Verifying username is an import feature of most web apps. It allows the user to check if they entered a valid email, and for the owner of the app to know whether the user is actually a human.
Building user verification feature into an app is easy. To make it easy and secure, we have to store a flag in the user table to save the verification status of the user and a verification token so that only the user can use the verification link to verify their account. We use SendGrid to send email so that we can prevent it from going to the spam folder and send email without much configuration.
In this article, we will make a simple Bitbucket app with authentication. We will let users sign up for an account and set their Bitbucket username and password for their account. Once the user is logged in and set their Bitbucket credentials, they can view their repositories and the commits for each repository. The user will have to verify their user account to get access to the authenticated pages.
Bitbucket is a great repository hosting service that lets you host Git repositories for free. You can upgrade to their paid plans to get more features for a low price. It also has a comprehensive API for automation and getting data.
Developers have made Node.js clients for Bitbucket’s API. We can easily use it to do what we want like manipulating commits, adding, removing, or editing repositories, tracking issues, manipulating build pipelines and a lot more.
The Bitbucket.js package is one of the easiest packages to use for writing Node.js Bitbucket apps. All we have to do is log in with the Bitbucket instance with our Bitbucket username and password and call the built in functions listed at https://bitbucketjs.netlify.com/#api-_ to do almost anything we want with the Bitbucket packages.
Our app will consist of an back end and a front end. The back end handles the user authentication and communicates with Bitbucket via the Bitbucket API. The front end has the sign up form, log in form, a settings form for setting password and Bitbucket username and password.
To start building the app, we create a project folder with the backend folder inside. We then go into the backend folder and run the Express Generator by running npx express-generator . Next we install some packages ourselves. We need Babel to use import , BCrypt for hashing passwords, Bitbucket.js for using the Bitbucket API. Crypto-JS for encrypting and decrypting our Bitbucket password, Dotenv for storing hash and encryption secrets, Sequelize for ORM, JSON Web Token packages for authentication, CORS for cross domain communication and SQLite for database.
Run npm i @babel/cli @babel/core @babel/node @babel/preset-env bcrypt bitbucket cors crypto-js dotenv jsonwebtoken sequelize sqlite3 to install the packages.
In the script section of package.json , put:
"start": "nodemon --exec npm run babel-node -- ./bin/www",
"babel-node": "babel-node"
to start our app with Babel Node instead of the regular Node.js runtime so that we get the latest JavaScript features.
Then we create a file called .babelrc in the backend folder and add:
{
"presets": [
"@babel/preset-env"
]
}
to enable the latest features.
Then we have to add Sequelize code by running npx sequelize-cli init . After that we should get a config.json file in the config folder.
In config.json , we put:
{
"development": {
"dialect": "sqlite",
"storage": "development.db"
},
"test": {
"dialect": "sqlite",
"storage": "test.db"
},
"production": {
"dialect": "sqlite",
"storage": "production.db"
}
}
To use SQLite as our database.
Next we add a middleware for verifying the authentication token, add a middllewares folder in the backend folder, and in there add authCheck.js . In the file, add:
const jwt = require("jsonwebtoken");
const secret = process.env.JWT_SECRET;
export const authCheck = (req, res, next) => {
if (req.headers.authorization) {
const token = req.headers.authorization;
jwt.verify(token, secret, (err, decoded) => {
if (err) {
res.send(401);
} else {
next();
}
});
} else {
res.send(401);
}
};
We return 401 response if the token is invalid.
Next we create some migrations and models. Run:
npx sequelize-cli model:create --name User --attributes username:string,password:string,bitBucketUsername:string,bitBucketPassword:string,verified:boolean,verifyToken:string
to create the model. Note that the attributes option has no spaces.
