SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates the integration of lightweight serverless functions into APISIX request processing, enabling quick prototyping and targeted behavior without building full plugins.

Core Features & Use Cases

  • Inline Lua function definitions for pre-function and post-function phases
  • Phase configuration with phase and functions arrays, including compile-time validation
  • Clear execution order and function signatures to ensure predictable behavior across routes and globals
  • Real-world use cases: authentication guards, request/response modification, and dynamic routing decisions

Quick Start

Use the a6 CLI to create a route that applies serverless-pre-function or serverless-post-function with a list of Lua functions.

Frequently Asked Questions about a6-plugin-serverless

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run inline Lua functions during APISIX request processing?▼

You can run inline Lua functions in APISIX by configuring the serverless-pre-function or serverless-post-function plugins. This enables route-level pre-processing and post-processing of API traffic without building full plugins.

What is the best way to add a lightweight authentication guard to an APISIX route?▼

Using APISIX serverless plugins is the best way to add lightweight authentication guards. You define inline Lua functions within the serverless-pre-function plugin to intercept and validate requests during the pre-processing phase.

Can I use the a6 CLI to configure serverless plugins for APISIX?▼

Yes, you can use the a6 CLI to create routes and configure APISIX serverless plugins. It helps specify required frontmatter metadata, plugin phases, and function strings while ensuring compile-time validation at load time.

How does APISIX execute multiple serverless functions in a specific order?▼

APISIX executes serverless functions based on the functions array you define, ensuring a clear execution order. The plugin validates function signatures and compiles the Lua code at load time for predictable behavior across routes.

Do I need to build a full APISIX plugin to modify API responses dynamically?▼

No, you do not need to build a full plugin to modify API responses. You can use the serverless-post-function plugin to run inline Lua functions during the post-processing phase for quick prototyping and targeted behavior.
