[React]~Ambassador画面4:ヘッダーコンポーネントの実装~

こんにちは、KOUKIです。

今回は、ヘッダーコンポーネントの実装をします。

尚、「React, NextJS and Golang: A Rapid Guide – Advanced」コースを参考にしています。解釈は私が勝手に付けているので、本物をみたい場合は受講をお勧めします!

ヘッダーコンポーネントの変更

まずは、以前作成したHeader.tsxに実装しているヘッダーコンポーネントのコンテンツを変えてみましょう。

// components/Header.tsx
import { useState } from 'react'
import { Link } from 'react-router-dom'

const Header = () => {
  const [title, setTitle] = useState('Welcome')
  const [description, setDescription] = useState('Share links to earn money')

	return (
		<section className="py-5 text-center container">
          <div className="row py-lg-5">
            <div className="col-lg-6 col-md-8 mx-auto">
              <h1 className="fw-light">{title}</h1>
              <p className="lead text-muted">{description}</p>
              <p>
                <Link to={'/login'} className="btn btn-primary my-2">Login</Link>
                <Link to={'/register'} className="btn btn-secondary my-2">Register</Link>
              </p>
            </div>
          </div>
        </section>
	)
}

export default Header

// components/Header.tsx

import { useState } from 'react'

import { Link } from 'react-router-dom'

const Header = () => {

const [title, setTitle] = useState('Welcome')

const [description, setDescription] = useState('Share links to earn money')

return (

<h1 className="fw-light">{title}</h1>

<p className="lead text-muted">{description}</p>

<p>

<Link to={'/login'} className="btn btn-primary my-2">Login</Link>

<Link to={'/register'} className="btn btn-secondary my-2">Register</Link>

</p>

</div>

</section>

)

}

export default Header

Redux Storeへ接続

ヘッダーコンポーネントもRedux Storeへ接続し、Stateの値を取得できるようにしましょう。

// components/Header.tsx
...
import { User } from '../models/user'
import { connect } from 'react-redux'

// propsを渡せるようにする
const Header = (props: {user: User}) => {
 ...
}

// Redux Storeへ接続
export default connect(
	(state: {user: User}) => ({
		user: state.user
	})
)(Header)

// components/Header.tsx

...

import { User } from '../models/user'

import { connect } from 'react-redux'

// propsを渡せるようにする

const Header = (props: {user: User}) => {

...

}

// Redux Storeへ接続

export default connect(

(state: {user: User}) => ({

user: state.user

})

)(Header)

表示の切り替え

ナビゲーションの時と同様に、ログイン済みの場合は、ユーザー情報を表示するようにします。

// components/Header.tsx
import { useEffect, useState } from 'react'
...

const Header = (props: {user: User}) => {
  const [title, setTitle] = useState('Welcome')
  const [description, setDescription] = useState('Share links to earn money')

  useEffect(() => {
    if (props.user?.id) {
      setTitle(`$${props.user.revenue}`)
      setDescription('You have earned this far')
    } else {
      setTitle('Welcome')
      setDescription('Share links to earn money')
    }
  }, [props.user])

  let buttons;
  if (!props.user?.id) {
    buttons = (
      <p>
        <Link to={'/login'} className="btn btn-primary my-2">Login</Link>
        <Link to={'/register'} className="btn btn-secondary my-2">Register</Link>
      </p>
    )
  }

	return (
		<section className="py-5 text-center container">
          <div className="row py-lg-5">
            <div className="col-lg-6 col-md-8 mx-auto">
              <h1 className="fw-light">{title}</h1>
              <p className="lead text-muted">{description}</p>
              {buttons}
            </div>
          </div>
        </section>
	)
}
...

// components/Header.tsx

import { useEffect, useState } from 'react'

...

const Header = (props: {user: User}) => {

const [title, setTitle] = useState('Welcome')

const [description, setDescription] = useState('Share links to earn money')

useEffect(() => {

if (props.user?.id) {

setTitle(`$${props.user.revenue}`)

setDescription('You have earned this far')

} else {

setTitle('Welcome')

setDescription('Share links to earn money')

}

}, [props.user])

let buttons;

if (!props.user?.id) {

buttons = (

<p>

<Link to={'/login'} className="btn btn-primary my-2">Login</Link>

<Link to={'/register'} className="btn btn-secondary my-2">Register</Link>

</p>

)

}

return (

<h1 className="fw-light">{title}</h1>

<p className="lead text-muted">{description}</p>

{buttons}

</div>

</section>

)

}

...

