sbt-typescript
Allows TypeScript to be used from within sbt. Leverages the functionality of com.typesafe.sbt:js-engine to run the typescript compiler.
To use this plugin use the addSbtPlugin command within your project's plugins.sbt (or as a global setting) i.e.:
addSbtPlugin("com.arpnetworking" % "sbt-typescript" % "0.1.10")You will also need to enable the SbtWeb plugin in your project.
The options provided mimic the arguments to the tsc command line compiler.
| Option | Description |
|---|---|
| declaration | Generates corresponding '.d.ts' file. |
| sourceMap | Generates source maps for input files. |
| sourceRoot | Specifies the location where the compiler should locate TypeScript files instead of the source locations. |
| mapRoot | Specifies the location where the compiler should locate map files instead of generated locations. |
| target | ECMA script target version. Should be "ES3" or "ES5" (default). |
| noImplicitAny | Warn on expressions and declarations with an implied "any" type. |
| moduleKind | Specifies module code generation. Should be "" (default), "commonjs", or "amd". |
| outFile | Concatenate and emit output to a single file. |
| outDir | Destination directory for output files. |
| removeComments | Removes comments from the generated source. |
| jsx | Specifices JSX-mode for .tsx files. Should be "preserve" (default) to generate .jsx or "react" to generate .js files. |
By default, all typescript files (*.ts and *.tsx) are included in the compilation and will generate corresponding javascript files. To change this, supply an includeFilter in the TypescriptKeys.typescript task configuration.
For example:
includeFilter in TypescriptKeys.typescript := "myFile.ts"You can also set an exclude filter in the same way.
A note on typescript compiling speed
Sometimes the default engine (Trireme) can be quite slow. If you're experiencing long typescript compile times you can always switch to node.js (remember to install it first) adding this line to your build.sbt file:
JsEngineKeys.engineType := JsEngineKeys.EngineType.Node© Groupon Inc., 2014
