reactjs – 如何使React组件看起来更具可读性和清洁性？

我一个月前就开始和React合作了.现在我正在构建一步一步的应用程序.我有我的代码,但我觉得我可以更清洁它.

有人可以检查这段代码..并给我建议,我可以学习和提高我的React技能？

我的代码有效,但想知道这是否更清洁：

import React, { Component } from 'react';

import axios from 'axios';

class App extends Component {

    state = {
        fragrances: []
    }

    componentDidMount() {
    const URI = 'http://localhost:1337/';
    const post_type = 'fragrances';

        axios
        .get(`${URI + post_type}`)

        .then(response => {
            const fragrances = response.data;
            this.setState({ fragrances });
        })

        .catch(error => {
            console.log('An error occurred:', error);
        });
    }

    render() {
    const { fragrances } = this.state;
        return (
        <React.Fragment>
            <div className="row">
            {
                fragrances.map((fragrance, index) => {
                const url = 'http://localhost:1337';
                const image = fragrance.Image;
                const name = fragrance.Name;
                const category = fragrance.Category;
                const desc = fragrance.Description;
                    return (
                        <div key={index} className="col-sm-6 col-xs-12">
                            <div className="fragrance">
                                { image ? <img className="fragrance__image" src={url + image.url} alt={name} /> : <h4>Geen foto beschikbaar.</h4>}
                                { name ? <h2 className="fragrance__title">{name}</h2> : 'Geen titel aanwezig.'}
                                { category ? <span class="fragrance__category">{category}</span> : '    '}
                                { desc ? <p className="fragrance__description">{desc}</p> : 'Geen omschrijving aanwezig.'}
                            </div>
                        </div>
                    )
                })
            }
            </div>
        </React.Fragment>
        )
    }
}
export default App;

提前致谢.

创建< Fragrance />组件会使它更干净,加上使用ES6解构.此外,片段在列表中是不必要的,因为它被包装在单个< div className =“row”>中：

....

render() {
  const { fragrances } = this.state;
  const url = 'http://localhost:1337';

  return (
      <div className="row">
        {fragrances.map((fragrance, index) => {
           const { Image: image, Name: name, Category: category, Description: desc } = fragrance;
            return (
              <Fragrance
                key={index}
                image={image}
                name={name}
                category={category}
                desc={desc}
              />
            )
          })
        }
      </div>
    )
  }

...

Fragrance.js

const Fragance = ({name, category, image, desc }) => (
  <div key={index} className="col-sm-6 col-xs-12">
    <div className="fragrance">
      { image ? <img className="fragrance__image" src={url + image.url} alt={name} /> : <h4>Geen foto beschikbaar.</h4>}
      { name ? <h2 className="fragrance__title">{name}</h2> : 'Geen titel aanwezig.'}
      { category ? <span class="fragrance__category">{category}</span> : '    '}
      { desc ? <p className="fragrance__description">{desc}</p> : 'Geen omschrijving aanwezig.'}
     </div>
   </div>
)

export default Fragrance;
