MyLibrary | library management system based on ssm has functions | Object-Relational Mapping library

I'm trying to build a project in which when the user clicks a remove button, a specific item gets deleted. But whenever the user clicks the remove button, the particular array does get deleted in the localStorage, but not in the rendered part, I need to refresh the website so that the changes are applied.

But I want the item to get deleted in real time. Is there anything I'm not doing right in the code?

In the removeBooks() function is the one used to delete items. The logic I follow is getting the books localStorage and then looping through all of the items, deleting the one that it is selected. THis is performed correctly, but it doesn't get deleted in real time. I need to refresh the page. I think the last line of this function localStorage.setItem('books', JSON.stringify(myLibrary)) did this correctly but it seems that it doesn't set the data in real time. Is that right?

I'm trying to render localStorage items of the form (fields variable) to the localstorage and then getting them to render them on the loop. But the items are not getting rendered and only a comma is rendered. I can't seem to get around this error...

How to define Matrix with typedef?

We usually put the defined type in a header file, but it needs mpreal::set_default_prec(256); and that's the problem.

I am quite new to MPFR, so my apology if it seems easy. So what is your idea?

I created a React Native library that is a wrapper for using the native iOS framework in the React Native Projects. Earlier I was using .framework & it was working fine. Now I am facing an issue in using this library with .xcframework instead of .framework.

I added this library as a dependency to the project & then on running pod install getting the below error:

[!] [Xcodeproj] Generated duplicate UUIDs:

When I opened the project & try to build it, it builds successfully for the device but fails on the simulator.

Below is the Podspec file that I am using in the library project:

I have a series of class libraries that are used in asp.net-core middleware, and in an IHostedService.

To fetch the user context, I can inject IHttpContextAccessor to grab the HttpContext user:

I followed this tutorial to create my react native library with Native Module. I need to use a mobile SDK developed from BROTHER to use their printers in one of my REACT-NATIVE app.

The library that I wrote works great, and I'm able also to test in the example app that the automatic tool creates.

Now I want to use this library in my REACT-NATIVE app, and I followed these steps:

1. in the path of my react native app i wrote npm install ;
2. in my app I call my library with import MyLibrary from '...name of my library...' without using it inside my component, just import only to try if there is some error;

The result is that my app start and is blocked with white screen and in the log of XCode I receive the following errors that are in loop:

I tried to delete metro cache, remove node_modules, reinstall pods...nothing helped me. If I remove the line import MyLibrary from '...name of my library...' my app works. There is some problem in the way I have to link my local library to my react-native app.

I started my react-native app with EXPO and after I ejected it.

I am building a library app that stores user books. It should take user input, store it into an array and then display it on the page. If I manually enter a few object instances in the array, the displayed values are as they should be (eg.title: harry potter, author: JK Rowling, etc), but my object instances created from user input are displayed like so:

Is a bundler such as rollup needed when creating a react component library? I.e. if all I have is a simple project with Buttons/Checkboxes etc. as typescript files which are then published on npm, doesn’t running tsc with a proper config turn all of it into a dist bundle?

What is the advantage of rollup then? I read that tree shaking might be it, but if the js files live in their own directories, doesn’t the below import a single component, too?

I 'd like to set a data attribute to divs created by looping though an array.
