AppSync Expense Tracker is a demo application that leverages a suite of AWS services for real-time, automated expense reporting. This application integrates AWS AppSync, Amazon Cognito, Amazon Textract, DynamoDB, and S3 to create a seamless yet simple user experience.
- Real-time Automated Expense Reporting: Utilizes AWS AppSync for instant data synchronization.
- Secure Authentication: Integrates Amazon Cognito for user authentication and management.
- Intelligent Document Processing: Employs Amazon Textract for accurate extraction of expense details from images.
- Scalable Database Storage: Uses DynamoDB for storing expense data with high availability.
- Reliable File Storage: Leverages S3 for secure storage of expense images.
The frontend of AppSync Expense Tracker is built using React and NextJS, providing a robust and scalable web application. AWS Amplify UI libraries are integrated to offer a rich UI experience and JavaScript client-side helpers for seamless AWS interactions.
- React and NextJS: Modern JavaScript frameworks for building interactive UIs.
- AWS Amplify UI Libraries: Pre-built UI components and workflows for AWS services.
The backend infrastructure is created using the AWS Cloud Development Kit (CDK), ensuring a programmatically defined, version-controlled, and reliable AWS environment.
- AWS CDK: Infrastructure as Code for defining cloud resources.
- Integration with AWS Services: Seamless connectivity with AWS AppSync, Cognito, Textract, DynamoDB, and S3.
- Expense Image Upload: Users can upload images of their receipts or bills.
- Data Extraction and Storage:
- Amazon Textract: Extracts details from the uploaded images.
- DynamoDB: Stores the extracted expense data.
- S3 Bucket: Stores the images, accessed via presigned URLs for security.
This application is a sample implementation and serves as a blueprint for building real-time, automated expense tracking solutions. The contents of the S3 bucket are accessible via presigned URLs, ensuring data security and integrity.
