  • (breaking) Whether or not empty elements/components should self-close is now left to the user - in other words, if you write <div /> or <Component /> that stays as is, and so does <div></div>/<Component></Component>.

2.0.0

This release comes with a rewrite of the HTML formatting. The output is now much more in line with how standard Prettier formats HTML. This is also why svelteBracketNewLine now defaults to true. Another notable default change is the sort order: svelte:options is now part of the sort order and the default changed to options-scripts-markup-styles, which is in line with how the majority of users like to order the code blocks.

The complete list of changes:

  • Rework the tag breaking logic with the goal to be more in line with how Prettier formats standard HTML. This includes respecting the user's decision to have child tags in separate lines even if they don't exceed the maximum line width (#143, #117). This is a breaking change because tags are broken up differently now than before.
  • <svelte:options> is now part of svelteSortOrder. Default sort order is now options-scripts-markup-styles. This is a breaking change. (#73)
  • svelteBracketNewLine defaults to true now to be more in line with how Prettier formats standard HTML. This is a breaking change
  • Fix formatting of fenced Svelte code blocks inside Markdown (#129)
  • Everything that is not explicitly a block element is now treated as an inline element, including components. This is a breaking change (#159)
  • Single quotes are no longer forced except inside quoted attributes/events/etc. This is a breaking change (#94)
  • If the content inside a {tag} is too long, break it up if possible (excluding {#if}/{#await}/etc. blocks). This is a breaking change (#170)
  • If the content of a <script>/<style> tag is completely empty (no whitespace), don't put the closing tag on a new line (#87)

  • Pass options to embedded parser (#162)
  • Fall back to raw text if there is a parser error in a JS expression inside a moustache tag (#163)
