tivac / svelte-trim

Strips whitespace from svelte files.

svelteTrim

Trims unwanted whitespace out from between <dom nodes="">, <Components />, {tags}, and {#blocks} of svelte files.

Usage:

Place as the last preprocessor in your svelte.config.js's preprocess field. If you us any other preprocessors, wrap them in a call to asMarkupPreprocessor.

Warning! Currently, we must be run on valid/pure svelte files! This means any other preprocessors you use must run before us. Due to how svelte.preprocess works, just placiing them before us will not be enough. You must additionaly wrap them in svelte-as-markup-preprocessor. See their readme for an explanation of why this is necessary.

// svelte.config.js
const {asMarkupPreprocessor} = require('svelte-as-markup-preprocessor')
const sveltePreprocess = require('svelte-preprocess')
const {mdsvex} = require('mdsvex')
const {svelteTrim} = require('svelte-trim')
module.exports = {
  preprocess: [
    asMarkupPreprocessor([
      sveltePreprocess(),
      mdsvex()
    ]),
    svelteTrim({
      removalMethod: 'trim'
      multiline: true,
      inline: false
    })
  ]
}
