Limit Maximum Number of Statements (max-statements)

The max-statements rule allows you to specify the maximum number of statements allowed in a function.

function foo() {
  var bar = 1; // one statement
  var baz = 2; // two statements
  var qux = 3; // three statements
}

Rule Details

This rule allows you to configure the maximum number of statements allowed in a function. The default is 10.

Options

There is an additional optional argument to ignore top level functions.

"max-statements": [2, 10, {"ignoreTopLevelFunctions": true}]

The following patterns are considered problems:

/*eslint max-statements: [2, 2]*/  // Maximum of 2 statements.
function foo() { /*error This function has too many statements (3). Maximum allowed is 2.*/
  var bar = 1;
  var baz = 2;

  var qux = 3; // Too many.
}

The following patterns are not considered problems:

/*eslint max-statements: [2, 2]*/  // Maximum of 2 statements.
function foo() {
  var bar = 1;
  return function () {

    // The number of statements in the inner function does not count toward the
    // statement maximum.

    return 42;
  };
}

/*eslint max-statements: [2, 1, {ignoreTopLevelFunctions: true}]*/  // Maximum of 1 statement.
(function() {
  var bar = 1;
  return function () {
    return 42;
  };
})()

Version

This rule was introduced in ESLint 0.0.9.
