React-native-fast-encoder

Key Features:

• Based on: react-native-fast-openpgp for initial groundwork.
• Leverages JSI: Utilizes JSI (JavaScript Interface) to perform text encoding functions on the native side (Golang)
• Encoding: Only supports UTF-8 for now.

Usage:

npm i react-native-fast-encoder
const TextEncoder = require('react-native-fast-encoder');
window.TextEncoder = TextEncoder;
window.TextDecoder = TextEncoder;

3. Now, you can use the standard TextEncoder and TextDecoder APIs for your text encoding/decoding operations, and the library will automatically utilize the efficient native implementations.

Benchmark Results (React Native with Hermes engine):

Task	text-encoding (ms)	react-native-fast-encoder (ms)	Performance Improvement
Encode 100kb string	220	3	73x faster
Encode 100 * 100kb strings	18,000	100	180x faster
Encode 10k small strings	210	50	4.2x faster
Decode 100kb string	180	1	180x faster
Decode 100 * 100kb strings	17,000	25	680x faster
Decode 10k small strings	160	45	3.5x faster

Performance Expectations:

You can expect significant performance improvements (4x to 100x) compared to the 'text-encoding' library, especially when dealing with large strings. This gain results from utilizing the more efficient native implementations through JSI.
