### ZSTDDecoder Initialization and Decoding

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

This snippet shows how to initialize the ZSTDDecoder and use it to decompress data. It requires the compressed data and optionally the uncompressed size.

```APIDOC
## ZSTDDecoder API

### Description
Provides methods to initialize and use a WebAssembly-based Zstandard decoder.

### Initialization
```javascript
import { ZSTDDecoder } from 'zstddec';

const decoder = new ZSTDDecoder();
await decoder.init();
```

### Decoding
```javascript
// Assuming 'compressedArray' is your compressed data (e.g., Uint8Array)
// and 'uncompressedSize' is the expected size of the decompressed data (optional but recommended)
const decompressedArray = decoder.decode( compressedArray, uncompressedSize );
```

### Limitations
- The `decode()` method may fail if `uncompressedSize` is not provided. This is a known issue potentially related to WASM bindings.
```

--------------------------------

### Initialize and Decode with ZSTDDecoder

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

Initialize the ZSTDDecoder and decode a compressed array. Ensure uncompressedSize is provided to avoid potential errors.

```javascript
import { ZSTDDecoder } from 'zstddec';

const decoder = new ZSTDDecoder();

await decoder.init();

const decompressedArray = decoder.decode( compressedArray, uncompressedSize );
```

--------------------------------

### Build zstd

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

Build the zstd library from source.

```shell
# build zstd
make
cd build/single_file_libs
./create_single_file_decoder.sh
```

--------------------------------

### Run Tests

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

Execute project tests using yarn.

```shell
yarn test
```

--------------------------------

### Compile zstddec.wasm

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

Compile the zstddeclib.c file into a WebAssembly module for decoding.

```shell
# build wasm
emcc zstddeclib.c -s EXPORTED_FUNCTIONS="['_ZSTD_decompress', '_ZSTD_findDecompressedSize', '_ZSTD_isError', '_malloc', '_free']" -Wl,--no-entry -s WASM=1 -Oz -g0 -flto -s ALLOW_MEMORY_GROWTH=1 -s FILESYSTEM=0 -s STANDALONE_WASM=1 -DNDEBUG=1 -s PURE_WASI=0 -o zstddec.wasm
```

--------------------------------

### Compile zstddec-stream.wasm

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

Compile the zstddeclib.c file into a WebAssembly module for streaming decoding.

```shell
# build streaming wasm
emcc zstddeclib.c -s EXPORTED_FUNCTIONS="['_ZSTD_decompress', '_ZSTD_findDecompressedSize', '_ZSTD_createDCtx', '_ZSTD_decompressStream', '_ZSTD_freeDCtx', '_ZSTD_DStreamInSize', '_ZSTD_DStreamOutSize', '_malloc', '_free']" -Wl,--no-entry -s WASM=1 -Oz -g0 -flto -s ALLOW_MEMORY_GROWTH=1 -s FILESYSTEM=0 -s STANDALONE_WASM=1 -DNDEBUG=1 -s PURE_WASI=0 -o zstddec-stream.wasm
```

--------------------------------

### Encode WASM to Base64

Source: https://github.com/donmccurdy/zstddec-wasm/blob/main/README.md

Encode the compiled WebAssembly files into base64 format for embedding.

```shell
# encode WASM to base64
base64 -i zstddec.wasm > zstddec.txt
base64 -i zstddec-stream.wasm > zstddec-stream.txt
```
