Wrap svelte reactive statements with custom events to allow devtools to detect them
npm i -D svelte-reactive-preprocessor
First import the package like this
const { reactivePreprocess } = require("svelte-reactive-preprocessor");
Then in the svelte loader options, add the reactive preprocessor like this
plugins: [
  svelte({
    preprocess: reactivePreprocess(),
  }
],
If you are already using another preprocessor, add the reactive preprocessor like this
preprocess: [
  sveltePreprocess(),
  reactivePreprocess(),
],
The preprocessor options are listed below with their default values
reactivePreprocess({
  enabled: true,
  state: true,
})
Enable or disable the preprocessor
Whether to send the state to devtools. Set to false if you encounter performance issues.
