Integrating new information into an existing JSON file using React Native

Currently, I am attempting to input new data into an existing JSON file using text input. In my project using React Native, I have a JSON file named PartyInfo.json where certain data is stored. The goal is to have this data passed from a form and saved in PartyInfo.json.

const PartyInfo = require('../PartyInfo.json');

let party = {
        name: this.state.name,
        info: this.state.info,
        date: this.state.date,
        price: this.state.price,
    };
    let data = JSON.stringify(party);
    PartyInfo.writeFile('PartyInfo.json', data);

Despite attempting various solutions found in similar questions, none have been successful. Any help would be greatly appreciated.

To incorporate react-native-fs into your project, simply run the command npm i react-native-fs, and then implement the following code to update your file:

 const RNFS = require('react-native-fs');

    const filePath = RNFS.DocumentDirectoryPath + '/YOUR_FILE_NAME';

    RNFS.writeFile(filePath, YOUR_TEXT, 'utf8')
      .then((success) => {
        console.log('File successfully updated');
      })
      .catch((err) => {
        console.log(err.message);
      });
