The Vue application encountered an issue while trying to mount the component due to the absence of a defined template or render function. The error was triggered

Here is the code snippet for my component:

<template>
            <uploader class="uploader-example">
                <uploader-unsupport></uploader-unsupport>
                <uploader-drop>
                    <p>Drop files here to upload or</p>
                    <uploader-btn>select files</uploader-btn>
                    <uploader-btn :directory="true">select folder</uploader-btn>
                </uploader-drop>
                <uploader-list></uploader-list>
            </uploader>

</template>

<script lang="ts">
    import { Component, Vue } from 'vue-property-decorator';
    import uploader from 'vue-simple-uploader';
    @Component({
        components: {
            Uploader: uploader,
        },
    })
    export default class In extends Vue {

    }
</script>

This is how my shims-vue.d.ts file is structured:

declare module '*.vue' {
  import Vue from 'vue';
  export default Vue;
}

declare module 'vue-simple-uploader';

After implementing the above code, I encountered the following error:

[Vue warn]: Failed to mount component: template or render function not defined.

In addition, the uploader component is not being rendered as expected.

I utilized the package available at:

https://github.com/simple-uploader/vue-uploader

Answer №1

Make sure to correctly bind the library - it should be used as a Vue plugin, not as an independent component.

Refer to the project's readme for the proper usage:

// main.ts
import Vue from 'vue'
import uploader from 'vue-simple-uploader'

Vue.use(uploader)

There is no need for additional imports as it is globally registered. While this isn't recommended practice, that is how the component has been designed.

Answer №2

Don't forget to initialize the uploader in your main app.js file:

import Vue from 'vue'
import uploader from 'vue-simple-uploader'
import App from './App.vue'

Vue.use(uploader)

Alternatively, you can try this approach:

@Component({
    components: {
        uploader: uploader,
    },
})
