The project site and README emphasize microcontroller-class memory budgets, C99 portability, on-device compilation and execution, bytecode snapshots, and an embeddable C API. ### プロジェクトの歴史 The public GitHub repository dates to 2015. The project presented itself early as a JavaScript engine for devices with less than 64 KB of RAM and less than 200 KB of flash, targeting a niche that mainstream browser and server JavaScript engines did not fit. JerryScript reached a 1.0 GitHub release in 2016 and continued through the 2.x and 3.x release lines. Later release notes show the project expanding beyond its original ECMAScript 5.1 baseline, while still tracking footprint and conformance as central engineering constraints. ### 採用の歴史 JerryScript gained ecosystem legitimacy by becoming an OpenJS Foundation hosted project. The OpenJS project listing describes it as a fully featured JavaScript engine for IoT devices, and the JerryScript site links it with IoT.js, a related JavaScript platform for IoT applications. Package-manager adoption through Homebrew and Nix gives developers a straightforward way to build and experiment with the `jerry` command-line engine on workstations, even though the project's natural deployment target is embedded firmware and constrained devices. ### 使われ方 The repository documents a simple source build with `python tools/build.py`, producing the `jerry` executable. Library users embed the engine through its C API, while the snapshot mechanism allows JavaScript source to be precompiled to bytecode before deployment. ### パッケージ好きにとっての重要性 JerryScript is interesting to package people because it is not another desktop JavaScript runtime. It packages a tiny embeddable engine whose constraints are closer to firmware than Node.js, making it a useful test case for how package managers expose embedded-runtime tooling to general-purpose developer machines. ### タイムライン - 2015: Public GitHub repository created for jerryscript-project/jerryscript. - 2016: JerryScript 1.0 released on GitHub. - 2019: JerryScript 2.0 released on GitHub. - 2024: JerryScript 3.0.0 release notes report broader ECMAScript feature coverage. ### Related projects - JerryScript is related to IoT.js through the project site's Powering IoT.js link and to the OpenJS Foundation project family through OpenJS hosting. ### ソース - - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## 他のパッケージマネージャ記録 - Nix - jerryscript: normalized package name match | nixpkgs package indexes: pkgs/by-name/je/jerryscript/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
