How to upload image to firebase using react native - react-native

Question

I need way to upload image to firebase
i tried to use react-native-fetch-blob library
but I think there is something wrong with installing the library

Answer 1

No need to use react-native-fetch-blob. Here is how I do it on my project.
Install both react-native-firebase and react-native-image-picker. Follow the installation steps from their documentation guide.
Then implement 2 small functions to do image pick and upload to firebase. Here is the sample code.
// 1. Import required library
import firebase from 'react-native-firebase';
import ImagePicker from 'react-native-image-picker';
// 2. Create a function to pick the image
const pickImage = () => {
return new Promise((resolve, reject) => {
ImagePicker.showImagePicker(pickerOptions, response => {
if (response.didCancel) return;
if (response.error) {
const message = `An error was occurred: ${response.error}`;
reject(new Error(message));
return;
}
const { path: uri } = response;
resolve(uri);
});
});
};
// 3. Create a function to upload to firebase
const uploadImage = async (fileName, uri) {
return new Promise(
(resolve, reject) => {
firebase
.storage()
.ref(`uploads/${filename}`)
.putFile(uri)
.then(resolve)
.catch(reject);
}
);
}
Then simply firing both function as you need, here is the sample to pick and immediately upload it.
const pickImageAndUpload = async () => {
const uri = await pickImage();
const fileName = 'someImage.jpg';
const { state, downloadURL } = await uploadImage(fileName, uri);
}

async function uploadImageAsync(itemImage, passedParameter, ItemName, ItemDesc, ItemPrice, ItemWeight) {
const response = await fetch(itemImage);
const blob = await response.blob();
console.log("uri of the elements ius", blob)
var storageRef = firebase.storage().ref();
var file = blob
var metadata = {
contentType: 'image/jpeg',
};
const timeStamp = Date.now();
var uploadTask = storageRef.child('CategoryDescription' + "/" + `${passedParameter}` + "/" + `${ItemName}`).put(file, metadata);
//For image pick
pickImage = async () => {
const { CAMERA, CAMERA_ROLL } = Permissions;
const permissions = {
[CAMERA]: await Permissions.askAsync(CAMERA),
[CAMERA_ROLL]: await Permissions.askAsync(CAMERA_ROLL),
};
if (permissions[CAMERA].status === 'granted' && permissions[CAMERA_ROLL].status === 'granted') {
let result = await ImagePicker.launchImageLibraryAsync({
allowsEditing: false,
aspect:[4,3],
quality: 0.5,
});
// console.log(result);
if (!result.cancelled) {
this.setState({ itemImage: result.uri });
}
}
