dts-critic
Checks a new dts against the Javascript sources and tells you what problems it has.
Usage
Build the program:
$ npm run build
Run the program using node:
$ node dist/index.js --dts=path-to-d.ts [--js=path-to-source] [--mode=mode] [--debug]
If the d.ts path is to a file named index.d.ts
, the name of the directory
will be used as the package name instead. For example
~/dt/types/jquery/index.d.ts
will use jquery
as the name.
path-to-source
is optional; if you leave it off, the code will
check npm for a package with the same name as the d.ts.
Mode
You can run dts-critic in different modes that affect which checks will be performed:
name-only
: dts-critic will check your package name and DefinitelyTyped header (if present) against npm packages. For example, if your declaration is for an npm package called 'cool-js-package', it will check if a package named 'cool-js-package' actually exists in npm.code
: in addition to the checks performed inname-only
mode, dts-critic will check if your declaration exports match the source JavaScript module exports. For example, if your declaration has a default export, it will check if the JavaScript module also has a default export.
Current checks
Npm declaration
If your declaration is for an npm package:
- An npm package with the same name of your declaration's package must exist.
- If your package has a Definitely Typed-conforming package.json, the npm package's version must match your version.
- If you are running under
code
mode, your declaration must also match the source JavaScript module.
Non-npm declaration
If your declaration is for a non-npm package (in other words, if your declaration has a
Definitely Typed-conforming package.json with "nonNpm": true
):
- An npm package with the same name of your declaration's package cannot exist.
- If you are running under
code
mode and a path to the JavaScript source file was provided, your declaration must also match the source JavaScript module.
Planned work
- Make sure your module structure fits the source.
- Make sure your exported symbols match the source.
- Make sure your types match the source types???
- Download source based on npm homepage (if it is github).
Note that for real use on Definitely Typed, a lot of these checks need to be pretty loose.

Testing
The tests use the Jest framework. To build and execute the tests, run:
$ npm run test
This will build the program and run jest.
