ESclean is a helpful tool that allows you to track down and remove unused exports in EcmaScript-compatible JavaScript projects.

The goal is to support both JavaScript and TypeScript source code analysis.

Run: esclean path/to/indexFile.ts|js

It will stream a list of unused exports to stdout. Please double check in your IDE that they aren't used before removing them.

Given an index file, the algorithm traverses the entire source code hierarchy while ignoring third-party packages, following import paths as far as possible. Each import is checked against a matching export statement from the source and, if matched, a reference counter is incremented. Finally, a report is generated containing all unmatched exports.

In the early stages of this project, some false positives must be expected. But once a list of candidates exist, it should be faily easy to double check them in your IDE before removing any unused exports.

• Does not handle multiline imports / exports
• Files imported by alias (namespaced) are assumed to have been used
• Does not work with CommonJS
• Has no notion of "TypeScript" or "JavaScript" mode, which could give unpredictable results
• Does not check if imports are actually used
• Generated file hashes were introduced to improve lookup speeds, but are currently unused

The author does not take responsibility for broken code that results from an analysis made by ESclean. A fair amount of thoughtfulness must be expected.
