Creat Register Form React Native to Google Spreadsheet

Create a React Native registration form that sends data to a Google Sheet by creating a Google Form, connecting it to a spreadsheet, generating a POST API URL via Apps Script, and using fetch to submit input data. This approach avoids needing a custom backend server. 

Here's how to create a React Native registration form that sends data to a spreadsheet:

Set Up Google Sheet & API 

1. Create a Sheet: Create a new Google Sheet. Add headers, such as Name, Email, and Password.
2. Create Script: Open Extensions > Apps Script.
3. Add Code: Use the following code to handle POST requests and add rows:
   javascript

   function doPost(e) {
     const sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
     const data = JSON.parse(e.postData.contents);
     sheet.appendRow([data.name, data.email, data.password, new Date()]);
     return ContentService.createTextOutput(JSON.stringify({ 'result': 'success' })).setMimeType(ContentService.MimeType.JSON);
   }
   

4. Deploy: Click Deploy > New deployment, select Web app, set execute as Me, and Who has access to Anyone. Copy the Web app URL.