Then we add unique constraint to the username column of the Users table. To do this, run:
npx sequelize-cli migration:create addUniqueConstraintToUser
Then in newly created migration file, add:
"use strict";
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.addConstraint("Users", ["username"], {
type: "unique",
name: "usernameUnique"
});
},
down: (queryInterface, Sequelize) => {
return queryInterface.removeConstraint("Users", "usernameUnique");
}
};
Run npx sequelize-cli db:migrate to run all the migrations.
Next we create the routes. Create a file called bitbucket.js and add:
var express = require("express");
const models = require("../models");
const CryptoJS = require("crypto-js");
const Bitbucket = require("bitbucket");
const jwt = require("jsonwebtoken");
import { authCheck } from "../middlewares/authCheck";
const bitbucket = new Bitbucket();
var router = express.Router();
router.post("/setBitbucketCredentials", authCheck, async (req, res, next) => {
const { bitBucketUsername, bitBucketPassword } = req.body;
const token = req.headers.authorization;
const decoded = jwt.verify(token, process.env.JWT_SECRET);
const id = decoded.userId;
const cipherText = CryptoJS.AES.encrypt(
bitBucketPassword,
process.env.CRYPTO_SECRET
);
await models.User.update(
{
bitBucketUsername,
bitBucketPassword: cipherText.toString()
},
{
where: { id }
}
);
res.json({});
});
router.get("/repos/:page", authCheck, async (req, res, next) => {
const page = req.params.page || 1;
const token = req.headers.authorization;
const decoded = jwt.verify(token, process.env.JWT_SECRET);
const id = decoded.userId;
const users = await models.User.findAll({ where: { id } });
const user = users[0];
const bytes = CryptoJS.AES.decrypt(
user.bitBucketPassword.toString(),
process.env.CRYPTO_SECRET
);
const password = bytes.toString(CryptoJS.enc.Utf8);
bitbucket.authenticate({
type: "basic",
username: user.bitBucketUsername,
password
});
let { data } = await bitbucket.repositories.list({
username: user.bitBucketUsername,
page,
sort: "-updated_on"
});
res.json(data);
});
router.get("/commits/:repoName", authCheck, async (req, res, next) => {
const token = req.headers.authorization;
const decoded = jwt.verify(token, process.env.JWT_SECRET);
const id = decoded.userId;
const users = await models.User.findAll({ where: { id } });
const user = users[0];
const repoName = req.params.repoName;
const bytes = CryptoJS.AES.decrypt(
user.bitBucketPassword.toString(),
process.env.CRYPTO_SECRET
);
const password = bytes.toString(CryptoJS.enc.Utf8);
bitbucket.authenticate({
type: "basic",
username: user.bitBucketUsername,
password
});
let { data } = await bitbucket.commits.list({
username: user.bitBucketUsername,
repo_slug: repoName,
sort: "-date"
});
res.json(data);
});
module.exports = router;
In each route, we get the user from the token, since we will add the user ID into the token, and from there we get the Bitbucket username and password, which we use to log into the Bitbucket API. Note that we have to decrypt the password since we encrypted it before saving it to the database.
We set the Bitbucket credentials in the setBitbucketCredentials route. We encrypt the password before saving to keep it secure.
Then in the repos route, we get the repos of the user and sort by reversed update_on order since we specified -updated_on in the sort parameter. The commits are listed in reverse date order since we specified -date in the sort parameter.
