dependency-analyzer

1. analyze js files

const path = require('path');
const { jsAnalyzer } = require('../index');

const fileTypeRegExp = /\.js$/;
const excludeRegExp = /node_modules/;

const base = path.resolve('../');
const moduleDir = 'node_modules';
const extensions = [
    '.js',
];
const mainFileName = 'index';

const graph = jsAnalyzer({
    base,
    moduleDir,
    mainFileName,
    extensions,

    fileTypeRegExp,
    excludeRegExp
});

console.log(JSON.stringify(graph.toJSON(), null, 4));

This will get the dependencies of the current project, the dependent graph is shown as an adjacency list.

{
    "/Users/thzt/Github/dependency-analyzer/example/current-project.js": [
        "path",
        "/Users/thzt/Github/dependency-analyzer/src/index.js"
    ],
    "/Users/thzt/Github/dependency-analyzer/src/find-js-deps.js": [
        "fs",
        "path",
        "/Users/thzt/Github/dependency-analyzer/node_modules/precinct/index.js",
        "/Users/thzt/Github/dependency-analyzer/util/is-file.js",
        "/Users/thzt/Github/dependency-analyzer/util/get-dir.js"
    ],
    "/Users/thzt/Github/dependency-analyzer/src/index.js": [
        "/Users/thzt/Github/dependency-analyzer/util/find-files.js",
        "/Users/thzt/Github/dependency-analyzer/util/create-dep-graph.js",
        "/Users/thzt/Github/dependency-analyzer/src/find-js-deps.js"
    ],
    "/Users/thzt/Github/dependency-analyzer/util/create-dep-graph.js": [

        "path",
        "/Users/thzt/Github/dependency-analyzer/node_modules/recursive-readdir-sync/index.js"
    ],
    "/Users/thzt/Github/dependency-analyzer/util/find-matches.js": [],
    "/Users/thzt/Github/dependency-analyzer/util/get-dir.js": [],
    "/Users/thzt/Github/dependency-analyzer/util/graph.js": [
        "/Users/thzt/Github/dependency-analyzer/util/union.js"
    ],
    "/Users/thzt/Github/dependency-analyzer/util/is-file.js": [
        "fs"
    ],
    "/Users/thzt/Github/dependency-analyzer/util/union.js": []
}

2. analyze user-defined dependencies

const { jsAnalyzer, createDepGraph } = require('../index');

We can use jsAnalyzer to get the dependencies of js files.

Besides, we can also use createDepGraph to analyze any user-defined dependencies,

by passing vertexes and a strategy findEdges to it.
