Learn OpenResty (NGINX + Lua) - API7.ai

This post introduces OpenResty's directory structure and related tools, such as NGINX C Modules, test-nginx, lua-resty projects, and more.

Nginx provides the Master-Worker model and request execution phases. By reading this post, you can better grasp the basics of Nginx.

Lua is a lightweight and high-level programming language designed primarily for embedded use in applications. Getting started with Lua from here!

The lua-resty-core is a new FFI-based API for lua-nginx-module, which provides higher performance. Learn more from this post.

Explore Lua's unique data structure, the table, and its metatable functionalities, guiding you through efficient usage and best practices.

OpenResty is built with NGINX and LuaJIT, getting started from here to learn its basic concepts and how it works.

OpenResty is the enhanced NGINX with dynamic requests and responses, and this article explains the APIs for manipulating Request and Response in OpenResty, such as "ngx.req.set_method", "ngx.req.set_uri_args", "ngx.req.set_header", etc.

The cosocket is the basis of various lua-resty-* non-blocking libraries. This article introduces the basic concepts and common APIs of cosocket.

This article will introduce you to the use of OpenResty common APIs for time manipulation, regular expressions, and other common issues.

This article describes the features of the performance testing tool `wrk` and how to use it for efficient and accurate performance testing

This article introduces the optimization techniques to be followed in OpenResty: processing requests short, simple, and fast and avoiding intermediate data generation. It also shows the optimization techniques for string

This article describes how to debug in OpenResty using breakpoints and print logs, Binary Search Algorithm and Comment, dynamic debugging, flame graph, etc.

We can use active update cache, lua-resty-lock, lua-resty-shcache, and NGINX directives to resolve cache stampedes in NGINX, OpenResty.

Let's learn how to use the implementation of `limit-req`, `limit-count`, `limit-conn`, and `limit.traffic` in `lua-resty-limit-traffic` and conduct rate limiting with them.
