Describe the bug

I am trying to make a DIV be a FilePond Element. I followed the in the documentation with the following code:

    handleFilePondInit: function() {
      console.log('FilePond has initialized')

      // example of instance method call on pond reference
      let pondDiv = this.$el.querySelector('#ctFilePond1a')
      this.$refs.ctPond.appendTo(pondDiv)
    },

                <div
                  id="ctFilePond1a"
                  ref="ctFilePond1a"
                  class="filepond--root mt-1 border-2 bg-red-300 border-gray-300 border-dashed rounded-md px-6 pt-5 pb-6 flex justify-center "
                  @dragover.prevent
                  @drop.prevent
                >
                  <div class="space-y-1 text-center">
                    <svg
                      class="mx-auto h-12 w-12 text-gray-400"
                      stroke="currentColor"
                      fill="none"
                      viewBox="0 0 48 48"
                      aria-hidden="true"
                    >

                        stroke-linecap="round"
                        stroke-linejoin="round"
                      />
                    </svg>

                    <span>Upload a file </span>
                    <FilePond
                      id="ctFilePond1a"
                      ref="ctPond"
                      name="ctUploads"
                      accepted-file-types="*"
                      label-idle=""
                      allow-multiple="true"
                      instant-upload="false"
                      :files="ctFiles"
                      @init="handleFilePondInit"
                      @updatefiles="handleUpdateFiles"
                    />

                    <p class="text-xs text-gray-500">
                      PNG, JPG, GIF up to 15MB
                    </p>
                  </div>
                </div>

The error I get is: TypeError: this.$refs.ctPond.appendTo is not a function. (In 'this.$refs.ctPond.appendTo(pondDiv)', 'this.$refs.ctPond.appendTo' is undefined)

<style scoped lang="postcss">
:deep(.filepond--panel-root) {

}

:deep(.filepond--drop-label) {
  background-color: indianred;
}
</style>

The goal is to make the light red area the drop zone, not just the dark red (what is the current Vue-FilePond object).

If you want to use FilePond like this (append it to another element) then I'd advise not to use the Vue FilePond wrapper but instead use the core library.

Alternatively you can adjust the FilePond styles to enlarge the drop area.

Answer 2 · 2021-12-21T15:23:38.000Z

Is there a list of which methods are available on Vue-FilePond vs those that are not?

There is not, for the most part you should not use the functions that interact with the DOM, that's what the components are for.
