Learn how to build a reliable, scalable messaging system in Node.js by leveraging AWS Simple Queue Service (SQS) and Simple Notification Service (SNS).

This repository contains the code for the tutorial: AWS SQS and SNS Node JS tutorial: Integrating AWS SQS and SNS in a NestJS Application with TypeScript by Mobisoft - App Development Company, Houston

To run the project locally:

1. Clone the repository:

git clone https://github.com/mobisoftinfotech/sqs-sns-with-nest.git

2. Navigate to the project directory:

cd sqs-sns-with-nest

3. Install the dependencies:

npm install

4. Set up environment variables:

AWS_ACCESS_KEY_ID=<Your AWS Access Key> AWS_SECRET_ACCESS_KEY=<Your AWS Secret Key> AWS_REGION=<Your AWS Region> SNS_TOPIC_ARN=<Your SNS Topic ARN> SQS_QUEUE_URL=<Your SQS queue URL>

5. Start the development server:

npm start

The application should now be running on http://localhost:3000.

You can test the integration using a POST request to publish a message to SNS Or SQS:

• URL: http://localhost:3000/sns/publish
• Method: POST

{ "message": "Test SNS Message" }

Upon successful execution, you will receive a confirmation of the message being published to the SNS topic and sqs-consumer will consume the message and trigger handleMessage function also processed message entry will be saved in sqs_message table.

• URL: http://localhost:3000/sqs/publish

• Method: POST

{ "message": "Test SQS Message" }

Upon successful execution, you will receive a confirmation of the message being published to the SQS topic and sqs-consumer will consume the message and trigger handleMessage function also processed message entry will be saved in sqs_message table.

• Integration of SQS and SNS with Nest JS.
• Integration of sqs-consumer package for SQS messages polling
• Integration of SQLite DB to save processed messages

Enjoy exploring SQS and SNS with Nest JS!
