webpacker-pnpm

version status downloads license Buy a tree

webpacker-pnpm replaces Rails' Yarn environment with pnpm, a better, smarter, and more efficient Node.js package manager. As a result, applications become less prone to dependency hell, more functional, more stable, and more flexible. And as an added bonus, dependency resolution times and node_modules folder sizes reduce to within reasonable ranges (not 45 seconds and 10 GiB).

You can read about the philosophy and technology behind pnpm in this convincing blog post by Zoltan Kochan (https://www.kochan.io/nodejs/why-should-we-use-pnpm).

Features

  • Production-ready
  • Drop-in replacement for Yarn
  • Supports Rails' Template API, including existing templates using Yarn
  • Provides code sanity without the migraines
  • Gives you more disk space

Installation

In order to use webpacker-pnpm, you must install pnpm. The official instructions are here.

After installing pnpm, first add webpacker-pnpm to your app's Gemfile.

gem "webpacker-pnpm"

Secondly, add the following line to your ./bin/webpack so it looks like below (the order matters). This step is required as Webpacker spawns a new process isolated from the Rails server (and thus all auto-loaded patches) when compilation happens live.

require "webpacker/webpack_runner"
require "webpacker/pnpm/patches" if ENV["RAILS_ENV"] != "production"
