The project site and README emphasize microcontroller-class memory budgets, C99 portability, on-device compilation and execution, bytecode snapshots, and an embeddable C API. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** jerryscript - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - 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 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Web development packages](https://www.automicvault.com/pkg/web-dev-tools/) - Matched web development metadata. - [cmake](https://www.automicvault.com/pkg/brew/cmake/) - Build dependency declared by Homebrew. - [boa](https://www.automicvault.com/pkg/brew/boa/) - Shares av.db curated category or tags: cli, ecmascript, engine, javascript, language-runtime. - [duktape](https://www.automicvault.com/pkg/brew/duktape/) - Shares av.db curated category or tags: cli, ecmascript, javascript, language-runtime. - [mujs](https://www.automicvault.com/pkg/brew/mujs/) - Shares av.db curated category or tags: cli, embedded, javascript, language-runtime. - [v8](https://www.automicvault.com/pkg/brew/v8/) - Shares av.db curated category or tags: cli, engine, javascript, language-runtime. - [deno](https://www.automicvault.com/pkg/brew/deno/) - Shares av.db curated category or tags: cli, javascript, language-runtime. - [fibjs](https://www.automicvault.com/pkg/brew/fibjs/) - Shares av.db curated category or tags: cli, javascript, language-runtime. - [gjs](https://www.automicvault.com/pkg/brew/gjs/) - Shares av.db curated category or tags: cli, javascript, language-runtime. - [node](https://www.automicvault.com/pkg/brew/node/) - Shares av.db curated category or tags: cli, javascript, language-runtime. ## Combined YAML source View the package source record on GitHub.
