I am trying to package a bundle.js generated from my react app inside grails war. When I run it in the Intellij IDEA everything works fine. What I have is a npm-app which is a reactjs app which generates a bundle.js using webpack. When I include this bundle like below in my gsp pages it works fine when I run it in Intellij. But, when I package it using grails war, the war file generated does not show the app. The contents of the bundle.js were not included in the packaged War.

<div id="react-root"></div>
    <asset:javascript src="bundle.js"/>
</div>

Grails version: 3.3.8 Jdk: 1.8.0_432

This is my gradle.properties

grailsVersion=3.3.8
gormVersion=6.1.10.RELEASE
gradleWrapperVersion=3.5

I've tried to apply the options and asset plugins mentioned in this thread: Grails assets not work in deployed .WAR

Here's how my build.gradle looks like:

buildscript {
    repositories {
        mavenLocal()
        maven { url "; }

    }
    dependencies {
        classpath "org.grails:grails-gradle-plugin:$grailsVersion"
        classpath "org.grails.plugins:hibernate5:${gormVersion-".RELEASE"}"
        classpath "com.bertramlabs.plugins:asset-pipeline-gradle:2.14.8"
    }
}

version "0.1"
group "myapp"

apply plugin:"eclipse"
apply plugin:"idea"
apply plugin:"war"
apply plugin:"org.grails.grails-web"
apply plugin:"asset-pipeline"
apply plugin:"org.grails.grails-gsp"
apply plugin:"java"
apply plugin:"io.spring.dependency-management"

war.archiveName='myapp.war'

repositories {
    mavenLocal()
    maven { url "; }
}


dependencies {
    compile "org.springframework.boot:spring-boot-starter-logging"
    compile "org.springframework.boot:spring-boot-autoconfigure"
    compile "org.grails:grails-core"
    compile "org.springframework.boot:spring-boot-starter-actuator"
    compile "org.springframework.boot:spring-boot-starter-tomcat"
...
}

bootRun {
    jvmArgs('-Dspring.output.ansi.enabled=always')
    addResources = true
    String springProfilesActive = 'spring.profiles.active'
    systemProperty springProfilesActive, System.getProperty(springProfilesActive)
}


assets {
    minifyJs = true
    minifyCss = true
}

jar {
    manifest {
        attributes 'Main-Class': 'myapp.Application'
    }
}

war {
    manifest {
        attributes 'Main-Class': 'myapp.Application'
    }
}

Moreover, for the last section in the above build.gradle, when I was packaging it using Intellij the war was giving "no main manifest attribute" so I've already added the Main-class Attribute.

Can't execute jar- file: "no main manifest attribute"

Please advise how I can make it work he same way it is working inside Intellij. The reactjs app works fine if I run it independently as well so just to confirm that there is no issues with the reactjs app.

Update 2:

I tried to find out if this is because of reactjs minification and I tried excluding the minified files in Application.groovy, Application.yml. This didn't work:

grails.assets = [
        minifyJs: false,
        minifyCss: true,
        minifyOptions: [
                excludes: [
                        '**/jquery-2.2.0.min.js',  // Ensure correct path and extension
                        '**/bundle.js'
                ]
        ]
]

application.yml

grails:
    assets:
        minifyJs: true
        minifyCss: true
        minifyOptions:
            excludes:
                - '**/jquery-2.2.0.min.js'
                - '**/bundle.js'

I also tried adding this to application.js it still didn't work:

//= bundle.js

I tried a lot of approaches besides the ones mentioned above but nothing seem to work. Also considering I did not want the reactjs components to intrude with the grails javascript I did below workaround - hope this might help someone else stuck with similar situation.

I moved the compiled bundle.js into src/main/resources/ and created this ContentController to serve the file as raw javascript file:

@Controller
class ContentController extends RestfulController{
    def bundle(){
        def myBundleFileContents = getClass().getResource('/bundle.js').text
        response.setHeader("Content-disposition", "filename=bundle.js")
        response.contentType = 'text/javascript'
        response.outputStream << myBundleFileContents
        response.outputStream.flush()
    }
//more actions
}

Then I included the bundle file in my gsp page as below:

<script type="text/javascript" src="../content/bundle">
</script>
