This repository provides a transparent proxy package for OpenWrt using Mihomo (a clash-compatible rule-based proxy core) as the backend. It is a full LuCI application that allows users to configure proxy modes (redirect, TPROXY, TUN), manage subscriptions, define access control rules, and monitor logs through a web interface. The system is designed for OpenWrt ≥24.10 with firewall4 (nftables) and kernel ≥5.13. The architecture consists of three OpenWrt packages: `nikki` (main service and scripts), `mihomo-meta` (stable core), and `mihomo-alpha` (alpha variant). The service is managed via procd init script (`nikki.init`), which handles starting/stopping Mihomo, setting up routing rules and nftables tables, and scheduling tasks. Configuration is stored in UCI (OpenWrt's standard configuration system) and processed through a pipeline: UCI options → `mixin.uc` (ucode script) generates a JSON overlay → `yq` merges it with a base profile → final Mihomo config. Traffic interception rules are generated dynamically from a utpl template (`hijack.ut`) that produces nftables rulesets. Key entry points include the LuCI views (`app.js`, `profile.js`, `mixin.js`, `proxy.js`, `editor.js`, `log.js`) for web-based management, the init script for service lifecycle, and shell scripts for installation/upgrade. External dependencies are Mihomo core, `yq` for YAML processing, and standard OpenWrt tools (procd, nftables, ucode). The repository also includes a large hardcoded nftables set of Chinese IP prefixes (`geoip_cn.nft`) for bypassing mainland China traffic.
