esvu is your one-stop shop for all implementations of ECMAScript.

Installation

$ npm i -g esvu

Add ~/.esvu/bin to your PATH.

Usage

The first time you run esvu, it will ask you which engines you wish to install. After the first run, running esvu will update the engines you selected.

• $ esvu Update all installed engines, or select engines to install
• $ esvu install <engine> Install the engine <engine>
• $ esvu uninstall <engine> Uninstall <engine>
• $ esvu update <engine> Update <engine>. Like install but the engine must have been previously installed.

If you're using eshost-cli, you can run eshost --configure-esvu after installing engines to make eshost automatically find the installed engines.
