Memory Graph

Memory Graph is a React component that visualizes your Supermemory documents and memories as an interactive network. Documents appear as rectangular nodes, memories as hexagonal nodes, and connections between them show relationships and similarity.

Installation

npm install @supermemory/memory-graph

Requirements: React 18.0.0 or higher

Quick start

'use client'; // For Next.js App Router

import { MemoryGraph } from '@supermemory/memory-graph';
import type { DocumentWithMemories } from '@supermemory/memory-graph';
import { useEffect, useState } from 'react';

export default function GraphPage() {
  const [documents, setDocuments] = useState<DocumentWithMemories[]>([]);
  const [isLoading, setIsLoading] = useState(true);
  const [error, setError] = useState<Error | null>(null);

  useEffect(() => {
    fetch('/api/graph')
      .then(res => res.json())
      .then(data => {
        setDocuments(data.documents);
        setIsLoading(false);
      })
      .catch(err => {
        setError(err);
        setIsLoading(false);
      });
  }, []);

  return (
    <div style={{ height: '100vh' }}>
      <MemoryGraph
        documents={documents}
        isLoading={isLoading}
        error={error}
        variant="console"
      />
    </div>
  );
}

Existing icon-based document nodes and connection styling remain the defaults. Opt in to stacked squares and stronger semantic connections with appearance:

<MemoryGraph
  documents={documents}
  appearance={{ documentNodes: 'stacked', connections: 'emphasized' }}
  openDocumentOnEnter
  onOpenDocument={openPersistedDocument}
/>

documentNodes accepts 'icons' or 'stacked'; connections accepts 'default' or 'emphasized'. Both fields are optional and also work on GraphCanvas. Stacks stay inside existing node bounds and simplify at low zoom. Use colors.edgeDocument to configure document-source ink; older custom GraphCanvas palettes without that field use textSecondary in emphasized mode. openDocumentOnEnter is off by default. With an onOpenDocument callback, MemoryGraph exposes a focused Enter action for the selected persisted document or one confirmed memory source. Typing, modifier shortcuts, repeats, composition and keys outside the graph do not open documents. Your callback retains responsibility for routing and access control; consumers without a callback receive no new opening behavior.

Backend API route

Create an API route to fetch documents from Supermemory:

// app/api/graph/route.ts
import { NextResponse } from 'next/server';

export async function GET() {
  const response = await fetch('https://api.supermemory.ai/v3/documents/documents', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
    },
    body: JSON.stringify({
      page: 1,
      limit: 500,
      sort: 'createdAt',
      order: 'desc',
    }),
  });

  const data = await response.json();
  return NextResponse.json(data);
}

// pages/api/graph.ts
import type { NextApiRequest, NextApiResponse } from 'next';

export default async function handler(req: NextApiRequest, res: NextApiResponse) {
  const response = await fetch('https://api.supermemory.ai/v3/documents/documents', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
    },
    body: JSON.stringify({ page: 1, limit: 500, sort: 'createdAt', order: 'desc' }),
  });

  const data = await response.json();
  res.json(data);
}

app.get('/api/graph', async (req, res) => {
  const response = await fetch('https://api.supermemory.ai/v3/documents/documents', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.SUPERMEMORY_API_KEY}`,
    },
    body: JSON.stringify({ page: 1, limit: 500, sort: 'createdAt', order: 'desc' }),
  });

  const data = await response.json();
  res.json(data);
});

Never expose your Supermemory API key to the client. Always fetch data through your backend.

Variants

Console Variant - Full-featured dashboard view (0.8x zoom, space selector visible):

<MemoryGraph documents={documents} variant="console" />

Consumer Variant - Embedded widget view (0.5x zoom, space selector hidden):

<MemoryGraph documents={documents} variant="consumer" />

Examples

With pagination

'use client';

import { MemoryGraph } from '@supermemory/memory-graph';
import { useCallback, useEffect, useState } from 'react';

export default function PaginatedGraph() {
  const [documents, setDocuments] = useState([]);
  const [page, setPage] = useState(1);
  const [hasMore, setHasMore] = useState(true);
  const [isLoading, setIsLoading] = useState(true);
  const [isLoadingMore, setIsLoadingMore] = useState(false);

  useEffect(() => { fetchPage(1, false); }, []);

  const fetchPage = async (pageNum, append) => {
    pageNum === 1 ? setIsLoading(true) : setIsLoadingMore(true);

    const res = await fetch(`/api/graph?page=${pageNum}&limit=100`);
    const data = await res.json();

    append ? setDocuments(prev => [...prev, ...data.documents]) : setDocuments(data.documents);
    setHasMore(data.pagination.currentPage < data.pagination.totalPages);
    setIsLoading(false);
    setIsLoadingMore(false);
  };

  const loadMore = useCallback(async () => {
    if (!isLoadingMore && hasMore) {
      const nextPage = page + 1;
      setPage(nextPage);
      await fetchPage(nextPage, true);
    }
  }, [page, hasMore, isLoadingMore]);

  return (
    <MemoryGraph
      documents={documents}
      isLoading={isLoading}
      isLoadingMore={isLoadingMore}
      hasMore={hasMore}
      totalLoaded={documents.length}
      loadMoreDocuments={loadMore}
    />
  );
}

Highlighting search results

<MemoryGraph
  documents={documents}
  highlightDocumentIds={searchResults}
  highlightsVisible={searchResults.length > 0}
/>

Controlled space selection

<MemoryGraph
  documents={documents}
  selectedSpace={selectedSpace}
  onSpaceChange={setSelectedSpace}
  showSpacesSelector={false}
/>

Custom empty state

<MemoryGraph documents={documents} isLoading={isLoading}>
  <div style={{ textAlign: 'center', padding: '2rem' }}>
    <h2>No memories yet</h2>
    <p>Add content to see your knowledge graph</p>
  </div>
</MemoryGraph>

Performance

The graph handles hundreds of nodes efficiently through:

Canvas-based rendering (not DOM elements)
Viewport culling (only draws visible nodes)
Level-of-detail optimization (simplifies when zoomed out)
Change-based rendering (only redraws when state changes)

For very large datasets (1000+ documents), use pagination to load data in chunks.

Browser support

Works in all modern browsers supporting Canvas 2D API, ES2020, and CSS custom properties. Tested on Chrome, Firefox, Safari, and Edge.
