# AWS Lambda + Rekognition

This project shows you how to setup an S3 trigger whenever an image is added to

an S3 bucket. The trigger will invoke a Lambda function. This Lambda function

will call AWS Rekognition, and output the results in the same S3 bucket as a

JSON file.

## How to use

1. Clone this repo!

2. `yarn` to build everything.

3. Go to AWS Console.

4. Create a Node.js 8.10 Lambda function called "rekognize" with dummy

   Javascript. When you create the function, add a Role giving full access to

   CloudWatch, Rekognition, and S3. Bump up the timeout to 30 seconds.

5. `yarn run deploy` to deploy our code to this new Lambda function!

6. Go to your S3 bucket. We are going to add a trigger so that our

   function fires whenever a `png` image is added. Click the "Properties" tab.

   Expand the "Events" panel. Add a Lambda trigger that should look like this:

7. Test it! Upload a png image to the S3 bucket. In a moment or so, you will

   see a JSON file with the results. Cool!
