Code Features Overview

This directory contains reusable code snippets and complete examples demonstrating specific BSV blockchain functionality. These code features are used as building blocks throughout the learning paths.

Purpose

Code Features provide:

  • Practical Examples: Working code that demonstrates real-world usage

  • Reusable Snippets: Copy-paste ready code for common tasks

  • Best Practices: Implementation patterns that follow BSV conventions

  • Modular Components: Code that can be combined for complex solutions

Organization

Features are organized by functionality and use case. Each feature includes:

  • Complete, runnable code examples

  • Explanation of what the code does

  • Prerequisites and dependencies

  • Common variations and extensions

  • Links to related SDK components

How to Use

Each code feature directory contains:

  1. README.md - Feature overview and explanation

  2. example.ts - Complete TypeScript example

  3. variations.md - Alternative approaches (if applicable)

In Learning Paths

Features are referenced in learning modules:

See [Transaction Creation](../../code-features/transaction-creation/README.md) for a complete example.

As Templates

Copy the example code and adapt to your needs:

// From code-features/transaction-creation/example.ts
import { Transaction } from '@bsv/sdk'
// ... rest of the code

Code Style

All examples follow these conventions:

  • TypeScript: Fully typed for clarity

  • Async/Await: Modern async patterns

  • Error Handling: Proper try/catch blocks

  • Comments: Explain key concepts

  • Imports: Show all required dependencies

Testing Examples

Most features include test cases showing expected behavior:

// example.test.ts
describe('Transaction Creation', () => {
  it('should create a valid transaction', () => {
    // test code
  })
})

Dependencies

Code features assume you have installed:

{
  "@bsv/sdk": "^1.0.0"
}

Additional dependencies are noted in each feature's README.
