Use when writing or reviewing modern JavaScript for browser or PHP-backed SaaS applications, including modules, asynchronous flows, error handling, language features, and performance.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# javascript-modern Acknowledgement: Shared by Peter Bamuhigire, techguypeter.com, +256 784 464178. <!-- dual-compat-start --> ## Use When - Modern JavaScript (ES6+) patterns for PHP+JavaScript SaaS apps: modules, async/await, destructuring, Proxy/Reflect, generators, WeakMap/WeakSet, optional chaining, error handling, and performance patterns. Use when writing JavaScript for web... ## Workflow - For OOP-heavy browser modules, reusable UI widgets, or complex stateful workflows, pair with `references/javascript-patterns.md` and load `references/javascript-patterns.md`. - For Node/runtime container work, pair with `docker-development`. ## Evidence Produced | Category | Artifact | Format | Example | |----------|----------|--------|---------| | Correctness | JavaScript module test plan | Markdown doc covering async, generators, Proxy, and module boundary tests | `docs/web/js-module-tests.md` | ## References - Use the `references/` directory for deep detail after reading the core workflow below. - Use `references/javascript-advanced.md` when the task needs deeper ES language mechanics, async patterns, metaprogramming, or performance. …

How to install
mdr add peterbamuhigire/chwezi-dev-engine/javascript-modern@sha256:5b0e6316f22fd068The line at the top of this page pins the label git:20260712.a867952, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
