AWS Lambda Development Template

This is the template I use to develop a Lambda Function locally and deploy them.

Usage

Prerequisites

• Lambda Execution Role
• AWS CLI

Setup your variables

You need to set FUNCTION_NAME and ARN_ROLE (Lambda Execution Role) at least.

cp sample.env .env

Create your function

$ yarn create
{
  "TracingConfig": {
    "Mode": "PassThrough"
  },
  "CodeSha256": "PFn4S+er27qk+UuZSTKEQfNKG/XNn7QJs90mJgq6oH8=",
  "FunctionName": "my-function",
  "CodeSize": 308,
  "RevisionId": "873282ed-4cd3-4dc8-a069-d0c647e470c6",
  "MemorySize": 128,
  "FunctionArn": "arn:aws:lambda:us-west-2:123456789012:function:my-function",

}
Done in 2.27s.

Deploy

Once you have all that you just need to edit the file for your needs and run:

$ yarn deploy
{
  "FunctionName": "my-function",
  "LastModified": "2019-09-26T20:28:40.438+0000",
