"Visit tags table" prompt on jumping to definition?

[dbarros]

When I press the bound M-. to jump to a definition, I am prompted with:

Visit tags table (default TAGS): ~/projects/app/

I've double-checked the installation requirements, but am not able to avoid this prompt. Is there something you can recommend I try?

First try using AST of the js2-mode. If it fails, fall back to xref.

(defun my-js-jump-to-definition ()
  "Jump to a definition."
  (interactive)
  ;; (tern-find-definition)
  (condition-case-unless-debug nil
      (js2-jump-to-definition)
    (error
     (xref-pop-marker-stack)
     (xref-find-definitions (xref-backend-identifier-at-point (xref-find-backend))))))



(define-key js2-mode-map (kbd "M-.") #'my-js-jump-to-definition)
(add-hook 'xref-backend-functions #'xref-js2-xref-backend nil t)

You should set the xref backend in js2 buffers:

(add-hook 'js2-mode-hook (lambda ()
  (add-hook 'xref-backend-functions #'xref-js2-xref-backend nil t)))

@dbarros are you using js2 and Emacs >= 25.1?

[dbarros]

@NicolasPetton Yes, I have js2 and Emacs 25.2

Ok, and have you setup xref-js2 as described in the README?
