Make eglot support tsx

init-ts.el

(define-derived-mode typescriptreact-mode web-mode "TypescriptReact"
  "A major mode for tsx.")

(use-package typescript-mode
  :mode (("\\.ts\\'" . typescript-mode)
         ("\\.tsx\\'" . typescriptreact-mode)))

(use-package eglot
  :ensure t
  :defer 3
  :hook
  ((js-mode
    typescript-mode
    typescriptreact-mode) . eglot-ensure)
  :config
  (cl-pushnew '((js-mode typescript-mode typescriptreact-mode) . ("typescript-language-server" "--stdio"))
              eglot-server-programs
              :test #'equal))

That works perfect for me, thanks. But the closing parenthesis at the end of line 14 seems extra, and I needed to remove it.

thanks for your comment, i've fixed it according your feedback. 👍
