Typescript – Generate one declaration file for TypeScript library

declarationtsctypescript

I developed a library, which also contains TypeScript files, in Visual Studio 2013. The files are compiling correctly to JS files (AMD).

What I want is to create a single declaration file for this lib, but this does not work:

tsc --declaration --module AMD --out out.d.ts [files.ts]

Can someone please lead me to the right path?

TypeScript 0.9.1.1 is used.

Best Solution

Its because you are providing .d.ts to out which will overwrite the declaration file with js contents. Also, you need to remove module amd because that works on per file basis (not --out friendly, see http://www.youtube.com/watch?v=KDrWLMUY0R0&hd=1)

So, try:

tsc [files.ts] --declaration --out out.js

which will generate out.d.ts

Typescript – Could not find a declaration file for module ‘module-name’. ‘/path/to/module-name.js’ implicitly has an ‘any’ type

Here are two other solutions

When a module is not yours - try to install types from @types:

npm install -D @types/module-name

If the above install errors - try changing import statements to require:

// import * as yourModuleName from 'module-name';
const yourModuleName = require('module-name');

The actual solution is given in a comment by @Paleo in @hirikarate's answer:

Imports should be declared inside the module declaration.

Example:

declare module 'node-helper-lib' {
   import * as SomeThirdParty from 'node-helper-lib';
   interface Helper {
       new(opt: SomeThirdParty.Options): SomeThirdParty.Type
   }
   export = Helper;
}
