Command line tool deploy code to AWS Lambda.


$3

Versions prior to 1.0.5 suffer from "Command Injection" vulnerability,
thanks snyk.io and Song Li of Johns Hopkins University for reporting.

Installation

``
npm install -g aws-lambda
`

WARN: upgrading to v1.0.0 will remove your function environment and layers if they are not defined in the config file

Config file

* PATH must point to your code folder and is relative to the config file
* PATH can be relative or absolute
* If not set, Runtime defaults to nodejs10.x
* If not set, FunctionName defaults to the name of the config file ("my-function" in this case)
* You can use Ref to reference environment variables in the form of env.YOUR_ENVIRONMENT_NAME
* lambda deploy credentials needs permissions to CreateFunction, UpdateFunctionConfiguration and UpdateFunctionCode
* lambda delete credentials needs permissions to DeleteFunction
* lambda invoke credentials needs permissions to InvokeFunction

unlike json, comments are allowed in yaml, yey!

remember to use spaces not tabs 😞

Deploy from Local to AWS Lambda

`
// if installed globally then
$ lambda deploy /path/to/my-function.lambda
$ lambda deploy ../configs/my-function.lambda

// if 'npm installed' without the -g then you must use the full path
$ node_modules/.bin/lambda /path/to/my-function.lambda

// you can also add it in your scripts section of your package.json scripts: { "deploy-func1": "lambda deploy ../config/func1.lambda" }
$ npm run deploy-func1
`

Watch config file

aws-lambda can also watch the config file and the code folder specified in the config.PATH for changes and re-reploy on change

`
$ lambda start ../configs/my-function.lambda
