autonvm.fish

Automatic node version switching on directory change for the Node.js version manager nvm.fish.

Calling nvm use automatically in a directory with a .nvmrc or .node-version file.

This is a pure fish implementation and therefore no bash converting tools are required.

100% pure Fish—so simple to contribute to or tweak
.node-version and .nvmrc support
No setup needed—it just works!

Installation

Requires nvm.fish:

fisher install jorgebucaran/nvm.fish

Install with Fisher:

fisher install db-it/autonvm.fish

How it works

When the variable $PWD changes, autonvm.fish first looks for an .nvmrc file and then for a .node-version file. If one of the two files is found in the current directory, it checks if the required version is installed. If this is the case, nvm use is called with the version found in one of the two files. Otherwise, you will be asked to install the required version.

If none of the files is found in the current directory, autonvm.fish moves up the directory tree until one is found. Otherwise, the default version is used if it is set.
