esvu

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

Installation

$ npm i -g esvu

esvu will attempt to respect XDG_DATA_HOME, and will fall back to the home directory. You will need to add esvu's bin to your PATH, for example $XDG_DATA_HOME/.esvu/bin or /home/snek/.esvu/bin.

You may override the path entirely by setting the ESVU_PATH environment variable.

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.
