In any other case, be a part of us right here as we start by overlaying the required stipulations earlier than leaping into step one of this Supabase authentication tutorial!
Conditions
Earlier than getting began with this Supabase authentication tutorial, it is advisable to take care of the next stipulations:
Set up the Moralis and Supabase SDKs – Open a brand new terminal and run the next command: yarn add moralis @supabase/supabase-js jsonwebtoken
Step 1: Setting Up Supabase
Step one is to arrange a brand new Supabase venture. To take action, log in to Supabase and click on on the ”+ New Mission” button:
Fill in a reputation, choose a password, area, and pricing plan:
Subsequent, go to ”Desk editor”, select ”public” for the schema, and hit the ”Create a brand new desk” button:
Add a reputation and outline, and make sure you verify the ”Allow Row Degree Safety (RLS)” field:
From there, it is advisable to add two extra columns: ”moralis_provider” set to ”varchar” and ”metadata” set to ”json”:
When you hit ”Save”, it is best to now have a brand new desk trying one thing like this:
Lastly, the ultimate factor it is advisable to do is configure the RLS coverage for the desk. As such, click on on ”No energetic RLS insurance policies” on the high proper, adopted by ”New Coverage”:
You possibly can then go for the ”For full customization” choice:
Add a coverage title, choose the ”SELECT” choice, add ”authenticated” to the goal roles, and set the expression to ”true”:
While you click on on ”Assessment”, your coverage ought to now look one thing like this:
Step 2: Cloning the Mission and Including Surroundings Variables
Now that you’ve got configured your Supabase database, allow us to dive into the precise venture. To make this Supabase authentication tutorial as easy as potential, we’ll use a pre-made app. So, the primary order of enterprise is visiting the GitHub repository beneath and cloning the venture to your native listing:
Full Supabase Authentication Docs – https://github.com/MoralisWeb3/Moralis-JS-SDK/tree/foremost/demos/supabase-auth
Subsequent, with a neighborhood copy of the venture, it is advisable to make a number of configurations to the code. Begin by renaming the ”.env.instance” file to ”.env”. While you open this file, you’ll shortly discover that it is advisable to add a number of setting variables:
SUPABASE_PUBLIC_ANON_KEY = ”
SUPABASE_SERVICE_KEY = ”
SUPABASE_URL = ”
# Your Moralis API key that may be discovered within the dashboard. Hold this secret!
MORALIS_API_KEY = ”
PORT = 3000
APP_NAME = ‘supabase-demo’
SUPABASE_JWT = ”
First, go to the Supabase dashboard, and click on on ”Mission Settings”, adopted by ”API”. Right here you will discover the venture URL, API keys, and the JWT secret:
Allow us to copy every worth and add them to the code. It ought to now look one thing like this:
SUPABASE_PUBLIC_ANON_KEY = ‘eyJhb…’
SUPABASE_SERVICE_KEY = ‘eyJhb…’
SUPABASE_URL = ‘https://cscaffczpobedyxjwujy.supabase.co’
# Your Moralis API key that may be discovered within the dashboard. Hold this secret!
MORALIS_API_KEY = ”
PORT = 3000
APP_NAME = ‘supabase-demo’
SUPABASE_JWT = ‘o5+4…’
Lastly, you additionally want so as to add your Moralis API key to the ”MORALIS_API_KEY” variable. To seek out your key, log in to Moralis and click on on the ”Web3 APIs” tab:
Because you copied the complete venture to your native listing, you’ve got all of the required code. Nonetheless, to make this extra comprehensible, the remaining steps will break down the important components!
Step 3: Creating the Web3 Authentication Circulation
To start this code breakdown, allow us to begin by navigating to the ”authServices.ts” file, the place you will discover the primary operate for the Web3 Supabase authentication stream:
export async operate requestMessage({ tackle, chain, community }: { tackle: string; chain: string; community: ‘evm’ }) {
const consequence = await Moralis.Auth.requestMessage({
tackle,
chain,
community,
area: ‘defi.finance’,
assertion: ‘Please signal this message to verify your id.’,
uri: ‘https://defi.finance’,
expirationTime: ‘2023-01-01T00:00:00.000Z’,
timeout: 15,
});
const { message } = consequence.toJSON();
return message;
}
This operate is liable for requesting a message from Moralis’ Auth API. It permits us to ship a message to the customers, prompting them to signal it utilizing their MetaMask pockets.
