Eslint 规则“padding-line-between-statements”没有按预期工作

Question

I am trying to configure eslint to force newlines after return statements and block openings using the padding-line-between-statements rule. Enforcing a newline before the return works well but I can't get it after by just swapping prev/next.

Here is what I tried in eslintrc.js

"padding-line-between-statements": [ "warn",
        { blankLine: "always", prev: "return", next: "*" }
]

What am I missing? Shouldn't it work like this as described in documentation ? Or is there a better rule for wrapping block content in new lines?

Answer 1

The padding-line-between-statements rule works adding a padding line between two statements. As there is no statement after the return it won't never work. The wildcard * means "any statements", but that doesn't mean anything . There is a list of valid statement types in the docs .

Anyways, check out the Google JavaScript Style Guide :

[A single blank line appears] within method bodies, sparingly to create logical groupings of statements. Blank lines at the start or end of a function body are not allowed.

Of course it's just a style guide, but I thought it's interesting to have in mind that Google considers that a bad practice style-wise.
