Maybe is useful for someone, I leave a link to our github repository with vim snippets for meteor. It’s an old fork from cmather repo, creator of Iron Router, but quite different now.
https://github.com/ixdi/vim-meteor-snippets
I don’t know if the format is exportable to other editors.
html snippets are for Blaze templates but there’s no problem in adding React or other tech snippets and have a meteor snippets repo.
