I was previously using ApiSauce to post listings from React Native App to Node.js with Multer, and now I have migrated to Axios everything went fine except for the uploading images part.
export const add = (listing, onUploadProgress) => {
const data = new FormData();
data.append('title', listing.title);
data.append('price', listing.price);
data.append('categoryId', listing.category.value);
data.append('description', listing.description);
data.append('userId', listing.userId);
listing.images.forEach((image, index) =>
    data.append('images', {
        name: 'image' + index,
        type: 'image/jpeg',
        uri: image,
    }),
);
if (listing.location)
    data.append('location', JSON.stringify(listing.location));
return client.post(endpoint, data, {
    onUploadProgress: (progress) =>
        onUploadProgress(progress.loaded / progress.total),
        
});
};
