Serverless Prototypes

Goal:

• Isolate larger goals of a serverless projects into smaller easier to deploy prototypes
• Helps with isolation and reproducability

Other serverless apss:

• https://github.com/aizatto/build.my
• https://github.com/aizatto/url-shortener

See my Serverless notes:

Simple Template

What I use to create templates:

serverless create --template hello-world --path $PATH

TypeScript:

serverless create --template aws-nodejs-typescript --path $PATH

Keywords

• Prototypes
• Toys
• Tests
