Great .zip packager and S3 uploader for AWS Lambda. Bundles only your prod dependencies
that are already installed, no need to prune or copy to a temp directory
and do a fresh install. And it even works with dependencies installed by
pnpm!
Supports:
- Scoped packages
- Same filename as
npm pack, except for extension prepackpackage script--dry-run--pack-destination
Doesn't currently support:
- Packing other packages in args
postpackpackage script--json--workspace--workspaces
The default filename is [name]-[version].zip where [name] is the package name (scoped names like @foo/bar
get converted to foo-bar) and [version] is the package version. If the version ends in -development,
a timestamp will be appened like [name]-[version]-[timestamp].zip so that the filename is always different
and a CloudFormation stack update will always update the Lambda code.
You can add the following config to package.json:
{
"@jcoreio/pack-lambda": {
/**
* Excludes dependencies from getting bundled
* (aws-sdk is pre-installed in the Lambda runtime so you could do this to save space)
* This has no effect if your package.json contains bundledDependencies
*/
"excludeDependencies": ["aws-sdk"]
}
}npx --package @jcoreio/pack-lambda pack-lambda
pack .zip file for AWS Lambda
Options:
--version Show version number [boolean]
--help Show help [boolean]
--dry-run display contents without writing file
[boolean] [default: false]
--pack-destination directory in which to save .zip files [string]
