Learn how to effortlessly integrate and utilize a bpmn file in a Vue component by leveraging the raw-loader

As a newcomer to bpmn-js, I am facing the challenge of importing and utilizing a .bpmn file within a vue.js component (BPMNViewer.vue). Despite my efforts in researching, I could only find recommendations to use the raw-loader. Consequently, I am currently stuck at this point.

<script>
import demo from './examples/demo.bpmn'
...

export default {
  data() {
    return {
      xmlData: demo,
    };
  }
}

The above code snippet leads to the following Error message:

error in ./src/views/BPMNViewer.vue?vue&type=script&lang=js&

Module not found: Error: Can't resolve './examples/demo.bpmn' in '/bpmn-test/src/views'

ERROR in ./src/views/BPMNViewer.vue?vue&type=script&lang=js& (./node_modules/@vue/vue-loader-v15/lib/index.js??vue-loader-options!./src/views/BPMNViewer.vue?vue&type=script&lang=js&) 12:0-39

 @ ./src/main.js 3:0-29 9:2-8
webpack compiled with 1 error

I have attempted to include the raw-loader in my vue.config.js as follows:

const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
    transpileDependencies: true,

    chainWebpack: config => {
        config.module
            .rule("bpmn")
            .test(/\.bpmn$/)
            .use("raw-loader")
            .loader("raw-loader")
            .end();
    }
})

This is an excerpt from my package.json:

{
  "name": "bpmn-test",
  "version": "0.1.0",
  "private": true,
  ...
 

It seems like there might be something missing in the setup. Any guidance or further information required would be highly appreciated.

This doesn't seem to be specific to Bpmn-js. Before proceeding, make sure that the raw XML is present in your xmlData object.

It's possible that your webpack configuration is not set up to utilize the raw-loader for files with the .bpmn extension. One way to address this is by using an inline solution:

import demo from 'raw-loader!./examples/demo.bpmn'

(If you haven't installed the raw-loader yet: npm install raw-loader --save-dev)
