AWS S3 with Python

In this example we will see the basic operations that we can do with the cube and the files

Installation

pip install boto3
Enter fullscreen mode Exit fullscreen mode

Connection

from boto3 import client
from os import getenv

clientS3 = client("s3",
                  aws_access_key_id=getenv("AWS_ACCESS_KEY_ID"),
                  aws_secret_access_key=getenv("AWS_SECRET_ACCESS_KEY"),
                  region_name=getenv("REGION_NAME")
                  )
Enter fullscreen mode Exit fullscreen mode

Methods for buckets

Create bucket

from botocore.exceptions import ClientError

def create_bucket(bucket: str):
    try:
        response = clientS3.create_bucket(Bucket=bucket)
        return response
    except ClientError as e:
        return e.response["Error"]
Enter fullscreen mode Exit fullscreen mode

Delete bucket

from botocore.exceptions import ClientError

def delete_bucket(bucket: str):
    try:
        response = clientS3.delete_bucket(Bucket=bucket)
        return response
    except ClientError as e:
        return e.response["Error"]
Enter fullscreen mode Exit fullscreen mode

List all buckets

from botocore.exceptions import ClientError

def list_buckets():
    try:
        response = clientS3.list_buckets()
        return response
    except ClientError as e:
        return e.response["Error"]
Enter fullscreen mode Exit fullscreen mode

Methods for files

Upload file

from typing import BinaryIO
from botocore.exceptions import ClientError

def upload_file(data: BinaryIO, bucket: str, filename: str):
    try:
        clientS3.upload_fileobj(Fileobj=data, Bucket=bucket, Key=filename)
        return "success"
    except ClientError as e:
        return e.response["Error"]
Enter fullscreen mode Exit fullscreen mode

Get file

from typing import BinaryIO
from botocore.exceptions import ClientError

def get_file(bucket: str, filename: str):
    try:
        response = clientS3.get_object(Bucket=bucket, Key=filename)
        return response
    except ClientError as e:
        return e.response["Error"]
Enter fullscreen mode Exit fullscreen mode

Delete file

from typing import BinaryIO
from botocore.exceptions import ClientError

def delete_file(bucket: str, filename: str):
    try:
        response = clientS3.delete_object(Bucket=bucket, Key=filename)
        return response
    except ClientError as e:
        return e.response["Error"]
Enter fullscreen mode Exit fullscreen mode

An Animated Guide to Node.js Event Loop

Node.js doesn’t stop from running other operations because of Libuv, a C++ library responsible for the event loop and asynchronously handling tasks such as network requests, DNS resolution, file system operations, data encryption, etc.

What happens under the hood when Node.js works on tasks such as database queries? We will explore it by following this piece of code step by step.
