@11ty/dependency-tree-esm v1.0.0

dependency-tree-esm

Returns an unordered array of local paths to dependencies of a Node ES module JavaScript file.

• See also: dependency-tree for the CommonJS version.

This is used by Eleventy to find dependencies of a JavaScript file to watch for changes to re-run Eleventy’s build.

Installation

npm install --save-dev @11ty/dependency-tree-esm

Features

• Ignores bare specifiers (e.g. import "my-package")
• Ignores Node’s built-ins (e.g. import "path")
• Handles circular dependencies
• Returns an empty set if the file does not exist.

Usage

// my-file.js

// if my-local-dependency.js has dependencies, it will include those too
import "./my-local-dependency.js";


// ignored, is a built-in
import path from "path";

const { find } = require("@11ty/dependency-tree-esm");

find("./my-file.js");
// returns ["./my-local-dependency.js"]
