Build Issue

[anywhichway]

I have installed your NPM package and tried running npm install in the node-modules/rakam directory. I have also cloned your repository and tried an install. Both fail. I have also tried npm run build in both places and it fails.

In node-modules/rakam:

npm install
npm WARN deprecated fsevents@1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.

> rakam@1.0.0-1 prepare /home/syblackwell/git/downrunner/node_modules/rakam
> npm run lint && npm run test


> rakam@1.0.0-1 lint /home/syblackwell/git/downrunner/node_modules/rakam
> eslint src/ --fix


Oops! Something went wrong! :(

I am so sad for my delay, I really should pay attention to the people wanting to accomplish their projects easily and quickly. I hope you have found a solution for your project.
For this issue: you were testing the installed node module, you should use that package directly with the require function or with ES6's import, and a bundler to get your script ready for the browser.
Insha'allah, I will put a URL for the ready-to-run script to put directly in the HTML:

<script src="https://url/for/rakam.js"></script>

You have corrected your mistake and cloned the git repo to do lint and test tesks. But you would have build first.

I have just noticed my silly bug in package.json, the task prepare runs before executing install. So the test is done before building, the bundled file ./main/index.js is required by the test files.
