eslintd-fix
Minor-mode to automatically fix javascript with eslint_d. Built with a focus on speed, you will typically barely notice a delay when saving, if at all.
Note that this package will not show errors, only fix them on save. You'll want to configure flycheck to use eslint_d as well.
This package was recently rewritten to use a direct network connection to eslint_d rather than a node shell command. This is significantly faster, but could have introduced bugs. If you notice anything out of the ordinary, please report it.
Installation
You can install this package from Melpa
M-x package-install RET eslintd-fix RET
