How to upload an image to Google Cloud Storage from an image url in Node?

Question

Given an image url, how can I upload that image to Google Cloud Storage for image processing using Node.js?

Answer 1

I used the request library and storage library for make it. The code below is in TypeScript. Regards

import * as gcs from '@google-cloud/storage';
import {Storage} from '@google-cloud/storage';
import request from 'request';

private _storage: Storage;

constructor() {
    // example of json path: ../../config/google-cloud/google-storage.json
    this._storage = new gcs.Storage({keyFilename: 'JSON Config Path'});
}

public saveFileFromUrl(path: string): Promise {
    return new Promise((resolve, reject) => {
        request({url: path, encoding: null}, (err, res, buffer) => {
            if (res.statusCode !== 200) {
                reject(err);
            }
            const bucketName = 'bucket_name';
            const destination = `bucket location and file name`; // example: 'test/image.jpg'
            const file = this._storage.bucket(bucketName).file(destination);
            // put the image public
            file.save(buffer, {public: true, gzip: true}).then(data => {
                resolve(`${bucketName}/${destination}`)
            }).catch(err => {
                reject(err);
            });
        });
    })
}
