HTTP Handler for TCP Server designed for Wolfram Kernel (Mathematica, Engine)
Via Wolfram Paclet system

There is a set of usefull example, that helps to understand the logic of a webserver and its applications
This basically replicates the functionalify of Wolfram APIFunction
available in Cloud only. However, using our approach one can run it locally
wolframscript -f Examples/APIFunction.wls
then open your browser at
http://127.0.0.1:8000/cellular?rule=69&step=500
http://127.0.0.1:8000/bars?v=1,2,3,4,5,6
what it does, it provides the URL parameters to the defined API function and generates the result for the reply
This is a simple example of templating using StringTemplate
to embed the data into an html document from the request parameters or call an arbitary Wolfram Language function
wolframscript -f Examples/StaticWebsite.wls
It also shows how to work with media files and paths for the server. Those two WL logos are requested from two different folders, specified in Base
parameters as an array of paths. Also the current date and a list with request parameters shows how to embed the WL function into the document.
A bit more advanced example - a follow up to APIFunction
- that unleash to power of modern HTML/CSS stack and POST method. It relies on Wolfram Script Pages framework for easier templating bringing simillar experiense if you was writting in PHP
wolframscript -f Examples/FormExample.wls
One can design anything in any share, using its favourite JS/CSS framework. Here Bootstrap is used. It has almost no limitations, when it comes to the static content generation compared to Wolfram Cloud
Each time you drag a slider and click to Submit
button, it sends POST request, recalculates a new plot and sends to a user. No JS required, just old good HTTP and reqular forms processing.
This is a demonstartion of how to work with POST request. It can process only text files and text data unfortonately. When you upload the data and submit it, it redirects to the specified page, while the recived data is printed to the console
wolframscript -f Examples/POST.wls
This demo shows on how to work with WSP (Wolfram Script Pages) template engine and generate content based on user's request passed via URL parameters
wolframscript -f Examples/WSP.wls
index.wsp
<?wsp With[{color = $CurrentRequest["Query", "color"]}, ?>
<div style="width:100px; height:100px; background-color: <?wsp color ?>"></div>
<?wsp ] ?>
As one can see, it puts a color variable into the style of a div
element. Then if one open a page at
http://127.0.0.1:8000/?color=cyan
it will show
This features a file explorer & graph viewer made out of independent components simillar to what people do in a modern WEB
wolframscript -f Examples/Plotter.wls
One can navigate through the folders
and open the sample data
For each file there is a view.wsp
component that generates SVG image and embeds it into a page.
Cool, ha? Thinking about what you can do, makes Wolfram Cloud to be just a toy for the rich kids - @JerryI
One could go even further utulizing the power of WebSockets and WLJS (a tiny Wolfram Language Interpreter running in a browser). So that we do not need to spend resources on generating ugly static SVGs, but providing just the raw data and make browser and Javascript to do the actual plotting
wolframscript -f Examples/Plotter2.wls
The naviagtion is the same, but when a user opens a file it shows a placeholde, while Javascript is pumping the data from the server via WebSockets (aka hydrate the HTML element) and then plots the received data
This is not about rocket science, but a combination of a few simple open-source tools, that moves Wolram Language beyong the notebook interface
