I'm trying to accomplish the following task: I need to download image from url, then upload it to S3 storage and return the location of the uploaded file. I'm using async/await functions to do the task, but it returns Promise { pending } and after few seconds returns the location, i want to return location after promise is resolved. Here is my code:
// Space config
const spaceEndPoint = new AWS.Endpoint("fra1.digitaloceanspaces.com");
const s3 = new AWS.S3({
endpoint: spaceEndPoint,
accessKeyId: "xxxxxxxxx",
secretAccessKey: "xxxxxxxxxxxxxxxxx",
});
// Download image from url
const downloadImage = async (url) => {
try {
const file = axios
.get(url, {
responseType: "stream",
})
.then((res) => res.data)
.catch((err) => console.log(err));
return file;
} catch (err) {
console.log(err);
}
};
// Upload to space
const upload = async (fileUrl) => {
// Get file name from url
const fileName = path.basename(fileUrl);
// Path to save tmp file
const localFilePath = path.resolve(__dirname, "../downloads", fileName);
// Download file
const file = await downloadImage(fileUrl);
// Write file to disk
await file.pipe(fs.createWriteStream(localFilePath));
// Upload params
const params = {
Bucket: "sunday",
Body: fs.createReadStream(localFilePath),
Key: path.basename(fileName),
ContentType: "application/octet-stream",
ACL: "public-read",
};
const { Location } = await s3.upload(params).promise();
return Location;
};
console.log(
upload(
"https://i.pinimg.com/474x/e9/62/7c/e9627ce6fe731ba49597d3a83e21e398.jpg"
).then((data) => data)
);
// Result:
Promise { <pending> }

So i want to return location when promise is resolved. Thanks in advance for help!
Your function upload is async and thus always returns a promise that should be awaited too. await your upload call. If you're in environment that doesn't support top level await, use .then to log results instead or put outer logging code in helper function.
