Intro

serverless framework consists of an open source CLI and a hosted dashboard to provide you with full serverless application lifecycle management.

The purpose of the article is to provide you a quick configuration to get started with it.

Configure serverless to use AWS

serverless config credentials --provider aws --key <access-key-id> --secret <secret-access-key> --profile <profileName>

If you do not wish to provide secrets in the shell, use ~/.aws/credentials file to save credentials in the following format:

[<Enter profile name here>]
aws_access_key_id=*********
aws_secret_access_key=***************
[<Enter another profile name here>]
aws_access_key_id=*******************
aws_secret_access_key=**********************
Enter fullscreen modeExit fullscreen mode

Create a new project (nodejs)

serverless create --template aws-nodejs --path myServerlessProject

The following files are created:
handler.js
.npmignore
serverless.yml

In serverless.yml, add profile and region

In a shell, run
sls deploy

If anyone can tell me how to insert yaml in a dev.to article, I will replace the images. Using code blocks in markdown for yaml code removed indentation.
