为什么我的反应组件不断重新渲染？

Question

I'm trying to embed a tockify calender into a component, within a react project I'm building. I should note that I'm using a library called react-script-tag that allows me to use <script/> tags within my component. Anyway, the calender is rendering - but then keeps on re-rendering as if it's stuck in some sort of loop. I have a feeling I need to implement some sort of lifecycle method. Any suggestions? Code as follows:

import React from 'react'
import Nav from './Nav'
import ScriptTag from 'react-script-tag'

class Events extends React.Component {

    render() {
    return (
        <div>
            <Nav/>
             <div data-tockify-component="calendar" data-tockify-calendar="hzevents2"></div>
            <ScriptTag isHydrating={false} data-cfasync="false" data-tockify-script="embed" src="https://public.tockify.com/browser/embed.js"></ScriptTag> 
        </div>
    )
    }
}

export default Events

Answer 1

The documentation of 'react-script-tag' says

It is recommended that the Script tag is placed in a component that only renders once in the entire life of your app. Otherwise, a new

tag will be appended each time the component mounts again. There are plans down the road to prevent this.

You may want to use a pure component to prevent rerendering.

Edit: Regardless of my answer you should show the rest of your code to be able to detect the problem.

Use React.PureComponent instead of React.Component because of React.PureComponent will prevent to re-rendering if there is no need or update.
