how to download a js file from a server and run it?

Is it possible to run a js file locally that downloads a secondary file and then run the latter?
I know the best thing would be to download the file from the server and save it locally, I would just like to understand if there is still the possibility to do the above.
Example:
Open terminal
1- node index js
2 - download scripts js in the same directory as index.js
3 - download is complete, start script js automatically.

Even if it is possible to solve it with Node.js workarounds (like requireing your puppeteer script from an url etc.) I strongly suggest to use Git with your team to share the latest version of your script. Version control is a must in modern software development, especially if you are working in a team. By learning the 6-7 most basic git commands you can solve almost everything you need for the current use case.
There are many good tutorials how to get started with git, I recommend GitHub's https://try.github.io.
Of course: you need to convince your team to embrace the change, or in better case they are already using it for version control, so it will be familiar to them.
You will need to:
Install Git locally;
Create a new repository on a server where you can store the latest stable versions of all your scripts (if it is not an open source project make sure it is private! GitLab, GitHub and Bitbucket provides/hosts free private repositories that will suit your needs);
Share the HTTPS (or SSH) URL of the repository with your team (e.g.: https://github.com/.../puppeteer-scripts.git) which they can clone;
Make sure your changes are pushed to the remote git repository;
Your team can pull the latest changes to their local computer (it will be their responsiblity to check if there were changes in the scripts, but you can notify them as well - there are automatic notifications if one starts to "watch" a git repository);
Lastly
Git can be frightening at first sight, but it can be learned in a few days and it makes code sharing smooth within your team.
One of Git's tagline describes very well why it will solve your problem:
--everything-is-local

Android and Web App sharing Kotlin code

One of the major “selling” points of Kotlin appears to be its ability to compile both to JVM or Android and to JavaScript for the web. To make use of this, it should be possible to have a code base where some files are shared between an Android App and a browser Web App.
However, so far I found little details on how such a thing would be set up, in particularly when working with Android Studio and its underlying Gradle setup, starting from a a run of the Android Studio New Project Wizard. I don't mind if I can only build the Web App on the command line, but I'd like to maintain the Android debugging hookups that Android Studio provides. So far I know very little about Gradle and typical idioms for its use.
I'm sure that I'm not the first person to have this idea, so I'd like to know some best practices on how to set this up. Questions that come to my mind include the following:
Do I mix the kotlin2js and the kotlin-android plugin in a single build file, or do I need to have multiple build files (perhaps I should say “modules” or “projects” except I don't know which)?
If I have multiple build files, should that be two (one Android one Web) or three (one more for shared things)?
If it is two build files, how do I reference the shared sources?
If it is three build files, which plugin(s) do I use for the shared one?
Do I need to split my sources over three different source trees? Are there any conventions how these should be called?
Do I need to split my classes into three groups of packages, or can code for different targets coexist in the same package?
What configuration settings do I need to tweak to make the IDE aware of the layout of my project?
I've read the following relevant documentation, among other:
https://kotlinlang.org/docs/reference/using-gradle.html
https://docs.gradle.org/current/userguide/intro_multi_project_builds.html
https://docs.gradle.org/current/userguide/composite_builds.html
https://kotlinlang.org/docs/tutorials/kotlin-android.html

I would recommend using IDEA wizard to create a simple multiplatfrom project for you (File -> New -> Project -> Kotlin -> Kotlin (Multiplatform - experimental) ). Community edition should suffice.
Answering your questions:
You don't mix plugins. You create a separate module for your common code and use 'kotlin-platform-common' plugin for it.
Three modules, special plugin 'kotlin-platform-common'
Use common sense for source splitting. Put whatever you want/able to reuse in the common code. Put platform-specific code in platform modules.
No package restrictions. You can put everything in the same package if you so desire =)
Pretty sure it should just work. If not, try re-importing.

Reference common Javascript file in two solutions

/
..Common/Scripts/Script1.js
..Sharepoint2010/Layout/Scripts/[reference to Script1.js]
..Sharepoint2013/Layout/Scripts/[reference to Script1.js]
Developement for Sharepoint allows to deploy resources such as js and css files.
Different versions of Sharepoint have different metadata (project types, webparts, paths), but the source js/css are the same.
Programmatically it's best to have a signle copy of resource and use it from these different projects.
So editing Script1 in Sharepoint2010 project and saving it eventually result in updated Common/Script1.js which will be i.e. updated automatically for Sharepoint2013.
I'm relatively new to sharepoint, but I'm not searching for "use build options, cmd xcopy /sp2010/script1.js common/scripts/script1.js".
I'm using WebEssentials to simplify development, there are bundles, which defines path to resources and then compile these resources, but that doesn't work with the given scheme.

If I understood your problem correctly, "Add as link" option in Visual Studio can help you. The article is actually about Win8 development, but whatever.

Best practices for maintaining javascript libraries in repositories?

When developing javascript code, what are the best practices for maintaining the code in repositories?
For example, suppose I develop a set of useful functions and put them in a script called "sugar.js". In the code repository I put them in c:/codebase/suger.js.
Now I want to use the script in a web site being developed and I locate it at c:\mywebsite\sugar.js (ready for uploading to a server)
Do I keep a copy of sugar.js? What if I fix sugar.js in one location - it won't be synchronized with the other?
What if I build a second web site that also uses sugar.js? Do I take another copy located at, say, c:\mywebsite2\sugar.js?

If you are using something like visual studio, you can use NuGet for versioning many of the popular javascript frameworks on a per-project basis.
If you are writing in something else, you could try package managers such as npmjs or http://jspkg.com/JSPkg.
If it is your own library, I would recommend setting up source control and having versioned releases as branches or tags, that way you can keep track of everything. Git and GitHub support this type of thing, and you can set it up to have each version as a zipped download.
I would also try to keep each project's javascript files separate, that way any changes won't immediately break every site, just the one you recently updated. This advice could go out the window if you are running hundreds of sites and really just need a CDN.

