@elaraai/e3-types

Shared type definitions for e3 (East Execution Engine).

Installation

npm install @elaraai/e3-types

Types

  • Repository - Repository configuration and paths
  • Package - Package manifest and metadata
  • Dataset - Dataset schemas and paths
  • Task - Task definition and configuration
  • Dataflow - Dataflow graph and execution state
    • TaskStateType - Individual task execution state
    • DataflowGraphType - Task dependency graph
    • ExecutionEventType - Execution progress events
    • DataflowExecutionStateType - Full execution state
  • Runner - Runner configuration
  • Workspace bundle - WorkspaceBundleType: a workspace as it is, in one stream — its head (WorkspaceBundleHeadType: package, dataset refs, executions), then its objects, each whole or in pieces

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
    • east-py-cli: CLI for running East IR programs in Python
    • east-py-datascience (PyPI) + @elaraai/east-py-datascience (npm): Optimization (MADS, Optuna, ALNS, GoogleOR), ML (XGBoost, LightGBM, NGBoost, PyTorch, Lightning, GP), Bayesian inference (PyMC), explainability (SHAP), conformal prediction (MAPIE)

  • East UI: Typed UI component definitions and React renderer, plus VS Code preview.

  • e3 — East Execution Engine: Durable execution engine for running East pipelines at scale. Git-like content-addressable storage, automatic memoization, reactive dataflow, real-time monitoring.

关于 @elaraai/e3-types 的常见问题

@elaraai/e3-types 是什么？

Shared type definitions for e3 (East Execution Engine)

如何安装 @elaraai/e3-types？

在项目目录运行 npm install @elaraai/e3-types，或使用 pnpm add / yarn add / bun add。它还需要宿主项目提供 peer 依赖：@elaraai/east（1.0.107）。npm 7 及以上与 pnpm 8 及以上默认会自动安装必需的 peer 依赖，Yarn 需要手动安装。

@elaraai/e3-types 支持 TypeScript 吗？

支持。包内自带 TypeScript 类型声明（package.json 声明了 types 入口），安装后即可获得类型提示，无需再安装 @types 包。

@elaraai/e3-types 支持 ESM 还是 CommonJS？

以 ES Module 形式发布，推荐使用 import 引入。在 CommonJS 项目中，Node.js 20.19+ / 22.12+ 可以直接 require() 不含顶层 await 的 ES Module，更早的版本需要改用动态 import()。

@elaraai/e3-types 可以商用吗？

@elaraai/e3-types 使用 AGPL-3.0-or-later 许可。最严格的 Copyleft：除分发外，通过网络向用户提供基于它的服务也需要开源对应源码。闭源 SaaS 使用前务必评估。以上为概括，不构成法律意见，请以许可原文为准。

@elaraai/e3-types 的下载量有多少？

根据 npm 官方下载统计，@elaraai/e3-types 在 2026/10/13 – 2026/11/11 这 30 天内被下载 7,949 次，日均约 265 次。下载量会把 CI 构建、镜像同步和作为其他包依赖的安装一并计入，适合横向比较热度，不能直接等同于使用人数。

@elaraai/e3-types 还在维护吗？

最新版本 1.0.107 发布于 2026/11/13（今天）；至今共发布 165 个版本，其中过去 12 个月发布了 165 个；首次发布于 2025/12/12。发布频率只是参考信号：功能稳定的工具可能很少需要更新，建议结合源码仓库的 issue 和提交记录判断。
