# @push.rocks/smarthash
simplified access to node hash functions
# 🔐 @push.rocks/smarthash
## Install
To install `@push.rocks/smarthash`, use the following command with npm:
> **Cross-environment hashing made simple** 🚀
> SHA256 and MD5 hash functions that work seamlessly in both Node.js and browsers, with zero configuration.
[![npm version](https://img.shields.io/npm/v/@push.rocks/smarthash.svg)](https://www.npmjs.com/package/@push.rocks/smarthash)
[![TypeScript](https://img.shields.io/badge/TypeScript-Ready-blue.svg)](https://www.typescriptlang.org/)
[![Cross Platform](https://img.shields.io/badge/Platform-Node.js%20%7C%20Browser-brightgreen.svg)](#)
## ✨ Why SmartHash?
- 🌐 **Universal**: Works in Node.js AND browsers without polyfills
-**Smart Fallbacks**: Automatically handles Web Crypto API limitations (like non-HTTPS environments)
- 🔧 **TypeScript First**: Full type safety and IntelliSense support
- 📦 **Dual Entry Points**: Optimized builds for both environments
- 🎯 **Simple API**: Consistent interface across all platforms
## 🚀 Quick Start
```bash
npm install @push.rocks/smarthash --save
pnpm install @push.rocks/smarthash
```
This will add `@push.rocks/smarthash` to your project's dependencies.
## 📖 API Reference
## Usage
The `@push.rocks/smarthash` library provides a simplified interface to Node.js hash functions, including utilities for hashing strings, files, and streams with popular algorithms like SHA-256 and MD5. Below are detailed examples to demonstrate the capabilities and usage of this library using ESM syntax and TypeScript.
### 🔤 String Hashing
### Hashing Strings
#### SHA-256
```typescript
import { sha256FromString, sha256FromStringSync } from '@push.rocks/smarthash';
// Asynchronously hash a string
const asyncHash = async () => {
const hash = await sha256FromString('Hello, world!');
console.log(hash); // Output the hashed string
};
asyncHash();
// Async (works everywhere)
const hash = await sha256FromString('Hello, world!');
console.log(hash); // 📄 64-character hex string
// Synchronously hash a string
const syncHash = sha256FromStringSync('Hello, world!');
console.log(syncHash); // Output the hashed string
// Sync (Node.js only)
const hashSync = sha256FromStringSync('Hello, world!');
console.log(hashSync); // ⚡ Instant result
```
#### MD5
### 🗂️ File & Stream Hashing (Node.js Only)
```typescript
import { sha256FromFile, sha256FromStream } from '@push.rocks/smarthash';
import fs from 'fs';
// Hash files directly
const fileHash = await sha256FromFile('./myfile.txt');
console.log(fileHash); // 📁 File's SHA256 hash
// Hash streams (perfect for large files)
const stream = fs.createReadStream('./largefile.zip');
const streamHash = await sha256FromStream(stream);
console.log(streamHash); // 🌊 Stream's SHA256 hash
```
### 🧱 Buffer Hashing
```typescript
import { sha256FromBuffer } from '@push.rocks/smarthash';
// Works with both Buffer (Node.js) and Uint8Array (Browser)
const encoder = new TextEncoder();
const buffer = encoder.encode('Hello, world!');
const bufferHash = await sha256FromBuffer(buffer);
console.log(bufferHash); // 🔢 Buffer's SHA256 hash
```
### 🎯 Object Hashing
```typescript
import { sha256FromObject } from '@push.rocks/smarthash';
// Consistent hashing for JavaScript objects
const myObject = {
userId: 12345,
role: 'admin',
timestamp: Date.now()
};
const objectHash = await sha256FromObject(myObject);
console.log(objectHash); // 🎯 Deterministic object hash
```
> **🔥 Pro Tip**: Object property order doesn't matter! `{a: 1, b: 2}` and `{b: 2, a: 1}` produce the same hash.
### 🛡️ MD5 Hashing (Node.js Only)
```typescript
import { md5FromString } from '@push.rocks/smarthash';
// Asynchronously hash a string with MD5
const md5Hash = async () => {
const hash = await md5FromString('Hello, world!');
console.log(hash); // Output the MD5 hash
};
md5Hash();
// Legacy MD5 support (use SHA256 for new projects!)
const md5Hash = await md5FromString('Hello, world!');
console.log(md5Hash); // 🔐 32-character MD5 hash
```
### Hashing Files
To hash a file, you can use the `sha256FromFile` function. It reads the file specified by the path and calculates the SHA-256 hash.
