LANGUAGE TOOLS FIXES SELF-CLOSING TAG SYNTAX, ROUTER TIGHTENS QUERY PARAM VALIDATION
By RepoJournal · Filed · About Vue.js
Vue's language tools are clearing up self-closing component syntax highlighting while router adds runtime warnings for malformed query parameters.
The language-tools team shipped a fix [1] that stops marking trailing slashes in capitalized self-closing tags as invalid, treating them like void elements for consistent syntax highlighting. This closes a long-standing issue where developers got false error marks on perfectly valid custom component syntax. On the router side, a new runtime warning [2] now catches invalid query parameter formats before they cause silent bugs downstream, while a companion fix [3] explicitly allows undefined values in params so you're not penalized for sparse query objects. Language-tools also patched a tsserver fallback [4] that handles proxy write failures gracefully, keeping your IDE responsive even when module resolution hits a snag. The router team added a parameter parser playground [5] to help visualize how your query strings get parsed, plus refactored loader types into base meta [6] for cleaner type inference across route definitions.
