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
Create jsconfig.json
in the root folder of your project.
jsconfig.json
is tsconfig.json
with allowJs
attribute set to
true.

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 Load the documentation for the
symbol at point to buffer *tide-documentation*
.
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-project-errors List all errors in the project. Errors can be navigated using n and p. Press enter to open the file.
M-x tide-error-at-point Load the details of the error at point
to buffer *tide-error*
.
M-x tide-rename-symbol Rename all occurrences of the symbol at point.
M-x tide-rename-file Rename current file and all it's references in other files.
M-x tide-format Format the current region or buffer.
M-x tide-fix Apply code fix for the error at point. When invoked with a prefix arg, apply code fix for all the errors in the file that are similar to the error at point.
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-refactor Refactor code at point or current region.
M-x tide-jsdoc-template Insert JSDoc comment template at point.
M-x tide-verify-setup Show the version of tsserver.
M-x tide-organize-imports Organize imports in the file.
M-x tide-list-servers List the tsserver
processes launched by
tide.
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 the minibuffer?
Tide has the command tide-documentation-at-point
to load the
documentation for the symbol at point to buffer *tide-documentation*
from where it can be copied. By default, tide will not open this buffer
if only type information is available. This behavior can be
overridden by setting (setq tide-always-show-documentation t)
2
The number of seconds to wait for a sync response.
nil
List of additional flags to provide when starting tsserver.
'nil
List of extra environment variables to use when starting tsserver.
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.
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.
"node"
Name or path of the node executable binary file.
nil
List of flags to provide to node when starting tsserver.
Useful for large TypeScript codebases which need to set max-old-space-size to a higher value.
nil
Hook run after code edits are applied in a buffer.
nil
Whether completions should be sorted by kind.
'nil
Format options plist.
'(:includeCompletionsForModuleExports t :includeCompletionsWithInsertText t :allowTextChangesInNewFiles t :generateReturnInDocTemplate t)
User preference plist used on the configure request.
Check https://github.com/Microsoft/TypeScript/blob/17eaf50b/src/server/protocol.ts#L2684 for the full list of available options.
nil
Disable suggestions.
If set to non-nil, suggestions will not be shown in flycheck errors and tide-project-errors buffer.
t
Add company-tide
to company-backends
.
nil
CASE will be ignored in completion if set to non-nil.
nil
Completion dropdown will contain completion source if set to non-nil.
nil
Allow fuzzy completion.
By default only candidates with exact prefix match are shown. If set to non-nil, candidates with match anywhere inside the name are shown.
nil
Completion dropdown will contain detailed method information if set to non-nil.
t
Whether to include external module exports in completions.
t
Whether to enable xref integration.
#'tide-navto-item-filter-default
The filter for items returned by tide-nav. Defaults to class, interface, type, enum
t
Reuse existing window when jumping to definition.
nil
Imenu index will be flattened if set to non-nil.
'(code-fix refactor)
The list of commands where popup selection is allowed.
nil
Show the documentation window even if only type information is available.
102400
Maximum allowed response length from tsserver. Any response greater than this would be ignored.
#'tide-tsserver-locater-npmlocal-projectile-npmglobal
Function used by tide to locate tsserver.
60
The number of idle seconds to wait before cleaning up unused tsservers.
Use nil
to disable automatic cleanups. See also tide-do-cleanups
.
'immediate
The method by which tide starts tsserver. immediate
causes tide to start a tsserver instance
as soon as tide-mode
is turned on. manual
means that tide will start a tsserver only when the
user manually starts one.
"TS"
The default mode to open buffers not backed by files (e.g. Org source blocks) in.
t
Recenter buffer after jumping to definition
#'tide-jump-to-fallback-not-given
The fallback jump function to use when implementations aren't available.
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.
(>= emacs-major-version 27) (functionp 'json-serialize) (functionp 'json-parse-buffer) (functionp 'json-parse-string))`
Use native JSON parsing (only emacs >= 27).
t
Save the buffer after applying code edits.
0.5
How long to wait after user input before highlighting the current identifier.
