Khaled Waleed	2d2e5df26e	fix: don't turn component instances stored in $state into state proxies (#18646) ... Fixes #18416. We previously said that we don't want to handle component instances specifically when they're wrapped with state in #16747 - though the use case presented back then was much more arcane than the one in #18416. Therefore we now don't proxify component instances anymore, which also makes the dev time proxy warning obsolete. --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Simon Holthausen <simon.holthausen@vercel.com> Co-authored-by: Simon H <5968653+dummdidumm@users.noreply.github.com>	3 weeks ago

Minh Lê	94bd27953e	docs: fix invalid `rows` CSS property in {#each} chess-board example (#18367) ... ## Problem The `{#each}` docs page has a runnable "chess board" example whose `<style>` block uses an invalid CSS property: ```css .chess-board { display: grid; grid-template-columns: repeat(8, 1fr); rows: repeat(8, 1fr); /* ← not a real CSS property */ ... } ``` There is no `rows` shorthand or longhand in CSS, so this line is silently dropped by every browser. The example clearly intends an 8×8 grid (note the matching `grid-template-columns` line directly above). ## Fix `rows` → `grid-template-rows`. One line, in `documentation/docs/03-template-syntax/03-each.md`. No prose changes.	3 months ago

Mathias Picker	27e74c4df7	docs: add auto-generated browser support page (#18276) ... ## Summary Adds a [Browser support](https://github.com/MathiasWP/svelte/blob/document-pipeline-draft/documentation/docs/07-misc/05-browser-support.md) page listing the minimum browser versions Svelte's runtime and compiler output require. The page (headline floor + per-feature requirements) is auto-generated by `packages/svelte/scripts/generate-browser-support.js`, which scans the code Svelte actually ships against the [web-features](https://github.com/web-platform-dx/web-features) Baseline dataset and resolves results to concrete browser versions via [baseline-browser-mapping](https://github.com/web-platform-dx/baseline-browser-mapping). CI fails if a PR moves the floor without regenerating the page. For 5.55.9 the floor is **Baseline 2020**: Chrome/Edge 87, Firefox 83, Safari 14. ## How it works 1. **Headline floor.** Each runtime entry from `pkg.exports` is bundled with rollup using production conditions, then walked with TypeScript's compiler API + TypeChecker. The walker (`browser-support.detector.js`) flags any web-features ID the runtime references; the highest Baseline year among them is the floor. 2. **Per-feature requirements.** Every user-facing surface is enumerated programmatically — every `bind:*` from `binding_properties`, every public subpackage export discovered via `pkg.exports` + `import * as ns`, every rune from `RUNES`, and directives (`transition:` / `animate:` / `use:` / `@attach` / `{@html}` / custom elements). Each gets a fixture, compiled and bundled like user code, then scanned. A row appears only when the fixture's floor exceeds the runtime floor. 3. **Supplemental rules.** A handful of APIs `web-features` doesn't catalogue (`getComputedStyle(...).zoom`, `box: 'device-pixel-content-box'`) are detected with the same type-aware walker via a small `register_extra_rules` list with inline justifications. 4. **Ignore sets.** `SAFE_TO_IGNORE` covers dataset bugs and feature-detected APIs with graceful fallbacks. `BEHAVIORAL_IGNORE` hides APIs reached only via specific user code from the headline (they still surface as conditional rows); staleness-checked, so CI fails if an entry no longer exists in the runtime. Resolves #18198. Provides an answer to the long-standing #558. ## Test plan - [ ] \`pnpm --filter svelte generate:browser-support\` regenerates the page idempotently - [ ] CI fails when a code change bumps the floor without regenerating the page - [ ] Page renders correctly on svelte.dev 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> Co-authored-by: Rich Harris <rich.harris@vercel.com>	3 months ago

Rich Harris	0da9f9e2ab	fix: disallow effect creation after `await` (#18299) ... We incorrectly restore effect context after an`$derived(await ...)` if it occurs inside an async function, but only for those, no other `await` expressions. This is buggy and wrong. We only want to restore context _inside_ an async derived expression (including template expressions)` so that `await a + b` works correctly. It's possible that this will be a breaking change (albeit not semver-violating, because `experimental`) for some people if they are creating effects after an `await` (other than at the top level of a component). This is regrettable, but it should never have worked in the first place.	4 months ago

RonGamzu	d2c7fa3494	fix: use consistent spelling in script_unknown_attribute warning (#18281) ... ## Summary The `script_unknown_attribute` warning message used American English (`Unrecognized`) while every other user-facing error/warning in the compiler uses British English (`Unrecognised`): - `options_unrecognised` error: `Unrecognised compiler option…` - `unknown_code` warning: `is not a recognised code` This change updates `script_unknown_attribute` to match, then regenerates `warnings.js` and the reference documentation from the source message file via `node scripts/process-messages`. ## Test plan - Spelling change is isolated to the `script_unknown_attribute` warning message - `warnings.js` and generated docs were updated by running `node scripts/process-messages` - All three occurrences (source, generated JS, generated docs) are consistent	4 months ago

Ref: https://github.com/sveltejs/svelte/issues/15100 Adds the tag name to the `a11y_click_events_have_key_events` warning given when a non-interactive element has a click handler but no keyboard events. This already happens in `a11y_no_static_element_interactions`, and should probably happen in many more messages.	4 months ago

Mukunda Rao Katta	a63bf862c0	docs: clarify context state getter pattern (#18226) ... Closes #18022 This updates the context docs to show the getter pattern for state that may be reassigned, such as primitive state. The new example passes a function through context so children read the current value instead of capturing the initial value. This is a docs-only clarification and does not change runtime behavior. Validation: - `git diff --check` - `pnpm exec prettier --check documentation/docs/06-runtime/02-context.md` Full `pnpm test`/`pnpm lint` were not run because this only changes documentation. --------- Co-authored-by: Rich Harris <hello@rich-harris.dev>	4 months ago

Rich Harris	0e9e76f292	fix: freeze deriveds once their containing effects are destroyed (#17921) ... Per https://github.com/sveltejs/svelte/pull/17862#issuecomment-4049752548, this freezes the value of a derived if it was created inside a parent effect that is now destroyed. This prevents the sort of bug where a derived reads `foo.bar` even though `foo` is now `undefined`. If the derived is dirty, a warning will be printed. This PR also gets rid of some weirdness around `derived.parent` — it can only ever be an `Effect | null`, and there's no need for `get_derived_parent_effect`. Blocked on https://github.com/sveltejs/kit/pull/15533 and a follow-up that switches remote functions to use `$effect.root` (since this effectively undoes #17171), hence draft. ### Before submitting the PR, please make sure you do the following - [x] It's really useful if your PR references an issue where it is discussed ahead of time.