Step 4: Verifying the Message
Since we’re asking customers to signal a message, verification of the signature have to be established. For this, we create the ”verifyMessage()” operate:
export async operate verifyMessage({ community, signature, message }: VerifyMessage) {
const consequence = await Moralis.Auth.confirm({
community,
signature,
message,
});
const authData = consequence.toJSON();
let { knowledge: person } = await supabase.from(‘customers’).choose(‘*’).eq(‘moralis_provider_id’, authData.profileId).single();
if (!person) {
const response = await supabase
.from(‘customers’)
.insert({ moralis_provider_id: authData.profileId, metadata: authData })
.single();
person = response.knowledge;
}
const token = jwt.signal(
{
…person,
aud: ‘authenticated’,
function: ‘authenticated’,
exp: Math.flooring(Date.now() / 1000) + 60 * 60 * 24 * 7,
},
config.SUPABASE_JWT,
);
return { person, token };
}
This operate makes use of the ”confirm()” operate from Moralis’ Auth API, passing ”community”, ”signature”, and ”message” as parameters. If the message is efficiently verified, the operate creates a JWT token and sends it to the frontend utility. As well as, earlier than issuing the token, the operate checks for a present person. If none exists, it creates a brand new one.
Step 5: Making the Consumer-Facet Implementing the Auth Circulation
Now, allow us to take a more in-depth take a look at the client-side implementing the authentication stream, beginning with the ”index.html” file. On this file, we start by including dependencies utilizing CDN for “axios“, ethers.js, and the Supabase SDK:
Subsequent, go to ”script.js” so as to add your Supabase URL and anon key (go to Supabase, click on on ”Mission Settings”, and choose the ”API” tab to get these values):
Additional down in ”script.js”, we add the ”connectToMetamask()” operate:
const connectToMetamask = async () => {
const supplier = new ethers.suppliers.Web3Provider(window.ethereum, ‘any’);
const [accounts, chainId] = await Promise.all([
provider.send(‘eth_requestAccounts’, []),
supplier.ship(‘eth_chainId’, []),
]);
const signer = supplier.getSigner();
return { signer, chain: chainId, account: accounts[0] };
};
This operate makes use of a regular ethers.js supplier to attach with MetaMask. What’s extra, it fetches primary knowledge concerning the person’s pockets.
That covers the required features wanted for the complete Supabase authentication stream. From right here, we put all of it collectively within the ”handleAuth()” operate, which may look one thing like this:
const handleAuth = async () => {
// Hook up with MetaMask
const { signer, chain, account } = await connectToMetamask();
if (!account) {
throw new Error(‘No account discovered’);
}
if (!chain) {
throw new Error(‘No chain discovered’);
}
const { message } = await requestMessage(account, chain);
const signature = await signer.signMessage(message);
const { person } = await verifyMessage(message, signature);
_supabaseAuthenticated = supabase.createClient(SUPABASE_URL, SUPABASE_PUBLIC_ANON_KEY, {
world: {
headers: {
Authorization: `Bearer ${person.token}`,
},
},
});
renderUser(person);
};
After a person authenticates with this Supabase consumer, we are able to now entry the customers’ desk utilizing the token returned after verification:
const getUser = async (token) => {
const { knowledge } = await _supabaseAuthenticated.from(‘customers’).choose(‘*’);
renderUser(knowledge);
};
Congratulations! That’s it for this Supabase authentication tutorial. If in case you have adopted alongside this far, you now know methods to mix Web3 authentication with Supabase! For those who at any level skilled hassle, try the video on the high of the tutorial or learn the Web3 Supabase documentation.
Now, earlier than concluding this tutorial, allow us to take a more in-depth take a look at the outcomes of the Supabase authentication tutorial!
Tips on how to Authenticate Customers on Supabase – Remaining Supabase Authentication App
Now that you’ve got accomplished the required configurations and know the way the code works, allow us to take a more in-depth take a look at the top outcomes. You’ll find the app’s touchdown web page down beneath:
The app options three buttons: ”Authenticate by way of MetaMask”, ”Get customers as authenticated person”, and ”Get customers as anon person”. For those who click on on the previous, it’ll routinely set off your MetaMask pockets, requiring you to signal a message:
When you signal the message, the code creates a JWT to confirm if a person exists. If the person is nonexistent, we create a brand new one and add it to the Supabase database:
With the ”Get customers as authenticated person” button, solely authenticated customers will have the ability to get info concerning all customers of the database:
Lastly, the ”Get customers as anon person” choice illustrates that nameless customers will be unable to get the identical info. As a substitute, it will solely show an empty array:
That’s it for this Supabase authentication tutorial! Now you can comply with the identical steps to implement comparable performance into future Web3 initiatives!
