Steps

  1. Choose a stable directory path for the profile: const profileDir = path.join(os.homedir(), '.pw-profile', 'myapp')
  2. Launch the context: const context = await chromium.launchPersistentContext(profileDir, { headless: false, args: ['--no-sandbox'] })
  3. The returned context is the only context; get a page with const page = await context.newPage()
  4. Perform login or setup actions — cookies, local storage, and IndexedDB are automatically written to profileDir on close
  5. On subsequent runs, pass the same profileDir; Playwright restores the saved session data
  6. Call await context.close() to flush all state to disk before the process exits