Handling common JavaScript files in Visual Studio 2010

We're beginning work on a couple of fully JavaScript-dependent web apps (our previous apps have been ASP.NET MVC, with JavaScript 'goodness' sprinkled over-the-top).
We have a few files that will be shared across the board, and it would be nice to store these files in a Common project, and 'Add As Link' them into individual projects (as would be possible with compiled code).
Obviously this doesn't work with something like JavaScript as the file isn't actually 'there' in the correct location.
Does anyone have any suggestions on keeping a single version of a shared JavaScript file, for use across multiple projects?

I know this issue is ancient, but still wanted to put forward my solution because it is a bit simpler than beardtwizzle's.
You can ensure that Visual Studio copies all linked files to where you placed the link in Visual Studio's Solution Explorer by adding this at the end of your .csproj file:
<Target Name="CopyLinkedContentFiles" BeforeTargets="Build">
<Copy SourceFiles="%(Content.Identity)"
DestinationFiles="%(Content.Link)"
SkipUnchangedFiles='true'
OverwriteReadOnlyFiles='true'
Condition="'%(Content.Link)' != ''" />
</Target>
I've described how this works in my blog post at
http://mattperdeck.com/post/Copying-linked-content-files-at-each-build-using-MSBuild.aspx

In the end, this is how I've achieved it. It may not be to everyone's taste - but worked a treat for me.
Note: In all of our projects, static resources are in a root directory called 'Assets', so for example JavaScript is always in /Assets/js/ and CSS /Assets/css/.
Solution
In the project that is going to 'import' the common code, I simply add the common .js file 'As Link' within /Assets/js/.
Go to that new addition's Properties and set 'Copy to Output Directory' to 'Copy if newer'.
Now I simply edit the project's post-build event command line to the following:
xcopy /Y /E "$(TargetDir)\Assets" "$(ProjectDir)\Assets"
When the project builds, it copies the imported files to \bin\Assets\js - the post-build event then takes a copy of those over to the project directory - in time for the site to use them.

The correct solution is embedding javascript/css files in your project. You can do this by using WebResources.axd. This is the official way microsoft embeds js in its controls. (Like validation controls)
You can find a good tutorial on: https://web.archive.org/web/20211020131200/https://www.4guysfromrolla.com/articles/080906-1.aspx

I can also see this question is ancient, but thought I would add my two cents...
I have a javascript file in a separate project. I added a linked reference and this works well for publishing, but doesn't work in IIS Express or Casinni. I tried adding custom routing to catch the missing file and manually remap it, but it is bit of a hack and for some reason stopped working when I upgraded to MVC 5.1, so rather than fix the hack, I found a better way:
System.Web.Optimization has javascript bundles.
In your shared project, set the Copy To Output Directory to 'Copy Always' and Build Action to 'Content' on your js file. This means your js files end up in the bin folder of your website project. They cannot be served from there (IIS wont serve anything in the bin folder for obvious security reasons), but they can be included in bundles
using System.Web;
using System.Web.Optimization;
public class BundleConfig
{
public static void RegisterBundles(BundleCollection bundles)
{
bundles.Add(new ScriptBundle("~/bundles/externalLibrary").Include(
"~/bin/scripts/externalLibrary.js"
));
}
}
You then need to add this to Application_Start in your global.asax file (right next to register routes)
BundleConfig.RegisterBundles(System.Web.Optimization.BundleTable.Bundles);
then use your bundle link this in your razor cshtml:
<script type='text/javascript' src='#System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/bundles/externalLibrary")'></script>
you will need the nuget package for microsoft.aspnet.web.optimization

Anyone that stumbles across this question here in the future should know that there are now Shared Projects in Visual Studio to solve this problem. Universal Windows projects use them by default and you can create your own by downloading and installing the VS extension here: https://visualstudiogallery.msdn.microsoft.com/315c13a7-2787-4f57-bdf7-adae6ed54450
Once you download the extension you can add a Shared Project (Empty) to your solution. The project can be found in the project templates for Visual C#, Visual C++, and JavaScript.
Then include the files you want to share to the shared project in any folder structure that makes sense for you.
Next you will include the shared project as a shared reference in the other projects in that solution that need access to the shared files. Right-click the other project and choose "Add Shared Project Reference".
Now you can reference the shared files in your main project as if the files in the shared project existed there. They are compiled as part of that project.
The technology was intended for Universal apps to share code between Windows Phone and Windows Store apps so be warned that you may have trouble sharing in different scenarios but it is worth a try to see if it will fill your need.

You could perhaps use visual studio templates

great question, I've been thinking about this for quite some time. The only solutions that have popped up in my mind are hosting the files on the web and using them like a cdn or using symlinks. You could add a code snippet into your visual studio to reference them.

This blog post describes an alternative solution to the answer by #beardtwizzle:
http://consultingblogs.emc.com/jamesdawson/archive/2008/06/03/using-linked-files-with-web-application-projects.aspx
The idea is similar:
Add the shared file to to web project as a link
Modify the _CopyWebApplication build step in the project, so that the linked files are copied correct destination path.
So instead of a post build event the files are copied by a modified build step. For me this solution feels a little bit cleaner (but this may well be a matter of taste). Anyway I just added this to our solution and it works great so far!

Use proper version control.
Keep the js in one location and then just git pull (or the equivelant Mercurial / Bazaar) them back into your code whenever you've updated your javascript.
