Expand description
Build and query dependency graphs for TypeScript/JavaScript and Python codebases.
Chainsaw parses import statements, resolves them against the filesystem, and constructs a full transitive dependency graph from any entry file. The graph can then be queried for total import weight, heaviest packages, shortest import chains, optimal cut points, and before/after diffs.
This library backs the chainsaw CLI. The public API is internal and
unstable – it exists so benchmarks and tests can access internals.
