QUESTION
I'm running NodeJS for my server-side javascripting, but serving my pages with Apache.
My pages currently reference Socket.IO locally, in that they load the node_modules/socket.io-client/dist/socket.io.js from the /var/www/html
The NodeJS index.js file also resides in /var/www/html which has become a problem for me.
Can I move my NodeJS index.js file to var/www so it is no longer publicly accessible, without needing to move node_modules from var/www/html which Socket.IO is relying on to be publicly accessible?
ANSWER
Answered 2020-Oct-11 at 15:33When using Node.js to serve the Webpage:
Your servers root directory is typically not publicly visible. Requests to your server get handled by the routes you set up in the index.js file. By default, no files are accessible. However, if you need a public folder (e.g. for the favicon file or an index.html file), I would recommend creating a subfolder in your root directory and use for example express to make it available.
When not using Node.js to serve the Webpage:
If you need Node.js for client-side logic, you should just use normal javascript (for example this in the case of WebSockets). Node.js is a serverside application where you run javascript on the server. So on the client-side, there is no need for Node.js. If you need certain npm packages, SubStack on GitHub has a module called node-browserify. It will compress and bundle your modules and deliver it as a single js file, but you use it just like Node.js.
If you need Node.js for server-side logic, then there is no need to make it publicly available and you should change your current server configuration to not make it accessible from the browser.

So I'm working on a website, integrated the iframe of a soundcloud playlist and tried to adjust the volume. I looked at the general values of the iframe, saw that there was no value for volume. I proceeded to check how it could be done otherwise. Looked at several posts on stackoverflow, found a "solution" with the soundcloud-api. I did the javascripting, still didn't work. Looked more, found more. But every solution I found just didn't set the volume. The steps I performed: Get the SoundCloudAPI
...ANSWER
Answered 2018-Sep-09 at 19:03You can't use setVolume on the widget player, you need to be using the SoundCloud JavaScript SDK. Set up your track using the JS SDK instead of the widget.

QUESTION
I am new to JavaScripting and Node and am putting a proof of concept together for my first application. My goal is to:
- Parse a CSV file (since the data I want is way to small to warrant a database)
- Load the parsed data into an Array
- Search the Array for a specific 'Date' which will have two other fields I can pull data from
- Present that data as an exported function (please forgive my phrasing if inaccurate)
With help from a previous co-worker, I found PapaParse and lodash to help with parsing the data and searching it. The application works great if I call the function in the same application. When I try to export the function I get no results. I have been trying to solve this problem on my own for two weeks now and am hopeful someone can help me.
ANSWER
Answered 2018-Aug-01 at 08:50I think what @MukeshSharma is trying to say is: Since your function is asynchronous, you have to provide a callback-function when calling the flavorOfTheDay()-function. Just like you did in the first code snippet: flavorOfTheDay('07-12-2018', doStuff) --> the doStuff is your callback function.
Modified example from above as anonymous callback function:
QUESTION
I have a frontend-only web application on Netlify which has to consume an API on OpenSubtitles.org. Although OpenSubtitles.org enables CORS, sometimes I got preflight errors, so I decided to use a proxy.
I had problems using Netlify's proxy feature, so I decided I will create my own proxy on Heroku, and send my requests from the frontend to there, so these will be proxied to OpenSubtitles.org from a server.
I came up with the following based on the code I found here:
...ANSWER
Answered 2018-Jul-13 at 02:40CORS is working because the url you're requesting responds with the header Access-Control-Allow-Origin set with a value of *. Since you're piping that response and its headers back to the original res object, it will enable CORS as if it was coming from your local proxy.
Below is a more straightforward example of how to proxy a request to another site and return its response intact using node streams.
