Mere Memory

An implementation of simple byte storage for including in Holochain DNAs.

Overview

Features

• Breakdown large objects into 2MB or less (2,097,152 bytes)
• Lookup memory by hash

Usage

Include mere_memory WASMs in DNA

Example using Mere Memory zomes in a DNA manifest (example)

manifest_version: "1"
name: storage
integrity:
  uid: "00000000-0000-0000-0000-000000000000"
  properties: ~
  origin_time: "2022-07-21T00:00:00.000000Z"
  zomes:
    - name: mere_memory
      bundled: ./path/to/mere_memory.wasm
    # ...other integrity zomes
coordinator:
  zomes:
    - name: mere_memory_api
      bundled: ./path/to/mere_memory_api.wasm
      dependencies:
        - name: mere_memory
    # ...other coordinator zomes

Example using @spartan-hc/app-interface-client

NOTES: replace APP_PORT, APP_ID, and DNA_NAME with runtime specific values.

import { AppInterfaceClient } from '@spartan-hc/app-interface-client';
import { MereMemoryZomelet } from '@spartan-hc/mere-memory-zomelets';

const client = new AppInterfaceClient( APP_PORT );
const app_client = await client.app( APP_ID );

const cell = app_client.createCellInterface( DNA_NAME, {
    "mere_memory_api": MereMemoryZomelet,
});

const mere_memory = cell.zomes.mere_memory_api.functions;

let addr = await mere_memory.save( bytes );
// EntryHash
let memory = await mere_memory.remember( addr );
// {
