I need to do Tree view in React-native. I checked with react-native-final-tree-view. But here we can't have the child click event. Also, I tried with react-native-drillable-object-view, but I need exact behaviour of like this https://reactjsexample.com/a-simple-react-tree-menu-component.
Under this library, they used Typescript to react. Is it possible to do the same behaviour in react-native without using typescript?
If any once know please let me know. I am new in react-native and react.

I am trying to build a web app with Astro + Reactjs, but I got an issue on calling useEffect. Basically useEffect is not calling, I don't get any logs in the terminal or any warnings/errors in the terminal or in the browser.
I am exporting the function as: export default function SecondSection(){}, I changed the file extension from .jsx to .tsx, still no result. I followed all instructions from astro docs to integrate react.
I am trying to use react hooks, like useEffect/useState, but for some reasons it's not working any of that.
What can cause that issue? Thank you for your time.
The first thing to check would be to make sure you are hydrating your React component where you’re using it. In Astro, components ship zero JS by default, just plain HTML. Components will only be interactive in the browser if you add a client:* directive. This is part of Astro’s “Islands Architecture”.
To include a component’s JS you need a client directive saying when to load it. In this example the component will load its JS when the page loads:
---
// src/pages/index.astro
import SecondSection from '../components/SecondSection.jsx';
---
<SecondSection client:load />
There are different directives like client:idle or client:visible that you can use to control exactly when a user needs the interactivity. There’s more about the client directives in Astro’s docs.
How do you extract a specific React component from a library?
I'm trying to get the source code for just this component: https://rsuitejs.com/components/tree/ so that I can modify it for my specific use case.
My plan is to clone the entire library in a new React App, and then just start deleting files that I don't need. Not sure if this is the right way or if there is a more efficient way to to go about this. Any insight would be greatly appreciated!
I have an existing application build with .Net Core Framework. I would like to integrate React components for re-usability purposes which at this point will only be app specific. I have gone through numerous "Hello World!!" tutorials but that doesn't satisfy my need. I have also looked at reactjs.net but that also is not going to help me as the components gets rendered on the View
Scenario
Application has lots of Modals with a form which gets rendered on numerous pages. Currently it is being handled with JavaScript. The JavaScript code gets duplicated a lot to achieve it.
Goal
Would like to have a react component to replace above mentioned functionality to reduce code getting duplicated.
The problem I am facing is I am not sure how will I be able to interact with the component from a jQuery/JavaScript point of view.
Example
I have a DataTable and one of the actions is to click on a certain button to display the Modal. The code is in a separate .js file so it is separate from the View. So in this case if I click on a button I would like to render the react component. I would need to pass props through to the components and that is where I am uncertain how would I handle it :-(
Any suggestion or guidance would be appreciated.
Thanks in advance
Using react in Asp.Net Core application is easy. At first you need to know your back-end will be API based to communicate with react. So if you have not set up your Core application to an API based, it won't work. Also make sure you have installed nodeJs and other dependencies.
To get started with react, create a new folder in your Asp.Net project solution.
Open the folder in your Command line and execute:
npx create-react-app [your--folder--name]
To view your created app, run
npm start
To get started with asp.net, you need to add spa dependencies in your project.
Then you have to set up your ConfigureService method to include:
services.AddSpaStaticFiles(configuration => { configuration.RootPath = "[your--folder--name]/build"; });
Finally set up your Configure method to include:
app.UseSpaStaticFiles();
app.UseRouting();
app.UseEndpoints( ... );
app.UseSpa(spa => {
spa.Options.SourcePath = "[your--folder--name]";
if (env.IsDevelopment()) {
spa.UseReactDevelopmentServer(npmScript: "start");
}
});
I want to create an in-repo addon to make certain modifications (styles, templates, etc.) to an existing ember app in an encapsulated way, but I'm having troubles overriding the templates.
Right now, I'm trying to override an existing component template with the template from a component with the same name in the in-repo addon. My code looks something like this:
// my-app/app/templates/components/foo.hbs
<h1>Some headline<h1>
// my-app/app/lib/my-addon/app/templates/components/foo.hbs
<h1>A different headline<h1> // -> this never shows up
I've tried a lot of switching around the template structure (like putting it in /addons or /app and linking to the template in different ways, but without success. My problem is that ember never uses the template from the addon.
If the component within the addon has a different name, like foobar.hbs, I can call it without a problem.
I'm currently looking through the source code and docs, trying to make sense of this. Is this even accomplishable the way I imagine it?
Thanks a lot!
You'd have to create the component in your ember app which, initially, will mean the component renders as nothing as it's a brand new, empty component. Then you'd dig into your node_modules, find the component file and template and copy over what you'd need to work with.
Here's an example. While working with ember-cli-jsonapi-pagination, I need to customize the paginate-collection component:
I created the component in my application.
I looked at the source: https://github.com/BookingSync/ember-cli-jsonapi-pagination/tree/master/app
In components/paginate-collection/component.js I copied over the component code, but you should be able to import it as well.
In components/paginate-collection/template.hbs I modified the template as needed.
I'm tryng to compare some differents frameworks (angularjs, flux+reactjs and emberjs) doing a minimal todo list application.
You can find my code here:
https://github.com/jurgob/todo_test
(in the flux directory you can find the implementation)
I would like to programmatically fill and send the form to add an item to my todo list.
this code works for angular and emberjs:
$('.addItemText').val('test'); $('.addItemText').change();
$('.addItemBtn').click();
but not for reactjs.
I've also tried with sendkeys jquery plugin (https://github.com/dwachss/bililiteRange/blob/master/jquery.sendkeys.js) without any success.
here is my flux implementation:
https://github.com/jurgob/todo_test/blob/master/flux/main.js
as additional note: I've build a casperjs script to performe them from an headlerss browser, and using casper.sendKeys function it works for all the framework (you can find the code here https://github.com/jurgob/todo_test/blob/master/tests/maintest.js )
That code should work for react, however you can ditch jQuery in this example and use refs. More information about refs can be found here: https://facebook.github.io/react/docs/more-about-refs.html
In reality though you shouldn't be setting properties and triggering events on your own, use state to set properties, and you can submit a form request via XHR rather than filling out a form and simulating a click.
I also had a brief look at your code and noticed you were manipulating props directly, this is an anti-pattern, if you need to keep data in sync between different components consider either passing the components back upstream, creating a global eventemitter, or using a pattern like flux: https://facebook.github.io/react/blog/2014/05/06/flux.html
