TypeScript Interactive Development Environment for Emacs
Installation
- Tide requires Emacs 25 or later. We recommend Emacs 27 or later with native json support.
- Install node.js v0.12.0 or greater.
- Make sure tsconfig.json or jsconfig.json is present in the root folder of the project.
- Tide is available in melpa. You can install tide via package-install M-x package-install [ret] tide
Configuration
TypeScript
(defun setup-tide-mode ()
(interactive)
(tide-setup)
(flycheck-mode +1)
(setq flycheck-check-syntax-automatically '(save mode-enabled))
(eldoc-mode +1)
(tide-hl-identifier-mode +1)
;; company is an optional dependency. You have to
;; install it separately via package-install
;; `M-x package-install [ret] company`
(company-mode +1))
;; aligns annotation to the right hand side
(setq company-tooltip-align-annotations t)
;; formats the buffer before saving
(add-hook 'before-save-hook 'tide-format-before-save)
(add-hook 'typescript-mode-hook #'setup-tide-mode)
Format options
Format options can be specified in multiple ways.
- via elisp
(setq tide-format-options '(:insertSpaceAfterFunctionKeywordForAnonymousFunctions t :placeOpenBraceOnNewLineForFunctions nil))
- via tsfmt.json (should be present in the root folder along with tsconfig.json)
{
"indentSize": 4,
"tabSize": 4,
"insertSpaceAfterOpeningAndBeforeClosingTemplateStringBraces": false,
"placeOpenBraceOnNewLineForFunctions": false,
"placeOpenBraceOnNewLineForControlBlocks": false
}
Check here for the full list of supported format options.
(require 'web-mode)
(add-to-list 'auto-mode-alist '("\\.tsx\\'" . web-mode))
(add-hook 'web-mode-hook
(lambda ()
(when (string-equal "tsx" (file-name-extension buffer-file-name))
(setup-tide-mode))))
;; enable typescript-tslint checker
(flycheck-add-mode 'typescript-tslint 'web-mode)
Tide also provides support for editing js & jsx files. Tide checkers
javascript-tide
and jsx-tide
are not enabled by default for js &
jsx files. It can be enabled by setting flycheck-checker
JavaScript
Create jsconfig.json
in the root folder of your project.
jsconfig.json
is tsconfig.json
with allowJs
attribute set to
true.
{
"compilerOptions": {
"target": "es2017",
"allowSyntheticDefaultImports": true,
"noEmit": true,
"checkJs": true,
"jsx": "react",
"lib": [ "dom", "es2017" ]
}
}
(add-hook 'js2-mode-hook #'setup-tide-mode)
;; configure javascript-tide checker to run after your default javascript checker
(flycheck-add-next-checker 'javascript-eslint 'javascript-tide 'append)
(require 'web-mode)
(add-to-list 'auto-mode-alist '("\\.jsx\\'" . web-mode))
(add-hook 'web-mode-hook
(lambda ()
(when (string-equal "jsx" (file-name-extension buffer-file-name))
(setup-tide-mode))))
;; configure jsx-tide checker to run after your default jsx checker
(flycheck-add-mode 'javascript-eslint 'web-mode)
(flycheck-add-next-checker 'javascript-eslint 'jsx-tide 'append)
Use Package
(use-package tide
:ensure t
:after (typescript-mode company flycheck)
:hook ((typescript-mode . tide-setup)
(typescript-mode . tide-hl-identifier-mode)
(before-save . tide-format-before-save)))
Commands
Keyboard shortcuts | Description |
---|---|
M-. | Jump to the definition of the symbol at point. With a prefix arg, Jump to the type definition. |
M-, | Return to your pre-jump position. |
M-x tide-restart-server Restart tsserver. This would come in handy after you edit tsconfig.json or checkout a different branch.
M-x tide-documentation-at-point Show documentation for the symbol at point.
M-x tide-references List all references to the symbol at point in a buffer. References can be navigated using n and p. Press enter to open the file.

M-x tide-add-tslint-disable-next-line If the point is on
one or more tslint errors, add a tslint:disable-next-line
flag on
the previous line to silence the errors. Or, if a flag already exists
on the previous line, modify the flag to silence the errors.

M-x tide-jsdoc-template Insert JSDoc comment template at point.
M-x tide-verify-setup Show the version of tsserver.

Debugging
Tide uses
tsserver as the
backend for most of the features. It writes out a comprehensive log
file which can be captured by setting
tide-tsserver-process-environment
variable.
(setq tide-tsserver-process-environment '("TSS_LOG=-level verbose -file /tmp/tss.log"))
How do I configure tide to use a specific version of TypeScript compiler?
For TypeScript 2.0 and above, you can customize the
tide-tsserver-executable
variable. For example
(setq tide-tsserver-executable "node_modules/typescript/bin/tsserver")
Sadly, this won't work for TypeScript < 2.0. You can clone the repo locally and checkout the old version though.
How do I copy the type information shown in minibuffer?
Tide has tide-documentation-at-point
command to show the
documentation for the symbol at point. By default, it will not show
the buffer if only type information is available. This behavior can be
overridden by setting (setq tide-always-show-documentation t)
Custom Variables
tide-sync-request-timeout 2
The number of seconds to wait for a sync response.
tide-tsserver-flags nil
List of additional flags to provide when starting tsserver.
tide-tsserver-process-environment 'nil
List of extra environment variables to use when starting tsserver.
tide-tsserver-executable nil
Name of tsserver executable to run instead of the bundled tsserver.
This may either be an absolute path or a relative path. Relative paths are resolved against the project root directory.
Note that this option only works with TypeScript version 2.0 and above.
tide-tscompiler-executable nil
Name of tsc executable.
This may either be an absolute path or a relative path. Relative paths are resolved against the project root directory.
tide-node-executable "node"
Name or path of the node executable binary file.

Useful for large TypeScript codebases which need to set max-old-space-size to a higher value.
tide-post-code-edit-hook nil
Hook run after code edits are applied in a buffer.

tide-allow-popup-select '(code-fix refactor)
The list of commands where popup selection is allowed.
tide-always-show-documentation nil
Show the documentation window even if only type information is available.
tide-server-max-response-length 102400

The fallback jump function to use when implementations aren't available.
tide-filter-out-warning-completions nil
Completions whose :kind
property is "warning" will be filtered out if set to non-nil.
This option is useful for Javascript code completion, because tsserver often returns a lot of irrelevant
completions whose :kind
property is "warning" for Javascript code. You can fix this behavior by setting
this variable to non-nil value for Javascript buffers using setq-local
macro.
