I have a JSON file generated using the "Record" option in the dev tools. Is there a way (or tool) to consume that JSON and perform the same actions by adding a new step to take a screenshot instead of writing the whole code?

I have a JSON file that is used in a monitoring software for monitor an specific device.
I want to monitor a similar device which I don't have the JSON file.
I know everything from the new device that is needed to "fill the blanks" in the existent JSON structure.
A brute force approach would be create a script that reads the data (of new device) from a craft input file and output the nodes and leafs in the same JSON structure.
Before I take this path I would like to know if there is some tool that could help me in this task. For sure this "wheel" is not new, I don't want to re-invent it again.
Anyone knows about a tool that uses a JSON as template and generate another one changing the values from other source ?
I am on linux, can write scripts in bash and python.
I am working on a GUI (PyQt6) where the user loads some files and adds metadata for each. So for each file, I would like to have a window (QDialog) which is essentially a form with fields which are specified by a json schema.
I am new to PyQt and I can code the mechanism to open a form (QDialog with QLabels and QLineEdit which essentially looks like a form. see image). However, I would like to automatize this step using the schema that's stored in a json file (consider any example json schema).
Is there already a python library for this and I'm absolutely obvious about it?
How would you go about coding this? Thanks!
I would like to visualize data from csv file at node-red ui.
What I would like to do is to show behind a flag of a country the countity from the csv file. So into the csv file I have 2 columns (country, quantity).
Because of I am new at node-red I would like to get some hints how to do that.
Thanks in advance.
my flow with CSV data
Welcome to Node-RED!
Firstly you need to decide what kind of UI you would like. Node-RED has options for a number ranging from the creation of data driven web pages using the http-in/out and template nodes through the more dynamic but slightly more complex Dashboard through to full-power dynamic web-apps using things like node-red-contrib-uibuilder.
The very simplest approach is to use an http-in and an http-out node to define a web page. Then to add your file reader after the http-in then the CSV node (which turns the CSV data into JSON). Then you could use node-red-contrib-tableify to turn your JSON into an HTML table. Finally use the template node to insert the table into the html that the http-out node sends back to the browser.
http-in -> file read -> csv -> tablify -> template -> http-out
Once you've mastered that, you could go on either to smarten up the template or swap to using Dashboard or even uibuilder depending on your needs.
I have to create a web page first, right?
You define the URL in the http-in node. When the -in is connected to the -out, you have a "page". Albeit with no content. To create content you can use the template node. In fact, pushing the csv data through the tablify node and into the template would give you enough of a page to see the data. The templatate itself need only be:
<pre>{{payload}}</pre>
Though, of course, you can also wrap that with other HTML elements as needed. But that alone should be enough to render something useful.
How can I trigger the http-in?
You simply reference the URL from your browser. So if you set the http-in node to use URL /fred and you used a browser on the same device that is running Node-RED, you would use the URL http://localhost:1880/fred in your browser.
How should I design the web page to be able to put the information from the csv file into it by the http-out node?
The tablify node does that for you.
String together what I've outlined and you should see something that will let you go further.
I suggest just using http-in, template and http-out nodes to start so that you can see how they work together. Then feed in your data without the csv or tablify nodes, then add the csv and finally the tablify. That way you can see how things work.
There's an online tool that I'd like to tweak. It depends upon a JSON file. The easiest way for me to make the changes that I desire is to edit this JSON file directly, which I'm doing using the "Edit text" feature of Chrome DevTools. Next, I need to reload the main webpage so that it fetches the edited JSON file. Of course, this doesn't work because the webpage fetches the resource from the server. Is there any way to make the webpage temporarily load my edited JSON file?
I've been trying to find the documentation for populating a DAG instance using JSON. Is there formal documentation to the format somewhere?
JSON application spec is available under http://apex.apache.org/docs/apex/application_development/#json-file-dag-specification
At the current moment JSON application creation is enabled with dtAssemble, a beta feature of DataTorrent RTS. The documentation for using dtAssemble to create JSON apps is available under http://docs.datatorrent.com/dtassemble/
You can experiment with dtAssemble, and inspect the PUT operations of /ws/v2/appPackages/[user]/[package]/[version]/applications/[application] service call to see the JSON structure generated for the application you're building. You can also download the application package where the app is being saved, unzip it, and inspect app/*.json files added there.
