Selected element within list in React

I want to apply different style for selected element from a long list. I’m passing to React component element as props: currentId and selectedId. Inside render function, I compare both ids and apply proper styles. When clicking any element from the list, I fire an action with the new selected Id and all elements in the list will re-render(because selectedId prop does change). If the list has 1000 element and I click one of them, It would be nice to only update 2 elements (new selected and deselected ones) not all of them. Is these a better way to handle this scenario in React? Selected element within list in React Selected element within list in React test {$excerpt:n}

how to add Firebase to a Vuex todo list app?

I am building a simple Vue.js todo list app using Vue.js, Vuex, and Firebase. The Vuex store dispatches, commits, and returns the inputted data just as it should, but I want to be able to connect the app to a Firestore database. So far, I have managed to set up the app so that data is pushed into the collection, but I also want the database to return a snapshot of the firestore data to the DOM, as well as to enable deleting of data from database. I have experience with these Firestore methods in simple non Vuex-projects, but am not sure how to synthesize Firestore methods with a Vuex store. How can I do this? Here is what I have so far. Thanks so much! <!--GetTodo.vue--> <template> <div id="get-todo" class="container"> <input class="form-control" :value="newTodo" @chan...

Error in sending and receiving the packets

I am writing an application to inject packets to the adapter using the winpcap API “pcap_sendpacket” and I am also running a separate thread to get all the packets received by the adapter from the network which forwards the packets to my application for processing when it receives any packet from the network. Problem is, I am seeing the injected packets in the “pcap_loop” callback which I am sending using the “pcap_sendpacket”. This is causing an issue of sending the injected packets again back to the application. What I should do, If I don’t want to receive the injected packets? How to differentiate between the injected packets and the packets received by the network adapter from the network? Error in sending and receiving the packets ...
