How to use in a nodejs app?

Hi chrisguttandin,

I’ve installed the package from npm and am running a nodejs app. I may be wrong but am struggling how I would be able to use worker-timers in my client pages. Does it need a reqiure() function on the client side? can you show me an example?

e.g. should it be using node_module/worker-timers/build/es5/bundle.js in the client page like: import * as workerTimers from '.libs/bundle.js'; or <script src=".libs/bundle.js"></script>

Looking forward to your reply. Thanks

Hi @ctlkkc, sorry for the confusion. The naming is a bit misleading. It’s definitely true that naming is one of the hardest problems in software development. 😃 The file bundle.js is not a bundle which can be loaded with a script tag. It’s called bundle because it bundles all source files, but it does NOT bundle any dependencies. In other words you need to create a bundle which contains your code, worker-timers and it’s dependencies. Here is a simplified example how you could do that with webpack. But any other bundler should work as well.

Create a file with your code which imports worker-timers. Let’s call it script.js.

import { setTimeout } from 'worker-timers';

setTimeout(() => {
    console.log('one second elapsed');
}, 1000);

Now you can use the webpack-cli with script.js as the entry point. webpack will look up all dependencies and create a single combined file. Just run the following command in your working directory:

webpack-cli script.js 

You can of course provide an extensive configuration but it should also work without any configuration at all. By default webpack will save the bundle as dist/main.js. This is the bundle which you can reference with a script tag.

<script type="text/javascript" src="dist/main.js"></script>

I hope this helps.
