How to configure Visual Studio to combine all TypeScript files into one JavaScript file?

Question

Using tsc command it's as easy as running:

tsc --out all.js js/*.ts

How can I configure Visual Studio to do that when I build my project?

Answer 1

I've found a potentially easier solution by just modifying the build properties of the project (.csproj / .vbproj) you are building:

I'm unsure which version of Typescript that this feature was introduced in. But it seems a much simpler method than the svallory's solution

EDIT: Since Visual Studio 2015, it's now very easy to integrate Grunt/Gulp tasks and have them run in your builds. I've personally be really enjoying using Gulp for more granular control over what files I build and/or minify, and I highly recommend it. Using this guide as a starting point should help.

Just got it. Add this line:

<Exec Command="tsc --out all.js @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />

to the BeforeBuild target of your .csproj or .vbproj file, like this:

<Target Name="BeforeBuild">
    <Message Text="Compiling TypeScript files" />
    <Message Text="Executing tsc$(TypeScriptSourceMap) @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
    <Exec Command="tsc$(TypeScriptSourceMap) @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
    <Exec Command="tsc --out all.js @(TypeScriptCompile ->'&quot;%(fullpath)&quot;', ' ')" />
</Target>
