demo-functions

A minimal npm package that exports two functions for debugging demonstration in React Native applications.

Functions

• badFunction(): Always throws an error (perfect for debugging demonstration)
• goodFunction(): Always returns a good value

🐛 Debugging Support

This package is specifically configured with comprehensive source maps to enable full debugging capabilities in React Native applications:

• ✅ Source Maps: Generated for both JavaScript and TypeScript declaration files
• ✅ Step-Through Debugging: Set breakpoints and step into package functions
• ✅ Error Stack Traces: See original TypeScript line numbers in error messages
• ✅ React Native Compatible: Optimized configuration for React Native debugging

Debugging Setup

1. Install the package in your React Native app
2. Set breakpoints in your app code where you call the package functions
3. Start debugging - you can now step into the package source code!

📦 Installation

npm install demo-functions

💻 Usage

Individual Function Imports

import { badFunction, goodFunction } from "demo-functions";

// This will throw an error - perfect for debugging demonstration!
try {
  badFunction();
} catch (error) {
  console.log("Caught error:", error);
  // You can set breakpoints here and step into badFunction()
}

// This returns a good value
const result = goodFunction();
console.log(result); // "good function always returns good value"

Default Object Import

import demoFunctions from "demo-functions";

// Access functions through the default export
console.log(demoFunctions.badFunction());
console.log(demoFunctions.goodFunction());

TypeScript Support

import { badFunction, goodFunction } from "demo-functions";

// Full TypeScript support with proper type inference
const result: string = goodFunction();
