I am trying to get more familiar with the WebDev module and trying to understand some of the use cases for it. I don't have any requirements to send data to ignition but I was wondering what other use cases you are using it for? In the advanced perspective class, we used it to save images to a database and then pull from the database to be displayed on a screen. Not sure if that was a best practice or just an example of what it can be used for. If you don't mind sharing, what else are you using it for? thanks! ---

I have not implemented it yet, but I hope to use it to allow tools like PowerBI to pull data from the gateway making use of its system.tag.queryTagHistory() function. ---

I've only used it so far to mount a folder. A script reads from the mounted folder and supplies a list of PDF files that can be selected for use in a PDF Viewer Component. ---

Back before Perspective, we used it to allow us to have a web based front end dashboard. I have also used it to scrape data from third party device web UI's (e.g. a device which only has a private web interface), where I didn't have a means to connect via some other means. ---

I've had several use cases for the WebDev Module: --Endpoints for other applications/systems to send data or read data from Ignition. ---Example: ERP system sends data dumps daily -- Custom JS/HTML/etc functionality as an example we tried out a document viewing application which had 3d model viewing so we could use this to view CAD/STL/files. (Performance was hit really hard using this so we didn't end up using this for production. -- Another custom JS tool we tried to add was cytoscape: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/8/c8ab23429e907371b3e67acacbff95a908b4e1a2.png) Imagine the above except each block is a cell on a line and instead of a network diagram it's more of a full plant floor process with a plant floor diagram as the background. It allowed users to pretty much build and place their process then save the config to a db. You can get pretty creative with it and it has many helpful use cases. ---

that's pretty cool, thanks!
