GOX Server

Official website

The compiler, development server, and command-line tools for GOX. Build web applications with Go handlers, HTML templates, Actions, WebSockets, and client components using React, Preact, Solid, Vue, or Svelte.

• GOX SDK — application APIs and server contracts.
• Demo — interactive examples and a demo store.
• RedisAdapter — optional shared sessions and communication between server instances.

Install with Go

With Go 1.26 or later:

go install github.com/gox-lang/server/cmd/gox@latest
gox version

Go installs the gox executable in GOBIN, or in $(go env GOPATH)/bin when GOBIN is unset. Ensure that directory is on your PATH. For the standard Go configuration, add this line to your shell profile:

export PATH="$(go env GOPATH)/bin:$PATH"

Use Linux, macOS, or WSL to run applications that require Go plugins. Native Windows supports the CLI and language server, but not Go plugins.

Build the CLI

GOX runs on Linux, macOS, and Windows. On Windows, gox ls provides native editor support; use WSL for application development and execution because Go plugins are not supported on native Windows.

Install Go matching the version required by go.mod, or a newer compatible version. Run the commands below from a checkout of this repository.

Linux and macOS

Build and install the executable in /usr/local/bin, so it is available from any project directory:

go build -trimpath -o ./build/gox ./cmd/gox
sudo install -m 755 ./build/gox /usr/local/bin/gox

If /usr/local/bin is not already in your PATH, add the following line to your shell configuration (~/.bashrc for Bash or ~/.zshrc for Zsh), then open a new terminal:

export PATH="/usr/local/bin:$PATH"

Verify the installation

From any directory:

gox version
gox --help

GOX provisions its managed Go, Node.js, and pnpm toolchains when needed; initial setup requires internet access. To update a locally built installation, rebuild from the updated checkout and repeat the install command above.

Visual Studio Code

GOX Tools is the official VS Code extension for GOX. It provides syntax highlighting, snippets, visibility hints, GOX Dark and GOX Light themes, and language features powered by the gox ls language server: completion, diagnostics, and navigation.

Install GOX Tools from Visual Studio Marketplace, or run this command with the VS Code CLI:

code --install-extension gox-lang.gox-tools

With GOX Tools 0.1.4 or newer, the extension automatically locates GOX or installs an official release for the extension host. No separate Go installation is required: gox ls prepares its managed Go toolchain. Existing installations and a custom gox.languageServer.path are respected.

New VS Code terminals receive the GOX executable directory in PATH. Managed installations receive stable GOX updates through the language server; running applications are not restarted. Use gox update for an explicit update.

VS Code 1.91 or newer is required. Windows supports the native language server; use VS Code connected to WSL for application development and execution.

Updates

Run gox update to check the official stable release immediately, verify its SHA-256 checksum, and install the new executable. Existing applications keep running their current version; project dependencies are not changed.

gox run checks in the background at most once every 24 hours and recommends gox update when a newer version is available. It never installs an update. The check is cached between processes, and network failures do not stop GOX.

gox ls can install updates for installations managed by GOX Tools when the extension enables update coordination. It notifies the extension to restart the language server after validating and installing the executable. External installations receive an update notice instead. Development builds do not participate in automatic stable-release updates.

Start a project

gox createproject my-app
cd my-app
gox run

To start with the complete demo:

gox createproject my-demo --demo
cd my-demo
gox run

gox createproject --demo uses demo as the project name. The destination must not already exist. GOX creates the normal scaffold, sets up React, Preact, Solid, Vue, and Svelte, then downloads the demo sources from gox-lang/demo.

Client components and dependencies

From an existing project:

gox client add react preact solid vue svelte
gox get github.com/gox-lang/redisadapter

RedisAdapter is optional and must be configured explicitly. GOX does not install it automatically. See its repository for Redis requirements and setup.

Use gox --help and gox <command> --help for available commands and options.

Development

go test ./...
go vet ./...
node --test internal/websocket/*.test.js internal/clientbuilder/*.test.mjs

Some integration tests require additional tools or services and skip when their prerequisites are unavailable. For SDK and cluster changes, also run the SDK's tests and RedisAdapter's integration suite with an isolated Redis instance. See AGENTS.md for the compatibility requirements.

Before a coordinated release, verify the adapter checkout uses the same published SDK version as this server:

GOX_REDIS_ADAPTER_DIR=../redisadapter go test ./internal/deps -run TestSDKVersionCompatibility

Both consumers currently require GOX SDK v1.1.1. Local SDK replacement directives must not be committed.

See RELEASING.md for repository setup and release order.
