View
The View
component is a part of a React application that handles the user interface for a chat feature. It uses various contexts to manage state and behavior, such as view mode, sound, audio, and language settings. The component also controls a microphone feature and speech recognition. In layman's terms, this component is like the control center for a chat room where users can interact with each other, and it manages how the chat room looks, sounds, and behaves.
import React, { useContext } from "react"
import styles from "./View.module.css"
import { ViewMode, ViewContext } from "../context/ViewContext"
import Chat from "../components/Chat"
import CustomButton from "../components/custom-button"
import { LanguageContext } from "../context/LanguageContext"
import { SoundContext } from "../context/SoundContext"
import { AudioContext } from "../context/AudioContext"
The component imports necessary modules, styles, and contexts. useContext
is a React hook that allows the component to access the state and functions provided by the imported contexts.
function View({templateInfo}) {
...
}
The View
component receives templateInfo
as a prop.
const { setViewMode } = React.useContext(ViewContext)
const [micEnabled, setMicEnabled] = React.useState(false)
const [speechRecognition, setSpeechRecognition] = React.useState(false)
const { playSound } = React.useContext(SoundContext)
const { isMute } = React.useContext(AudioContext)
const { t } = useContext(LanguageContext);
The component uses several pieces of state and context:
-
setViewMode
: A function fromViewContext
to change the view mode. -
micEnabled
andsetMicEnabled
: State variables to manage the microphone status. -
speechRecognition
andsetSpeechRecognition
: State variables to manage the speech recognition status. -
playSound
: A function fromSoundContext
to play a sound. -
isMute
: A state variable fromAudioContext
to check if the audio is muted. -
t
: A function fromLanguageContext
to translate text.
const back = () => {
setViewMode(ViewMode.SAVE)
!isMute && playSound('backNextButton');
if (speechRecognition)
speechRecognition.stop()
setMicEnabled(false)
}
The back
function changes the view mode to SAVE
, plays a sound if audio is not muted, stops speech recognition if it's active, and disables the microphone.
return (
...
)
The component renders a chat interface with a title, a Chat
component, and a CustomButton
component. The Chat
component receives several props related to the microphone and speech recognition. The CustomButton
component is configured to act as a back button.
export default View
The View
component is exported for use in other parts of the application.
