I have just begun to work with Apache-Camel. I am looking for a component to cause the route, execute only once. Right now I use 'File' component for running the route. I think it might not be the proper way since the route does not need any files. Any advice would be appreciated.
Welcome to Camel! Have you considered using a Timer, with 'repeatCount' specified?

I found different ways of navigation in React Js.
For example
Using Link, NavLink, Redirect Component, history.push and history.replace.
I am a bit confused, which method is perfect or recommended. Thanks.
I'm new to React as well and I think using any sort of Link/Navlink along with the Switch Route is a good way. It helps me sort of modularize the routing, no matter where the path changes from.
As a new learner, you only need to know <Route>, <Switch>, and <Link>. And also <Link> and <a> difference. The rest you mentioned comes with intermediate level React. So, I kindly advise you to take it bit by bit and also try to make your questions more to the point as editor noted in comment.
I am using React 16 & Hydrate. My server.js uses StaticRouter and my client uses BrowserRouter. I am using Material-UI.
I constantly get class mismatch warning.
Why is this warning?
What is the significance of this warning?
Is it a security risk or just best practice?
How do I stop getting this warning?
I know, we should have only one specific question to be asked, but if some could guide me to some really good documentation page, which will answer all these questions.
please help....
Material UI generates a different class for each component after rendering. It is literally not possible to predict what the end class name will be. While you're on localhost the class could be .newLoanStepper-root-247 but once you build the app the class name would change to something like .jss01026
You will need to follow the MUI guide for server rendering if you want to use the library https://material-ui.com/guides/server-rendering/
I've just implemented React Router 4 in my React/Redux app which was using multiple entry points up to this point.
I changed my code to have a single entry point and set up a catch-all route on the server side so that react router would handle requests on the client side.
Initially, everything seems to work OK but it takes a long long time before the right component is displayed. As soon as I click the link, I see the URL in the browser address bar change immediately but I have to wait sometimes more than 10-15 seconds before the right component is loaded.
I've also noticed that after a click or two, it stops working all together.
I don't get any errors and I put a break point on the server to see if I'm somehow hitting the backend when I click a link but looks like I'm not even going to the backend.
How can I debug/troubleshoot this? React Router is just a bunch of components and there's not much code to speak of that I can debug.
Has anyone experienced this issue? I'd appreciate any ideas you may have. Thanks.
The answer was in this post: React Router v4 not rendering components
Because I'm using Redux, I needed to use withRouter.
I have a React/Redux app in production that talks to an API. In a few situations the app will error as a result of data from the API (that we are unable to entirely control) and when this happens it takes down the entire react-router route.
We are using PropTypes as recommended in the Redux real-world example but these do not help in production. Is there a way to prevent these errors from taking down the entire route, and log the exception?
React will probably get error boundaries soon, as discussed in the issue #2461.
Somebody in that thread built a workaround until the feature is officially supported.
I hope this helps you for your use case.
I'm using server side rendering for my React app but can't wrap my head around the logic for showing error pages when something goes wrong.
For example:
User requests /article/123
Something goes wrong while fetching the article
I would like to show a 500 error page
The server side part was easy. I tell React-Router to serve my error component. So far so good.
But when the page is served, the client-side javascript is executed and it takes over rendering. React-Router see the url /article/123 and loads the component that shows the article (but fails since the data is not present..)
Is there a way to let the client-side know that we want to show the error component instead?
The only think I could think of is the following: Add the error to the global redux state. Before rendering a component, check if the error is present in the global state and show the error component instead.. But the downside of this is that you have to implement that checking logic in all of your components. There should be some kind more elegant way to fix this..
There's a few different ways to implement client-side error handling; I find using Higher Order Components work best. You would create a wrapper component that checks for errors from the server response. If it finds one, serve the appropriate error page. If the HOC doesn't detect an error, serve the component the user originally requested.
Here's a great explanation on how to implement HOC:
