## プロジェクトの歴史と使われ方

ndenv is Ryosuke Iwanaga's rbenv-style Node.js version manager. Its README describes it as similar to rbenv, able to manage multiple Node.js and io.js versions, and able to switch automatically using a per-project `.node-version` file.

### プロジェクトの歴史

The GitHub API reports the riywo/ndenv repository was created on June 20, 2013. The README says almost all of the code came from rbenv, making ndenv part of the wave of language runtime managers that copied rbenv's shim-and-version-file model into other ecosystems.

The project's own README marks ndenv deprecated, recommends nodenv, and says the repository is not maintained actively. Homebrew also marks the formula deprecated and lists August 24, 2026 as the disable date, with nodenv as the recommended replacement.

### 採用の歴史

ndenv's practical adoption path was narrow but clear: developers who liked rbenv's automatic local version switching for Ruby could use a similar workflow for Node before nodenv, fnm, mise, asdf-nodejs, and other tools became common.

On July 1, 2026, Homebrew Formulae listed only 61 ndenv installs in its 365-day analytics window. That small number matches the upstream deprecation note and the ecosystem shift toward maintained replacements.

### 使われ方

The old workflow was to install ndenv, initialize shell integration, install node-build as the installer plugin, run commands such as `ndenv install v0.12.0`, and commit `.node-version` so entering a project directory selected the expected runtime.

The broader `.node-version` convention outlived ndenv. Independent compatibility research lists many tools that read `.node-version`, while noting that the file has no single formal standard.

### パッケージ好きにとっての重要性

ndenv matters less as a package to install than as a fossil in the version-manager lineage: rbenv semantics, Node/io.js era naming, node-build plugin dependency, and a clean migration story to nodenv.
