I want to set up an eslint rule for this scenario:
// incorrect
[
'onClickSave',
'onClickCancel'].forEach(bind(this));
// correct
[
'onClickSave',
'onClickCancel'
].forEach(bind(this));
When declaring an object or array with multiple lines, the brackets should be on a new line.
Is there an existing eslint rule for this, or how can I achieve it?
There aren't currently any eslint rules specifically addressing this issue, but discussions are ongoing regarding potential rules such as array-bracket-newline and array-element-newline.
JSCS provides a rule called
validateNewlineAfterArrayElements"validateNewlineAfterArrayElements": {
"maximum": 1
}
For instance, if there is more than one element in the array, each should be on its own line.
"newline-after-array-element": [
"error",
'always'
],
Implementing the above code will ensure a newline after each element in an array.
Additionally, consider using:
"newline-after-array-bracket": [
"error",
{
"minItems": 1,
},
],
This would be my recommended approach as well.
