In this workshop we will deploy a Node.js API where each API endpoint is powered by a Lambda function. Web traffic reaches the Lambda functions via an AWS API Gateway. The entire architecture is setup and deployed using the Serverless framework.
If you have not done so already create a development machine on AWS to do this workshop.
If you don't already have an SSH session open, SSH to your development machine.
ssh -i ~/.ssh/<your key>.pem ec2-user@<your dev machine ip address>
If you haven't already done so clone the workshop code onto the dev machine:
cd ~
git clone https://github.com/nathanpeck/nodejs-aws-workshop.git
Then change your current working directory to the right directory for this section of the workshop:
cd ~/nodejs-aws-workshop/3\ -\ Serverless\ Lambda/code
Now install the Serverless framework on your dev machine:
npm install -g serverless
Change your current working directory to the project directory then deploy using Serverless:
cd ~/nodejs-aws-workshop/3\ -\ Serverless\ Lambda/code
serverless deploy
In the output from the previous deploy step you will see a list of the API routes that were setup. Try fetching one of them in your browser.
For example:
curl https://dvlc67ufq7.execute-api.us-east-1.amazonaws.com/dev/api/characters
curl https://dvlc67ufq7.execute-api.us-east-1.amazonaws.com/dev/api/characters/by-species/vampire
Check out the AWS console to see a list of the lambda functions that were created by Serverless:
And to see how HTTP traffic gets to your Lambda functions you should check the API Gateway console
You can modify any function, and redeploy by once again running:
serverless deploy
Destroy all created resources by using
serverless remove
