Install Instructions

High Level Instructions

Uses Gradle node plugin to set up local to module node and npm

jsweet module requries a global node install

Gradle and the closure module need java on the path
see below for how to set up a temporary local java on windows

Windows with no java installed

Use the exe jre_installer.exe to extract the bundled java into
the directory java-windows then in a git bash terminal set the JAVA_HOME env
to point to this directory

export JAVA_HOME=~/transpilers-dev/java-windows

run the java commands with

` "$JAVA_HOME/bin"/java -version `  

Install top level node and npm debendencies

./gradlew install

the first time this downloads the gradle wrapper

Module Node Tasks

run `./gradlew tasks`  

`nodeSetup - Download and install a local node/npm version.`  
`npmInstall - Install node packages from package.json.`  
`npmSetup - Setup a specific version of npm to be used by the build.`  

Node amd npm example usage

Install node dependecies for closure module

./gradlew :closure:nodeSetup

Install npm dependencies for closure module

./gradlew :closure:npmInstall

react module

Run the dev server from the top level directory   

`./gradlew :react:runDevServer`

closure module

in the closure module transpiile the js source
`"$JAVA_HOME/bin"/java -jar compiler.jar --compilation_level=ADVANCED --closure_entry_point=dev.app --only_closure_dependencies  --js=./node_modules/google-closure-library --js src/main.js --js src/component.js --js_output_file  dist/app.min.js `

run the test  
"C:\Program Files (x86)/Mozilla Firefox"/firefox.exe Test.html

jsweet module

Linux

run as typical java gradle project