Next we add the user.js in the routes folder and add:
const express = require("express");
const models = require("../models");
const bcrypt = require("bcrypt");
const jwt = require("jsonwebtoken");
const querystring = require("querystring");
import { authCheck } from "../middlewares/authCheck";
const sgMail = require("@sendgrid/mail");
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const router = express.Router();
const rand = () => {
return Math.random()
.toString(36)
.substr(2);
};
const token = () => {
return rand() + rand();
};
router.post("/signup", async (req, res, next) => {
const { username, password } = req.body;
const hashedPassword = await bcrypt.hash(password, 10);
const verifyToken = token();
const user = await models.User.create({
username,
password: hashedPassword,
verifyToken
});
res.json(user);
});
router.post("/login", async (req, res, next) => {
const { username, password } = req.body;
const users = await models.User.findAll({ where: { username } });
const user = users[0];
const response = await bcrypt.compare(password, user.password);
if (response) {
const token = jwt.sign({ userId: user.id }, process.env.JWT_SECRET);
res.json({ token });
} else {
res.status(401).json({});
}
});
router.post("/changePassword", authCheck, async (req, res, next) => {
const { password } = req.body;
const token = req.headers.authorization;
const decoded = jwt.verify(token, process.env.JWT_SECRET);
const id = decoded.userId;
const hashedPassword = await bcrypt.hash(password, 10);
await models.User.update({ password: hashedPassword }, { where: { id } });
res.json({});
});
router.get("/currentUser", authCheck, async (req, res, next) => {
const token = req.headers.authorization;
const decoded = jwt.verify(token, process.env.JWT_SECRET);
const id = decoded.userId;
const users = await models.User.findAll({ where: { id } });
const { username, bitBucketUsername, verified } = users[0];
res.json({ username, bitBucketUsername, verified });
});
router.post("/sendVerificationEmail", authCheck, async (req, res, next) => {
const token = req.headers.authorization;
const decoded = jwt.verify(token, process.env.JWT_SECRET);
const id = decoded.userId;
const users = await models.User.findAll({ where: { id } });
const { username, verifyToken } = users[0];
const queryString = querystring.encode({
username,
verifyToken
});
const msg = {
to: username,
from: "bitbucketapp@bitbucketapp.com",
subject: "Verify Your Account",
html: `Hi ${username}, verify your email by clicking <a href='${process.env.FRONTEND_URL}/verify?${queryString}'>here</a>`,
text: `Hi ${username}, verify your email by going to ${process.env.FRONTEND_URL}/verify?${queryString}`
};
sgMail.send(msg);
res.json({});
});
router.get("/verify", async (req, res, next) => {
const { username, verifyToken } = req.query;
await models.User.update(
{ verified: true },
{ where: { username, verifyToken } }
);
res.json({});
});
module.exports = router;
We have routes for sign up, log in, and change password. We hash the password before saving when we sign up or changing password.
The currentUser route will be used for a settings form in the front end.
We also have the sendVerificationEmail route for send the verification email with the link. The link has the verifyToken that we generated when the user signs up and the user name. Since the username is unique, we can use it to set the verify flag for the right user.
In app.js we replace the existing code with:
require("dotenv").config();
var createError = require("http-errors");
var express = require("express");
var path = require("path");
var cookieParser = require("cookie-parser");
var logger = require("morgan");
const cors = require("cors");
var indexRouter = require("./routes/index");
var usersRouter = require("./routes/users");
var bitbucketRouter = require("./routes/bitbucket");
var app = express();
// view engine setup
app.set("views", path.join(__dirname, "views"));
app.set("view engine", "jade");
app.use(logger("dev"));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, "public")));
app.use(cors());
app.use("/", indexRouter);
app.use("/users", usersRouter);
app.use("/bitbucket", bitbucketRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get("env") === "development" ? err : {};
// render the error page
res.status(err.status || 500);
res.render("error");
});
module.exports = app;
to add the CORS add-on to enable cross domain communication, and add the users and bitbucket routes in our app by adding:
app.use("/users", usersRouter);
app.use("/bitbucket", bitbucketRouter);
This finishes the back end portion of the app. Now we can build the front end. We will build it with React, so we start by running npx create-react-app frontend from the project’s root folder.
Next we have to install some packages. We will install Bootstrap for styling, React Router for routing, Formik and Yup for form value handling and form validation respectively and Axios for making HTTP requests.
To do this run npm i axios bootstrap formik react-bootstrap react-router-dom yup to install all the packages.
