GoTrue Auth

If you've completed the Authentication section of The Tutorial, you've seen how you can add the Netlify Identity Widget to your Redwood app in a matter of minutes. But what do you do if you want to use Netlify Identity, but ditch the widget? There are many cases where we want much more control over our authentication interface and functionality, while still maintaining some ease-of-use when it comes to development.

Enter GoTrue-JS, a client library for interfacing with Netlify Identity's GoTrue API.

In this recipe, we'll:

But first, some housekeeping...

Prerequisites

Before getting started, there are a few steps you should have completed:

Enable Netlify Identity

Unless you've skipped the requirements section (for shame!), you should already have a Netlify account and a site set up. If you'd be so kind, navigate to your site's Dashboard, head to the Identity tab, and click Enable Identity:

Now you should see an Identity API endpoint, e.g. https://my-bodacious-app.netlify.app/.netlify/identity. Copy and paste that somewherewe'll need it in a moment when we instantiate GoTrue-JS.

Generate Auth Configuration

Let's start by installing the required packages and generating boilerplate code and files for Redwood Auth, all with this simple CLI command:

yarn redwood setup auth goTrue

By specifying goTrue as the provider, Redwood automatically added the necessary GoTrue-JS config to our App.js. Let's open up web/src/App.js and inspect. You should see:

web/src/App.js
import { AuthProvider } from '@redwoodjs/auth'
import GoTrue from 'gotrue-js'
import { FatalErrorBoundary } from '@redwoodjs/web'
import { RedwoodApolloProvider } from '@redwoodjs/web/apollo'

import FatalErrorPage from 'src/pages/FatalErrorPage'
import Routes from 'src/Routes'

import './index.css'

const goTrueClient = new GoTrue({
APIUrl: 'https://MYAPP.netlify.app/.netlify/identity',
setCookie: true,
})

const App = () => (
<FatalErrorBoundary page={FatalErrorPage}>
<AuthProvider client={goTrueClient} type="goTrue">
<RedwoodApolloProvider>
<Routes />
</RedwoodApolloProvider>
</AuthProvider>
</FatalErrorBoundary>
)

export default App

Time to use that API endpoint we copied from the Netlify Identity page. Replace the value of APIUrl with your API endpoint. For example:

web/src/App.js
// imports...

const goTrueClient = new GoTrue({
APIUrl: 'https://gotrue-recipe.netlify.app/.netlify/identity',
setCookie: true,
})

That's all for configuration. Easy!

Sign Up

Sign Up feels like an appropriate place to start building our interface.

Our first iteration won't include features like Email Confirmation or Password Recovery. Those, among other features, will be covered in the Advanced Concepts section of this recipe (coming soon).

To forego email confirmation, head back over to your site's Netlify Dashboard, open the Identity tab, and click Settings and usage.

In Emails > Confirmation template, click Edit settings, check Allow users to sign up without verifying their email address, and hit Save.

Netlify Identity Confirmation template

Nicely done. Now, back to our app.

The Sign Up Page

Let's generate a Sign Up page:

yarn redwood generate page Signup

This adds a Signup route to our routes file and creates a SignupPage component.

In the just-generated SignupPage component (web/src/pages/SignupPage/SignupPage.js), let's import some Redwood Form components and add a very basic form to our render component:

web/src/pages/SignupPage/SignupPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'

const SignupPage = () => {
return (
<>
<h1>Sign Up</h1>
<Form>
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</>
)
}

export default SignupPage

Did I mention it was basic? If you want to add some polish, you might find both the Redwood Form docs and the tutorial section on forms quite useful. For our purposes, let's just focus on the functionality.

Now that we have a form interface, we're going to want to do something when the user submits it. Let's add an onSubmit function to our component and pass it as a prop to our Form component:

web/src/pages/SignupPage/SignupPage.js
// imports...

const SignupPage = () => {
const onSubmit = (data) => {
// do something here
}

return (
<>
<h1>Sign Up</h1>
<Form onSubmit={onSubmit}>
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</>
)
}
//...

The something we need to do is—surprise!—sign up. To do this, we'll need a way to communicate with <AuthProvider /> and the GoTrue-JS client we passed to it. Look no further than the useAuth hook, which lets us subscribe to our auth state and its properties. In our case, we'll be glad to now have access to client and, thusly, our GoTrue-JS instance and all of its functions.

Let's import useAuth and destructure client from it in our component:

web/src/pages/SignupPage/SignupPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'

const SignupPage = () => {
const { client } = useAuth()

const onSubmit = (data) => {
// do something here
}

return (
<>
<h1>Sign Up</h1>
<Form onSubmit={onSubmit}>
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</>
)
}

export default SignupPage

And now we'll attempt to create a new user in the onSubmit function with client.signup() by passing in the email and password values that we've captured from our form:

web/src/pages/SignupPage/SignupPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'

const SignupPage = () => {
const { client } = useAuth()

const onSubmit = (data) => {
client
.signup(data.email, data.password)
.then((res) => console.log(res))
.catch((error) => console.log(error))
}

return (
<>
<h1>Sign Up</h1>
<Form onSubmit={onSubmit}>
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</>
)
}

export default SignupPage

Presently, our sign up will work as is, but simply console-logging the response from client.signup() is hardly useful behavior.

