I recently came across a use-case where I need to measure the components dimensions on runtime. On exploring the solutions I found a tutorial which uses a built in method called findNodeHandle. To be precise it was getting used as first argument of measureLayout method.
I tried exploring the use of findNodeHandle but could not find anything.
Can anyone please guide me a little bit on what exactly findNodeHandle does in react.

I'm using highcharts, the Venn module (highcharts/modules/venn.js), and using the highcharts-react-official package to support it in React, the need to show the Venn diagram circles as shown here:
This is what I have now:
However, I tried to figure out away to do this using legand.layout but did not manage to modify the alignment to get the that results, here's what I get.
Any Idea how to do so, if providing the code for that would help more, I'll be happy to share, but I thing either there's an API that I'm no able to find, or its not supported and I have either to find another solution or find a workaround
Really appreciate your time & help
I wanted to create a react project allowing a user to annotate floorplan thanks to Go.js's floorplanner here is the link https://gojs.net/latest/projects/floorplanner/FloorPlanner.html. If you look visit that link and down below you will see the scripts that were used to create floorplanner. But instead of creating the floorplanner with vanilla JS I wanted to use React.js. Can someone help with the integration of Go.js's floorplanner with React?
This question is too vague for an easy answer. You should look at the react example: https://github.com/NorthwoodsSoftware/gojs-react
And modify it to your liking. This can involve taking large parts of all of the floor planner sample, though if you have no practice with GoJS this it may be worth taking the time to learn everything involved in the sample, before any integration.
For the past couple of months i've been learning how to code through looking at videos following along reading documentations and generally fiddling around.
I've been stuck countless amount of times trying to understand one simple thing after another, until I got fairly adapt at solving my own problems through quick google searches, recollection and repeating the same task.
But what i found the most beneficial to my learning was looking at other people's code and then trying to understand how it works, more specifically whenever there is a function i dont understand i look at a application online and see how the function is used and what the end result is the problem is I can't seem to find a fitting application for learning how to use populate() and aggregate().
I'l be honest, I never learned very well through just reading something and then understanding it, I only ever learn well when I myself am actively doing it and seeing the results for myself.
This is why i am asking you all in this wonder community if you know a application that actively uses populate() or aggregate() or makes it the main focus.
What i want to understand is how to use these two functions and when to use them, because while I understand their concept and what they are used for, in practice I just can't seem to understand at all.
Furthermore I am confused on where they are exactly used as well, I've only dabbled in react, mongoose and other generally associated npms to do with website making.
Please help.
I've recently started using react and so far I'm enjoying it a lot.
However I'm struggling with the documentation.
I've seen some mentions of unstable_renderSubtreeIntoContainer / renderSubtreeIntoContainer mentioned here (github).
In which context would I use this? How would I use it?
Thanks a lot in advance!
One of the use cases is "portals" - when you need to render a component outside the react app, but still control it as usual.
For example - https://github.com/tajo/react-portal/blob/master/lib/portal.js#L135
I am trying to learn backbone, however truth be told, I'm feeling a little overwhelmed. Everywhere I look it is being done in a slightly different way, each with more frameworks and plugins to learn. So I have decided to put my faith in Addy Osmani and am reading his Backbone Fundamentals book. I have followed his recommendation and used the Backbone-Boilerplate. However for whatever reason, I have been unable to successfully install Grunt BBB so I cannot download the working examples.
What I am trying to do is follow this router section and use views. http://addyosmani.github.com/backbone-fundamentals/#router.js.
The problem is that I think these instructions are incomplete. For a start the collection.fetch() variable is in the wrong scope, and I really am not understanding where I need to place the views and how. I am pretty sure that if I could see a working example of this I could understand it, but as I said, everywhere I look its a different implementation.
Does anyone know how to use the backbone-boilerplate with routers and views? Are there any working examples anywhere?
Let me make a suggestion. A couple of months ago, I was where you are now: trying to learn backbone and trying to follow best practices while I did so. Like you, I came across Addy Osmani's book and like you I tried getting stated with backbone-boilerplate.
After much stumbling around, I eventually concluded that backbone-boilerplate was not something I needed to have while I was just learning backbone. It is now, only after having created a fully working, non-trivial CRUD application that I start to see how I might incorporate backbone-boilerplate. I think you probably need to be asking the questions that backbone-boilerplate answers (How can I break up my application into modules?, etc.) before you attempt to incorporate another framework or plugin. The same goes for Backbone.Marionette: great library, but you really need to have something to apply it to before using it.
Starting out, I would suggest having just a single file for all your backbone code.
One of the things that really helped me out was playing around with and extending various jsfiddle demos people had created using backbone. A simple google search will turn up quite a few. I found it a great way to learn as I was able to manipulate working code and get immediate feedback on what worked and what was allowed.
And although backbone is a client-side library, it's often simpler and faster just to ignore html and write stuff out to the console.
Finally, if you're willing to pay for it, I highly recommend Liam McLennan's set of backbone.js training videos on pluralsight.