Next we modify the App.js folder by replacing the existing code with the following:
import React from "react";
import HomePage from "./HomePage";
import "./App.css";
import ReposPage from "./ReposPage";
import CommitsPage from "./CommitsPage";
import SettingsPage from "./SettingsPage";
import { createBrowserHistory as createHistory } from "history";
import { Router, Route } from "react-router-dom";
import SignUpPage from "./SignUpPage";
import RequireAuth from "./RequireAuth";
import VerifyPage from "./VerifyPage";
const history = createHistory();
function App() {
return (
<div className="App">
<Router history={history}>
<Route path="/" exact component={HomePage} />
<Route path="/signup" exact component={SignUpPage} />
<Route path="/verify" exact component={VerifyPage} />
<Route
path="/settings"
component={props => (
<RequireAuth {...props} Component={SettingsPage} />
)}
/>
<Route
path="/repos"
exact
component={props => <RequireAuth {...props} Component={ReposPage} />}
/>
<Route
path="/commits/:repoName"
exact
component={props => (
<RequireAuth {...props} Component={CommitsPage} />
)}
/>
</Router>
</div>
);
}
export default App;
We add the routes for the pages in our app here. RequiredAuth is a higher order component which takes a component that requires authentication to access and return redirect if not authorized or the page if the user is authorized.
In App.css , we replace the existing code with:
.page {
padding: 20px;
}
to add some padding.
Next we add CommitsPage.js in the src folder and add:
import React, { useState, useEffect } from "react";
import { withRouter } from "react-router-dom";
import { commits, currentUser } from "./requests";
import Card from "react-bootstrap/Card";
import LoggedInTopBar from "./LoggedInTopBar";
const moment = require("moment");
function CommitsPage({ match: { params } }) {
const [initialized, setInitialized] = useState(false);
const [repoCommits, setRepoCommits] = useState([]);
const [notVerified, setNotVerified] = useState(true);
const getCommits = async page => {
const currentUserResponse = await currentUser();
if (!currentUserResponse.data.verified) {
return;
}
setNotVerified(false);
const repoName = params.repoName;
const response = await commits(repoName, page);
setRepoCommits(response.data.values);
};
useEffect(() => {
if (!initialized) {
getCommits(1);
setInitialized(true);
}
});
if (notVerified) {
return (
<div>
<LoggedInTopBar />
<h1 className="text-center">Your Repositories</h1>
<h2 className="text-center">You are not verified</h2>
</div>
);
}
return (
<>
<LoggedInTopBar />
<div className="page">
<h1 className="text-center">Commits</h1>
{repoCommits.map(rc => {
return (
<Card style={{ width: "90vw", margin: "0 auto" }}>
<Card.Body>
<Card.Title>{rc.message}</Card.Title>
<p>Message: {rc.author.raw}</p>
<p>
Date:{" "}
{moment(rc.date).format("dddd, MMMM Do YYYY, h:mm:ss a")}
</p>
<p>Hash: {rc.hash}</p>
</Card.Body>
</Card>
);
})}
</div>
</>
);
}
export default withRouter(CommitsPage);
We get the commits given the repository name in the URL parameter and display them in a list of Cards provided by React Bootstrap. In this page, we check if the user is verified before display anything with a call to currentUser in requests.js .
