serverless-plugin-zip-symlinks-compress-harder

Serverless plugin to improve artifact creation

This plugin for serverless will improve artifact creation. It uses some custom flags for Info-ZIP's command line to reduce artifact file size through:

• Use the -9 compression flag for max compression
• Use the -y flag to include symlinks as links not duplicates of the file
• Use the -FS flag to ensure the latest version of a file is in the archive, and remove any file in the archive that isn't in the source directory any more

To use this plugin

• yarn add serverless-plugin-zip-symlinks-compress-harder --dev or npm install --save-dev serverless-plugin-zip-symlinks-compress-harder
• Add serverless-plugin-zip-symlinks-compress-harder to the plugins section of your serverless.yml
• Add artifact: something.zip to the package section of your serverless.yml
