TypeScript Gradle Plugin

This plugin makes it easy to build TypeScript projects using Gradle. Among other things, the plugin provides a task to run the TypeScript compiler.


This will guide you through the steps needed to set up typescript-gradle-plugin for a TypeScript application project using Maven/Gradle standard layout.
You can either use this plugin in combination with the Gradle Node plugin (recommended) or alternatively use it standalone with a local Node and TypeScript installation.

Usage with Node plugin

This is the recommended way to use the TypeScript Gradle plugin. Using the Node plugin has the advantage that you do not need to have Node or TypeScript installed manually on the system to execute the TypeScript compile task. You can define a TypeScript compiler version which gets downloaded automatically.

Add plugin dependencies

Add a plugin dependency for the Node plugin and for the TypeScript Gradle plugin.

If you are using Gradle 2.1 or later, define the plugin dependency as follows:

plugins {
  id "com.moowork.node" version "0.12"
  id "de.richsource.gradle.plugins.typescript" version "1.8.0"

If you are using Gradle 2.0 or earlier, define the plugin dependency as follows:

buildscript {
  repositories {
    maven {
      url ""
  dependencies {
    classpath "com.moowork.gradle:gradle-node-plugin:0.12"
    classpath "de.richsource.gradle.plugins:typescript-gradle-plugin:1.8.0"

apply plugin: 'com.moowork.node'
apply plugin: 'de.richsource.gradle.plugins.typescript'

Configure the TypeScript task to use the Node executable

Configure the TypeScript task to use the Node executable as follows:

import com.moowork.gradle.node.NodeExtension
import com.moowork.gradle.node.variant.VariantBuilder

node {
  download = true

String nodeExecutable() {
  NodeExtension nodeExt = NodeExtension.get(project)
  return new VariantBuilder(nodeExt).build().nodeExec

compileTypeScript {
  compilerExecutable "${nodeExecutable()} node_modules/typescript/lib/tsc.js"
  dependsOn "npmInstall"

Create package.json with TypeScript version

Create a package.json file next to the build.gradle file and declare the TypeScript compiler version to use as follows:

{ "dependencies": { "typescript": "1.8.7" } }

Usage with local Node and TypeScript installation

This is not the recommended way of using the plugin. You should prefer to use it with the Node plugin. But if you have good reasons to do so, here is how...

You need to have installed node.js and installed the typescript node module:

npm install -g typescript

Alternatively on windows you can install the Typescript SDK and configure the compilerExecutable config option to tsc - see Available configuration options.

Add plugin dependency

If you are using Gradle 2.1 or later, define the plugin dependency as follows:

plugins {
  id "de.richsource.gradle.plugins.typescript" version "1.8.0"

If you are using Gradle 2.0 or earlier, define the plugin dependency as follows:

buildscript {
  repositories {
    maven {
      url ""
  dependencies {
    classpath "de.richsource.gradle.plugins:typescript-gradle-plugin:1.8.0"

apply plugin: "de.richsource.gradle.plugins.typescript"

Configuring the TypeScript compile task

You can configure the TypeScript compile task as shown below:

compileTypeScript {
	sourcemap = true
	// additional configuration options

Run the TypeScript compiler

gradle compileTypeScript

Available configuration options

Here is a list of the available configuration options of the compileTypeScript task:

