JSharpener — JS/TS static analysis
TypeScript Compiler API-based analyzer (sibling of CSharpener). Runs on any JS/TS project without it needing to compile.
Running it
node "C:\Users\matthew.heath\Git\JSharpener\dist\cli\index.js" <command> [path]
If dist\cli\index.js is missing, rebuild: cd C:\Users\matthew.heath\Git\JSharpener && npm install && npm run build
Commands
analyze [path] — project overview (files/functions/classes/imports/exports)treeshake [path] --entry src/index.ts — unused exports, functions, variables, imports. Always pass --entry (repeatable) or reachability is guessed and results are noisy.callgraph [path] -o out.dot --function processData — Graphviz DOT call graph focused on a function; add --reverse for "who calls this"; --depth <n> to limit; --module-level for an architecture-level module dependency viewdeps [path] --circular — circular dependency chains; --external for external package usage
Common flags: --include "src/**/*.ts", --exclude "**/*.test.ts", -o <file>, --format json (treeshake), --config jsharpener.json (include/exclude/entryPoints in one place).
Known limitations (first version)
Method calls through object instances aren't fully tracked in call graphs; dynamic import() and JSX/TSX support is limited — treat treeshake results on React code as suggestions, not proof.
