Plugin Options

By default, this plugin will look for a svelte.config.js file in your project directory to load preprocess and compilerOptions configuration from. However, you can also customize Svelte directly via the plugin options below.

Name	Type	Description
configFilePath	string	Relative path to a Svelte config file. Defaults to load svelte.config.js from the current project root directory.
input	string[]	Array of file extensions to process. Uses svelte.config.js extensions if available. Defaults to ['.svelte'].
preprocess	svelte.preprocess options	Configure the Svelte pre-processor. If this option is given, the config file preprocess option will be ignored. If any preprocess option is set to false, preprocessing will be skipped entirely regardless of file content. If no preprocess option is given, this plugin defaults to use svelte-preprocess.
compilerOptions	svelte.compile options	Configure the Svelte compiler.If this option is given, the config file preprocess option will be ignored.
hmrOptions	svelte-hmr options	Configure HMR & "fast refresh" behavior for Svelte.
