Let’s deploy an angular application on a wildfly server. Let’s get started.

1. We need an angular application so let’s run

$ npm install --global @angular/cli

# if installation finished

$ ng new my-awesome-application

2. Lets create a maven pom.xml in root folder of the project

<project xmlns="http://maven.apache.org/POM/4.0.0"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">




3. Let’s create some folders and files for the wildfly server

# call from project root folder
$ mkdir -p src/main/webapp/WEB-INF

# a jboss web xml required if you want to specify the context-root of the application
$ touch src/main/webapp/WEB-INF/jboss-web.xml 

# just to setup the welcome file
$ touch src/main/webapp/WEB-INF/web.xml

# html5 mode magic
$ touch src/main/webapp/WEB-INF/undertow-handlers.conf

4. set context-root in jboss-web.xml

(optional step - context-root will be set to ${project.artifactId}-${project.version} if not specified)

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"


5. setup web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"



remember the defined location /resources (it means -> src/main/webapp/resources)

6. setup undertow-handlers.conf

path-prefix('/api') -> done
path-suffix('.js') -> done
path-prefix('/') -> rewrite('/')
  1. first prefix is only required if you want use a custom backend in your application (not angular) e.g. jax-rs
  2. if you have other files (css, fonts, etc) you have to add more rules like the second e.g. path-suffix(‘.etc’) -> done
  3. the third line is our catch all handler to route all other matching routes to our welcome file (it makes HTML5 Mode possible)

7. update angular.json

u have to add 2 more properties and update 1 property under: projects > my-awesome-application > architect > build > options

  • update - outputPath - should point to src/main/webapp/resources HINT: THIS FOLDER WILL BE CLEARED FOR EVERY ANGULAR BUILD
  • add - baseHref - this must be the context root of your application, e.g.:
    • if jboss-web.xml is like step 4 "baseHref": "/my-aweosome-application/"
    • if no context root is specified "baseHref": "/${project.artifactId}-${project.version}/" e.g. "baseHref": "/${my-awesome-application}-${1.0-SNAPSHOT}/"
  • add - deployUrl - this must be the relative path from context-root to the resources folder - its required for source linking - our outputPath ends up in the resources folder - deployUrl have to be "deployUrl": "resources/" HINT: Path separator suffix is required…

here an example

  // ...
  "projects": {
    "my-awesome-application": {
      // ...
      "architect": {
        "build": {
          // ...
          "options": {
            "outputPath": "dist",
            "baseHref": "/my-awesome-application/",
            "deployUrl": "resources/",
            // ...
          }, // ...
        }, // ...
      }, // ...
    }, // ...
  }, // ...
}, // ...
