Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

East Node CLI

Command-line interface for running East IR programs with Node.js

License Node Version

East Node CLI provides a command-line interface for executing compiled East IR programs using Node.js platform implementations.

Installation

# Install the CLI
npm install -g @elaraai/east-node-cli

# Install platform packages (required)
npm install @elaraai/east-node-std
npm install @elaraai/east-node-io  # if using I/O functions

Usage

Running Programs

# Run with standard platform
east-node run ./program.beast2 -p @elaraai/east-node-std

# Run with multiple platforms
east-node run ./db-query.beast2 \
    -p @elaraai/east-node-std \
    -p @elaraai/east-node-io

# Run with input files
east-node run ./transform.beast2 \
    -p @elaraai/east-node-std \
    -i input.json \
    -i config.east

# Run with output file
east-node run ./process.beast2 \
    -p @elaraai/east-node-std \
    -i input.beast2 \
    -o result.json

# Verbose mode
east-node run ./program.beast2 -p @elaraai/east-node-std -v

CLI Reference

east-node run

Execute an East IR program.

east-node run <ir_file> [options]

Arguments:
  ir_file                    Path to IR file (.beast2, .beast, .east, or .json)

Options:
  -p, --package <package>    Platform package to load (can be repeated)
  -i, --input <file>         Input data file (can be repeated)
  -o, --output <file>        Output file path for result
  -v, --verbose              Enable verbose output
  -h, --help                 Display help

east-node version

Show version information.

east-node version [options]

Options:
  -p, --package <package>    Platform package to check (can be repeated)

Supported File Formats

| Extension | Format | |-----------|--------| | .beast2, .beast | Binary East format | | .east | Text East format | | .json | JSON format |

Platform Packages

Platform packages provide the runtime implementations for East platform functions:

Creating Platform Packages

Any npm package can provide platform functions by following this convention:

  1. Export a ./platform subpath that default-exports PlatformFunction[]
  2. Export ./package.json for version discovery

See the design document for details.

Claude Code plugin

The East ecosystem also ships a Claude Code plugin — East language skills, example search, and preemptive diagnostics for East code — installed separately from the elaraai marketplace:

# Inside Claude Code
/plugin marketplace add elaraai/east-workspace
/plugin install east@elaraai
# From a terminal
claude plugin marketplace add elaraai/east-workspace
claude plugin install east@elaraai

Ecosystem

  • East: Statically typed, expression-based language with serializable IR. Run portable logic across TypeScript, Python, C, and other runtimes.

    • @elaraai/east: Core language SDK with type system, expressions, and reference JS compiler

  • East Node: Node.js platform functions for I/O, databases, and system operations.

  • East C: C11 native runtime for executing East IR. Distributed via npm (launcher + per-platform optional dependencies) and as tarballs on each GitHub Release.

    • @elaraai/east-c-cli: npm launcher — installs the matching native binary as an optional dependency
    • east-c: Core runtime — type system, IR interpreter, builtins, serialization (Beast2, JSON, CSV, East text)
    • east-c-std: Console, FileSystem, Fetch, Crypto, Time, Path, Random
    • east-c-cli: CLI for running East IR programs natively

  • East Python: Python runtime, standard platform, I/O, and data-science platform functions. Published to PyPI.

    • east-py: Core Python runtime — type system, IR compiler, 212+ builtins, Cython-accelerated hot paths
    • east-py-std: Console, FileSystem, Fetch, Crypto, Time, Path, Random
    • east-py-io: SQLite, PostgreSQL, MySQL, MongoDB, Redis, S3, FTP, SFTP, XLSX, XML, compression
