View

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.

Imports

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.

Component Function

function View({templateInfo}) {
  ...
}

The View component receives templateInfo as a prop.

State and Context

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 from ViewContext to change the view mode.
• micEnabled and setMicEnabled: State variables to manage the microphone status.
• speechRecognition and setSpeechRecognition: State variables to manage the speech recognition status.
• playSound: A function from SoundContext to play a sound.
• isMute: A state variable from AudioContext to check if the audio is muted.
• t: A function from LanguageContext to translate text.

Back Function

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.

Render

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

export default View

The View component is exported for use in other parts of the application.
