svgpack

Fast SVG optimizer for build pipelines, implemented in Rust.

This repository contains the first working version of svgpack as a Rust workspace with:

• CLI command entrypoint
• Core optimization pipeline orchestration
• Basic parser helpers
• MVP optimizer passes
• Sprite generation (symbol format)
• React component code generation
• Duplicate detection
• Basic SVG analysis reporting

Current status

Version target: v0.1.0 (MVP foundation).

Implemented:

• optimize flow (single file or directory)
• --in-place, --dry-run, --stats, and --format json
• sprite subcommand
• codegen subcommand (--framework react)
• dedup subcommand
• analyze subcommand

Build

Requirements:

• Rust stable toolchain
• Cargo

Commands:

cargo fmt
cargo check
cargo test

CLI usage

Run via cargo:

cargo run -p svgpack_cli -- <args>

Optimize:

cargo run -p svgpack_cli -- icons/ -o dist/icons/ --stats

Optimize in place:

cargo run -p svgpack_cli -- icons/ --in-place

Dry run:

cargo run -p svgpack_cli -- icons/ --dry-run --stats

JSON output:

cargo run -p svgpack_cli -- icons/ --format json

Sprite generation:

cargo run -p svgpack_cli -- sprite icons/ -o dist/sprite.svg

React codegen:

cargo run -p svgpack_cli -- codegen icons/ -o src/icons/ --framework react --index

Duplicate detection:

cargo run -p svgpack_cli -- dedup icons/

Analyze:

cargo run -p svgpack_cli -- analyze icons/

Config

You can pass a JSON config with --config:

cargo run -p svgpack_cli -- --config svgpack.config.json icons/ -o dist/icons/

Supported now:

• preset
• multipass
• max_passes
• passes map (enabled, precision, prefix)

Roadmap

• v0.2: stronger path/transforms optimization + better SVGO parity.
• v0.3: sprite improvements + React/Vue codegen hardening.
• v0.4: build-tool plugins (Vite/Rspack/Webpack) + watch mode.
• v1.0: stable API, regression corpus, performance benchmarks.

Notes

• This is a first version focused on architecture and working command flow.
• Path-data optimization is still minimal and should be expanded in the next iteration.
• Visual regression tests and SVGO compatibility mapping are planned next.
