TypeScript Definition manager for DefinitelyTyped


TypeScript Definition manager for DefinitelyTyped

TSD is a package manager to search and install TypeScript definition files directly from the community driven DefinitelyTyped repository.

  • It is recommended you check-in the definitions you install into your VCS.
  • Don't forget to move your fixes back to DefinitelyTyped

The Github API has a 60-requests-per-hour rate-limit for non-authenticated use. You'll likely never hit this as TSD uses local caching and the definition files are downloaded from Github RAW urls. Optionally a scope-limited Github OAuth token can be used to boost the limit to 5000.

The CLI tool tracks some anonymous usage statistics about what definitions are installed though TSD in Google Analytics (using universal-analytics). There is also a update-notifier service to check for TSD updates.

Install global using node using npm:

$ npm install tsd -g

For previews and history check the release tags.

Global tsd binary:

$ tsd -h

Sometimes it looks like this:

Create a new tsd.json:

$ tsd init

Minimal query for d3:

$ tsd query d3

Tip: if you are using Linux or Mac OS X, use $ tsd query "*".

Get some info about jquery:

$ tsd query jquery --info --resolve
$ tsd query jquery -i -r
$ tsd query jquery -ir

Search for jquery plugins:

$ tsd query */jquery.*

View mocha history:

$ tsd query mocha --history
$ tsd query mocha -y

List everything:

$ tsd query *

Browse pixi definition on github:

$ tsd query pixi --action browse
$ tsd query pixi -a browse

Visit gruntjs homepage:

$ tsd query gruntjs --action visit
$ tsd query gruntjs -a visit

Install mocha, chai and sinon definitions all at once:

$ tsd query mocha chai sinon --action install
$ tsd query mocha chai sinon -a install

Install bootstrap definitions:

$ tsd query bootstrap --action install
$ tsd query bootstrap -a install

Solve the reference to jquery, overwrite existing files and save to the tsd.config:

$ tsd query angular --resolve --overwrite --save --action install
$ tsd query angular -r -o -s -a install
$ tsd query angular -rosa install

Install and save to test.d.ts as <reference/> bundle:

$ tsd query mocha chai -r -o -s -a install -b test

TSD uses a (globbing) path + filename selector to query the DefinitelyTyped index. The results can then be modified using various filters:

Note how the definition filename takes priority:

$ tsd query module
$ tsd query project/module

For example, consider these definitions:


Notice the pattern, and ignore the .d.ts extension:


Select definitions using only the module name:

$ tsd query module
$ tsd query module-addon

Or use a selector derived from the path format:

$ tsd query project/module
$ tsd query other/module

The selector also supports globbing, for example:

$ tsd query project/*
$ tsd query project*
$ tsd query module*
$ tsd query project/module*
$ tsd query project-*/plugin*
$ tsd query *project*/*
$ tsd query project/plugin*
$ tsd query other/module
$ tsd query */module
$ tsd query */module-*
$ tsd query */*plugin

Globbing implements only leading and trailing (for now).

Note: the semver postfix of definition files is expected to be separated by a dash and possibly a 'v'


If there are multiple matches with same module name they will be prioritised:

  1. The unversioned name is considered being most recent.
  2. Then versions are compared as expected following these comparison rules.
  3. Use the --version / -v option to set a semver-range:
$ tsd query node -v latest
$ tsd query node -v all
$ tsd query node -v ">=0.8 <0.10"
$ tsd query node -v "<0.10"

Use the --date / -d option to set a date-range (find dates using --history / -y):

$ tsd query d3 --history
$ tsd query d3 --date ">=2012-01-01"
$ tsd query d3 -y
$ tsd query d3 -d "<2012-01-01"

Use the --commit / -c option to supply sha1-hash of a commit (find a commit hash using --history), for convenience a shortened sha1 hash is supported.

$ tsd query youtube --history
$ tsd query youtube --date d6ff
$ tsd query youtube -y
$ tsd query youtube -c d6ff


  1. For now this only works with commits that actually changed the definition file you selected (eg, listed in --history) This will be expanded to allow selecting from any commit at a later date.

TSD can be used as a JavaScript npm dependency:

var tsd = require('tsd');
var api = new tsd.API(new tsd.Context('path/to/tsd-config.json'));
api.search(new tsd.Selector('jquery/*')).then(function(res) {
    // yes 
}, function(err) {
    // no 

For a practical example see grunt-tsd.

TSD uses Promise/A+ by kriskowal/q and kriskowal/q-io packages. :point_left::+1:

Note: Keep in mind this project started as a <reference> style TypeScript v0.8.x single-file compile target, which makes it harder to limit the exported API compared to import multi-file style. This is also why the definitions include more then just the tsd namespace.

API export is somewhat experimental; take care to lock versions and test on upgrade. If you plan to use TSD as module in a tool or project then feel free to leave a message and coordinate stuff.

Not yet.

The tsd.json file is automatically created in the root of each project: it configures TSD and it tracks the definitions that are installed (using --save). See the JSON Schema for more info.

The tsd.d.ts file links every definition that is installed (with --save) for convenient reference:

/// <reference path="../typings/tsd.d.ts" />

By default it is created in the typings folder but it is configurable in tsd.json. TSD will check the existing references and respects re-ordering.

