Build reusable Shiny modules with proper namespace isolation using NS(). Covers module UI/server pairs, reactive return values, inter-module communication, and nested module composition. Use when extracting a reusable component from a growing Shiny app, building a UI widget used in multiple places, encapsulating complex reactive logic behind a clean interface, or composing larger applications from smaller, testable units.
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
# Build Shiny Module Create reusable Shiny UI/server module pairs with proper namespace isolation, reactive communication, and composability. ## When to Use - Extracting a reusable component from a growing Shiny app - Building a UI widget that will be used in multiple places - Encapsulating complex reactive logic behind a clean interface - Composing larger applications from smaller, testable units ## Inputs - **Required**: Module purpose and functionality description - **Required**: Input/output contract (what the module receives and returns) - **Optional**: Whether the module nests other modules (default: no) - **Optional**: Framework context (golem, rhino, or vanilla) ## Procedure ### Step 1: Define the Module Interface Before writing code, define what the module accepts and returns: ```text Module: data_filter Inputs: reactive dataset, column names to filter on Outputs: reactive filtered dataset UI: filter controls (selectInput, sliderInput, dateRangeInput) ``` **Got:** Clear contract specifying reactive inputs, reactive outputs, and UI elements. …

How to install
mdr add pjt222/agent-almanac/build-shiny-module@sha256:842705540e1afe08The line at the top of this page pins the label v1.0, 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.
