Using async/await syntax

Let’s take advantage of the latest ES8 (ES2017) features and use async/await syntax instead:

import {createConnection} from "typeorm";
import {Photo} from "./entity/Photo";
createConnection(/*...*/).then(async connection => {
    let photo = new Photo();
    photo.name = "Me and Bears";
    photo.description = "I am near polar bears";
    photo.filename = "photo-with-bears.jpg";
    photo.views = 1;
    photo.isPublished = true;
    await connection.manager.save(photo);
    console.log("Photo has been saved");
}).catch(error => console.log(error));
