Question

Sharing JavaScript code between Maven modules can be achieved by following these steps

My Maven project has a unique structure that includes:

"Base" module -- containing shared Java files -- should also include shared JavaScript files
Module 1 -- using shared Java files as a Maven dependency -- should utilize shared JavaScript files through ?
Module 2 -- utilizing shared Java files as a Maven dependency -- should incorporate shared JavaScript files using ?

Recently, I have noticed that webpack is gaining popularity in packaging JavaScript and npm serves as a reliable package manager. So, here's what I attempted: - The base module creates an npm bundle (using npm pack) with webpack - Modules 1 and 2 manually install this bundle by referencing the relative path to the target folder of the base module where the npm package resides

Why did I avoid using npm publish? - Updating published npm packages isn't feasible because it requires incrementing version numbers for each build - It necessitates an internet connection during the building process

Are there other options available? - One alternative I considered was employing the Maven resources plugin, but it seemed labor-intensive due to the manual aspects involved (such as file names, folder structures, etc.)

So my question is: How do you share JavaScript code among Maven modules within the same project? Is there a more efficient way to accomplish this task?

When it comes to redistributing npm modules individually, the recommended approach is to utilize the npm publish command. However, during the development phase, you can take advantage of the convenient feature provided by npm called npm link. This allows you to link your local folder as a global dependency, directing npm to use it instead of fetching from the repository. By incorporating the npm link command into your project and adjusting the node installation directory, all submodules will share the same node instance. This streamlined setup enables you to develop your modules seamlessly and proceed with publishing when you are prepared.

In the base/pom.xml file:

<plugin>
  <groupId>com.github.eirslett</groupId>
  <artifactId>frontend-maven-plugin</artifactId>
  ...
  <configuration>
    ...
    <installDirectory>../node</installDirectory>
  </configuration>
  <executions>
    <execution>
      <id>npm link</id>
      <goals>
        <goal>npm</goal>
      </goals>
      <configuration>
        <arguments>link</arguments>
      </configuration>
    </execution>
  </executions>
</plugin>

Within the module/pom.xml file:

<plugin>
  <groupId>com.github.eirslett</groupId>
  <artifactId>frontend-maven-plugin</artifactId>

  <configuration>
    <installDirectory>../node</installDirectory>
  </configuration>
  <executions>
    <execution>
      <!-- linking prior to installation -->
      <id>npm link softvis3d-viewer</id>
      <goals>
        <goal>npm</goal>
      </goals>
      <configuration>
        <arguments>link softvis3d-viewer</arguments>
      </configuration>
    </execution>
    <execution>
      <id>npm install</id>
      <goals>
        <goal>npm</goal>
      </goals>
    </execution>
    ...
  </executions>
</plugin>

And in the module/package.json file:

  "devDependencies": {
    ...
    "softvis3d-viewer": "0.0.4-SNAPSHOT"
  },

If you're looking to make use of NPM within a Maven module for JavaScript transpiling, minification, and concatenation, there are some key considerations to keep in mind. Utilizing web-fragment.xml as specified in the Servlet 3.0 specs can help in sharing pre-compiled modules by placing JavaScript files under META-INF/resources. Depending on your front end tech stack, strategies like code splitting or leveraging web components may be necessary.

It's important for the client-side to load and execute library code before any dependent functionalities are accessed.

For sharing specific APIs across Maven modules within the same eco-system with npm, options like 'npm publish' and 'npm link' can prove useful. However, for larger pieces of functionality that aren't always used, dynamic loading may be more appropriate.

While the concepts of POMs, JARs, NPMs, and JS/ES6 modules are not new, the community is still exploring the most effective approaches. Finding a clean, comprehensive set of rules and configurations to handle these technologies seamlessly is an ongoing process.
