See dependency graph within npm module

Question

Is there an NPM module that can show the dependencies between individual JS files within a module?

Suppose I have 20 JS files in my own NPM module; I'd like to see the dependency tree between my 20 JS files.

You know you wouldn't be sure there's no other dependency, as the imports are dynamically resolved, right ? (not pretending a graph of the obvious dependencies wouldn't make sense) — Denys Séguret

I'm not sure I follow. A trail through a dependency starts with a require() statement. Simply following them recursively is a relatively trivial problem. I'm also excluding dependencies from package.json, e.g, require('some-module-from-npmjs.org') will be thrown away whereas require('./utils/calculator.js') will be followed. — kevin628

I mean it's legit to do let randomModule = require(names[Math.random()*names.length|0]);. Or something more useful but still dynamic. Of course there are some obvious dependencies, but, but also non obvious ones. — Denys Séguret

Ah, true. I hadn't thought about that. Let's assume that all require() statements are fully "knowable": require('./util/calculator.js'). — kevin628

Some tools are available to graph the obvious dependencies (the ones you can guess from a static analysis).

I made myself a convenience wrapper around this great tool to quickly open a dependency graph image from the CLI and delete it afterward: gist
