cache

• get cache(): MemoryCache

  Access the in-memory key-value cache.

  The cache allows storing and retrieving JSON-serializable values that persist across handler invocations. Useful for caching computed results, tracking cumulative state, or storing intermediate processing data.

  Returns MemoryCache

  The MemoryCache instance, or undefined if cache is not available

  Example

  // Store and retrieve values
  await ctx.cache.set('totalVolume', volume)
  const cached = await ctx.cache.get<number>('totalVolume')
  
  // Block-scoped values (isolated per block)
  await ctx.cache.setInBlock('blockCount', count)
  Copy
