Instructor: Npx can actually run code that is stored in a Github gist. Let's get started and make one.
Then we'll create a package.json file and include a name for our project, "JS from terminal with npx." We'll give it a version of 1.00and point to the index.js file from above. Now we'll save our new gist and grab the URL from the address bar.
If we go over to our terminal and type npx followed by the gist URL that we just copied, then wham, the code from the gist will execute. Your gist could be much more complex than just a console.log.
At that point, the returned string is split into an array. Empty lines are filtered out. The remaining items are mapped into Markdown. Then the array is joined back together. Finally, the results are console.logged at the end.
As before, if we grab the URL and come over to our terminal, we can npx and paste our URL. Voila, here is a list of our installed VS Code extensions. I could come back in and pipe the results to pbcopy to store that in my copy/paste buffer and open up a Markdown editor.
Here, I'm using Macdown to verify that sure enough the content is valid Markdown. Here on the right, you could see the list of extensions I have installed.
Keep in mind, if you're using a gist URL to run via npx, you need to trust the source you're about to run in case there is any malicious code. Other than that, it's pretty cool.
