babel-plugin-logfunctionname

A babel plugin to insert a log in function to show the function name

if you join in a large project but with no document, this plugin maybe could help you;

In

const functionName = function () {
 
}
function functionHere() {
 
}
const arrowFunction = () => {
 
}
class ClassFunction {
  constructor(name) {
    this.name = name;
  }
  seyHello() {
    console.log(`hello ${this.name}`)
  }
}
let classFunctionItem = new ClassFunction('sz-p')
 
functionName();
functionHere();
arrowFunction();
classFunctionItem.seyHello();

out

"use strict";
 
function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }
 
function _defineProperties(target, props) { for (var i = 0; i < props.length; i++) { var descriptor = props[i]; descriptor.enumerable = descriptor.enumerable || false; descriptor.configurable = true; if ("value" in descriptor) descriptor.writable = true; Object.defineProperty(target, descriptor.key, descriptor); } }
 
function _createClass(Constructor, protoProps, staticProps) { if (protoProps) _defineProperties(Constructor.prototype, protoProps); if (staticProps) _defineProperties(Constructor, staticProps); return Constructor; }
 
var functionName = function functionName() {
  console.log("function_working:functionName");
};
 
function functionHere() {
  console.log("function_working:functionHere");
}
 
var arrowFunction = function arrowFunction() {
  console.log("function_working:arrowFunction");
};
 
var ClassFunction =
/*#__PURE__*/
function () {
  function ClassFunction(name) {
    console.log("function_working:ClassFunction");
 
    _classCallCheck(this, ClassFunction);
 
    this.name = name;
  }
 
  _createClass(ClassFunction, [{
    key: "seyHello",
    value: function seyHello() {
      console.log("function_working:seyHello");
      console.log("hello ".concat(this.name));
    }
  }]);
 
  return ClassFunction;
}();
