Primary LanguagePerl

Name

lua-resty-core - New FFI-based Lua API for the ngx_lua module

Table of Contents

Status

This library is still under early development and is still incomplete.

Synopsis

    # nginx.conf

    http {
        lua_package_path "/path/to/lua-resty-core/lib/?.lua;;";

        init_by_lua '
            require "resty.core"
        ';

        ...
    }

Description

This pure Lua library reimplements part of the ngx_lua's Nginx API for Lua with LuaJIT FFI and installs the new FFI-based Lua API into the ngx.* and ndk.* namespaces used by the ngx_lua module.

The FFI-based Lua API can work with LuaJIT's JIT compiler. ngx_lua's default API is based on the standard Lua C API, which will never be JIT compiled and the user Lua code is always interpreted (slowly).

Caveat

If the user Lua code is not JIT compiled, then use of this library may lead to performance drop in interpreted mode. You will only observe speedup when you get a good part of your user Lua code JIT compiled.
