VisualizaçõesHow to make javascript image blob object in react native?
I have to make an image blob object like this :
Now I can get the image base64 url in react native which I store in a variable :
const base64 = img.data;
I've tried this way but didn't work :
function b64toBlob(dataURI) {
var byteString = atob(dataURI.split(',')[1]);
var ab = new ArrayBuffer(byteString.length);
var ia = new Uint8Array(ab);
for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}
return new Blob([ab], {type: 'image/jpeg'});
}
const blob = b64toBlob(base64);
console.log(blob);
const base64 = img.data;
Now How can I create a blob object just like the image above with this base64 variable in react native ?

I solved the issue this way :
ImagePicker.openPicker({
width: 400,
height: 400,
cropping: true,
includeBase64: true,
})
.then(image => {
setImg(image);
})
.then(() => setModalVisible(prev => !prev));
const image = {
name: nn,
uri: img.path,
type: img.mime,
size: img.size,
lastModifiedDate: JSON.parse(img.modificationDate),
uid: img.modificationDate,
};
const form = new FormData();
form.append('file', image);
axios
.post('url', form, {
headers: {
Authorization: `bearer ${JSON.parse(token)}`,
},
})
