## Purpose

The purpose of this library is to implement LZ4 compression/decompression,
as documented at the official LZ4 repository:

https://github.com/lz4/lz4/blob/dev/doc/lz4_Block_format.md

The files in this directory are developed as a separate project at:

https://github.com/gorhill/lz4-wasm

## Files

### `lz4-block-codec-any.js`

The purpose is to instanciate a WebAssembly- or pure javascript-based
LZ4 block codec.

If the choosen implementation is not specified, there will be an attempt to
create a WebAssembly-based instance. If for whatever reason this fails, a
pure javascript-based instance will be created.

The script for either instance are dynamically loaded, such that no resources
are wasted by keeping in memory code which won't be used.

### `lz4-block-codec-wasm.js`

This contains the code to instanciate WebAssembly-based LZ4 block codec. Note
that the WebAssembly module is loaded using a `same-origin` fetch, hence
ensuring that no code outside the package is loaded.

### `lz4-block-codec-js.js`

This contains the code to instanciate pure javascript-based LZ4 block codec.

This is used as a fallback implementation should WebAssembly not be available
for whatever reason.

### `lz4-block-codec.wasm`

This is the WebAssembly module, loaded by `lz4-block-codec-wasm.js` using a
`same-origin` fetch.
