In any other case, be a part of us right here as we start by protecting the required stipulations earlier than leaping into step one of this Supabase authentication tutorial!
Stipulations
Earlier than getting began with this Supabase authentication tutorial, you could cope with 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 mission. 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 examine the ”Allow Row Stage Safety (RLS)” field:
From there, you could add two further columns: ”moralis_provider” set to ”varchar” and ”metadata” set to ”json”:
When you hit ”Save”, you must now have a brand new desk wanting one thing like this:
Lastly, the ultimate factor you could do is configure the RLS coverage for the desk. As such, click on on ”No lively RLS insurance policies” on the prime proper, adopted by ”New Coverage”:
You possibly can then go for the ”For full customization” possibility:
Add a coverage title, decide the ”SELECT” possibility, add ”authenticated” to the goal roles, and set the expression to ”true”:
If you click on on ”Evaluate”, your coverage ought to now look one thing like this:
Step 2: Cloning the Mission and Including Setting Variables
Now that you’ve got configured your Supabase database, allow us to dive into the precise mission. 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 mission to your native listing:
Full Supabase Authentication Docs – https://github.com/MoralisWeb3/Moralis-JS-SDK/tree/principal/demos/supabase-auth
Subsequent, with a neighborhood copy of the mission, you could make a number of configurations to the code. Begin by renaming the ”.env.instance” file to ”.env”. If you open this file, you’ll rapidly discover that you could add a number of surroundings variables:
SUPABASE_PUBLIC_ANON_KEY = ”
SUPABASE_SERVICE_KEY = ”
SUPABASE_URL = ”
# Your Moralis API key that may be discovered within the dashboard. Preserve 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 yow will discover the mission 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. Preserve 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 your complete mission to your native listing, you’ve all of the required code. Nonetheless, to make this extra comprehensible, the remaining steps will break down the important elements!
Step 3: Creating the Web3 Authentication Move
To start this code breakdown, allow us to begin by navigating to the ”authServices.ts” file, the place yow will discover the primary perform for the Web3 Supabase authentication stream:
export async perform requestMessage({ handle, chain, community }: { handle: string; chain: string; community: ‘evm’ }) {
const consequence = await Moralis.Auth.requestMessage({
handle,
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 perform is answerable 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 should be established. For this, we create the ”verifyMessage()” perform:
export async perform 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’,
position: ‘authenticated’,
exp: Math.ground(Date.now() / 1000) + 60 * 60 * 24 * 7,
},
config.SUPABASE_JWT,
);
return { person, token };
}
This perform makes use of the ”confirm()” perform from Moralis’ Auth API, passing ”community”, ”signature”, and ”message” as parameters. If the message is efficiently verified, the perform creates a JWT token and sends it to the frontend utility. As well as, earlier than issuing the token, the perform checks for a present person. If none exists, it creates a brand new one.
Step 5: Making the Consumer-Facet Implementing the Auth Move
Now, allow us to take a better 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()” perform:
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 perform 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 capabilities wanted for your complete Supabase authentication stream. From right here, we put all of it collectively within the ”handleAuth()” perform, which might 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 will 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. In case you have adopted alongside this far, you now know find out how to mix Web3 authentication with Supabase! Should you at any level skilled hassle, try the video on the prime of the tutorial or learn the Web3 Supabase documentation.

Easy methods to Authenticate Customers on Supabase – Closing Supabase Authentication App
Now that you’ve got accomplished the required configurations and understand how the code works, allow us to take a better take a look at the top outcomes. You will discover 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”. Should you click on on the previous, it’s going to 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 relating to all customers of the database:
Lastly, the ”Get customers as anon person” possibility illustrates that nameless customers will be unable to get the identical info. As a substitute, this can 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 tasks!
