What are the steps to add an NPM package to JSFiddle?

Can the valid-url be utilized for URL validation in JSFiddle to facilitate sharing afterwards? An attempt was made by linking the index.js file from Github (https://raw.githubusercontent.com/ogt/valid-url/master/index.js) but Fiddle responded with:

Github is not a CDN, using it as such will cause issues with loading the file. Do you still wish to proceed?

As expected, an error occurs when attempting to use it:

Refused to execute script from [...] because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.

Is there a method to incorporate npm packages within a JSFiddle environment? Or any workaround that could achieve this purpose?

Answer №2

By utilizing UNPKG, you have the capability to load any file from any package by adhering to this specific format

https://unpkg.com/:package@:version/:file

For instance, if you input

https://unpkg.com/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="b3c5d2dfdaf79ec6c1dff3829d839d8a">[email protected]</a>/

You will receive this result (as depicted in the following image)

If you specifically specify the index.js file

https://unpkg.com/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0375626f6a672e76716f43322d332d332a">[email protected]</a>/index.js

You will then acquire this output (as illustrated in the subsequent image)

This will allow you to incorporate it into your projects by simply adding the necessary resources.

Answer №3

If you're looking to import something from npm directly on the frontend, you can utilize a tool like which converts npm modules into ES Modules. An example of how to do this is shown below:

<script type="module">
  // Simply use 'https://cdn.skypack.dev/' followed by the 'npm package name' and optionally '@version'
  import random from 'https://cdn.skypack.dev/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="066567687067752b756d6372656e2b73726f6a46372837362836">[email protected]</a>/random'

  console.log('A random number: ', random.range(1,10))
</script>

Feel free to check out this JSFiddle example using SkyDev to load an npm module.

In scenarios where may not suffice, could be the solution. It's recommended for front-end usage in such cases.
