How we are using Sentry for mobile apps

Sentry redux middleware

const sentryMiddleware: Middleware<State, Action> = ({ getState }) => next => action => {
const { type, } = action;
message: `Action: ${type}`,
category: 'action',
data: rest,

const { fcmToken } = getState().notifications;
fcmToken && Sentry.setTag('fcm_token', fcmToken);

return next(action);
