今回はチャットのやり取りを表示する部分を実装していきます。

今回もコーディングとスタイリングが中心になりますので、
時間がない方は下記コードをコピペしてしまっても大丈夫です。

pages/index.tsx

import { ChangeEvent, SyntheticEvent, useState } from 'react'

interface Log {
  prompt: string
  role: string
  content: string
}

export default function Home() {
  const [prompt, setPropmt] = useState('')
  const [isLoading, setIsLoading] = useState(false)
  const [logs, setLogs] = useState<Log[]>([])

  const handleChange = (e: ChangeEvent<HTMLTextAreaElement>) => {
    setPropmt(e.target.value)
  }

  const handleSubmit = async (e: SyntheticEvent) => {
    e.preventDefault()
    setIsLoading(true)

    const res = await fetch('/api/chat', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ prompt: prompt }),
    })
    const data = await res.json()
    if (res.status === 200) {
      console.log(data)
      const logData = {
        prompt: prompt,
        ...data.message,
      }
      setLogs([...logs, logData])
      setPropmt('')
      setIsLoading(false)
    } else {
      console.log(data)
      setIsLoading(false)
    }
  }
