Simon H	d083f8a3f2	feat: custom elements rework (#8457) ... This is an overhaul of custom elements in Svelte. Instead of compiling to a custom element class, the Svelte component class is mostly preserved as-is. Instead a wrapper is introduced which wraps a Svelte component constructor and returns a HTML element constructor. This has a couple of advantages: - component can be used both as a custom element as well as a regular component. This allows creating one wrapper custom element and using regular Svelte components inside. Fixes #3594, fixes #3128, fixes #4274, fixes #5486, fixes #3422, fixes #2969, helps with https://github.com/sveltejs/kit/issues/4502 - all components are compiled with injected styles (inlined through Javascript), fixes #4274 - the wrapper instantiates the component in `connectedCallback` and disconnects it in `disconnectedCallback` (but only after one tick, because this could be a element move). Mount/destroy works as expected inside, fixes #5989, fixes #8191 - the wrapper forwards `addEventListener` calls to `component.$on`, which allows to listen to custom events, fixes #3119, closes #4142 - some things are hard to auto-configure, like attribute hyphen preferences or whether or not setting a property should reflect back to the attribute. This is why `<svelte:options customElement={..}>` can also take an object to modify such aspects. This option allows to specify whether setting a prop should be reflected back to the attribute (default `false`), what to use when converting the property to the attribute value and vice versa (through `type`, default `String`, or when `export let prop = false` then `Boolean`), and what the corresponding attribute for the property is (`attribute`, default lowercased prop name). These options are heavily inspired by lit: https://lit.dev/docs/components/properties. Closes #7638, fixes #5705 - adds a `shadowdom` option to control whether or not encapsulate the custom element. Closes #4330, closes #1748 Breaking changes: - Wrapped Svelte component now stays as a regular Svelte component (invokeing it like before with `new Component({ target: ..})` won't create a custom element). Its custom element constructor is now a static property named `element` on the class (`Component.element`) and should be regularly invoked through setting it in the html. - The timing of mount/destroy/update is different. Mount/destroy/updating a prop all happen after a tick, so `shadowRoot.innerHTML` won't immediately reflect the change (Lit does this too). If you rely on it, you need to await a promise	3 years ago
Tan Li Hau	df2f656557	feat: improve hydration, claim static html elements using innerHTML instead of deopt to claiming every nodes (#7426) ... Related: #7341, #7226 For purely static HTML, instead of walking the node tree and claiming every node/text etc, hydration now uses the same innerHTML optimization technique for hydration compared to normal create. It uses a new data-svelte-h attribute which is added upon server side rendering containing a hash (computed at build time), and then comparing that hash in the client to ensure it's the same node. If the hash is the same, the whole child content is expected to be the same. If the hash is different, the whole child content is replaced with innerHTML. --------- Co-authored-by: Simon H <5968653+dummdidumm@users.noreply.github.com> Co-authored-by: Ben McCann <322311+benmccann@users.noreply.github.com> Co-authored-by: Simon Holthausen <simon.holthausen@vercel.com>	3 years ago

Maxime LUCE	0cf5511ae0	[feat] Add errorMode option to compile to allow continuing on errors (and mark them as warnings) (#6194) ... This PR adds a new option errorMode to CompileOptions to allow continuing the compilation process when errors occured. When set to warn, this new option will indicate to Svelte that it should log errors as warnings and continue compilation. This allows (notably) preprocessors to compile the markup to detect vars in markup before preprocessing (in this case: script and style tags are stripped so it can produce a lot of errors). This PR is part of a work on the svelte-preprocess side to improve the preprocessing of TypeScript files: https://github.com/sveltejs/svelte-preprocess/issues/318 - allow compiler to pass error as warnings - enforce stops after errors during compilation (for type-checking, TS doesn't know the error method throws) - should review Element.ts:302 - added a test case for errorMode - added documentation	4 years ago
