Are there any complete examples of how noflo can be embedded in a webpage, including the hookup between noflo and the webpage UI components.
For example, a simple noflo graph for;
Date input for date of birth, using datepicker UI on the webpage.
Output of age in years and days, using text label on the webpage.
How could this simple example be created as a noflo graph and then embedded in a webpage.
I'm looking for a complete example that can illustrate the approach, which I can then explore extending.
Thanks for any help.
The easiest way would be to use either noflo.asCallback (for single-run "batch processing" style graphs) or noflo-wrapper (for continuously running graphs).

I'm working on a React Native app, and I'd like to create a function for sharing contents in Instagram stories, like the tweet below.
How can I generate a custom template, like Twitter does, using Python? Because my backend is written in Django.
=== UPDATE ===
I have done some research and found out that you can use various languages, such as FabricJs or PIL in Python, to draw an image. However, these can be a nightmare for high-complexity stickers. Therefore, my solution is to simply take a screenshot in the app using react-native-view-shot.
If someone has any better solutions, they would be greatly appreciated.
Thank you.
Websites previews based on website meta tags like open graph
You can use this library to generate it https://github.com/tjcages/expo-link-preview.
However, it maybe a better solution is to build these previous on the backend like here https://github.blog/2021-06-22-framework-building-open-graph-images/
And then share image with https://github.com/react-native-share/react-native-share
Creating Modified Blog Entries
I am new to React, and very much to Docusaurus, however, I've managed to get a decent looking DS site going. I am trying to capture some simple snippets to as "blog entries", just small factual snippets, etc. simple project summaries. I’ve hit the limit of the Docusaurus.config options and not sure how to expand the out of box components.
How do I begin to alter and edit Docusaurus to change the Blog page to be like "Cards" in component-speak? Ive seen some example in Infima, but not sure how to bridge that gap?
How can I easily replicate the Announcement Bar to also be at the bottom, like a Banner?
Thank You!
One possible arena for you to use is Bootstrap — specifically React-Bootstrap. They have a card component you could use where you link individual blog entries to that card. If you're comfortable with JavaScript, there's probably an automation you can build there, but hand-coded text is somewhat part and parcel with static-site generators.
If you want a different solution with the CSS code in your src file outright, CSSCodeLab has a React Card layout entry with an attached source code file. Some hand-coded text required, and not automatically integrated with a separate blog setup, but YMMV.
Otherwise Docusaurus' Showcase page does provide the card formatting. The source code for the page (coded at index.tsx) as well as the components are available.
My current project setup
Angular js 1.5
integrated fusion chart https://www.fusioncharts.com/fusioncharts
now am trying protractor framework to automate the application and i could do many things like form validation , input and submit .
Now i have problem with Fusion chart automation , like am not able to validate the data that showing on the graph is correct or not .
i tried below idea but am not able to get reference it giving error fusion chart is not defined .
outine
please comment on the below idea and suggest any other way to automate this or any other new framework .
You can write test cases using FusionCharts life cycle events supported to test but please note chart need to be rendered first on any browser as FusionCharts is a JavaScript charting library that you need to include in your HTML page/application to use or run the charts.
Fusioncharts has its own supported events and methods which you can use like method getCSVData to fetch chart data set in the CSV format which you can later validate if its correct or not as per your requirement.
Refer below doc link for lifecycle Events using AngularJs,
https://www.fusioncharts.com/dev/getting-started/angular/angularjs/lifecycle-event-using-angularjs
Please refer below doc link for all supported methods with details and samples,

Please refer below doc link for supported events,

Hope this helps.
The jQuery VideoControl is documented here:
https://developers.google.com/tv/web/lib/jquery/#gtv.jq.VideoControl
It takes a set of VideoParms. That are not specified.
It is used in the sample templates on this page:
https://developers.google.com/tv/web/docs/gtv-templates
I've taken apart the templates, but I'm having difficulty creating a simple example of a standalone video control. In the templates, the sidenav and carousel code are tied to how the videocontrol works. There is a relationship between the keyController and behavior (behaviorZones) that I can not find an explanation for.
Is there a standalone example somewhere? What needs to be setup with keycontroller, css, and behavior to get this going?
I'm not aware that there is a standalone videocontrol.js sample but it should be possible to set it up. Most of the necessary pieces are inside videocontrol.js, in particular in the videocontrol's constructor and this function: gtv.jq.VideoControl.prototype.makeControl.
keycontroller mapping is used to handling key inputs and some of the CSS are dynamically controlled within JS so there might be errors if you just rip them apart straight from the Template. You'd have to debug it using a solid tool like Chrome Developer Tools. You can watch tutorials of this tool here: http://www.youtube.com/results?search_query=chrome+developer+tools&oq=chrome+develop&aq=0&aqi=g3g-m2&aql=&gs_sm=3&gs_upl=1972l4015l0l6142l14l11l0l0l0l0l207l1476l3.5.3l11l0
Otherwise please send your error traces and/or code snippet for debugging help.

Trying to get access to a page's DOM after rendering. I do not need to view the page and plan to apply this programmatically without any GUI or interaction.
The reason I am interested in post-rendering is that I want to know where objects appear. Some location information is coded in the HTML (e.g., via offsetLeft), but much is not. Also, Javascript can change the ultimate positioning. I want positions that are as close to what the user will see as possible.
I've looked into Chromium code and think there is a way to do this but there is not enough documentation to get started.
Putting it VERY simply I'd be interested in pseudo-code like this:
DOMRoot *r = new Page("http://stackoverflow.com")->getDom();
Any tips on starting points?
You should use the Web API wrapper that Chromium exposes; specifically, the WebDocument class contains the functionality that you need. You can call it like this:
WebFrame * mainFrame = webView->mainFrame();
WebDocument document = mainFrame->document();
WebElement docElement = document->docElement();
// Manipulate the DOM here using docElement
...
You can browse the source code for Chromium's Web API wrapper here. Although there's not much in the way of documentation, the header files are fairly well-commented and you can browse Chrome's source code to see the API in action.
It's difficult to get started using Chromium. I recommend looking at the test_shell application. Also, a framework like the Chromium Embedded Framework (CEF) simplifies the process of embedding Chromium in your application; I use CEF in my current project and I'm very satisfied with it.
