Synapse Framework

A zero-dependency, TypeScript-first fullstack web framework with strict enforcement of best practices, TDD, and design patterns. Built with Rust for maximum performance and Node.js for developer experience.

🚀 Features

• Zero Dependencies: Everything built from scratch in TypeScript and Rust
• Strict by Default: Enforce best practices at every level with no escape hatches
• TDD Mandatory: No code without tests - enforced at build time
• Multi-threaded: Leverage all available CPU cores with Rust backend
• Universal: Support any database, storage, hosting, protocol
• Extensible: Plugin system with strict guidelines and validation
• Type-Safe: Full TypeScript support with strict type checking
• High Performance: Rust-based compiler and bundler for maximum speed
• Developer Experience: Comprehensive CLI with all workflows

🏗️ Architecture

Core Components

• Runtime Engine: Multi-threaded Node.js runtime with worker pools
• Rust Compiler: High-performance TypeScript compiler written in Rust
• Rust Bundler: Parallel bundling and optimization engine
• Universal Router: File-based and programmatic routing
• State Management: Reactive state with strict immutability
• Testing Framework: Built-in TDD framework with 100% coverage enforcement
• Linting System: Custom linter with strict rules and auto-fix
• Plugin System: Extensible architecture with strict validation

🧪 Testing

TDD Enforcement

Synapse enforces Test-Driven Development by default:

// ❌ This will fail - no tests
export function calculateTotal(items: Item[]): number {
  return items.reduce((sum, item) => sum + item.price, 0);
}

// ✅ This will pass - has tests
export function calculateTotal(items: Item[]): number {
  return items.reduce((sum, item) => sum + item.price, 0);
}

// tests/calculateTotal.test.ts
import { calculateTotal } from '../src/calculateTotal';
import { expect, test } from '@synapse/testing';

test('calculateTotal should sum item prices', () => {
  const items = [
    { price: 10 },
    { price: 20 },
    { price: 30 }
  ];
  
  expect(calculateTotal(items)).toBe(60);
});

Test Commands

# Run all tests
synapse test

# Run tests in watch mode
synapse test:watch

# Run tests with coverage
synapse test --coverage

# Run specific test file
synapse test --pattern "**/*.test.ts"

# Run performance tests
synapse test:perf

🔍 Linting & Formatting

Strict Linting Rules

Synapse includes comprehensive linting rules:

// ❌ These will fail linting
const unused = 'variable';           // Unused variable
let mutable = 'value';               // Mutable variable
function bad() { return; }           // Missing return type
class Bad { prop = 1; }              // Missing access modifier

// ✅ These will pass linting
const used = 'variable';             // Used variable
const immutable = 'value';           // Immutable variable
function good(): string {            // Explicit return type
  return 'value';
}
class Good { 
  public prop = 1;                   // Explicit access modifier
}

Linting Commands

# Lint codebase
synapse lint

# Lint with auto-fix
synapse lint --fix

# Format code
synapse format

# Check formatting
synapse format --check

🗄️ Database Support

Universal Database Abstraction

import { Database } from '@synapse/database';

// Works with any database
const db = new Database({
  type: 'postgresql', // or 'mysql', 'sqlite', 'mongodb', etc.
  connectionString: process.env.DATABASE_URL
});

// Type-safe queries
const users = await db.query<User>('SELECT * FROM users WHERE age > ?', [18]);

// Migrations
await db.migrate();

// Seeding
await db.seed('users', userData);

Supported Databases

• SQL: PostgreSQL, MySQL, SQLite, SQL Server
• NoSQL: MongoDB, CouchDB, Redis
• Graph: Neo4j, ArangoDB
• Time-series: InfluxDB, TimescaleDB
• Search: Elasticsearch, Solr

🌐 Server Framework

Multiple Protocol Support

import { Server } from '@synapse/server';

const server = new Server({
  port: 3000,
  protocols: ['http', 'websocket', 'grpc', 'graphql']
});

// HTTP routes
server.get('/api/users', async (req, res) => {
  const users = await db.query('SELECT * FROM users');
  res.json(users);
});

// WebSocket
server.ws('/ws', (socket) => {
  socket.on('message', (data) => {
    socket.broadcast(data);
  });
});

// GraphQL
server.graphql(`
  type User {
    id: ID!
    name: String!
    email: String!
  }
  
  type Query {
    users: [User!]!
  }
`);

🔌 Plugin System

Creating Plugins

import { Plugin, PluginContext } from '@synapse/plugins';

export class MyPlugin implements Plugin {
  readonly id = 'my-plugin';
  readonly name = 'My Plugin';
  readonly version = '1.0.0';
  readonly dependencies = [];
  readonly hooks = [];
  readonly commands = [];
  readonly middleware = [];
  readonly components = [];

  async install(context: PluginContext): Promise<void> {
    // Plugin installation logic
  }

  async uninstall(context: PluginContext): Promise<void> {
    // Plugin uninstallation logic
  }
}

Plugin Commands

# Install plugin
synapse plugin:install @synapse/plugin-auth
