Use this command: pip freeze > requirements.txt Procfile Create a Procfile (no file extension) in the root directory: we b: python app. py Replace app.py with the filename of your main Flask script if necessary. Step 2: Set Up a Git Repository Railway uses Git for deployment. Initialize a Git repository for your project: gi...

To implement file upload, list, download, and delete operations for AWS S3 in a Flask app, you can follow the steps below. This example will: Upload files to an S3 bucket. List files available in the S3 bucket. Download files from the S3 bucket. Delete files from the S3 bucket. Step 1: Install Required Libraries Make sure you have Flask and boto3 installed. pip install Flask boto3 Step 2: AWS S3 Configuration You will need AWS credentials and an S3 bucket. You can either: Set the AWS credentials as environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY). Or use the default AWS credentials file located at ~/.aws/credentials. Step 3: Flask Application with File Upload, List, Download, and Delete Here's a simple Flask app that integrates with AWS S3 for file upload, listing, downloading, and deleting. from flask import Flask, request, send_file, jsonify import boto3 from botocore.exceptions import NoCredentialsError import os # Initialize Flask app app = ...
