lambpack

A no nonsense AWS Lambda function packager for node.js— it walks the dependency tree of a lambda handler source file and packages it up into the smallest .zip file suitable for uploading to AWS Lambda.

Installing It

npm install lambpack -g

Using It

$ lambpack

  Usage: lambpack [options] <lambdaHandlerFile> <outputZipFileName> [otherFiles...]


  Options:

    -V, --version  output the version number
    -q, --quiet    quiet mode
    -i, --include-aws  include your own aws-sdk (if you depend on it), otherwise the Lambda globally installed version will be used
    -h, --help     output usage information

lambdaHandlerFile is the pathname of a .js file which contains your one and only Lambda.handler function.

outputZipFileName is the pathname of the .zip file you want to output the package.

otherFiles is a space or comma separated list of additional files or directories you may want to include within the deployment .zip file.

-i, --include-aws: Normally all Lambda functions have access to a globally installed aws-sdk package, so it's usually wasteful to upload it with your code (if you use it). However if there is a specific version in your package.json file that you want to use, you can use this switch to force it to include the one you specify. If you don't use aws-sdk at all in your code, then this switch won't really change anything.

Example

$ cd my_project
$ lambpack lambda.js ./deploy/lambda.zip

Follow the instructions to upload and enjoy your serverless existence!

Note: lambpack won't automagically solve the issue of packaging modules with native code— in which case you'll need to run lambpack on an AWS Linux EC2 instance. Check out lambda-packager if you want a more complex to setup, but very full-featured packager.
