Hi,
I would like to work on this issue, I checked the URl, it is mentioned jsx-space-before-closing rule is deprecated and suggested to use jsx-tag-spacing with rule options beforeSelfClosing which can be set to "always or never".

Tslint rule jsx-space-before-trailing-slash has no arguments and it means always, so for eslint rule jsx-tag-spacing
below object is constant. can i go ahead with this assumption ?
{
"closingSlash": "never",
"beforeSelfClosing": "always",
"afterOpening": "never",
"beforeClosing": "allow"
}

From TSLint:

Checks that self-closing JSX elements have a space before the '/>' part.

From ESLint:

https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/jsx-tag-spacing.md#beforeselfclosing

Seems to be only for beforeSelfClosing only ("always" in this case), as the originalTSLint only checks for /> tag.
