    <ApolloProvider client={client}>
      <Router>
        <div>
          <StoreProvider>
            <Nav />
            <Switch>
              <Route exact path="/" component={Home} />
              <Route exact path="/login" component={Login} />
              <Route exact path="/signup" component={Signup} />
              <Route component={NoMatch} />
            </Switch>
          </StoreProvider>
        </div>
      </Router>
    </ApolloProvider>
