hashupDeterministic import hashing

Resolves every import and produces a fully deterministic hash for any entry file.

Fully Deterministic

Same inputs always produce the same SHA-256 hash — safe for caching, invalidation, and content addressing.

Transitive Resolution

Walks every `import` in your entry file and all its dependencies using `enhanced-resolve`, respecting tsconfig paths, package exports, and conditional imports.

Multi-Format

Handles `.ts`, `.tsx`, `.js`, `.jsx`, `.mjs`, `.mts`, `.cjs`, `.json`, and more out of the box.

Extras Support

Include arbitrary files (e.g. `package.json`, lockfiles, config) in the hash to catch environment changes.

Library or CLI

Import `hashup()` from Node, or run the `hashup` binary against a `hashup.json` config with any number of named entries.
