I'm a few months into web development so I apologize if I misunderstood anything.
What I did
I created a react-random-shapes package that would draw out random shapes as a React component. You can see an example here on my site or in the project page. Each time you refresh the page you'd get a new image. (Note: these pages use React.)
What I want to do next
The result I'm aiming for is to create an API (GET-only) on GitHub Pages that would return the dynamically generated svg file (so you can do something like
<img src="https://github.com/artt/react-random-shapes/blob?size=300&fill=red">
which would return a random blob for anyone who's interested in using. Alternatively, this API could return the svg path so the user could do whatever they want with it (e.g. animation).
The problem I have
Right now I know how to output an html page with the svg file, but not quite sure how to return just the svg (or json, etc.) part of it.
Thanks!
I am trying to do the same thing. I think your best bet would be to use a webserver on another platform like Heroku or, another good option, Replit.

so I have this website made with Next and on a page there are some graphs (the graphs content changes as it fetches an API) and info.
I want to add a button to the page and when pressed it download the page as a HTML file and includes all the JS and CSS in the HTML file instead of separately, does anyone have any idea as to how to approach this problem. (The graphs content should be the same content as it was on the time of downloading)
(The reason why I want to do this is because I want to distribute these files to others and I want to allow them to read it w/o an internet connection)
You can't really download a React 'page' because there are no pages in React to download.
Next further complicates this because it server-side renders everything and rehydrates client-side. If you inspect one of your pages, you'll see the JSON blocks Next uses for data. Look for the __NEXT_DATA__ script (usually in the footer of your page).
I think the two strategies you could use:
Screen-capture of the graphs during your build sequence and push them over to an AWS S3 bucket or similar (cumbersome)
When I ran into a requirement like this, I just made the data for the graph available as a JSON download just below the graph and it satisfied the use case sufficiently.
If you just want to download the assets and take a look, a workaround is probably leveraging the next/export package. This allows you to run yarn build and generate a static export of your entire site. This should include the file you're looking for.
Just some ideas to think through.
I'm creating a gallery of images in ReactJs. There are a lot of examples online, but i didn't find anything that is perfectly responsive on desktop browsers and also completely mobile friendly.
In particular, when an image is opened on the mobile browser, i need to be able to zoom the photo with a double tap, and close the photo when i drag it to the bottom
I already tried all the principal solution that i found online.
For example, i tried all of these https://reactjsexample.com/tag/lightbox/
and much much more.
I also tried different approaches like CSS rules, Viewport rules, create a simple zoomable html div, etc... But nothing worked.
Basically, what i what to achieve is exactly something like this: https://www.lucapetruzzi.com/gallery/1
Created thanks to this library: https://photoswipe.com/ that unfortunately i can't use in React.
(I also tried the react-photoswipe and react-photoswipe-2 libraries but it seems not maintained and not working with new versions of React)
Thank you for any help
So for previous comments, I wrote a snippet for you, check here
Here are the mainly steps:
use npm install photoswipe so DON'T need to include builded js but NEED to include css in index.html (or you can import in App.css)
write the markup in js component
init it by click button or in useEffect
Based on my custom URL parameters I process, I am trying to modify dynamically a meta tag I have id'ed in index.html like so:
<meta name="og:image" content="http://example.com/someurl.jpg" id="ogImage"/>
The code below in my home.ts seems to be working
document.getElementById('ogImage').setAttribute("content", Media.ImageURL) ;
I can verify it is via the browser dev console/elements.
However, when I view from facebook via their ojbect graph debugger at
https://developers.facebook.com/tools/debug/og/object/
It appears to see the default
http://example.com/someurl.jpg
as if the index.html is shipped before my home.ts gets chance to make the update.
Perhaps, my understanding is flawed and there is better way to do this.
Thank you.
Note1: initially, I was thinking I had to make some angular binding between index.html and one of my services but I could not locate any sample code, the closest I came to was this post
How can I update meta tags in AngularJS?
But I don't know how to apply it for my ionic2/3 code, so I opted for the document.get approach.
Note2: the ultimate goal here is to share a link into a social media (web or app) like facebook, a messenger like viber/skype, etc... and have it resolve to meaningful images, title, description to drive the visit back to the site via browser, or app if the user clicking on the link is on a mobile device with my app version of the site installed on his device.
Note3: if you decide to point me to ionic deeplinking please provide code to match above, because I could not understand how to apply to my case.
If you are trying to implement dynamic open graph meta tags values in your pages, you will need a server-side scripting language like php. Such a script will run on the server, update the pages as needed, then the pages will be served to the requesting site or application.
client-side scripting (ie. JavaScript) is usually ignored when a site or app is merely visiting your site/link for the purpose of extracting (aka scrapping, parsing html) information such as the one provided by the open graph meta tags (og:title, og:description og:image...).
I am currently working on a website and during the loading of the entire page, the page is "jumping" so that I would like to know how I can create an entire ,let's say black screen, where something is displayed during the time the page loads.
That seems quite easy but I was wondering because I have separate files for the header, the footer and the content on how to coordinate all of them, and still have a nice code.
I am working with angularJS. I read a lot about : $viewContentLoaded and also tried ng-cloak, but if any of you has an awesome solution to keep simple, it would be great :)
Thanks
I would say that one approach you can take is use some sort of templating engine for your HTML files (like Jade for example). In this way, you can keep all the code nicely separated in multiple files and using a task runner like Gulp or Grunt you can compile your HTML files before serving the page.
The important difference here is the fact that you won't have to load all the page parts (header, footer and so on) using AJAX requests. Instead, they will already be rendered in your HTML page allowing you to create a nice loader using ng-cloak on your content part.
Hello we have a non profit application built in Google App Engine for Java.
This application allows people to register as Blood Donors on our system.
As a result we want to email them their print ready e-BloodDonor cards.
What is the way to create such cards where we can define the design of the card and contents are filled dynamically based on registered data?
Please advise
You could create the layout in HTML, just like a normal view in your app, and then email them the link to that page to print it out. You could also go the much-more-complex route of generating PDFs or images for each user. PDFBox by Apache is pretty good for PDF generation.
I'd really recommend the HTML route, though, if it works for you. In my experience, it's much easier to do HTML layouts than it is to program PDF layouts in Java.
