- 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

- 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,

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

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-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 Show the details of the error at point.
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.

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.
The number of seconds to wait for a sync response.
List of extra environment variables to use when starting tsserver.
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.
Name or path of the node executable binary file.
Hook run after code edits are applied in a buffer.
Whether completions should be sorted by kind.
Format options plist.
tide-user-preferences `'(:includeCompletionsForModuleExports t :includeCompletionsWithInsertText t :allowTextChangesInNewFiles t)
`
User preference plist used on the configure request.
Check https://github.com/Microsoft/TypeScript/blob/17eaf50b73c1355d2fd15bdc3912aa64a73483dd/src/server/protocol.ts#L2684 for the full list of available options.
Disable suggestions.
If set to non-nil, suggestions will not be shown in flycheck errors and tide-project-errors buffer.
CASE will be ignored in completion if set to non-nil.
Completion dropdown will contain detailed method information if set to non-nil.
Whether to include external module exports in completions.
The filter for items returned by tide-nav. Defaults to class, interface, type, enum
Reuse existing window when jumping to definition.
Imenu index will be flattened if set to non-nil.
`
The list of commands where popup selection is allowed.
Show the documentation window even if only type information is available.
Maximum allowed response length from tsserver. Any response greater than this would be ignored.
Function used by tide to locate tsserver.
The default mode to open buffers not backed by files (e.g. Org source blocks) in.
Recenter buffer after jumping to definition
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.
How long to wait after user input before highlighting the current identifier.
