Living Spec Standalone (Web Server Binary)

This app runs as a single Rust web server binary that serves the Vite/React frontend and exposes APIs. The frontend lives in the frontend/ directory.

You can also run the frontend and backend separately in development (Vite dev server + Rust API).

Running it in development

# Build the frontend
cd frontend
pnpm install 
pnpm dev

# Run the server (serves embedded frontend/dist/)
cargo run

Production

# Build the release binary (also builds the frontend via build.rs)
cargo build --release

# Run the server (serves embedded frontend/dist/)
./target/release/story-kit-server

Cross-Platform Distribution

Story Kit ships as a single self-contained binary with the React frontend embedded via rust-embed. No Rust toolchain, Node.js, or extra libraries are required on the target machine.

macOS

# Native build – no extra tools required beyond Rust + pnpm
make build-macos
# Output: target/release/story-kit-server

# Verify only system frameworks are linked (Security.framework, libSystem.B.dylib, etc.)
otool -L target/release/story-kit-server

Linux (static x86_64, zero dynamic deps)

The Linux build uses the x86_64-unknown-linux-musl target to produce a fully static binary.

Prerequisites:

# Install cross – a Rust cross-compilation tool backed by Docker
cargo install cross

# Ensure Docker Desktop (or Docker Engine) is running

Build:

make build-linux
# Output: target/x86_64-unknown-linux-musl/release/story-kit-server

# Verify the binary is statically linked
file target/x86_64-unknown-linux-musl/release/story-kit-server
# Expected: ELF 64-bit LSB executable, x86-64, statically linked

ldd target/x86_64-unknown-linux-musl/release/story-kit-server
# Expected: not a dynamic executable

Running on any Linux x86_64 machine:

# No Rust, Node, glibc, or any other library needed – just copy and run
./story-kit-server

Testing

Frontend Tests

The frontend uses Vitest for unit tests and Playwright for end-to-end tests.

cd frontend

# Run unit tests
pnpm test

# Run end-to-end tests
pnpm test:e2e

Backend Tests

This project uses nextest for running tests and cargo-llvm-cov for code coverage.

Install Tools

cargo install cargo-nextest cargo-llvm-cov

Run Tests

# Run all tests
cargo nextest run

# Run specific module
cargo nextest run search_files

# Run with verbose output
cargo nextest run --no-capture

Generate Coverage

# HTML report (opens in browser)
cargo llvm-cov nextest --html --open

# Terminal output
cargo llvm-cov nextest

# LCOV format (for CI)
cargo llvm-cov nextest --lcov --output-path lcov.info

# Clean coverage data
cargo llvm-cov clean

Configuration

• Nextest config: .config/nextest.toml
• Coverage output: target/llvm-cov/html/index.html
