Tracking file upload progress using axios

upload.js

upload(files) {
  const config = {
    onUploadProgress: function(progressEvent) {
      var percentCompleted = Math.round((progressEvent.loaded * 100) / progressEvent.total)
      console.log(percentCompleted)
    }
  }

  let data = new FormData()
  data.append('file', files[0])

  axios.put('/endpoint/url', data, config)
    .then(res => console.log(res))
    .catch(err => console.log(err))
}

You are champ.

Thanks

Thanks

Thank you ♥

Very useful,have a wonderful day!

Thanks you 🚀

Thanks a bunch! Clean & nice code

Спасибо!

With some improvements:

const onUploadProgress = event => {
    const percentCompleted = Math.round((event.loaded * 100) / event.total);
    console.log('onUploadProgress', percentCompleted);
};

const upload = async files => {
    const data = new FormData();
    
    for(const [index, file] of files.entries()){
        data.append(index, file); // append all files
    }

    try {

        const result = await axios.put('/endpoint/url', data, {onUploadProgress});

        console.log('result is', result); // result is server's response

    } catch(error){
        console.error(error);
    } finally {
        console.log('Upload complete');
    }
}
