import-tree

import-tree(WIP)

A super fast tool that uses swc to build JavaScript/TypeScript module import/require-relation tree.

Features

• :zap: Blazing fast ESM/CJS modules scanner
• :rainbow: Interactive module relation graph view
• :hammer_and_pick: Strict import diagnosis based on eslint-plugin-import rules [todo]
• :herb: Rich plugins support (vite, rollup, webpack) [todo]

Usage

import-tree is not only a cli tool, you can also use it as a JavaScript API or a specific bundler plugin.

Benchmark

import-tree tested its Nodejs api’s benchmark in multiple popular third-party git repos.
