How to encode image to base64 in q-uploader?

[nomad]

I’m just starting to learn Quasar (and Vue). I’m trying to encode a picture into a Base64 and save to MongoDB.
Undermentioned code works for the component <inpute> but I can’t redo it for the component <q-uploader>.
I will be thankful for any help

 <q-uploader v-model="image" @change="encodeToBase64" />
 <q-btn type="btn" @click="sendPhoto">Save photo in mongo and go next page</q-btn>

methods: {
    encodeToBase64 (event) {
      event.preventDefault()
      const file = event.target.files[0]
      const canvas = document.createElement('canvas')
      const ctx = canvas.getContext('2d')
      const reader = new FileReader()
      reader.onload = event => {
        const img = new Image()
        img.onload = () => {
          if (img.width > MAX_WIDTH) {
            canvas.width = MAX_WIDTH
            canvas.height = (MAX_WIDTH * img.height) / img.width
          } else {
            canvas.width = img.width
            canvas.height = img.height
          }
          ctx.drawImage(img, 0, 0, canvas.width, canvas.height)
          this.image = canvas.toDataURL('image/png').replace(/^data:image\/(png|jpg);base64,/, '')
          console.log('RESULT/png', this.image)
        }
        img.src = event.target.result
        console.log('RESULT!', img.src)
      }
      reader.readAsDataURL(file)
    }
}

  sendPhoto (event) {
      event.preventDefault()
      this.$store.dispatch('image/create', {account_id: this.account_selected, image: this.image})
        .then((res) => {
          this.$router.push({'path': '/nextReadings/' + res._id})
        })
        .catch((err) => {
          err.message = 'Error message'
          this.errorHandler(err.message)
        })
    }

@nomad you can use factory props https://v1.quasar-framework.org/vue-components/uploader#Example--Promise-based-factory-function or convert the file to base64 in your consuming api before inserting it in your mongodb (this is probably better). what you posted above though is best suited for a customized input component w/ type of file, as q-uploader has its own api.

here’s a mock test converting base64 in client side using factory prop of q-uploader https://codepen.io/metalsadman/pen/YMvEbr?editors=1011 check browser console for the converted base64 data.
