Amazon Simple Storage Service (S3) is a highly scalable object storage service offered by AWS. Here's how you can use S3 for storing images and videos: Create an S3 Bucket: Log in to the AWS Management Console, navigate to the S3 service, and create a new bucket. This bucket will serve as the storage location for your images and videos. Set Up Permissions: Configure access control policies for your S3 bucket to control who can upload, download, and manage objects stored in the bucket. You can use IAM policies to define permissions for specific users or roles. Upload Images and Videos: Use the AWS SDK or AWS Management Console to upload images and videos to your S3 bucket. You can also configure lifecycle policies to automatically move or delete objects based on predefined rules.
AWS Lambda is a serverless compute service that allows you to run code without provisioning or managing servers. You can use Lambda to execute backend logic for your application. Here's how you can host your project using Lambda and API Gateway: Deploy Backend Code to Lambda: Package your Node.js/Express.js backend code into a deployment package and upload it to AWS Lambda. You can define Lambda functions to handle different API endpoints or business logic. Set Up API Gateway: Create an API using Amazon API Gateway to expose your Lambda functions as HTTP endpoints. API Gateway acts as a proxy between your frontend and backend, allowing you to define RESTful APIs and manage requests/responses. Configure CORS: Enable Cross-Origin Resource Sharing (CORS) on your API Gateway to allow your frontend application hosted elsewhere to make requests to your API. Integrate Frontend with Backend: Update your frontend code to make API requests to the endpoints exposed by API Gateway. You'll need to handle authentication, request validation, and response parsing in your frontend code.
Node.js:
- You'll become proficient in server-side JavaScript programming with Node.js. Express.js:
- Express.js will be your go-to framework for building robust and scalable backend APIs. MongoDB:
- You'll learn how to work with MongoDB, a NoSQL database, and perform CRUD operations using Mongoose ODM (Object Data Modeling). AWS Lambda:
- You'll gain experience with serverless computing by deploying backend logic as Lambda functions. AWS API Gateway:
- You'll learn how to create RESTful APIs and manage endpoints using API Gateway to communicate with Lambda functions. AWS SDK for JavaScript:
- You'll utilize the AWS SDK to interact with AWS services programmatically, including Lambda and API Gateway.
React.js:
- You'll master frontend development using React.js, a popular JavaScript library for building user interfaces. HTML/CSS:
- You'll use HTML and CSS for structuring and styling your frontend components. React Router:
- React Router will enable you to implement client-side routing in your React application. Axios or Fetch API:
- You'll make HTTP requests from your frontend to your backend API using Axios or the Fetch API. Redux (Optional):
- If you choose to implement Redux, you'll learn state management techniques for handling complex application states.
