i am getting an error from createVue3SFCModule.ts:305.
Uncaught (in promise) TypeError: Unable to handle .png files (images/logo.png)

Is there a workaround to bringing images in?

in the component:
[img src="../images/logo.png"] (replace [] with angles)
also tried:
import logo from "../images/logo.png";

the following is the config:

const options = {
  moduleCache: {
    vue: Vue,
  },
  async getFile(url) {
    const res = await fetch(url);
    if (!res.ok)
      throw Object.assign(new Error(url + " " + res.statusText), { res });
    return await res.text();
  },
  addStyle(textContent) {
    const style = Object.assign(document.createElement("style"), {
      textContent,
    });
    const ref = document.head.getElementsByTagName("style")[0] || null;
    document.head.insertBefore(style, ref);
  },
};
const { loadModule } = window["vue3-sfc-loader"];
const app = Vue.createApp({
  components: {
    vLayout: Vue.defineAsyncComponent(() =>
      loadModule("components/vLayout.vue", options)
    ),
  },
  template: "<vLayout></vLayout>",
});
app.mount("#app");

edit: using vs-code and live-server. i saw one github issue with live-serve sending incorrect mime types, so can't be certain it is sfc-loader.

Hi everyone,
still have problems with PNG files in the vue component - can somebody help me? :-) Thx in advance
Uncaught (in promise) TypeError: Unable to handle .png files (public/assets/img/gallery/student-feedback.png)

here's my code

extract of index.html

<!DOCTYPE html>
<html class="h-100">
<head>
<script src="https://cdn.jsdelivr.net/npm/vue@3"></script>  
<script src="https://cdn.jsdelivr.net/npm/vue3-sfc-loader@0.8.4/dist/vue3-sfc-loader.min.js"></script>
...
</head>
<body>
....
<div id="app"></app>
....
<script>

const { loadModule } = window['vue3-sfc-loader'];

      const options = {
        moduleCache: {
          vue: Vue
        },
        async getFile(url) {
          
          const res = await fetch(url);
          if ( !res.ok )
            throw Object.assign(new Error(res.statusText + ' ' + url), { res });
          return {
            getContentData: (asBinary) => asBinary ? res.arrayBuffer() : res.text(),
          }
        },
        addStyle(textContent) {
  
          const style = Object.assign(document.createElement('style'), { textContent });
          const ref = document.head.getElementsByTagName('style')[0] || null;
          document.head.insertBefore(style, ref);
        }
      }
      const Club = Vue.defineAsyncComponent( () => loadModule('./Club.vue', options) )

     .... some vue-router stuff here ....

     const app = Vue.createApp({ });
      
      app.mount('#app');

</script>
</body>

Club.vue

<template>
     <img class="w-100" src="./public/assets/img/gallery/student-feedback.png" alt="..." /> 
</template>

<script>
    export default {

    }
</script>

I don't know if any of this is still maintained, but as of Jan 5th 2024, that bug is still present, or the solution is still NOT clear from the circling "See #69"=>"See #60".

So i'll write my easy work around the problem :

I have a logo component :

Logo.vue

<template>
     <img class="w-100" :src="srcLogo" alt="Logo" /> 
</template>

<script>
    data() {
    return {
      srcLogo: undefined,
    };
  },
  methods: {
    changeSource: function () {
      this.srcLogo = "./public/assets/img/gallery/logo.png";
    },
  },
  mounted() {
    this.changeSource();
    console.log('Vue logo mounted');
  }
</script>

Basically changes the img src once the tag has been created in the dom, so vue-sfc-loader doesn't think it's loading a file (I think, idc, it works without error messages now)

I've just added an example of image loading:
