var includeRegexpIndexed = /=include\((.+?)(?:\)|,\s*{(.+?)}\))/g;
var str = "qqqqqqq qqqqqqqq qqqqqqqqqqqqqq let res=include('./file.eta', { name: 'eta' }) qqqqqqq qqqqqqqq qqqqqqqqqqqqqq qqqqqqq";

Tests:

named group
var result = str.replaceAll(includeRegexpNamed, `=require($<file>)({...it, ...{$<data>}})`);
indexed group
var result = str.replaceAll(includeRegexpIndexed, `=require($1)({...it, ...{$2}})`);
