JasterixReact and I haven't been the best of friends recently. Passing data between components and working from component to subcomponents, each with different states isn't hasn't been as intuitive for me.
So today, I decided to make the time to find some helpful patterns for structuring your React files.
Components that will probably hold state
- Forms
- Inputs
- Conditional display
General Form.js
state ={
title: "",
description: ""
}
handleChange = (event) => {
this.setState({title: event.target.value})
}
handleSubmit = (event) => {
this.props.newBook(this.state)
}
...
return (
<form onSubmit={this.handleSubmit}>
<input onChange={this.handleChange} value= {this.state.title}>
General App.js
state = {
books: []
}
ComponentDidMount() {
fetch(url)
.then(res => res.json())
.then(data => {
this.setState({books: data})
}
handleNewBook = (bookData) => {
const newBook = { ...bookData }
this.setState({books:[...this.state.books, newBook]})
}
render() {
return(
<NewBookForm onNewBook = {this.handleNewBook} />
<Container books= {this.state.books} />
General Container.js
render() {
const books = this.props.books.map(bookData => <Book book={bookData} />)
return (
<div>
{ books }
</div>
)
General Book.js
<div>
<h1> {this.props.book.title} </h1>
<p> {this.props.book.content} </p>
</div>

- I also recommend this article, which offers a deep dive into passing props between components (although it does use this.state, which I believe makes React more difficult)
