Compare Source

Major Changes

• only prebundle files with default filenames (.svelte for components, .svelte.(js|ts) for modules) (#​901)

• remove support for Svelte 4 (#​892)

• breaking(types): some types that have been unintentionally public are now private (#​934)

• disable script preprocessing in vitePreprocess() by default because Svelte 5 supports lang=ts out of the box (#​892)

• replaced svelte-hmr with Svelte 5 compiler hmr integration (#​892)

Minor Changes

• allow infix notation for svelte modules (#​901)

  Previously, only suffix notation .svelte.js was allowed, now you can also use .svelte.test.js or .svelte.stories.js.
  This helps when writing testcases or other auxillary code where you may want to use runes too.

• feat(config): dynamically extract list of svelte exports from peer dependency so that new exports work automatically" (#​941)

• feat(warnings): change default loglevel of warnings originating from files in node_modules to debug. To see them call DEBUG:vite-plugin-svelte:node-modules-onwarn pnpm build. (#​989)

Patch Changes

• fix: make defaultHandler a required argument for onwarn in plugin options (#​895)

• prebundle with dev: true by default (#​901)

• fix(dev): compile with hmr: false for prebundled deps as hmr does not work with that (#​950)

• fix: ensure svelte modules correctly run in DEV mode (#​906)

• ensure consistent use of compileOptions.hmr also for prebundling (#​956)

• fix(optimizeDeps): avoid to optimise server only entrypoints of svelte that are never used on the client (#​941)

• update peer on workspace packages to avoid packages bumping each other (#​916)

• export PluginOptions interface (#​976)

• Remove log about experimental status of Svelte 5. Note that breaking changes can still occur while vite-plugin-svelte 4 is in prerelease mode (#​894)

• fix: ensure vite config is only resolved once during lazy init of vitePreprocess (#​912)

• fix(vitePreprocess): default to build config so that svelte-check does not trigger dev-only plugins (#​931)

• fix: only apply infix filter to basename (#​920)

• fix: disable hmr when vite config server.hmr is false (#​913)

• fix(dev): make sure custom cssHash is applied consistently even for prebundled components to avoid hash mismatches during hydration (#​950)

• Updated dependencies [22baa25, 49324db, e9f048c, 213fedd]:

  • @​sveltejs/vite-plugin-svelte-inspector@​3.0.0
