Large Core

Large Core is a library that helps you built P2P Typescript apps using IPFS, OrbitDB, and Ethereum.

It provides:

• A configured OrbitDB instance.

• An ethers.js Ethereum wallet.

• Pre-built data services

  • Profile Service - Each wallet has a user profile. Use the default or expand it with other fields.
  • Friend Service - Follow other users. Automatically get updates to their posts and profiles.
  • Read Only Post Service - Load a large feed of posts and easily page through it. It's very lazily-loaded. Posts can not be edited.
  • Blog Post Service - A post service that allows for posts to be updated. Can still be paged through without loading all of the content. Loads a bit more data than the read only post service.
  • Page Service - Manage static pages.
  • Group Service - Not available yet. Will manage groups.
  • Schema Service - Each Large instance has a schema that it adheres to.
  • Wallet Service - Used in cases where MetaMask is not available.
  • Site Settings Service - Basic info about the website.
  • Feed Monitor Service - Manages subscriptions to various post feeds. Listens for updates to all feeds and puts any posts it finds into the user's main feed.

• Works in the browser, Electron, and (soon) Android/iOS.

  • Use MetaMask or a built-in wallet instead.

• Data is stored in IPFS and OrbitDB. Right now all data is unencrypted. This will likely change.

• Ethereum is used to authenticate messages.
