如何在同一项目中为Gulp和RequireJS使用打字稿定义？

Question

I have a Visual Studio 2015 ASP.Net Core project which uses Gulp and RequireJS. Gulp is used at compile-time, and RequireJS is used at run-time.

The typescript definitions for Gulp include the definitions for node, and this causes a definition collision with RequireJS:

TS2403 Build:Subsequent variable declarations must have the same type. Variable 'require' must be of type 'NodeRequire', but here has type 'Require'.

Is there a way to work around this?

Manually Editing the Definitions

I don't want to manually edit the definition files as that would create maintenance problems compared to just getting them directly from NPM.

Also it wouldn't fully solve the problem as require would have the wrong type in one of the situations depending on which I commented out.

Relevant SO Questions

I found this question: Unable to use requireJS and Node's Require in the same TypeScript project .

It has an answer suggesting using CommonJS everywhere, but as I don't own the Gulp or RequireJS typings I can't change that.

Answer 1

Hopefully you're using two tsconfig.jsons, one for compile-time concerns and one for run-time concerns. With two configs you can explicitly choose which types to apply to each target with the types compiler option.
