I use web-mode + typescript-language-server for React+TSX. Whether or not you choose to use eglot or lsp-mode, I'd still recommend following the lsp-mode performance guide: https://emacs-lsp.github.io/lsp-mode/page/performance/ https://emacs-lsp.github.io/lsp-mode/page/performance/. Those tips are useful for all setups. (use-package web-mode :ensure t :mode (("\\.ts\\'" . web-mode) ("\\.js\\'" . web-mode) ("\\.mjs\\'" . web-mode) ("\\.tsx\\'" . web-mode) ("\\.jsx\\'" . web-mode)) :config (setq web-mode-content-types-alist '(("jsx" . "\\.js[x]?\\'")))) (use-package eglot :ensure t :hook (web-mode . eglot-ensure))
