TypeError: goodFences is not a function when trying to use CLI

[bes]

Hello! Interesting project!

I'm trying to try it out. I've set up a few fence.json files just to get a feel of how things could work (currently using dependency-cruiser).

I've installed the CLI into node_modules using npm install @good-fences/api and I've set up a script in package.json:

{
  // ...
  "scripts": {
    // ...
    "good-fences": "good-fences"
  },
  // ...

Then I run it like so

$ npm run good-fences apps/app1 apps/app2 mylib

But unfortunately I'm met with

> good-fences
> good-fences apps/app1 apps/app2 mylib

.../myapps/node_modules/@good-fences/api/good-fences.js:24
const result = goodFences({
               ^

Node.js v22.13.1

What am I doing wrong?

P.S. A getting started guide would be awesome!

I got the same issue and didnt managed to solve it, it could be related to MAC not having glibc.

https://www.npmjs.com/package/dependency-cruiser is an interesting alternative 🙂
