# 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:**

```javascript
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.
