Simple deploy to AWS lambda in 3 minutes

What is this

This is a simple example boilerplate used to demonstrate how we can deploy a serverless function to AWS Lambda in less than 3 minutes.

This talk was first presented on APICon Conference on March 23rd 2018. And has been updated and improved since then.

This function is simply a factorial API.

File contents

serverless.yml: Base template file definition for all functions inside the service (project)
handler.js: Base Javascript file to be read by AWS Lambda as function entrypoint

Running locally

You're gonna need Node.js at version 10, if you have NVM installed just issue nvm use inside the folder you want to run and it'll change the current version to 10.

After that install all packages using npm i then issue npm run deploy to deploy your function.

If you want to recreate

Install the Serverless Framework using npm i -g serverless or yarn global add serverless and then type sls deploy inside the project directory root.

Recreating AWS

After installing Serverless, from the step above, run serverless create --template aws-nodejs inside any folder, those two files serverless.yaml and handler.js will be created for you.

You can edit the definitions of the whole service inside the serverless.yaml file.

After that run sls deploy inside the same folder.

Don't forget to add your provider credentials

Recreating Azure

After installing Serverless, from the step above, run serverless create --template azure-nodejs inside any folder, those two files serverless.yaml and handler.js will be created for you.
