Serverless Plugin PKL

This is a Serverless Framework plugin that allows you to manage pkl-lang to use it as template var on sls configuration and upload it to S3 bucket explicitly or when a deployment is executed.

Installation

To install this plugin, navigate to your Serverless project directory and run the following command:

npm install --save-dev serverless-plugin-pkl --legacy-peer-deps

Then, add the plugin to your serverless.yml file:

plugins:
  - serverless-plugin-pkl

Usage

Configuration

To configure this plugin, you need to add a pklConfig section to the custom section of your serverless.yml file. Here is an example:

custom:
  pklConfig:
    file: path/to/config.pkl
    upload:
      bucket: my-bucket
      format: json
      create: true

In this configuration:

• file is the path to the main pkl file in your project.
• upload is an optional configuration that allows you to upload the pkl file to an S3 bucket.
  • bucket is the name of the S3 bucket where the pkl file should be uploaded.
  • format is the format in which the pkl file should be uploaded. By default, it is json, but you can specify yaml or xml to.
  • create is a boolean that specifies whether the bucket should be created if it does not exist. By default, it is true.

Templating in Serverless Configuration

PKL configuration is loaded at initialize step, so you can use the resultant configuration in your serverless file using mustache templating notation. Here is an example:

custom:
  someConfig: '{{ pkl:some.config }}'

provider:
  name: aws
  runtime: python3.8
  stage: '{{ pkl:stage }}'
  region: '{{ pkl:region }}'

Notes

Please note that this plugin requires the AWS provider and the bucket specified must already exist.
