Detect circular dependencies in project

Question

Last time i found in my project problem with circular dependencies. I resolve my problem but, i would like avoid this in future. I think about plugin which found circular dependencies in my all project and give me feedback.

Example:

File a.js:

var functionFromA= require("./b.js");
console.log("file a", functionFromA);
module.exports = {functionFromA: functionFromA};

File b.js:

var functionFromB = require("./c.js");
console.log("file b", functionFromB );
module.exports = {functionFromB : functionFromB };

File c.js:

var functionFromC = require("./a.js");
console.log("file c", functionFromC );
module.exports = {functionFromC : functionFromC }

When i run file a.js i see in console:
file c {}
file b { functionFromC: {} }
file a { functionFromB: { functionFromC: {} } }

I found "Circular Dependency Plugin" in npm but i don't know how use it? May be someone has similar problem and found a solution?

Answer 1

You can find this other tool useful: https://www.npmjs.com/package/madge

is very easy to use: madge --circular [directory] give you a list of circular dependencies in your code located inside [directory]. It can also generate a graph image.

Answer 2

As davidmpaz suggested, madge is a good tool for such a thing but it only detects circular dependencies and doesn't indicate whether these circular dependencies causes a problem in your application or not.

I made a tool to detect the circular dependencies and it warns you about the problem that caused by cd. https://www.npmjs.com/package/detect-circular-deps
