What rule do you want to change?


Does this change cause the rule to produce more or fewer warnings?

Possibly more.

How will the change be implemented? (New option, new default behavior, etc.)?

Modification to setting in eslint file.

  "rules": {
    "lines-between-class-members": [true, 2], <--- This right here, enforces 2 lines
  "rulesDirectory": [

Please provide some example code that this change will affect:

<!-- Put your code examples here -->

// Valid
    componentDidMount() {
        this._isMounted = true;

    componentWillUnmount() {
        this._isMounted = false;

// Invalid

    componentDidMount() {
        this._isMounted = true;
   componentWillUnmount() {
        this._isMounted = false;

What does the rule currently do for this code?

Can only be used to enforce 1 space between class members.

What will the rule do after it's changed?

Be able to enforce more than 1 space. Some people like to use 2 spaces.

Are you willing to submit a pull request to implement this change?

No I don't know how this works under the hood.

I also thought about this when I was working on PR #12663. But since the review of the changes took a long time, I left the idea with the revision for later.
