## プロジェクトの歴史と使われ方

`ni` is Anthony Fu's JavaScript package-manager dispatcher: one set of short commands that detects whether a project uses npm, Yarn, pnpm, Bun, or Deno and runs the matching package-manager command.

### プロジェクトの歴史

The npm registry metadata for `@antfu/ni` shows the package created on November 5, 2020. The project later moved under the `antfu-collective` GitHub organization while keeping the author ecosystem around Anthony Fu's JavaScript tooling.

The README documents the core idea as lockfile and package metadata detection. It maps `ni`, `nr`, `nlx`, `nup`, `nun`, `nci`, `nd`, and `na` onto equivalent npm, Yarn, pnpm, Bun, and Deno operations, and uses the separate `package-manager-detector` package for detection.

### 採用の歴史

The tool became a small package-nerd convenience in the Node ecosystem because frontend and monorepo developers often switch between repositories with different lockfiles. Homebrew analytics on July 1, 2026 reported 1,661 install-on-request events over 365 days, and the npm package was modified as version 30.2.0 on June 25, 2026.

The ecosystem signal is not that `ni` owns dependency installation, but that it standardizes muscle memory. Its README includes Homebrew and asdf installation paths, auto-install support for missing package managers, and configuration through `~/.nirc` or environment variables.

### 使われ方

Practical usage is intentionally tiny: run `ni` to install dependencies, `nr` to run scripts, `nlx` to download and execute a package, `nup` to upgrade, `nun` to uninstall, `nci` for clean/frozen installs, and `na` to invoke the detected package manager itself. The tool detects `yarn.lock`, `pnpm-lock.yaml`, `package-lock.json`, `bun.lock`, `bun.lockb`, `deno.json`, `deno.jsonc`, or the `packageManager` field.

### タイムライン

- {'date': '2020-11-05', 'event': '`@antfu/ni` npm package created.'}
- {'date': '2026-06-25', 'event': 'npm metadata listed version 30.2.0 as the latest package version.'}
