency now accepts solid-js versions >=2.0.0-rc.19 <3.0.0. The context provider uses createComponent with getter-backed props and a null context default. useSelector wraps an initial function value and enables ownedWrite.
Adapter tests packages/solid-store/tests/index.test.tsx	Tests flush reactive updates before assertions. A new test checks that useSelector returns a selected function as the same value.
Examples and release guidance examples/solid/*/{package.json,src/index.tsx,tsconfig.json,vite.config.ts}, docs/installation.md, .changeset/*, .github/workflows/release.yml, package.json	The Solid examples use Solid 2 release-candidate packages, the @solidjs/web renderer, and the @solidjs/vite-plugin plugin. Installation guidance distinguishes Solid 2 and Solid 1 package versions. The changeset enables rc prerelease mode, and the release workflow includes *-pre branches.

Change: Feature

Suggested reviewers: kevinvandy, crutchcorn

Merge Risk: Moderate · up to 4b949

The Solid examples cannot be installed on their own because they still pin the Solid 1 adapter. The installation docs also send Solid 2 users to the Solid 1 adapter while the release is a prerelease. Library behavior is not affected, but fix the example dependency ranges and the install command before merging.

Point Solid 2 users to the rc tag.

While prerelease mode is active, npm install @tanstack/solid-store resolves to the latest tag, which stays on the Solid 1 line (0.11.x). Changesets publishes prereleases under the dist-tag set in .changeset/pre.json, which is rc. Solid 2 users who follow this command get the 0.11 adapter. Add the rc install command for Solid 2 users until the stable 0.12 release is promoted to latest.

 npm install @tanstack/solid-store
+npm install @tanstack/solid-store@rc

<repository_evidence>
<fact source="docs/installation.md:38-46 (initial request 1 output)">The SolidJS section shows `npm install @tanstack/solid-store` with no version or tag. The next line states that 0.12 and later work with Solid 2, and that Solid 1 users should install `@tanstack/solid-store@0.11`.</fact>
<fact source="docs/installation.md (initial request 1 output)">The docs do not mention the `rc` tag or a `@rc` install command.</fact>
<fact source=".changeset/pre.json (initial request 1 output)">The file sets `"mode": "pre"` and `"tag": "rc"`.</fact>
<fact source=".changeset/solid-store-solid-2.md (initial request 1 output)">The pending changeset is a `minor` bump for `@tanstack/solid-store`, which the author describes as 0.12.0-rc.0 in the PR summary. Its text says Solid 2 requires `solid-js` `>=2.0.0-rc.19 <3.0.0`.</fact>
<fact source=".github/workflows/release.yml (initial request 1 output)">The release runs on pushes to `*-pre` branches and calls `changeset:publish`. The inspected workflow does not pass an explicit npm tag.</fact>
<inference source=".changeset/pre.json and the Changesets prerelease guide (https://changesets.dev/guide/prereleases)">In pre mode, Changesets publishes prerelease versions under the pre-mode tag, here `rc`. The `latest` tag is not moved by that publish. The `npm install` command without a tag resolves to `latest` by npm's default. Together, these show that the shown install command gives Solid 2 users the Solid 1 line (0.11) until a stable release is promoted to `latest`.</inference>
<inference source="docs/installation.md:46">The sentence "0.12 and later work with Solid 2" is accurate for version numbers. It is misleading in practice because the command above does not select that version while the prerelease is active.</inference>
<unknown>The `changeset:publish` script in package.json was not inspected, so I did not confirm that it leaves the pre-mode tag unchanged. The stable promotion to `latest` is not visible in the repository.</unknown>
<severity_note>The original comment was marked major. I downgraded it to minor. The error is limited to documentation. The next sentence in the doc gives the Solid 1 version, and a Solid 2 user can install `@rc` with a clear instruction. No runtime or data impact was shown.</severity_note>

Update the adapter dependency in all five examples.

The examples declare @tanstack/solid-store: ^0.11.2, but the workspace links the local Solid 2 adapter. A standalone npm install resolves the published 0.11.x adapter, which targets Solid 1, and can fail against solid-js: ^2.0.0-rc.19. Use the Solid 2-compatible adapter release in each example.
