dependency-tree

返回节点 JavaScript 文件依赖项的本地路径的无序数组(它或其任何依赖项 require 的所有内容)。

dependency-tree package 的缩减功能(更快)替代品,仅适用于库存节点JS。 Eleventy 使用它来查找 JavaScript 文件的依赖项,以监视更改以重新运行 Eleventy 的构建。

Big Huge Caveat

⚠ 这个插件的一个重要警告是它需要这个文件来构建一个依赖树。 因此,如果您的模块有副作用并且您不希望它执行,请不要使用它!

Installation

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

Features

  • Ignores node_modules
  • Or, use nodeModuleNamesOnly to return a list of node_modules packages (added in v2.0.0)
  • Ignores Node’s built-ins (e.g. path)
  • Handles circular dependencies (Node does this too)

Usage

// my-file.js

// if my-local-dependency.js has dependencies, it will include those too
const test = require("./my-local-dependency.js");

// ignored, is a built-in
const path = require("path");
const DependencyTree = require("@11ty/dependency-tree");

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

allowNotFound

const DependencyTree = require("@11ty/dependency-tree");

DependencyTree("./this-does-not-exist.js"); // throws an error

DependencyTree("./this-does-not-exist.js", { allowNotFound: true });
// returns []

nodeModuleNamesOnly

(在 v2.0.0 中添加)导航所有本地文件并返回所需的唯一包名称(不是文件名)列表。

const DependencyTree = require("@11ty/dependency-tree");

DependencyTree("./this-does-not-exist.js", { nodeModuleNamesOnly: true });
// returns []

dependency-tree

Returns an unordered array of local paths to dependencies of a node JavaScript file (everything it or any of its dependencies requires).

Reduced feature (faster) alternative to the dependency-tree package that only works with stock node JS. This is used by Eleventy to find dependencies of a JavaScript file to watch for changes to re-run Eleventy’s build.

Big Huge Caveat

⚠ A big caveat to this plugin is that it will require the file in order to build a dependency tree. So if your module has side effects and you don’t want it to execute—do not use this!

DependencyTree("./this-does-not-exist.js"); // throws an error

DependencyTree("./this-does-not-exist.js", { allowNotFound: true });
// returns []

nodeModuleNamesOnly

(Added in v2.0.0) Navigates all the local files and returns a list of unique package names (not file names) required.

const DependencyTree = require("@11ty/dependency-tree");

DependencyTree("./this-does-not-exist.js", { nodeModuleNamesOnly: true });
// returns []
