Alternative solutions

This is not the only solution, and you might also want to look at:

Alex Nordlun’s Node plugin: It enables the use of a number of technologies related to node, including npm, yarn and pnpm. It bootstraps node as well.
Craig Burke’s Client Dependencies plugin: Install client side dependencies from npm or bower by declaring dependencies in build.gradle.
Cronn Pnpm plugin: A Gradle plugin that provisions pnpm and integrates a pnpm workspace into a Gradle build. It seems to have a focus on where a pnpm-driven monorepo is the layout of the repository, and some Gradle is added into the root of the repo alongside the pnpm root layout.
Jef Stano’s NPM plugin: Generic npm/node build lifecycle support for use within MSP.
Moowork’s Node plugin: Gradle plugin for executing node scripts (supports npm, yarn, grunt and gulp).
Palantir NPM plugin: A Gradle Plugin to create lifecycle tasks that trigger npm run commands.
Takuya Kuwahara’s Yarn plugin: Allows any yarn commands to be run in a Gradle build script. It has not been maintained in a long time and will probably not work with any Gradle 7+.
