Why does Typescript compiler not change .ts to .js?

由 徘徊边缘 提交于 2019-12-07 08:34:14
问题 In the image below on the left in the folders you can see my /src Typescript (blue) compiled into my /dist (purple) Javascript using tsc. You can see in the source file on the left that references a .ts module file that it isn't compiled into referencing a .js module file on the right. Why not? How could the Javascript possibly run if tsc doesn't convert references? Second question: I then tried manually changing the compiled reference from .ts to .js and running node dist/server.js but I get

问题 So I have a unit test written for mocha using TypeScript. I am trying to run it using gulp (which doesn't really play a part here).

Run TypeScript compiler from Java

由 ≡放荡痞女 提交于 2019-12-06 05:48:45
问题 I am trying to run the TypeScript compiler from my Java application. To start, I am trying to figure out, whether I can run the compiler from command-line without Node.js: $ jsc tsc.js But this way I don't get any errors, nor help. $ jsc tsc.js myscript.ts Will get me nowhere. It is easy to run js code directly from java (and I am hoping to run the compiler in this way), but is it possible to run TypeScript compiler without node.js? EDIT: I confirm the same behaviour with rhino. 回答1: Looking

WebPack ts-loader compiling all files when I only want it to run in one folder/file

由 戏子无情 提交于 2019-12-06 02:23:53
问题 I found a problem in my app structure and build process using WebPack, TypeScript, and TS-Loader that I thought was caused by TypeScript 2.1.4, but apparently was there the whole time. You can see all the details from my other post: TypeScript 2.1.4 breaking changes in webpack ts-loader In short, I have Gulp and WebPack set to an entry point of /client/app.ts which for now has almost nothing in it (certainly nothing referencing /server/) but the TypeScript compilation stage of the WebPack
