This is a large, scaffolded e-commerce backend system built with the go-zero microservice framework. It implements a full suite of admin and frontend APIs for managing products, orders, members, coupons, content, and system settings. The architecture is microservices-based with separate RPC services for each domain (sys, cms, oms, pms, sms, ums) plus search, consumer, and job services. The codebase is heavily generated using goctl and gorm.io/gen, resulting in a high volume of boilerplate CRUD logic files—many of which are still stubs containing only 'todo: add your logic here' comments. While the system demonstrates a consistent pattern for service decomposition and provides reusable utility packages (pkg/errorx, pkg/time_util, pkg/mq), the majority of business logic is incomplete, and there are signs of technical drift such as duplicate JWT library usage, mixed ORM approaches, and hardcoded configuration values. The project is actively maintained but still in a work-in-progress state, with the README warning of significant backend changes and incomplete frontend adaptation.
This is a Go CLI tool that scrapes certification exam questions and answers from the examtopics.com website, which is otherwise paywalled or requires manual browsing. The tool accepts a provider (e.g., google, cisco) and a search string to filter exams, then fetches all discussion pages, extracts question data (text, choices, community-voted answer, timestamp, comments), and outputs the results in Markdown, JSON, HTML, PDF, or plain text. It includes optional caching via a GitHub repository of pre-scraped data, rate limiting, retry logic, and concurrent request concurrency. The architecture is a single-binary monolith with internal packages for fetching, scraping, and file output. The code is functional but unremarkable—standard Go patterns with some concurrency, though the global counter and finalizer usage are minor anti-patterns.
Pangee Cluster is a graphical tool for offline Kubernetes cluster lifecycle management, including installation, upgrade, backup, node operations, and SSH access. The backend is a Go REST API (Gin) that orchestrates Ansible playbooks from versioned resource packages. The frontend is a Vue 3 single-page application (with some legacy Vue 2 patterns) that provides a comprehensive UI for cluster planning, operation execution, real-time log tailing, and SSH terminal. The tool is primarily designed for air-gapped environments where clusters are provisioned from pre-packaged resource bundles containing Kubernetes binaries, container runtimes, and Ansible roles. Despite its functional breadth, the codebase shows signs of technical debt: mixed Vue API styles, heavy mixins, no test suite, and tight coupling to a custom-patched Ansible version. The resource package abstraction and generic form editing components are notable for reusability, but overall the architecture is typical of a production tool that has evolved organically rather than being designed for clean reuse.
This repository is a personal monorepo of Go CLI tools built by nikivdev, primarily revolving around the 'fgo' command (aliased as 'fe'), which provides a fast, interactive command palette for various developer workflows. The toolset includes AI-powered commit message generation via OpenAI, GitHub PR cloning and checkout, port killing, symbolic link management, scratch directory creation, private forking of repos, and integration with macOS-specific tools like osascript and pbpaste. Additional standalone CLIs include 'spec' for converting Markdown specs into Codex execution prompts with optional publishing to unhash.sh, 'ghx' for PR diff retrieval, 'tscp' for Tailscale-based file copy, and 'unite' for unified fuzzy search across multiple CLIs. The repository also contains an experimental Dockerfile layer analyzer library with tests. The codebase is actively maintained but heavily optimized for the author's personal macOS environment, with hardcoded paths and macOS-specific dependencies, making it less portable without modification. The architecture is a flat collection of independent CLI tools sharing common patterns like the go-snap CLI framework and go-fuzzyfinder for interactive selection.
Mantrae is a self-hosted web UI for managing Traefik dynamic configuration, including routers, services, middlewares, entry points, and server transports. The backend is written in Go using ConnectRPC/protobuf for the API layer, sqlc-generated code for SQLite persistence, and a Svelte frontend for the user interface. It provides CRUD and operational workflows for Traefik resources, DNS providers, users, agents, backups, and profiles. The README explicitly states that development has moved to Tether, making this project superseded. The codebase is a monorepo with large amounts of generated protobuf and sqlc code committed alongside hand-written service logic. It uses modern tooling such as buf, sqlc, goreleaser, and ko, but has no visible tests, some incomplete documentation, and a minimal OpenAPI spec. The UI includes generic data table components with sorting, filtering, pagination, and bulk actions. Overall, it is a functional but unremarkable application with moderate maintainability and limited reuse potential outside its own architecture.
This repository provides gocode, an autocompletion daemon for the Go programming language. It operates as a client-server system where editors send source code and cursor position to a caching daemon, which returns context-sensitive completion candidates based on an internal type inference engine and package cache. The codebase includes robust parsers for compiled Go package archives (text, binary, indexed binary formats), a sophisticated token-based expression extractor for cursor context, and a config management system. However, the project is explicitly deprecated in favor of gopls, has not seen recent maintenance, and relies on outdated Go versions and build constraints. Its value now is primarily historical or as a reference for implementing basic Go completion in editors.
