Magic.Link Authentication

Installation

The following CLI command will install required packages and generate boilerplate code and files for Redwood Projects:

yarn rw setup auth magicLink

If you prefer to manually install the package and add code, run the following command and then add the required code provided in the next section.

cd web
yarn add @redwoodjs/auth magic-sdk

Setup

To get your application keys, go to dashboard.magic.link then navigate to the API keys add them to your .env.

Including Environment Variables in Serverless Deployment: in addition to adding the following env vars to your deployment hosting provider, you must take an additional step to include them in your deployment build process. Using the names exactly as given below, follow the instructions in this document to "Whitelist them in your redwood.toml".

web/src/App.js|tsx
import { useAuth, AuthProvider } from '@redwoodjs/auth'
import { Magic } from 'magic-sdk'
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 m = new Magic(process.env.MAGICLINK_PUBLIC)

const App = () => (
<FatalErrorBoundary page={FatalErrorPage}>
<AuthProvider client={m} type="magicLink">
<RedwoodApolloProvider useAuth={useAuth}>
<Routes />
</RedwoodApolloProvider>
</AuthProvider>
</FatalErrorBoundary>
)

export default App
web/src/Routes.js|tsx
import { useAuth } from '@redwoodjs/auth'
import { Router, Route } from '@redwoodjs/router'

const Routes = () => {
return (
<Router useAuth={useAuth}>
<Route path="/" page={HomePage} name="home" />
<Route notfound page={NotFoundPage} />
</Router>
)
}

export default Routes

Integration

The Redwood API does not include the functionality to decode Magic.link authentication tokens, so the client is initiated and decodes the tokens inside of getCurrentUser.

Installation

First, you must manually install the Magic Admin SDK in your project's api/package.json.

yarn workspace api add @magic-sdk/admin

Setup

To get your application running without setting up Prisma, get your SECRET KEY from dashboard.magic.link. Then add MAGICLINK_SECRET to your .env.

redwood/api/src/lib/auth.js|ts
import { Magic } from '@magic-sdk/admin'

export const getCurrentUser = async (_decoded, { token }) => {
const mAdmin = new Magic(process.env.MAGICLINK_SECRET)

return await mAdmin.users.getMetadataByToken(token)
}

Magic.link recommends using the issuer as the userID to retrieve user metadata via Prisma

redwood/api/src/lib/auth.ts
import { Magic } from '@magic-sdk/admin'

export const getCurrentUser = async (_decoded, { token }) => {
const mAdmin = new Magic(process.env.MAGICLINK_SECRET)
const { email, publicAddress, issuer } = await mAdmin.users.getMetadataByToken(token)

return await db.user.findUnique({ where: { issuer } })
}