```typescript
import { sha256FromFile } from '@push.rocks/smarthash';
## 🌍 Environment Compatibility
// Asynchronously hash a file
const hashFile = async () => {
const fileHash = await sha256FromFile('./path/to/your/file.txt');
console.log(fileHash); // Output the file's hash
};
hashFile();
```
| Function | Node.js | Browser | Notes |
|----------|---------|---------|-------|
| `sha256FromString` | ✅ | ✅ | Universal support |
| `sha256FromStringSync` | ✅ | ❌ | Sync not possible in browsers |
| `sha256FromBuffer` | ✅ | ✅ | Handles Buffer/Uint8Array |
| `sha256FromFile` | ✅ | ❌ | File system access required |
| `sha256FromStream` | ✅ | ❌ | Node.js streams only |
| `sha256FromObject` | ✅ | ✅ | Uses JSON serialization |
| `md5FromString` | ✅ | ❌ | Not supported by Web Crypto API |
### Hashing Streams
`@push.rocks/smarthash` also allows for hashing of streams, which is particularly useful for large files or data streams.
```typescript
import { sha256FromStream } from '@push.rocks/smarthash';
import fs from 'fs';
## 🔧 Advanced Usage
// Create a read stream from a file
const readStream = fs.createReadStream('./path/to/your/largeFile.txt');
### Error Handling
// Asynchronously hash the stream
const hashStream = async () => {
const streamHash = await sha256FromStream(readStream);
console.log(streamHash); // Output the hash of the stream's content
};
hashStream();
```
### Advanced Usage
#### Hashing Objects
For hashing JavaScript objects, you can serialize them and hash the resulting string. This is useful for creating hashes from complex data structures.
```typescript
import { sha265FromObject } from '@push.rocks/smarthash';
// Hash a JavaScript object
const hashObject = async () => {
const object = { hello: 'world', number: 42 };
const objectHash = await sha265FromObject(object);
console.log(objectHash); // Output the hash of the object
};
hashObject();
```
#### Error Handling
All asynchronous functions return promises, so you can use `.catch()` for error handling or try-catch blocks within async functions.
```typescript
import { sha256FromString } from '@push.rocks/smarthash';
// Using .catch() for promises
sha256FromString('test')
.then(hash => console.log(hash))
.catch(error => console.error(error));
// Using try-catch with async functions
const getHash = async () => {
try {
const hash = await sha256FromString('test');
console.log(hash);
} catch (error) {
console.error(error);
}
};
getHash();
try {
const hash = await sha256FromString('sensitive data');
console.log(`✅ Hash computed: ${hash}`);
} catch (error) {
console.error('❌ Hashing failed:', error);
}
```
### Best Practices
- Utilize asynchronous functions for hashing large files or streams to avoid blocking the main thread.
- For hashing sensitive information, ensure to follow security best practices, including using up-to-date algorithms and managing secrets properly.
### Browser-Specific Features
By leveraging `@push.rocks/smarthash`, developers can easily integrate hashing functionalities into their Node.js applications, benefiting from its simplified API and TypeScript support for better development experience.
In browsers, SmartHash automatically:
- 🔒 Uses Web Crypto API when available (HTTPS contexts)
- 🔄 Falls back to pure JavaScript implementation in non-HTTPS environments
- ⚠️ Warns when trying to use Node.js-only functions
### Import Strategies
```typescript
// Main entry point (Node.js optimized)
import { sha256FromString } from '@push.rocks/smarthash';
// Browser-specific entry point (smaller bundle)
import { sha256FromString } from '@push.rocks/smarthash/web';
```
## 🛠️ Development
```bash
# Run tests (both Node.js and browser)
pnpm test
# Build the project
pnpm build
# Generate documentation
pnpm buildDocs
```
## 🔐 Security Notes
-**SHA256**: Cryptographically secure, recommended for all use cases
- ⚠️ **MD5**: Legacy support only, not recommended for security-critical applications
- 🌍 **Cross-Environment**: Produces identical hashes across Node.js and browsers
- 🔒 **Web Crypto**: Uses native browser APIs when available for maximum performance