This repository is a collection of code samples written in a Go-like DSL (not standard Go) that demonstrate how to use various Google Cloud Platform (GCP) services. The samples are organized by service (e.g., BigQuery, Spanner, Pub/Sub, Compute, Storage, Cloud Functions, Cloud Run, DLP, GenAI, etc.) and are primarily intended for inclusion in official GCP documentation, as evidenced by the pervasive `[START ...]` / `[END ...]` region tags. The codebase is not a production application or library; it is a reference resource for developers learning GCP APIs. The architecture is modular, with each sample typically consisting of a single function performing one API operation. Quickstart `main.go` files provide runnable entry points, and integration tests use an internal test utility framework (`internal/testutil`, `internal/cloudrunci`) that is tightly coupled to the repository's CI infrastructure. The code relies on a non-standard Go syntax (e.g., `import ( ... )`, `func`, `error` return type, `defer`, `io.Writer`) that does not compile with standard Go toolchains, significantly limiting reusability outside of this documentation context. The samples are actively maintained but exhibit high technical drift due to the custom DSL and version-specific API references.
This is a lightweight SMTP server written in Go, designed to receive large volumes of email, parse MIME content, and store messages in MongoDB. It includes a web interface for viewing messages, managing greylisting, and real-time notifications via WebSockets (using the embedded Incus library). The server implements core SMTP commands (HELO/EHLO, MAIL, RCPT, DATA, AUTH, STARTTLS, XCLIENT) and supports TLS, greylisting, and spam filtering via regex. The architecture is monolithic: a single binary runs both the SMTP listener and an HTTP server for the web UI. The codebase is functional but shows signs of age: it uses deprecated dependencies (gopkg.in/mgo.v2, github.com/robfig/config, github.com/gosexy/redis), lacks a go.mod file, and has no automated tests. The SMTP protocol handling is reasonably robust, and the MIME parsing is non-trivial, but the overall project would benefit from modernization and testing.
This repository provides a command-line tool for decrypting and unpacking WeChat mini-program package files (.wxapkg). The tool takes a .wxapkg file as input, extracts the wxid from the file path, decrypts the file if necessary using a hardcoded IV and salt with PBKDF2-derived AES-CBC keys, and then unpacks the decrypted file into a directory containing the original mini-program source files. The architecture is a simple monolithic Go application with two internal packages: `decrypter` for handling the decryption process and `unpacker` for parsing the wxapkg binary format and extracting files. The main function in `main.go` orchestrates the flow: argument parsing, decryption (if needed), and unpacking. The decrypter package demonstrates competent use of Go's crypto libraries for AES-CBC decryption and PBKDF2 key derivation, though it is tightly coupled to the WeChat-specific file format (fixed IV, salt, and XOR step). The unpacker package provides a clean, self-contained implementation for reading the wxapkg index structure and extracting embedded files, relying only on the Go standard library. However, the repository is marked as archived by the maintainer due to the inability to keep up with WeChat's frequent updates, indicating that the tool may not work with newer versions of the wxapkg format.
This repository is a community-driven collection of programming exercise solutions, organized as a numbered roadmap (00 to 50) covering fundamental to intermediate topics. Each exercise is solved in multiple programming languages (Python, JavaScript, Java, C++, Go, Kotlin, etc.) by different contributors. The code consists of standalone scripts that demonstrate language features such as recursion, data structures, exception handling, async programming, regular expressions, design patterns (Singleton, Decorator), and SOLID principles. The repository is not a cohesive application or library; it is an educational resource for learning and practicing programming concepts across languages. The quality of solutions varies widely, with some files containing errors or being incomplete. The project relies on community contributions and lacks centralized testing or dependency management.
This repository is a documentation-only project that describes a conventional directory layout for Go applications. It contains no executable source code, no tests, no CI/CD pipelines, and no functional software of any kind. The entire repository consists of README files (translated into ~20 languages), a placeholder go.mod with a dummy module path, a nearly empty Makefile, and .keep files in empty directories. The go.mod references go 1.19 and contains no dependencies. There are no Go source files anywhere in the repository. The project serves purely as a reference template showing recommended directory structures (cmd/, internal/, pkg/, api/, web/, configs/, scripts/, build/, deployments/, test/, docs/, tools/, examples/, third_party/, githooks/, assets/, website/, init/) for Go projects, with links to real-world examples that follow these conventions. The last commit was in April 2026 but there is essentially nothing to maintain — the content is static documentation that has remained unchanged in substance for years. The README itself acknowledges this is not an official Go team standard but a community-driven collection of common patterns.
