@tame basin how do I implement authentification using react, nodejs and convex ? To be clear , sometimes I want to wrap some logic in nodejs , like doing some post api calls, and nodejs would be connected to convex, same as react (connected to convex)

Let me check the knowledge base for you. One moment! :books:
To implement authentication in a project using React, Node.js, and Convex, you can follow these steps:
- Setup Convex in Node.js: Follow the Node.js Quickstart guide (https://docs.convex.dev/quickstart/nodejs) to set up Convex in your Node.js project. This involves creating a new npm project, installing the Convex client and server library, setting up a Convex dev deployment, and creating sample data for your database.
mkdir my-project && cd my-project && npm init -y && npm pkg set type="module"
npm install convex dotenv
npx convex dev
- Setup Convex in React: Follow the React Quickstart guide (https://docs.convex.dev/quickstart/react) to set up Convex in your React project. This involves installing the Convex npm package and connecting to a backend.
npm install convex
Then, create an instance of the Convex client and make it available to your app:
import { ConvexProvider, ConvexReactClient } from "convex/react";
const convex = new ConvexReactClient("<https://<your> domain here>.convex.cloud");
reactDOMRoot.render(
<React.StrictMode>
<ConvexProvider client={convex}>
<App />
</ConvexProvider>
</React.StrictMode>,
);
- Implement Authentication: Convex recommends using a third-party auth provider like Clerk (https://docs.convex.dev/auth/clerk) or Auth0 (https://docs.convex.dev/auth/auth0) to handle user authentication. You can follow the respective guides to set up authentication in your app. For example, if you're using Clerk, you can create a
ConvexProvider.tsfile to wrap your app with:
'use client';
import { ReactNode } from 'react';
import { ConvexReactClient } from 'convex/react';
import { ConvexProviderWithClerk } from 'convex/react-clerk';
import { ClerkProvider, useAuth } from '@clerk/nextjs';const convex = new ConvexReactClient(process.env.NEXT_PUBLIC_CONVEX_URL!);
export default function ConvexClientProvider({
children,
}: {
children: ReactNode;
}) {
return (
<ClerkProvider
publishableKey={process.env.NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY!}
<ConvexProviderWithClerk client={convex} useAuth={useAuth}>
{children}
</ConvexProviderWithClerk>
</ClerkProvider>
);
}
Remember to check out the **Convex Quickstart** (<https://docs.convex.dev/quickstart/nextjs>) and the **Convex Clerk** (<https://docs.convex.dev/auth/clerk>) auth section for more details.
For the Node.js part, you would need to use the Convex client's `setAuth` method to set the authentication. Unfortunately, the provided knowledge sources do not provide a specific example of how to do this with Clerk or any other authentication provider. You may need to refer to the **Convex API documentation** (<https://docs.convex.dev/api/classes/browser.ConvexClient#setauth>) or ask for further assistance in the Convex community.

----------------------@tame basin is there a way to get some sort of token from react clerk in the client side, and then using nodejs with convex to get the user info from it ?

Let me check the knowledge base for you. One moment! :books:
Yes, you can get a JWT token from Clerk on the client side (React) and then use it on the server side (Node.js) with Convex to get the user info. Here's how you can do it:
- Get the JWT token from Clerk in React: You can use the
getTokenmethod from Clerk'suseAuthhook to get the JWT token. Here's an example:
import { useAuth } from "@clerk/clerk-react";
// Inside a React component
const { getToken } = useAuth();
const token = await getToken({ template: "convex" });

- Use the JWT token in Node.js with Convex: Once you have the JWT token, you can send it to your Node.js server (for example, as a header in a fetch request). On the server side, you can use the
setAuthmethod of the Convex client to authenticate your requests:
const convex = new ConvexHttpClient(process.env.NEXT_PUBLIC_CONVEX_URL ?? "");
convex.setAuth(token);

Remember to replace "convex" with the actual template name you're using in Clerk, and replace process.env.NEXT_PUBLIC_CONVEX_URL with your actual Convex URL.
Please note that the provided knowledge sources do not provide a specific example of how to pass the token from the client to the server. You may need to implement this part according to your application's requirements and architecture.

@tame basin what would the convex.setAuth return ?
tame basinBOT
Let me check the knowledge base for you. One moment! :books:
The setAuth method in Convex does not return any value. It's a void function, meaning it performs an action but does not return anything.
In the context of Convex, the setAuth method is used to set the authentication token to be used for subsequent queries and mutations. It should be called whenever the token changes, for example due to expiration and refresh.
Here's the method signature for setAuth in the Convex client:
setAuth(fetchToken, onChange?): void
And for the Convex HTTP client:
setAuth(value): void
You can find more details in the Convex API documentation (https://docs.convex.dev/api/classes/browser.ConvexClient#setauth).

@tame basin how do I know then that the token is correct
tame basinBOT
Let me check the knowledge base for you. One moment! :books:
To verify that the token is correct, you can use the getUserIdentity function provided by Convex. This function will return the user's identity if the token is valid, or null if it's not. Here's an example:
const userIdentity = await convex.getUserIdentity();
If userIdentity is not null, then the token is valid. If it's null, then the token is not valid or the user is not authenticated.
Please note that this function should be used in a try-catch block to handle any potential errors.
You can also use online JWT decoders like jwt.io (https://jwt.io/) to check if the token is a valid JWT. However, this won't tell you if the token is valid for your Convex backend, only if it's a correctly formatted JWT.
Remember to check the Convex documentation (https://docs.convex.dev/auth/debug#step-3-check-that-backend-configuration-matches-frontend-configuration) for more details on debugging authentication issues.