Option Type Description
source File directories to compile, defaults to src/main/ts
outputDir File the output directory, defaults to buildDir/ts
out File DEPRECATED. Use outFile instead.
outFile File Concatenate and emit output to single file, e.g. file("${buildDir}/js/out.js"). The order of concatenation is determined by the list of files passed to the compiler on the command line along with triple-slash references and imports. See output file order documentation for more details.
module Module Specify module code generation (AMD, COMMONJS, SYSTEM, UMD, ES6 or ES2015)
target Target Specify ECMAScript target version (ES3, ES5, ES6 or ES2015)
declaration boolean Generates corresponding .d.ts file
noImplicitAny boolean Warn on expressions and declarations with an implied 'any' type
noResolve boolean Skip resolution and preprocessing
removeComments boolean Do not emit comments to output
sourcemap boolean Generates corresponding .map file
sourceRoot File Specifies the location where debugger should locate TypeScript files instead of source locations
codepage Integer Specify the codepage to use when opening source files
mapRoot File Specifies the location where debugger should locate map files instead of generated locations
compilerExecutable String The tsc compiler executable to use. Defaults to cmd /c tsc.cmd on windows and tsc on other systems.
noEmitOnError boolean Do not emit outputs if any type checking errors were reported
noEmit boolean Do not emit outputs
experimentalDecorators boolean Enables experimental support for ES7 decorators
newline Newline Specifies the end of line sequence to be used when emitting files (CRLF or LF)
preserveConstEnums boolean Do not erase const enum declarations in generated code
projectFile File Compile the project using the given tsconfig file, or - if a directory is specified - compile the project in the given directory where a tsconfig.json file is present. File specified with the source option will be ignore, but you should still explicitly configure the source files as this will make the Gradle UP-TO-DATE check work.
rootDir File Specifies the root directory of input files. Use to control the output directory structure with outDir.
suppressImplicitAnyIndexErrors boolean Suppress noImplicitAny errors for indexing objects lacking index signatures
noEmitHelpers boolean Do not emit helpers like __extends
inlineSourceMap boolean Causes source map files to be written inline in the generated .js files instead of in a independent file
inlineSources boolean Allows for additionally inlining the source .ts file into the .js file when used in combination with inlineSourceMap
watch boolean Watch input files
charset String The character set of the input files
emitBOM boolean Emit a UTF-8 Byte Order Mark (BOM) in the beginning of output files
emitDecoratorMetadata boolean Emit design-type metadata for decorated declarations in source
isolatedModules boolean Unconditionally emit imports for unresolved files
jsx Jsx Specify JSX code generation (PRESERVE or REACT)
locale String The locale to use to show error messages, e.g. en-us
moduleResolution ModuleResoltion Specify module resolution strategy (NODE or CLASSIC)
noLib boolean Do not include the default library file (lib.d.ts)
stripInternal boolean Do not emit declarations for code that has an /** @internal */ JSDoc annotation
diagnostics boolean Show diagnostic information.
reactNamespace String Specifies the object invoked for createElement and __spread when targeting 'react' JSX emit.
listFiles boolean Print names of files part of the compilation.
pretty boolean Stylize errors and messages using color and context.
suppressExcessPropertyErrors boolean Suppress excess property checks for object literals
allowUnusedLabels boolean Do not report errors on unused labels
noImplicitReturns boolean Report error when not all code paths in function return a value
noFallthroughCasesInSwitch boolean Report errors for fallthrough cases in switch statement
allowUnreachableCode boolean Do not report errors on unreachable code
forceConsistentCasingInFileNames boolean Disallow inconsistently-cased references to the same file
allowSyntheticDefaultImports boolean Allow default imports from modules with no default export. This does not affect code emit, just typechecking.
allowJs boolean Allow JavaScript files to be compiled
noImplicitUseStrict boolean Do not emit "use strict" directives in module output


Several example projects can be found in /examples.

Integrating the compiled files into a WAR file (for Java Webapps)

If you are integrating TypeScript into a Java web application, you can easily integrate the compiled files into the WAR file. All you have to do is to configure the war task to pick up the compiled files. Whenever you call the war task, the TypeScript compiler will compile your TypeScript files first. In the example below, the compiled files will be put into the js directory in the WAR file.

apply plugin: "war"

war {
		into("js") {
    		from compileTypeScript.outputs

Configuring multiple source directories

You can configure the TypeScript compile task to use multiple source directories as shown below:

compileTypeScript {
	source = [file("src/main/ts"), file("src/main/additionalts")]
