TypeScript definition file for SPServices

Question

I am wondering if anyone knows if there is a TypeScript definition file for the SPServices JS library? I have found a .d.ts file in the GitHub repo but it does not appear to be complete. I have also search (with no luck except this definition request) through what is available on Definitely Typed. If none exists, does anyone know of a good reference for information about how to create definitions from the JS code?

Answer 1

I didn't find the definition you need. However, you can visit

http://definitelytyped.org/

and read guides for contributing or this quick introduction.

Summary:

• Essentially, it is necessary to create a .d.ts file which is then referenced by the special comment /// <reference path="../path/to/file.d.ts" /> in your TypeScript script.
• Content of .d.ts files is typically written by hand. lib.d.ts was generated by a script but it is an exception. You can check some projects that try to generate definition files.

• A complete example of a definition file (amplifyjs.d.ts):