This is a optional JSON encoded file to define global settings. TSD looks for it in the user's home director (eg: %USERPROFILE% on Windows, $HOME / ~ on Linux), and in the current working directory.

  • "proxy" - Use a http proxy

Any standard http-proxy as supported by the request package.

    "proxy": "http://proxy.example.com:88"
  • "token" - Github OAuth token:

The OAuth token can be used to boost the Github API rate-limit from 60 to 5000 (non-cached) requests per hour. The is token needs just 'read-only access to public information' so no additional OAuth scopes are necessary.

    "token": "0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33"

You can create this token on Github.com:

  1. Go to https://github.com/settings/tokens/new
  2. Deselect all scopes to create a token with just basic authentication.
    1. (verify you really deselected all scopes)
    2. (wonder why these presets were set??)
  3. Enter a identifying name, something like "TSD Turbo 5000"
  4. Create the token.
  5. Copy the hex-string to the token element in the .tsdrc file.
  6. Verify enhanced rate-limit using $ tsd rate

Change or revoke the token at any time on https://github.com/settings/applications

Note: keep in mind the .tsdrc file is not secured. Don't use a token with additional scope unless you know what you are doing.

The bare 'no scope' token is relatively harmless as it gives 'read-only access to public information', same as any non-autenticated access. But it does identify any requests done with it as being yours, so it is still your responsibility to keep the token private.

Of course! The official plugin is grunt-tsd.

If TSD is used in a way that needs many unique API calls in a short period (like using --history on big selections), or shares an internet-connection with multiple users (like in an office) then the rate limit blocks the API. It blocks for 60 minutes after the first request of the total 60.

For these cases TSD has an option to use a Github OAuth token and raise your local rate-limit from 60 to 5000 per hour. See the .tsdrc-section elsewhere in the readme.

As of v0.5.7 there are two ways to configure the location of the proxy server:

  1. Use a environment variable. TSD support the conventional fields: pick one of HTTPS_PROXY, https_proxy, HTTP_PROXY or http_proxy.
  2. Use a global .tsdrc file and set a proxy value (see the tsdrc-section elsewhere in the readme).

The old TSD v0.3.0 had it's own repository data file that mapped module names to url's of definition files. This had a few downsides for (maintenance being one). Since v0.5.0 we link directly to DefinitelyTyped where the directory and file names are a reasonable indicator but not 100% identical to the names as you'd find them in npm, bower or other package managers.

The DefinitelyTyped group is working on a meta-data source that will solve this.

Yes, and no (and later yes again)

There is basic support for parsing semver-postfixes from the definition file names, and you can filter on this using semver ranges with the --version option: Try it with the 'node' definitions.

It works well but is not used much in the current DefinitelyTyped repository. The DefinitelyTyped group is working on a meta-data source that will solve this (the Nuget exporter is waiting for this too).

The cache is stored in the users home directory (like $ npm). Use $ tsd settings to view the current paths. Use the --cacheDir to override the cache directory, or --cacheMode to modify caching behaviour.

Feel free to leave a ticket. Questions and contributions for the definition files go here.

See the release tags fore more details.

  • 0.5.x - current - Full rewrite by @Bartvds: drops the separated TSD data registry in favour of using the Github API to pull definitions directly from DefinitelyTyped.

To install v0.3.x (old readme here):

$ npm install tsd@0.3.0 -g

Some essential modules used to build TSD:

TSD is build with TypeScript v0.9.7 and managed using Grunt.

To rebuild clone or fork the repos:

Install dependencies

$ npm install

Build, lint and test

$ grunt test

Only rebuild (and run cli)

$ grunt build

Either install global or use in dev folder:

Run in dev folder

$ node ./build/cli.js query d3 --dev

Install to global cli

$ npm install . -g

TSD uses gruntfile-gtx to test separate test suites sets during development:

List aliases

$ grunt -h

Example: run only api tests

$ grunt gtx:api
$ grunt gtx:cli
$ grunt gtx:tsd

It is recommend you use an intelligent parsing IDE (WebStorm or VisualStudio) and a big screen (or two) on a properly powerful workstation.

Code looks best with tabs rendered at 4 spaces (3 is nice too, or 6 or 8.. I don't really care, because smart-tabs are awesome like that). The gruntfile uses slightly harsh JSHint and TSLint settings to enforce code style, but there is an .editorconfig to elevate some of the pain.

Contributions are very welcome; please discuss larger changes in a ticket first. Fixes and simple enhancements are always much appreciated.

Note: Contributions on the definition files go directly to DefinitelyTyped.

The TSD CLI tool collects definition usage information, like the queries made to the repo and the definitions that get installed. The information collected amounts to about same level of detail as services like npm or github would collect (maybe even less as we don't track a user id).

The API does not track anything.

To store this TSD uses Google Analytics in the excellent universal-analytics package. We might at some point publish some anonymised aggregate stats to the DefinitelyTyped website.

The optional Github OAuth token is only used to authenticate with the Github API. The token is not stored anywhere but the local machine. It is your responsibility to keep your token safe.

Using an OAuth token with additional scope is not advised nor supported (even though it could make TSD work with private repositories). But it might also leak repo or content names to analytics or leave a bare http cache in your temp dir. If this bothers you please review the license and/or leave a message.

Changes to the policy should be announced in release notes, and ideally ask confirmation on the first CLI use.
