@mio-xyz/sdk

Mio SDK for authentication and personalized context access. It helps your app exchange OAuth tokens and fetch Mio Context—structured facts about each user—from their existing tools (like email and calendar).

Installation

npm add @mio-xyz/sdk
yarn add @mio-xyz/sdk
pnpm add @mio-xyz/sdk

Quick Start

Backend usage (exchange authorization code for tokens)

import { Mio } from '@mio-xyz/sdk/server';

// Initialize once in your app (e.g. on server startup)
Mio.init({
  clientId: process.env.MIO_CLIENT_ID!,
  redirectUrl: process.env.MIO_REDIRECT_URL!,
  clientSecret: process.env.MIO_CLIENT_SECRET!
});

// In your API route
app.post('/api/exchange-token', async (req, res) => {
  const { code } = req.body;
  const mio = Mio.getInstance();
  const tokens = await mio.exchangeCodeForTokens(code);

  // Persist refreshToken if you want to refresh access tokens later
  // await saveTokensForUser(userId, tokens);

  res.json(tokens);
});

Frontend usage (Next.js / React)

Wrap your app with MioProvider to initialize the SDK once, then consume useMio anywhere in the tree.

// app/providers.tsx
'use client';

import type { ReactNode } from 'react';
import { MioProvider } from '@mio-xyz/sdk/react';
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
const mioConfig = {
  clientId: process.env.NEXT_PUBLIC_MIO_CLIENT_ID!,
  redirectUrl: `${process.env.NEXT_PUBLIC_APP_URL}/api/mio/callback`,
  exchangeTokenUrl: '/api/exchange-token'
};

export function Providers({ children }: { children: ReactNode }) {
  return <MioProvider config={mioConfig}>{children}</MioProvider>;
}

// app/chat/page.tsx
'use client';

import { useEffect, useState } from 'react';
import { useMio } from '@mio-xyz/sdk/react';

export default function ChatPage() {
  const { connect, handleMioCallback, getContext, isLoading, error } = useMio();
  const [accessToken, setAccessToken] = useState<string | null>(null);
  const [answer, setAnswer] = useState<string | null>(null);

  useEffect(() => {
    handleMioCallback()
      .then(tokens => {
        if (tokens?.accessToken) {
          setAccessToken(tokens.accessToken);
        }
      })
      .catch(() => {
        // Ignore when there is no `code` in the URL
      });
  }, [handleMioCallback]);

  const handleAsk = async () => {
    // You can choose to connect before the context request or in a separate button
    if (!accessToken) {
      await connect(); // kicks off OAuth if needed
      return;
    }

    const response = await getContext({
      query: 'How should we greet this user?',
      accessToken
    });

    setAnswer(response);
  };

  return (
    ...
  );
}

API Reference

Mio (frontend)

Frontend SDK for browser environments.

Methods

• init(config: MioClientSDKInitConfig) - Initialize the SDK singleton.
• getInstance() - Get the initialized SDK instance (throws if not initialized).
• connect() - Redirect to the Mio dashboard OAuth flow.
• exchangeCode(code) - Exchange an authorization code for tokens via your backend exchangeTokenUrl.
• getContext({ accessToken, query }) - Fetch Mio Context for a given user and query.
• getContextSummary({ accessToken }) - Fetch the latest Mio Context summary for the current user.

Mio (backend)

Backend SDK for server environments.

Methods

• init(config: MioServerSDKInitConfig) - Initialize the SDK singleton.
• getInstance() - Get the initialized SDK instance (throws if not initialized).
• exchangeCodeForTokens(code) - Exchange an authorization code for tokens using the client secret.
• refreshTokens(refreshToken) - Refresh access and refresh tokens using a refresh token.
• getContext({ accessToken, query }) - Fetch Mio Context for a user on the backend (batch jobs, workers, etc.).
• getContextSummary({ accessToken }) - Retrieve the current Mio Context summary from the context service.

useMio hook (frontend)

React hook for frontend integration.

Returns

• isLoading - Boolean indicating loading state
• error - Error message if any
• connect() - Function to initiate the OAuth flow
• handleMioCallback() - Function to handle the OAuth callback and exchange the code
• getContext({ accessToken, query }) - Fetch Mio Context for a user
• getContextSummary({ accessToken }) - Retrieve the current Mio Context summary for a user