Next we create the Home Page, which lets us sign in. Create a HomePage.js file in the src folder and add:
import React, { useState, useEffect } from "react";
import { Formik } from "formik";
import Form from "react-bootstrap/Form";
import Col from "react-bootstrap/Col";
import Button from "react-bootstrap/Button";
import { Link } from "react-router-dom";
import * as yup from "yup";
import "./HomePage.css";
import { logIn } from "./requests";
import { Redirect } from "react-router-dom";
import Navbar from "react-bootstrap/Navbar";
import Nav from "react-bootstrap/Nav";
import LoggedOutTopBar from "./LoggedOutTopBar";
const schema = yup.object({
username: yup.string().email().required("Username must be an email"),
password: yup.string().required("Password is required")
});
function HomePage() {
const [redirect, setRedirect] = useState(false);
const handleSubmit = async evt => {
const isValid = await schema.validate(evt);
if (!isValid) {
return;
}
try {
const response = await logIn(evt);
localStorage.setItem("token", response.data.token);
setRedirect(true);
} catch (ex) {
alert("Invalid username or password");
}
};
if (redirect) {
return <Redirect to="/repos" />;
}
return (
<>
<LoggedOutTopBar />
<div className="page">
<h1 className="text-center">Log In</h1>
<Formik validationSchema={schema} onSubmit={handleSubmit}>
{({
handleSubmit,
handleChange,
handleBlur,
values,
touched,
isInvalid,
errors
}) => (
<Form noValidate onSubmit={handleSubmit}>
<Form.Row>
<Form.Group as={Col} md="12" controlId="username">
<Form.Label>Username</Form.Label>
<Form.Control
type="text"
name="username"
placeholder="Username"
value={values.username || ""}
onChange={handleChange}
isInvalid={touched.username && errors.username}
/>
<Form.Control.Feedback type="invalid">
{errors.username}
</Form.Control.Feedback>
</Form.Group>
<Form.Group as={Col} md="12" controlId="password">
<Form.Label>Password</Form.Label>
<Form.Control
type="password"
name="password"
placeholder="Password"
value={values.password || ""}
onChange={handleChange}
isInvalid={touched.password && errors.password}
/>
<Form.Control.Feedback type="invalid">
{errors.password}
</Form.Control.Feedback>
</Form.Group>
</Form.Row>
<Button type="submit" style={{ marginRight: "10px" }}>
Log In
</Button>
<Link
className="btn btn-primary"
to="/signup"
style={{ marginRight: "10px", color: "white" }}
>
Sign Up
</Link>
</Form>
)}
</Formik>
</div>
</>
);
}
export default HomePage;
We use the Formik component provided by Formik to get automatic form value handling. It will pipe the values directly to the parameter of the onSubmit handler. In the handleSubmit function, we run the schema.validate function to check for validity of the form values according to the schema object generated from the Yup library and if that’s successful, then we call login from the requests.js file which we will create.
Next we create the top bar. Create LoggedInTopBar.js in the src folder and add:
import React, { useState } from "react";
import Navbar from "react-bootstrap/Navbar";
import Nav from "react-bootstrap/Nav";
import { withRouter, Redirect } from "react-router-dom";
function LoggedInTopBar({ location }) {
const [redirect, setRedirect] = useState(false);
const { pathname } = location;
const isLoggedIn = () => !!localStorage.getItem("token");
if (redirect) {
return <Redirect to="/" />;
}
return (
<div>
{isLoggedIn() ? (
<Navbar bg="primary" expand="lg" variant="dark">
<Navbar.Brand href="#home">Bitbucket App</Navbar.Brand>
<Navbar.Toggle aria-controls="basic-navbar-nav" />
<Navbar.Collapse id="basic-navbar-nav">
<Nav className="mr-auto">
<Nav.Link href="/settings" active={pathname == "/settings"}>
Settings
</Nav.Link>
<Nav.Link href="/repos" active={pathname == "/repos"}>
Repos
</Nav.Link>
<Nav.Link>
<span
onClick={() => {
localStorage.clear();
setRedirect(true);
}}
>
Log Out
</span>
</Nav.Link>
</Nav>
</Navbar.Collapse>
</Navbar>
) : null}
</div>
);
}
export default withRouter(LoggedInTopBar);
This contains the React Bootstrap Navbar to show a top bar with a link to the home page and the name of the app. We only display it with the token present in local storage. We check the pathname to highlight the right links by setting the active prop.
