Major Changes

• drop support for node18 and update exports map to use default export. cjs is supported via require esm in node 20.19+ (#​1129)

• Remove experimental "advanced raw queries" feature. Basic File.svelte?raw is still supported. (#​1145)

• Using the typescript preprocessor now requires a tsconfig.json with verbatimModuleSyntax enabled, eg @​tsconfig/svelte (#​1135)

• remove support for loading commonjs svelte config files (#​1142)

• bump vite peer dependency to ^6.3.0 || ^7.0.0 (#​1130)

• define filters using object hook syntax and optimize the filter for resolveId (#​1132)

  NOTE
  include logic has changed to files matching svelteConfig.include OR svelteConfig.extensions. Previously only files matching both were loaded and transformed.

• split preprocess and compile into separate plugins (#​1145)

  It allows vite plugins to transform code between preprocess and compile, see docs and is the recommended way to replace plugin.api.sveltePreprocess usage in other vite plugins.
  You can also use vite-plugin-inspect now to inspect the result of svelte.preprocess by checking the transform of vite-plugin-svelte:preprocess

  NOTE
  This can be a breaking change in case you have other plugins besides vite-plugin-svelte transforming your svelte code
  To fix this, read the docs on how to order plugins in relation to preprocess and compile

Minor Changes

• Add experimental support for rolldown-vite (#​1135)

• replace esbuild optimizer with rolldown optimizer if rolldown-vite is used (#​1135)

• add support for loading TypeScript Svelte config files in runtimes that support it (#​1142)

  NOTE
  This change only applies to vite-plugin-svelte.

  To use svelte.config.ts in SvelteKit, with the Svelte VS Code extension or other tools reading the Svelte config file, you have to wait until support is implemented there.

Patch Changes

• reduce deprecation logging to info and allow disabling it with a flag (#​1158)

• refactor internal caching to reduce code, memory use and avoid perEnvironmentCache (#​1154)

• fix: crawl local workspace private packages devDependencies for generating vite config ssr.noExternal (#​1155)

• log known-issues link when using rolldown-vite (#​1144)

• use vite environment api internally (#​1145)

• remove vite7 beta releases from peerDependency range. (#​1151)

• deprecate plugin.api.sveltePreprocess (#​1145)
