  • Security Analysis: CodeQL
  • Documentation: Jekyll site published with GitHub Pages

Skills and Tooling Inventory

Capability Record

  • Strict TypeScript Compilation Contract — configures the compiler well beyond strict and runs it as a dedicated gate ahead of every build and development command, so that whole classes of defects are rejected before bundling rather than discovered in the browser.
  • Layered, Type-Aware Lint Enforcement — separates JavaScript and TypeScript lint configurations and layers type-checked rule sets over stylistic and syntax-level rules, keeping tooling code and sketch code held to appropriate, distinct standards.
  • Relocatable, Content-Hashed Production Output — emits JavaScript under content-hashed filenames and references every asset by relative path, enabling long-lived browser caching while letting the same build be served from any path on a host.
  • Single-Command Validation Gate — collapses lint, type checking, and bundling into one script that developers and CI run identically across multiple Node.js release lines, so local and automated results cannot diverge.
  • Automated Documentation Site Delivery — builds and publishes the project’s documentation site from source on every push to the default branch, keeping published guidance in step with the code it documents.
  • Continuous Security Analysis — scans the repository’s application code and its workflow definitions on merge, on proposed changes, and on a recurring schedule, so newly disclosed patterns surface without a code change to trigger them.
  • Scheduled Multi-Ecosystem Dependency Automation — tracks the JavaScript, GitHub Actions, and Ruby dependency surfaces on a shared schedule with grouped update batches, reducing the review overhead of staying current.

Detailed Technical Notes

Each technical claim below is backed by a source link to the corresponding implementation or workflow configuration in the project repository.

Strict TypeScript Compilation Contract

The TypeScript configuration enables the full strict family and layers additional compiler checks on top of it — unused locals and parameters, implicit returns, index-signature property access, unreachable code, and fallthrough switch cases — using bundler-oriented module resolution and a fixed language target shared with the lint configuration. Because Vite’s transform pipeline strips types without checking them, the project runs tsc --noEmit as a dedicated compile script that the dev, build, and preview scripts each execute first, so no entry point into the project can skip type checking.

Evidence:

Layered, Type-Aware Lint Enforcement

The repository ships two ESLint flat configurations: one scoped to JavaScript build tooling and one scoped to TypeScript sources. The TypeScript configuration layers typescript-eslint’s type-checked recommended, strict, and stylistic rule sets over @stylistic formatting rules, and both configurations use eslint-plugin-es-x to restrict syntax to the same language level the compiler targets, so lint enforcement and the build agree.

Evidence:

Relocatable, Content-Hashed Production Output

Vite writes the production build into a _dist/ directory that is cleared on each run, with entry and chunk filenames carrying short content hashes so browsers can cache aggressively without risking stale code after a release. The build is configured with a relative base, so the generated index.html links its assets by relative path and the output directory can be served from any path on a host without being rebuilt.

Evidence:

Single-Command Validation Gate

The validate script runs both lint configurations and then the build, which itself begins with the standalone tsc --noEmit type check, so a single command covers linting, type checking, and bundling. Continuous integration invokes that same script on pushes and pull requests to the default branch across a matrix of Node.js release lines, so a passing local run and a passing CI run mean the same thing.

Evidence:

Automated Documentation Site Delivery

The docs/ directory is a Jekyll site built on a remote theme with a committed dependency lockfile and a custom post layout that renders authorship, publication and modification dates, and a generated table of contents. A GitHub Actions workflow builds that site against the Pages-provided base path and deploys it as a Pages artifact, using a single non-cancelling concurrency group so that a queued run cannot interrupt a deployment already in progress.

Evidence:

Continuous Security Analysis

CodeQL analysis is configured for every language surface the repository carries — GitHub Actions workflow definitions, JavaScript and TypeScript sources, and the Ruby tooling behind the documentation site — and runs on pushes and pull requests to the default branch as well as on a recurring schedule. The analysis matrix disables fail-fast so that a failure in one language does not suppress results for the others.

Evidence:

Scheduled Multi-Ecosystem Dependency Automation

Dependabot is configured for three ecosystems: npm at the repository root, GitHub Actions workflow dependencies, and Bundler dependencies under docs/. npm updates are grouped by dependency type and separately for version and security updates, so production and development changes arrive as distinct pull requests, and each ecosystem carries its own commit-message prefix and labels so that update pull requests are routable on sight.

Evidence:

Current Gaps / Future Improvements

  • No automated test suite. The test script is a placeholder, and the validation gate covers lint, type checking, and build only. A test runner and the conventions around it are left to the project created from this template.
  • Single-entry scaffold. The template provides one HTML entry point and one sample sketch; multi-sketch routing, shared sketch utilities, and state management are deliberately out of scope.
  • Sketch output is not deployed. The Pages workflow publishes the docs/ documentation site; the bundled sketch in _dist/ is built and validated in CI but has no publishing target.
  • No bundle-size strategy. p5.js is emitted as a single chunk that exceeds Vite’s default chunk-size warning threshold, so code splitting or a tuned threshold is a natural next step for projects that ship to production.
