in this case, it's okay since the element is relatively simple. The main changes Ive made include: Converting function declarations to. duplicate some code and define the element in both branches of the conditional render. This is a fork of Facebooks original ReactJS Sublime Package.However, anytime the parent of this component re-renders, this component re-renders, and when react sees in the tree, it's going to render a new element too, and thus, the existing one will lose focus. The render() function is similar in both. Exports the component as a module using the export default. It might seem like a simple optimization at first to reuse your input element across both branches of your conditional render. Defines component state using this.state in the constructor(). If you happen to be developing atomic components for your app's design system, you may run into this issue.Ĭonsider the following Input component: export const Input = forwardRef(function Input( Main Page Component import React, = props Submitting the form itself works as does the actual input field when it is located either in the render's return or while being imported as a separate component but not in how I have it coded below. It is highly used together with React and is widely supported in modern browsers. I get no errors from either eslint nor Chrome Inspector. The ES6 syntax gives you more flexibility and productive ways of writing code. While using Chrome's Inspector, it looks like the whole form is being re-rendered instead of just the value attribute of the input field when typing. In my component below, the input field loses focus after typing a character.
