<p dir="auto">In fact, I just begin to learn typescript, because the angular2.0, I use the <code class="notranslate">https://github.com/angular/quickstart</code> as the begining, and I change it's file structure, add ts folder, and move the typescript file to ts folder, change npm scripts:</p>
<p dir="auto"><code class="notranslate">"start": "tsc &amp;&amp; concurrently \"tsc -w\" \"lite-server\" ",</code>   ----&gt;<br>
<code class="notranslate">"start": "npm run build:css &amp;&amp; tsc --outDir ./app/scripts/ --rootDir ./app/ts/ &amp;&amp; concurrently \"npm run tsc:w\" \"lite-server\" ",</code></p>
<p dir="auto"><code class="notranslate">"tsc:w": "tsc -w",</code> ----&gt;<br>
<code class="notranslate">"tsc:w": "tsc -w --outDir ./app/scripts/ --rootDir ./app/ts/",</code></p>
<p dir="auto">I start the project by run npm start, the tsc generate related js file to app/scripts folder, but when I change some typescirpt file, instead of outputing to the --outDir folder, it outputs .js files to where the .ts file is. It just happens after changing the file, the first compilation is right.</p>
