Space MVC

A TypeScript toolset to simplify building peer-to-peer applications using IPFS, Ethereum, and OrbitDb.

Our primary goals

• Provide a radically faster getting started experience for P2P app development.
• Make opinionated decisions to reduce boilerplate code.
• Implements simple, familiar MVC pattern.
• Serverless. In the real sense. There's no server.
• Easy to swap out new crypto technology. It changes so quickly.
• Apps work offline by default. Data is primarily stored in the user's browser.

SpaceMVC provides a pre-configured development environment with reasonable defaults. Start building real apps immediately.

Maintainable and Testable

• Object-oriented design and Inversify dependency injection helps you decouple your business logic and your UI to write maintainable and testable code.
• SpaceMVC relies heavily on Framework7 and the answers to many questions can be found in their excellent documentation. You can use it to build full featured iOS, Android & Desktop apps that look and feel native. It uses nothing but HTML, CSS, and Javascript.

Important Technology

• Typescript - TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.
• Framework7 - Build full featured iOS, Android & Desktop apps with HTML, CSS, and Javascript
• IPFS - A peer-to-peer hypermedia protocol designed to make the web faster, safer, and more open.
• OrbitDB - OrbitDB is a serverless, distributed, peer-to-peer database
• The Ethers Project - A complete Ethereum wallet implementation and utilities in JavaScript (and TypeScript).
• Inversify - IoC container Inversify.

Getting Started

The fastest way to create a project is to clone the TRY University project. //TODO: this will become a truffle box or similar

Installation

Add the following to your package.json

  "dependencies": {
    "space-mvc": "0.0.15-beta"
  }

Initialization

• Create Framework 7 parameters.
• Define OrbitDb data storage schema.
• Set up Inversify container with dependencies.

    import "core-js/stable"
    import "regenerator-runtime/runtime"

    import SpaceMVC from "space-mvc";

    import { container } from "./inversify.config"

    let f7Params = {
        root: '#app', // App root element
        id: 'example', // App bundle ID
        name: 'SpaceMVC Example', // App name
        theme: 'auto', // Automatic theme detection
    }

    let schema = [{
        name: "person", type: "mfsstore", load: 100, schema: {
            id: { unique: true },
            firstName: { unique: false },
            lastName: { unique: false }
        }
    }]

    await SpaceMVC.init( container, f7Params, "0x88bfEE1f69e83aa5F146B2B6F527878866D39fE9", schema)
