serverless-js-transpiler

0.1.1 verified Fri May 01 auth: no javascript

A Serverless Framework plugin for transpiling JavaScript to ES2015/16/17 using Babel. Version 0.1.1 is a work-in-progress with no recent releases. It integrates with the serverless lifecycle to transpile files before packaging or deployment. Compared to alternatives like serverless-webpack or serverless-bundle, this plugin is minimal but lacks maintenance and documentation.

Warnings

deprecated Package is WIP and no updates since initial release ↓

fix Use actively maintained alternatives like serverless-webpack or serverless-bundle.