We also need a simpler toolbar for the unauthenticated pages, we create LoggedOutToolbar.js and add:
import React, { useState } from "react";
import Navbar from "react-bootstrap/Navbar";
function LoggedOutTopBar() {
return (
<Navbar bg="primary" expand="lg" variant="dark">
<Navbar.Brand href="#home">Bitbucket App</Navbar.Brand>
</Navbar>
);
}
export default LoggedOutTopBar;
Next create ReposPage.js in the src folder to display the list of repositories the user owns. We add:
import React, { useState, useEffect } from "react";
import { repos, currentUser } from "./requests";
import Card from "react-bootstrap/Card";
import { Link } from "react-router-dom";
import Pagination from "react-bootstrap/Pagination";
import LoggedInTopBar from "./LoggedInTopBar";
function ReposPage() {
const [initialized, setInitialized] = useState(false);
const [repositories, setRepositories] = useState([]);
const [page, setPage] = useState(1);
const [totalPages, setTotalPages] = useState(1);
const [notVerified, setNotVerified] = useState(true);
const getRepos = async page => {
const currentUserResponse = await currentUser();
if (!currentUserResponse.data.verified) {
return;
}
setNotVerified(false);
const response = await repos(page);
setRepositories(response.data.values);
setTotalPages(Math.ceil(response.data.size / response.data.pagelen));
};
useEffect(() => {
if (!initialized) {
getRepos(1);
setInitialized(true);
}
});
if (notVerified) {
return (
<div>
<LoggedInTopBar />
<h1 className="text-center">Your Repositories</h1>
<h2 className="text-center">You are not verified</h2>
</div>
);
}
return (
<div>
<LoggedInTopBar />
<h1 className="text-center">Your Repositories</h1>
{repositories.map((r, i) => {
return (
<Card style={{ width: "90vw", margin: "0 auto" }} key={i}>
<Card.Body>
<Card.Title>{r.slug}</Card.Title>
<Link className="btn btn-primary" to={`/commits/${r.slug}`}>
Go
</Link>
</Card.Body>
</Card>
);
})}
<br />
<Pagination style={{ width: "90vw", margin: "0 auto" }}>
<Pagination.First onClick={() => getRepos(1)} />
<Pagination.Prev
onClick={() => {
let p = page - 1;
getRepos(p);
setPage(p);
}}
/>
<Pagination.Next
onClick={() => {
let p = page + 1;
getRepos(p);
setPage(p);
}}
/>
<Pagination.Last onClick={() => getRepos(totalPages)} />
</Pagination>
<br />
</div>
);
}
export default ReposPage;
We get the list repositories and we add pagination to get more repositories. In this page, we check if the user is verified before display anything with a call to currentUser in requests.js .
In requests.js , we add:
const axios = require("axios");
const APIURL = "http://localhost:3000";
axios.interceptors.request.use(
config => {
config.headers.authorization = localStorage.getItem("token");
return config;
},
error => Promise.reject(error)
);
axios.interceptors.response.use(
response => {
return response;
},
error => {
if (error.response && error.response.status == 401) {
localStorage.clear();
}
return Promise.reject(error);
}
);
export const signUp = data => axios.post(`${APIURL}/users/signup`, data);
export const logIn = data => axios.post(`${APIURL}/users/login`, data);
export const changePassword = data =>
axios.post(`${APIURL}/users/changePassword`, data);
export const currentUser = () => axios.get(`${APIURL}/users/currentUser`);
export const sendVerificationEmail = () =>
axios.post(`${APIURL}/users/sendVerificationEmail`);
export const verify = queryString =>
axios.get(`${APIURL}/users/verify?${queryString}`);
export const setBitbucketCredentials = data =>
axios.post(`${APIURL}/bitbucket/setBitbucketCredentials`, data);
export const repos = page =>
axios.get(`${APIURL}/bitbucket/repos/${page || 1}`);
export const commits = repoName =>
axios.get(`${APIURL}/bitbucket/commits/${repoName}`);
This file has all the HTTP requests that we make for sign up, log in, set credentials, get repositories and commits, etc.
