Heavy typescript dependency since v13

[medikoo]

I've just upgraded @commitlint/cli from v12 to v17, and found out that the package started to require typescript and related modules, why exactly it's the case for a such simple thing as commit message linter?

Note, that those extra packages are quite heavy and now total size of @commitlint/cli doesn't seem to be really justified

Out of the blue it could be related to adding https://github.com/Codex-/cosmiconfig-typescript-loader so people can use TS for their configs. Happy for any suggestions how to improve this.

In such case users should be responsible for ensuring TS in their own capacity.

e.g. it's exactly what we're doing in Serverless Framework, we allow users to write configuration in TS, but that doesn't make a TS tooling a mandatory dependency of the package (that'll bump our package size through the roof). Users on their own need to ensure then that ts-node is available and we crash with a meaningful error if it isn't.

Closing this in favour of #3221

@escapedcat this is still an issue; @commitlint/load depends on cosmiconfig-typescript-loader, which marks typescript as a non-optional peer dependency.

I don't use commitlint anymore so I'm not personally asking for anyone to fix this, just wanted to let you know

Even without typescript, commitlint weighs 11MB right now, almost as much as eslint (12MB). ~10MB seems pretty economical for linting JS, but seems excessive for linting commit messages.
