How do I test if a bucket exists on AWS S3 using the aws-sdk?
This question is for testing if an object exists within a bucket: How to determine if object exists AWS S3 Node.JS sdk
This question is for Python: How can I check that a AWS S3 bucket exists?
You can use the following code:
// import aws-sdk as AWS
// const AWS = require('aws-sdk');
const checkBucketExists = async bucket => {
const s3 = new AWS.S3();
const options = {
Bucket: bucket,
};
try {
await s3.headBucket(options).promise();
return true;
} catch (error) {
if (error && error.statusCode === 404) {
return false;
}
throw error;
}
};
The important thing is to realize that the error statusCode
will be 404
if the bucket does not exist.
