Disallow or enforce spaces inside of blocks after opening block and before closing block (block-spacing)

Rule Details

This rule enforces consistent spacing inside an open block token and the next token on the same line. This rule also enforces consistent spacing inside a close block token and previous token on the same line.

Options

This rule has a string option:

  • "always" (default) requires one or more spaces
  • "never" disallows spaces

always

Examples of incorrect code for this rule with the default "always" option:

/*eslint block-spacing: "error"*/

function foo() {return true;}
if (foo) { bar = 0;}
function baz() {let i = 0;
    return i;
}

Examples of correct code for this rule with the default "always" option:

/*eslint block-spacing: "error"*/

function foo() { return true; }
if (foo) { bar = 0; }

never

Examples of incorrect code for this rule with the "never" option:

/*eslint block-spacing: ["error", "never"]*/

function foo() { return true; }
if (foo) { bar = 0;}

Examples of correct code for this rule with the "never" option:

/*eslint block-spacing: ["error", "never"]*/

function foo() {return true;}
if (foo) {bar = 0;}

When Not To Use It

If you don't want to be notified about spacing style inside of blocks, you can safely disable this rule.

You can’t perform that action at this time.
