Why react doesn't call render when state is changed?

由 北慕城南 提交于 2019-12-24 01:15:00
问题 I have problem with automatically re-rendering view, when state is changed. State has been changed, but render() is not called. But when I call this.forceUpdate() , everything is ok, but I think that's not the best solution. Can someone help me with that ? class TODOItems extends React.Component { constructor() { super(); this.loadItems(); } loadItems() { this.state = { todos: Store.getItems() }; } componentDidMount(){ //this loads new items to this.state.todos, but render() is not called

Chrome is slow to load first AJAX response

由 为君一笑 提交于 2019-12-23 18:58:40
问题 I am building an application using React and Flux. Clicking in a list of items initiates an action which then starts (via an effect) an AJAX request using axios (though I have tried superagent-bluebird-promise with the same results). The issue is that using Google Chrome, when first making this request, there is a delay of approximately two seconds between clicking the item in the list and the AJAX request being initiated. Subsequent clicks instantly start loading the request. Using Firefox,

Flux store emitting changes to specific react components rather than all components.

问题 Struggling to find or come up with an elegant answer to this one: If I have multiple dynamic react components that are listening to one flux store to update their child components is it possible to emit changes to specific components rather than emitting changes to all the components that are registered to listen to changes on that store? E.G: A dynamic component has a button and when clicked its tells the flux store to send some data to API. The dynamic component will it update its child

data flow in react application

问题 I am currently learning react and I have run into the problem of elegently extracting states from my components. basically I have a few components which contains forms and other inputs from which I need the data in my business logic, the data I need is coupled with the state of the component. From what I understand the data should have unidirectional flow but I can't think of how I can make my data flow back towards my business logic. I could just make some interface functions which call the

React Flux - Return value from flux dispatcher / store

由 断了今生、忘了曾经 提交于 2019-12-23 01:55:30
问题 I am using the flux-pattern and the flux dispatcher. I need to return a value from 'TextStore' to an action after creating a new TextItem because I need to reference it in another store. Here is a very simple version of what I want to do: // stores.ts var TextStore = { add(){ // here I want to return a new ID return createRandomID(); } ... } var ModuleStore = { labelTextID; // refers to `id` on Text ... } // moduleactions.ts ... import PageActions from './PageActions'; var ModuleActions = {

Reducing an entire subtree with redux combineReducers

由 橙三吉。 提交于 2019-12-22 06:00:34
问题 I have a reducer tree that looks like this: module.exports = combineReducers({ routing: routeReducer, app: combineReducers({ setup: combineReducers({ sets, boosters }), servers: combineReducers({ servers }) }) }); Now the setup key holds a form that needs to be reset once we've submitted it. However I have no way to access the entire setup tree because using combineReducers means the reducers only manipulate the data at the leaf nodes of the tree ( sets and boosters in this case). My first

Flux with Alt - Simultaneous dispatches means wrong design pattern?

由 一笑奈何 提交于 2019-12-22 00:02:30
问题 I build an app with pure React. Its primary page shows multiple movies (user added). Users can vote and comment on every movie listed. I have a MovieCard component, which is responsible for a single movie. Then in Home I render an array of MovieCard components. Next I decided to implement a call to foreign movie database API, to get relevant movie information. It worked fine. Then I decided to refactor it in Flux pattern, using Alt and following the guidelines of this tutorial. Everything

问题 This is more of an architectural question regarding react than a specific issue, but what is considered best practice for managing state/props with a layout component and a several child components which are rendered based on the url?