Let's display errors to the user if there is one. To do this, we'll set up React.useState() to manage our error state and conditionally render the error message if there is one. We'll also want to reset the error state at the beginning of every submission with setError(null):

web/src/pages/SignupPage/SignupPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'

const SignupPage = () => {
const { client } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
client
.signup(data.email, data.password)
.then((res) => console.log(res))
.catch((error) => setError(error.message))
}

return (
<>
<h1>Sign Up</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</>
)
}

export default SignupPage

Now we can handle a successful submission. Once a user has signed up, we should direct them to the sign in page that we'll be building out in the next section.

Start by generating a sign in page:

yarn redwood generate page Signin

Back in our SignupPage, let's import routes and navigate from Redwood Router and use them to redirect on successful sign up:

web/src/pages/SignupPage/SignupPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'
import { routes, navigate } from '@redwoodjs/router'

const SignupPage = () => {
const { client } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
client
.signup(data.email, data.password)
.then(() => navigate(routes.signin()))
.catch((error) => setError(error.message))
}

return (
<>
<h1>Sign Up</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</>
)
}

export default SignupPage

Hoorah! We've just added a sign up page and created a sign up form. We created a function to sign up users and we redirect users to the sign up page upon successful submission. Let's move on to Sign In.

Sign In

Let's get right to it. In the SigninPage we generated in the last section, let's add a basic form with email and password fields, some error reporting setup, and a hollow onSubmit function:

web/src/pages/SigninPage/SigninPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'

const SigninPage = () => {
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
// do sign in here
}

return (
<>
<h1>Sign In</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign In</Submit>
</Form>
</>
)
}

export default SigninPage

Then we'll need to import useAuth from @redwoodjs/auth and destructure logIn so that we can use it in our onSubmit function:

web/src/pages/SigninPage/SigninPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'

const SigninPage = () => {
const { logIn } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
// do sign in here
}

return (
<>
<h1>Sign In</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign In</Submit>
</Form>
</>
)
}

export default SigninPage

Now we'll add logIn to our onSubmit function. This time we'll be passing an object to our function as we're using Redwood Auth's logIn function directly (as opposed to client). This object takes an email, password, and a remember boolean. We'll also chain on then and catch to handle the response:

web/src/pages/SigninPage/SigninPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'

const SigninPage = () => {
const { logIn } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
logIn({ email: data.email, password: data.password, remember: true })
.then(() => {
// do something
})
.catch((error) => setError(error.message))
}

return (
<>
<h1>Sign In</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign In</Submit>
</Form>
</>
)
}

export default SigninPage

Now then, upon a successful login let's redirect our user back to the home page. First, generate a homepage (if you haven't already):

yarn redwood generate page Home /

In our SigninPage, import navigate and routes from @redwoodjs/router and add them to the then function:

web/src/pages/SigninPage/SigninPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'
import { navigate, routes } from '@redwoodjs/router'

const SigninPage = () => {
const { logIn } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
logIn({ email: data.email, password: data.password, remember: true })
.then(() => navigate(routes.home()))
.catch((error) => setError(error.message))
}

return (
<>
<h1>Sign In</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign In</Submit>
</Form>
</>
)
}

export default SigninPage

Well done! We've created a sign in page and form and we successfully handle sign in. Next up...

Sign Out

Sign out is by far the easiest auth functionality to implement: all we need to do is fire off useAuth's logOut method.

Let's start by generating a component to house our Sign Out Button:

yarn redwood generate component SignoutBtn

In the web/src/components/SignoutBtn/SignoutBtn.js file we just generated, let's render a button and add a click handler:

web/src/components/SignoutBtn/SignoutBtn.js
const SignoutBtn = () => {
const onClick = () => {
// do sign out here.
}
return <button onClick={() => onClick()}>Sign Out</button>
}

export default SignoutBtn

Now we can import useAuth from @redwoodjs/auth. We'll destructure its logOut method and invoke it in the onClick function:

web/src/components/SignoutBtn/SignoutBtn.js
import { useAuth } from '@redwoodjs/auth'

const SignoutBtn = () => {
const { logOut } = useAuth()

const onClick = () => {
logOut()
}

return <button onClick={() => onClick()}>Sign Out</button>
}

export default SignoutBtn

This works as is, but, because the user may be in a private area of your app when the Sign Out button is clicked, we should make sure we also navigate the user away from this page:

web/src/components/SignoutBtn/SignoutBtn.js
import { useAuth } from '@redwoodjs/auth'
import { navigate, routes } from '@redwoodjs/router'

const SignoutBtn = () => {
const { logOut } = useAuth()

const onClick = () => {
logOut().then(() => navigate(routes.home()))
}

return <button onClick={() => onClick()}>Sign Out</button>
}

export default SignoutBtn

And that's it for Sign Out! Err, of course, we're not rendering it anywhere in our app yet. In the next section, well add some navigation that conditionally renders the appropriate sign up, sign in, and sign out buttons based on our authentication state.