Userモデルに、revenueを追加します。

// models/user.ts

export class User {
...
	revenue?: number // 追加
}

// models/user.ts

export class User {

...

revenue?: number // 追加

}

また、現状ログアウトするとログインページに遷移してしまうので、前回作成したナビゲーションからリダイレクト処理を削除し、ユーザー情報を設定する処理を追加します。

// components/Nav.tsx
import { Dispatch } from 'react'
import { connect } from 'react-redux'
import { User } from '../models/user'
import { Link } from 'react-router-dom'
import axios from 'axios'
import { setUserAction } from '../redux/actions/setUserAction'

// propsをanyへ変更
const Nav = (props: any) => {
	// const [redirect, setRedirect] = useState(false)

	const logout = async () => {
		await axios.post('logout')
		// setRedirect(true)
		props.setUser(null) // ユーザをセット
	}

	// if (redirect) {
	// 	return <Redirect to={'/login'} />
	// }

	let menu

	if (props.user?.id) {
...
		)
	} else {
...
	}


	return (
	...
	)
}

export default connect(
	(state: {user: User}) => ({
		user: state.user
	}),
// dispatchを追加
  (dispatch: Dispatch<any>) => ({
    setUser: (user: User) => dispatch(setUserAction(user))
  })
)(Nav)

// components/Nav.tsx

import { Dispatch } from 'react'

import { connect } from 'react-redux'

import { User } from '../models/user'

import { Link } from 'react-router-dom'

import axios from 'axios'

import { setUserAction } from '../redux/actions/setUserAction'

// propsをanyへ変更

const Nav = (props: any) => {

// const [redirect, setRedirect] = useState(false)

const logout = async () => {

await axios.post('logout')

// setRedirect(true)

props.setUser(null) // ユーザをセット

}

// if (redirect) {

// return <Redirect to={'/login'} />

// }

let menu

if (props.user?.id) {

...

)

} else {

...

}

return (

...

)

}

export default connect(

(state: {user: User}) => ({

user: state.user

}),

// dispatchを追加

(dispatch: Dispatch<any>) => ({

setUser: (user: User) => dispatch(setUserAction(user))

})

)(Nav)

プロファイルページの作成

プロファイルページを作成していなかったので、この機会に作成しましょう。

// pages/Profile.tsx
import { Dispatch, SyntheticEvent, useEffect, useState } from 'react'
import { connect } from 'react-redux'
import { User } from '../models/user'
import { setUserAction } from '../redux/actions/setUserAction'
import Layout from '../components/Layout'
import axios from 'axios'

// Props追加
const Profile = (props: any) => {
	const [first_name, setFirstName] = useState("")
	const [last_name, setLastName] = useState("")
	const [email, setEmail] = useState("")
	const [password, setPassword] = useState("")
	const [password_confirm, setPasswordConfirm] = useState("")

	const userInfo = 'users/info'
	const userPassword = 'users/password'

	// propsからデータを設定するのでAPIからデータを取得する必要はなくなる
	useEffect(() => {
		console.log(props.user)
		setFirstName(props.user.first_name)
		setLastName(props.user.last_name)
		setEmail(props.user.email)
	}, [props.user]) // propsを渡す

	const infoSubmit = async(e: SyntheticEvent) => {
		e.preventDefault()

		const { data } = await axios.put(userInfo, {
			first_name,
			last_name,
			email
		})

		// dispatchを実行
		props.setUser(data)
	}

	const passwordSubmit = async(e: SyntheticEvent) => {
		e.preventDefault()

		await axios.put(userPassword, {
			password,
			password_confirm
		})
	}

	return (
		<Layout>
			<h3>Account Information</h3>
			<form onSubmit={infoSubmit}>
				<div className="mb-3">
					<label>First Name</label>
					<input
						className="form-control"
						defaultValue={first_name}

					/>
				</div>
				<div className="mb-3">

					/>
				</div>
				<button
					className="btn btn-outline-secondary"
					type="submit">

				</button>
			</form>

			<form onSubmit={passwordSubmit}>

				<div className="mb-3">

					/>
				</div>
				<button
					className="btn btn-outline-secondary"
					type="submit">
						Submit
				</button>
			</form>
		</Layout>
	)
}

export default connect( (state: {user: User}) => ({
		user: state.user
	}),
	// dispatchを追加
	(dispatch: Dispatch<any>) => ({
		setUser: (user: User) => dispatch(setUserAction(user))
	})
)(Profile)

user: state.user

}),

// dispatchを追加

(dispatch: Dispatch<any>) => ({

setUser: (user: User) => dispatch(setUserAction(user))

})

)(Profile)

内容は、Admin画面で実装した時のものとほぼ一緒です。

このページへのルートを設定します。

// App.tsx
...
import Profile from './pages/Profile'

function App() {
  return (
    <BrowserRouter>
...
      <Route path={'/profile'} component={Profile} />
    </BrowserRouter>
  );
}

export default App;

// App.tsx

...

import Profile from './pages/Profile'

function App() {

return (

...

</BrowserRouter>

);

}

export default App;

バグの修正

ページを更新後、「$undefined」になりました。これの修正を行いましょう。

Layout.tsxを修正します。

// components/Layout.tsx
...
import { useLocation } from 'react-router'
...
const Layout = (props: any) => {
...
	const location = useLocation()

	useEffect(() => {
...
	}, [])

  // Header表示/非表示の判定
	let header
	if (location.pathname === '/' || location.pathname === '/backend') {
		header = <Header />
	}

	return (
		<div>
			<Nav />
			<main>
				{header} // 追加
...
	)
}

....

// components/Layout.tsx

...

import { useLocation } from 'react-router'

...

const Layout = (props: any) => {

...

const location = useLocation()

useEffect(() => {

...

}, [])

// Header表示/非表示の判定

let header

if (location.pathname === '/' || location.pathname === '/backend') {

header = <Header />

}

return (

<div>

<Nav />

<main>

{header} // 追加

...

)

}

....

URLがルートかbackend以外の場合は、Headerコンポーネントを非表示にしました。
