Cookies and Storage

Reading cookies

// All cookies for a URL
const cookies = webview.getCookies('https://example.com');

// Every cookie the webview has
const all = webview.getCookies();

for (const c of cookies) {
  console.log(c.name, '=', c.value, '  domain:', c.domain);
}

WebviewCookie fields:

Field Type Description
name string Cookie name
value string Cookie value
domain string? Owning domain
path string? URL path scope
httpOnly boolean? Not accessible from JS
secure boolean? HTTPS-only
sameSite 'strict' \| 'lax' \| 'none'? Cross-site policy 
webview.setCookie({
  name: 'session',
  value: 'abc123',
  domain: 'example.com',
  path: '/',
  httpOnly: true,
  secure: true,
  sameSite: 'strict',
});

// Specific domain + path
webview.deleteCookie('session', 'example.com', '/');

// Name only (removes across all domains/paths)
webview.deleteCookie('session');

Clearing all browsing data

Wipes cookies, cache, local storage, IndexedDB, and session data:

webview.clearAllBrowsingData();

Incognito mode

Pass incognito: true when creating the webview to start a session with no persistent storage at all — cookies, cache, and local storage are discarded on exit:

const webview = win.createWebview({
  url: 'https://example.com',
  incognito: true,
});
