I'm working on a twitch.tv overlay that generates a word cloud live on-screen based on what I've been saying on stream.
I'm currently using Visual Studio Code with Live Server to display a file via an HTML file alongside a Python script that generates a new png file of the word cloud, using the same filename.
Using the Live Server extension is nice, but I can't help but feel like it's sort of a dirty solution. Any ideas on something more formal?
NodeJs and Express could be a good option. The server could be written in Javascript and you could use a sub-process to call your python script on an interval.

I have a html file that when run in a browser such as Chrome and that contain javascript instructions, it sends the "emit" message to my websockets server and displays the value on that page.
Is there a way to call this same html file from a bash script as I'm wanting to insert data into a MySQL database which will ultimately call that html file to send an update to the websocket.
Hopefully that makes sense but hopefully there is a way to do it too :)
If you are only focused on rendering the HTML page (and not interacting with it via buttons or something) you may find this link helpful: Running HTML from Command Line
If you try to execute javascript instruction in your server without using a browser, I recommand you to use Node.JS with a real js script without html.
Otherwise you can try to run an html file with js instruction inside using something like phantomjs but I think is less performant than using Node correctly.
EDIT
It is Javascript yes, but I need to "Import" the socket.io.js file into the same script I have created and my browser I'm having to use doesn't support the new Javascript import methods. So I'm writing as HTML which calls the Javascript, otherwise I would use nodejs
I think you can import the socket.io lib in node application using npm.
https://www.npmjs.com/package/socket.io
The documentation says that you can use a client inside a node script too :
Socket.IO enables real-time bidirectional event-based communication. It consists in:
a Node.js server (this repository)
a Javascript client library for the browser (or a Node.js client)
Is there a way to replace a .js file in the website sources with a file on my workstation, or make a modification to a .js file and refresh the website to see the changes?
I am developing client-side JavaScript code against a SharePoint website on a server. I cannot create a local version of the website, so I need to modify the script, save the file to the server, refresh, etc. I do not have direct access to the server, and saving a file in a SP doc library or web part takes a lot of time between edits.
I can make small modifications using the dev tools while breaking on certain lines and applying snippets, but I am hoping for a better way.
Thanks!
If you have access the server that's hosting the file you should be able to replace or modify the JS file. Alternately you can use local hosting tools to test your file and then upload it to the server once you've confirmed it's working.
If you explain what you level of access to your host is we can offer better suggestions.
Is it possible to send a images to the Pebble watch using PebbleKit Javascript sendAppMessage.
My idea is to load an image from the web and send it to the watch and display them there. If an image is not possible directly then I was thinking of drawing the image to a canvas and trying to get bitmap data from the canvas to send to the watch.
Is any of this possible now or am I thinking of things that have not been done yet. If possible how? If not done yet how might you do it?
Looking to brainstorm and share possible code ideas.
I should also mention that I do not want to use an iOS or Android app, only the PebbleKit JS.
There is a complete example of an app that uses JavaScript to download images in the pebble-hacks Github repository. This github projects hosts different non-official yet written by team pebble.
The one you are looking for is pebble-faces. The image download part is built in a separate source file to be easily re-used in your own project.
I also added a PHP port for the Python script here
https://github.com/logbon72/pebblebitmap
It might come in handy if your run PHP applications that need to do conversion on the fly.
So I have this html page. Inside of it is a bit of javascript code that talks to a flash application.
During the flash application's lifecycle, it'll save a file to a place on the server using the javascript on the html page.
How can I use javascript to take the file I just saved and move it to a different location?
You cannot. Javascript works on a client and don't have an access to the server's filesystem.
You can only trigger a script on the server that does that.
As you said you have node js installed and running on the server,it is possible for you to move a file using the nodejs filesystem api: http://nodejs.org/api/fs.html#fs_fs_rename_oldpath_newpath_callback
For this to work you would need to monitor and detect when new files are saved in a certain folder, which should be possible using: http://nodejs.org/api/fs.html#fs_fs_watch_filename_options_listener
Happy coding!
I was wondering I have PHP based server side stuff that accepts ajax requests and sends back JSON for JS. And I have HTML and JS based "client" now I would like to create exe(windows aplication) that would look the same as the "client" in browser but without browser. Preferably somehow grab that HTML and JS and "compile it" to regural client that would still send out AJAX calls and procesing JSON data.
Edit:
To clarify things:
Server(on webserver) is PHP procesing incoming AJAX calls and diplaing JSON as result.
Client(what I want to convertt to exe) is HTML and JS(Jquery) page(application).
I want for user to have option two to dowload client for windows so he/she dont have to use browser.
With https://electron.atom.io/ from Github you can develop Windows, Mac and Linux applications with Javascript, Html and CSS. You can also build mobile application with your web development skills. https://cordova.apache.org/.
You can use Electron, but if you just want something quick and easy to use, try Scriptonit. It's exactly for this kind of use. (Check out the documentation and the examples to see if this is the one for you.)
It's basically one exe plus a few sidecar files in a folder called app/, then it just works like a local browser without the frames & head. Also, it can access local files and run OS commands, even capture their output.
Side note 1: Yes it's mine, as you can see on the link - but no, that's not why I'm recommending it
Side note 2: It's 0.9 so it's not perfect, let me know if it misbehaves.
I don't think you can make a desktop application with markup languages. but then am also a newbie in this stuff but what I think you need is to develop a GUI in a programming language like java for example Swing docs.oracle.com/javase/tutorial/uiswing/ to mimic the apearance of your webpage. Then connect to your server by socket programming.
