We are going to add a settings page to our app. This is going to allow users to pay for our service. The flow will look something like this:

  1. Users put in their credit card info and the number of notes they want to store.
  2. We call Stripe on the frontend to generate a token for the credit card.
  3. We then call our billing API with the token and the number of notes.
  4. Our billing API calculates the amount and bills the card!

To get started let’s add our settings page.

Create a new file in src/containers/Settings.js and add the following.

import React, { useState, useEffect } from "react";
import { API } from "aws-amplify";
import { useHistory } from "react-router-dom";
import { onError } from "../libs/errorLib";
import config from "../config";

export default function Settings() {
  const history = useHistory();
  const [isLoading, setIsLoading] = useState(false);

  function billUser(details) {
    return API.post("notes", "/billing", {
      body: details

  return (
    <div className="Settings">

Next import this component in the header of src/Routes.js.

import Settings from "./containers/Settings";

Add the following below the /signup route in our <Switch> block in src/Routes.js.

<Route exact path="/settings">
  <Settings />

Next add a link to our settings page in the navbar by replacing the return statement in src/App.js with this.

return (
  !isAuthenticating && (
    <div className="App container py-3">
      <Navbar collapseOnSelect bg="light" expand="md" className="mb-3">
        <LinkContainer to="/">
          <Navbar.Brand className="font-weight-bold text-muted">
        <Navbar.Toggle />
        <Navbar.Collapse className="justify-content-end">
          <Nav activeKey={window.location.pathname}>
            {isAuthenticated ? (
                <LinkContainer to="/settings">
                <Nav.Link onClick={handleLogout}>Logout</Nav.Link>
            ) : (
                <LinkContainer to="/signup">
                <LinkContainer to="/login">
      <AppContext.Provider value={{ isAuthenticated, userHasAuthenticated }}>
        <Routes />

You’ll notice that we added another link in the navbar that only displays when a user is logged in.

<LinkContainer to="/settings">

Now if you head over to your app, you’ll see a new Settings link at the top. Of course, the page is pretty empty right now.

Next, we’ll add our Stripe SDK keys to our config.