And for handling responses, if we get 401 responses then we clear local storage so we won’t be using an invalid token. The code is below:
axios.interceptors.response.use(
response => {
return response;
},
error => {
if (error.response.status == 401) {
localStorage.clear();
}
return Promise.reject(error);
}
);
We attach the token to the request headers with:
axios.interceptors.request.use(
config => {
config.headers.authorization = localStorage.getItem("token");
return config;
},
error => Promise.reject(error)
);
so we don’t have to set it for each authenticated requests.
Next create a file called RequiredAuth.js in the src folder and add:
import React from "react";
import { Redirect } from "react-router-dom";
function RequireAuth({ Component }) {
if (!localStorage.getItem("token")) {
return <Redirect to="/" />;
}
return <Component />;
}
export default RequireAuth;
We check for presence of the token in the authenticated routes and render the Component prop passed in if the token is present.
Then we create a file called SettingsPage.js in the src folder and add:
import React, { useState, useEffect } from "react";
import { Formik } from "formik";
import Form from "react-bootstrap/Form";
import Col from "react-bootstrap/Col";
import Button from "react-bootstrap/Button";
import * as yup from "yup";
import {
currentUser,
setBitbucketCredentials,
changePassword
} from "./requests";
import LoggedInTopBar from "./LoggedInTopBar";
const userFormSchema = yup.object({
username: yup.string().required("Username is required"),
password: yup.string().required("Password is required")
});
const bitBucketFormSchema = yup.object({
bitBucketUsername: yup.string().required("Username is required"),
bitBucketPassword: yup.string().required("Password is required")
});
function SettingsPage() {
const [initialized, setInitialized] = useState(false);
const [user, setUser] = useState({});
const [bitbucketUser, setBitbucketUser] = useState({});
const handleUserSubmit = async evt => {
const isValid = await userFormSchema.validate(evt);
if (!isValid) {
return;
}
try {
await changePassword(evt);
alert("Password changed");
} catch (error) {
alert("Password change failed");
}
};
const handleBitbucketSubmit = async evt => {
const isValid = await bitBucketFormSchema.validate(evt);
if (!isValid) {
return;
}
try {

We have 2 forms. One for setting the password of the user and another for saving the Bitbucket credentials. We valid both in separate Yup schemas and make the request to back end if the data entered is valid.
Next we create the sign up page by creating SignUpPage.js in the src folder. We add:
import React, { useState, useEffect } from "react";
import { Formik } from "formik";
import Form from "react-bootstrap/Form";
import Col from "react-bootstrap/Col";
import Button from "react-bootstrap/Button";
import { Redirect } from "react-router-dom";
import * as yup from "yup";
import { signUp } from "./requests";
import Navbar from "react-bootstrap/Navbar";
import LoggedOutTopBar from "./LoggedOutTopBar";
const schema = yup.object({
username: yup.string().email().required("Username must be an email"),
password: yup.string().required("Password is required")
});
function SignUpPage() {
const [redirect, setRedirect] = useState(false);
const handleSubmit = async evt => {
const isValid = await schema.validate(evt);
if (!isValid) {
return;
}
try {
await signUp(evt);
setRedirect(true);
} catch (ex) {
alert("Username already taken");
}
};
if (redirect) {
return <Redirect to="/" />;
}
return (

export default SignUpPage;
It’s similar to the other log in request, except we call the sign up request instead of log in. We require the username field to be an email address so that we can send verification emails to the user.
Finally, in index.html , we replace the existing code with:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<link rel="apple-touch-icon" href="logo192.png" />
<!--
manifest.json provides metadata used when your web app is installed on a
user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
-->
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<!--
Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.

to add the Bootstrap CSS and change the title.
After writing all that code, we can run our app. First run back end by running npm start in the backend folder and npm start in the frontend folder, then choose ‘yes’ if you’re asked to run it from a different port.