Here we'll implement some auth-related navigation that conditionally renders the correct links and buttons based on the user's authentication state.

  • When the user is not logged in, we should see Sign Up and Sign In.
  • When the user is logged in, we should see Log Out.

Let's start by generating a navigation component:

yarn redwood generate component Navigation

This creates web/src/components/Navigation/Navigation.js. In that file, let's import the Link component and the routes object from @redwoodjs/router.

We'll also import useAuth since we'll need to subscribe to the auth state in order for our components to decide what to render:

web/src/components/Navigation/Navigation.js
import { Link, routes } from '@redwoodjs/router'
import { useAuth } from '@redwoodjs/auth'

const Navigation = () => {
return <nav></nav>
}

export default Navigation

Let's destructure isAuthenticated from the useAuth API and apply it to some conditionals in the render method:

web/src/components/Navigation/Navigation.js
import { Link, routes } from '@redwoodjs/router'
import { useAuth } from '@redwoodjs/auth'

const Navigation = () => {
const { isAuthenticated } = useAuth()
return (
<nav>
{isAuthenticated ? (
// signed in - show the Sign Out button
) : (
// signed out - show the Sign Up and Sign In links
)}
</nav>
)
}

export default Navigation

Because Redwood Auth uses React's Context API to manage and broadcast the auth state, we can be confident that isAuthenticated will always be up-to-date, even if it changes from within another component in the tree (so long as it's a child of <AuthProvider />). In our case, when isAuthenticated changes, React will auto-magically take care of rendering the appropriate components.

So, now let's import our sign out button and add it, as well as sign in and sign up links, to the appropriate blocks in the conditional:

web/src/components/Navigation/Navigation.js
import { Link, routes } from '@redwoodjs/router'
import { useAuth } from '@redwoodjs/auth'
import SignoutBtn from 'src/components/SignoutBtn/SignoutBtn'

const Navigation = () => {
const { isAuthenticated } = useAuth()
return (
<nav>
{isAuthenticated ? (
<SignoutBtn />
) : (
<>
<Link to={routes.signup()}>Sign Up</Link>
<Link to={routes.signin()}>Sign In</Link>
</>
)}
</nav>
)
}

export default Navigation

We have a working navigation component, but we still need to render it somewhere. Let's generate a layout called GlobalLayout:

yarn redwood generate layout Global

Then import and render the navigation component in the newly generated web/src/layouts/GlobalLayout/GlobalLayout.js:

web/src/layouts/GlobalLayout/GlobalLayout.js
import Navigation from 'src/components/Navigation/Navigation'

const GlobalLayout = ({ children }) => {
return (
<>
<header>
<Navigation />
</header>
<main>{children}</main>
</>
)
}

export default GlobalLayout

Finally, we'll import and wrap each of our generated pages in this GlobalLayout component:

Home

web/src/pages/HomePage/Homepage.js
import GlobalLayout from 'src/layouts/GlobalLayout/GlobalLayout'

const HomePage = () => {
return (
<GlobalLayout>
<h1>Home</h1>
<p>My Gotrue Redwood Auth</p>
</GlobalLayout>
)
}

export default HomePage

Sign Up

web/src/pages/SignupPage/SignupPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'
import { routes, navigate } from '@redwoodjs/router'

import GlobalLayout from 'src/layouts/GlobalLayout/GlobalLayout'

const SignupPage = () => {
const { client } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
client
.signup(data.email, data.password)
.then(() => navigate(routes.signin()))
.catch((error) => setError(error.message))
}

return (
<GlobalLayout>
<h1>Sign Up</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign Up</Submit>
</Form>
</GlobalLayout>
)
}

export default SignupPage

Sign In

web/src/pages/SigninPage/SigninPage.js
import { Form, TextField, PasswordField, Submit } from '@redwoodjs/forms'
import { useAuth } from '@redwoodjs/auth'
import { navigate, routes } from '@redwoodjs/router'

import GlobalLayout from 'src/layouts/GlobalLayout/GlobalLayout'

const SigninPage = () => {
const { logIn } = useAuth()
const [error, setError] = React.useState(null)

const onSubmit = (data) => {
setError(null)
logIn({ email: data.email, password: data.password, remember: true })
.then(() => navigate(routes.home()))
.catch((error) => setError(error.message))
}

return (
<GlobalLayout>
<h1>Sign In</h1>
<Form onSubmit={onSubmit}>
{error && <p>{error}</p>}
<TextField name="email" placeholder="email" />
<PasswordField name="password" placeholder="password" />
<Submit>Sign In</Submit>
</Form>
</GlobalLayout>
)
}

export default SigninPage

Now we have navigation that renders the correct links and buttons based on our auth state. When the user signs in, they'll see a Sign Out button. When the user signs out, they'll see Sign Up and Sign In links.

Wrapping Up

We've configured GoTrue with Redwood Auth, created a Sign Up page, a Sign In page, a Sign Out button, and added auth links to our layout. Nicely done!

Thanks for tuning in!
