How to load a local file for a clojurescript test

Question

I am writing some cljs.test tests for a clojurescript library and have some JSON test data I would like to load in.

I'm unsure what function I can use to load the data from files local to the project.

I'm using lein-doo as the test runner, initially with a nodejs configuration, ideally I would like to load files in an agnostic manner if possible, but I'd be fine with a nodejs-specific answer.

Take a look at http://stackoverflow.com/a/34557616/597473 - it covers loading a local file in CLJS running in NodeJS. — Piotrek Bzdyl, Aug 10 '16 at 19:56

Following Piotrek's link I have come up with the following nodejs-only function that accomplishes this:

(defn node-slurp [path]
    (let [fs (nodejs/require "fs")]
        (.readFileSync fs path "utf8")))

(Node documentation: File System - readFileSync)

This gives me the error: `No such namespace: nodejs, could not locate nodejs.cljs, nodejs.cljc, or JavaScript source providing "nodejs"` – Jim Feb 11 '18 at 02:54
Use `js/require`, rather than `nodejs/require`. – Phil Jackson Mar 02 '18 at 20:46
