Is it possible to run a Node.js file from the serverside from JavaScript? If so how would i? I have googled some but cant find a real answer to this. Thanks

NodeJS is JavaScript on the server-side environment.

What you refer as "JavaScript" is actually the same JavaScript, just in your browser environment.

What you can do: you can use Webpack to create a NodeJS app, that will automatically create an index.html and put it on a server. With webpack, you can also import NodeJS modules in your frontend code.

For example:

main.js:

import './index.html';
import $ from 'jquery';

$(() => {
    console.log('jquery is ready');
    $('#root').append('<h2>How are you doing?</h2>');
});

index.html:

<html>
    <head>
    </head>
    <body>
        <div id="root"></div>
        <script src="bundle.js"></script>
    </body>
</html>

The bundle.js will be generated by Webpack.

JavaScript modules, Node.js has had this ability for a long time, and there are a number of is that modern browsers have started to support module functionality natively, versus using .js for "normal" JavaScript files, but don't want to run into the  Being able to call Node.js modules from JavaScript running on the browser can present many benefits because you can exploit the Node.js modules for your client side JavaScript applications without having to use a server with Node.js just because you need to implement a functionality that's already available as a Node.js module.

If this file uses nodejs API like Streams, HTTP, File System etc, it is impossible, cause browser is not able to run these API.

Using and Running Node.js Modules in The Browser, In this quick tutorial, we'll learn to use and run Node.js modules in the written with the Node.js modular system to classic javascript file that  Types of Node.js applications. Node.js is a JavaScript runtime primarily used for creating web applications. Put another way, it's a server-side implementation of JavaScript used for writing the backend of an application. (Though many Node.js frameworks can also handle the frontend.) Here are a few examples of what you might create with Node.js.

there are some basic differences between browser js env and node server env. Example: WEB API is availble for browser js env for node its different.

Moreover node ecosystem has alot more support for several other functinalities like file system handling etc.

Since node is developed for server side programming,you should pay proper respect to the purpose and not try to run it in browser :)

How To Create a Node.js Module, In Node.js, a module is a collection of JavaScript functions and objects that can be Start the Node.js REPL in the same folder as the index.js file: runtime environment that can execute JavaScript outside of the browser. Node.js files must be initiated in the "Command Line Interface" program of your computer. How to open the command line interface on your computer depends on the operating system. For Windows users, press the start button and look for "Command Prompt", or simply write "cmd" in the search field. Navigate to the folder that contains the file

Node.js Modules, Node.js? Consider modules to be the same as JavaScript libraries. Now you can include and use the module in any of your Node.js files. Run example ». It ensures that your module files are parsed as a module by runtimes such as Node.js, and build tools such as Babel. However, we decided to keep to using .js , at least for the moment. To get modules to work correctly in a browser, you need to make sure that your server is serving them with a Content-Type header that contains a JavaScript MIME type such as text/javascript .

Modules, introduction, How do I open a node js file in my browser? Notice that we use ./ to locate the module, that means that the module is located in the same folder as the Node.js file. Save the code above in a file called "demo_module.js", and initiate the file: Initiate demo_module.js: C:\Users\ Your Name >node demo_module.js. If you have followed the same steps on your computer, you will see the same

What is this Javascript "require"?, , that's tunable), replacing native import calls with bundler functions, so that it works. I'm building a project that is intended to be ran locally (both the Node server-side part and client-side in the browser), where I'd like to be able to select a path, add it to some list or JSON file, and then maintain some projects in it (webpack'ing, read files, serve via express, etc). Mostly just for personal use, for now anyways.

  • Can you add more details about the file you want to run? What are you trying to accomplish? Typically code written for the client side is built using something like webpack.
  • Only if there's a process that's listening on the server for the specific requests and that has the capability to run said file.
  • @Chris I want to run a node.js file that contains a csv writer, just a promise that runs once
  • And that csv writer returns a string? As mentioned in the answers, it'll work so long as you don't use certain node features unavailable in the browser. You should give more detail about your running environment/app so people can advise you on how to work the module in.
