I’m adding Google Calendar features to my React app and need an experienced developer to wire everything up smoothly. Scope • Implement Google OAuth in the frontend so a user can grant calendar access with the familiar Google consent screen. • Once authenticated, expose clean helper methods in React (e.g., useCalendar hooks or simple service functions) that let the rest of the UI talk to the Google Calendar API. • Keep tokens secure and refresh them transparently. • Provide concise setup notes so I can reproduce the flow locally and on staging. Tech Context The UI is built with React (hooks + functional components). A lightweight Node/Express backend is already in place, but for now the calendar calls will originate from the frontend, exactly as selected. Feel free to suggest small backend tweaks if they simplify security or token storage. Deliverables - Working React code that completes the OAuth flow and confirms API access in a demo page. - Clear instructions (env variables, Google Cloud console steps, npm packages). - Brief hand-off session or screencast to walk me through the integration. This is a focused, medium-sized task. If everything goes well, I may extend the work to cover additional calendar operations and deeper Node integration.
