Configuration

esy can be configured through .esyrc which esy tries to find in the following locations (sorted by priority):

  1. Sandbox directory: .esyrc
  2. Home directory: $HOME/.esyrc

The following configuration parameters available:

Note that some of them could be also controlled via corresponding environment variables.

esy-prefix-path​

Prefix path controls the location where esy puts its installation caches and build store. By default it is set to $HOME/.esy. To override the default location put the following lines into .esyrc:

esy-prefix-path: "/var/lib/esy"

If relative path is provided then it will be resolved against the directory .esyrc resides in.

Prefix path could also be set using $ESY__PREFIX environment variable.

yarn-*​

Any of the yarn configuration parameters can be set in .esyrc similar to .yarnrc. See a corresponding yarn documentation on the matter.

Those parameters will be used by esy install and esy add commands (which use yarn under the hood).
