Shrink node_modules for deployment

Introduction

!An illustration of the heaviest objects in the universe

Are you having problems getting node_modules down to a reasonable size?

``text
An error occurred (RequestEntityTooLargeException) when calling the UpdateFunctionCode operation: Request must be smaller than 69905067 bytes for the UpdateFunctionCode operation
`

Do you hit size limits, even when creating separate layers to contain dependencies?

`text
An error occurred (InvalidParameterValueException) when calling the UpdateFunctionCode operation: Unzipped size must be smaller than 262144000 bytes
`

Here's a utility that might help.

Quickstart

Zip up node_modules for Lambda

`bash
smaller-modules --zip --file dist/handler.js
`

Copy dependencies of compiled output to a new directory

`bash
smaller-modules --copy --directory dist --output-subdirectory smaller_modules
`

List dependencies of a .js file

`bash
smaller-modules --list --file dist/index.js --output-path dependencies.txt
`

or print it to the command line

`bash
smaller-modules --list --file dist/index.js
`

Usage

Zip up node_modules for Lambda (in long-hand)

`bash
smaller-modules --zip --file dist/index.js --output-subdirectory nodejs --output-path node_modules.zip
`

Use with packages in a mono-repository

`bash


Run from packages/


smaller-modules --list --file dist/index.js --base "../.."
