Definition

Protocol that decouples language intelligence (completion, diagnostics, find-references) from editors. typescript-7 ships a rewritten, multi-threaded language server with large latency cuts on VS Code-scale codebases.

Key Points

  • Open-with-error latency on VS Code codebase: ~17.5s → <1.3s (Microsoft)
  • Reported reductions in LS crashes (~60%) and failing commands (~80%) vs TS 6
  • Improves day-to-day UX for humans and coding-agents in IDEs
