Javascript Why Does React Call My Component More Times Than Needed

React Call Call Your React Components When i click the button for the first time, setcounter(1) is called, which cuases the component to rerender reexecute (as expected) causing the alert to appear for a second time and the ref counter to increase. The fetch is async await, then setstate. the fetch function call is in useeffect. the component renders twice, even in production build. i understand why, because state changes from its initial value of empty array to an array of objects, causing a render. is it supposed to render twice or can should i optimize somehow?.

Javascript Why Does React Call My Component More Times Than Needed It seems like your popup keeps appearing again and again because it's placed inside your datatable, which refreshes every time something changes. to stop the popup from showing up repeatedly, you could either control when it shows up from a broader perspective or use a feature in react called portals to put the popup outside of the main group. In react, the useeffect hook is called multiple times because it is designed to re run whenever certain values (referred to as "dependencies") change. here are a few reasons why an useeffect might be called twice: missing dependencies: if you forget to include all of the values that the effect depends on, it will run twice. Api calls being made twice in react can be a result of several issues, including react strict mode in development, improper use of useeffect with missing dependencies, component re renders, or. Components become more than functions. react can augment them with features like local state through hooks that are tied to the component’s identity in the tree. component types participate in reconciliation. by letting react call your components, you also tell it more about the conceptual structure of your tree.

The reason why all these happen is react.strictmode. let's dive into some real examples in order to replicate this and then investigate why this is happening in the first place. Some of my components are rendered out multiple times, causing my useeffcts to run up to three times. it’s causing double registrations, triggers of tagging events so i want to get rid of this. how can i see why and how my components are getting rendered? what is likely and how do i solve it?. The remedy for both of these things is to read through the official react documentation. if you are working on a function component – read about the useeffect hooks – read both of those sections in detail and make sure you really understand it. for class components, read about componentdidmount. To fix this issue, you can disable the strictmode by removing the < react.strictmode> closing tag from your index.js file. this will prevent react from re rendering components unnecessarily and will stop methods from being called twice.
