GoGoCode

如果你想这样转换代码

与 Babel 对比

与 jscodeshift 对比

原代码


  import a from 'a';
  console.log('get A');
  var b = console.log();
  console.log.bind();
  var c = console.log;
  console.log = func;

转换后


  import a from 'a';
  var b = void 0;
  console.log.bind()
  var c = function(){};
  console.log = func

用 Babel 要这么写


  module.exports = function({ types: t }) {
    return {
        name: "transform-remove-console",
        visitor: {
        CallExpression(path, state) {
            const callee = path.get("callee");
    
            if (!callee.isMemberExpression()) return;
    
            if (isIncludedConsole(callee, state.opts.exclude)) {
            // console.log()
            if (path.parentPath.isExpressionStatement()) {
                path.remove();
            } else {
            //var a = console.log()
                path.replaceWith(createVoid0());
            }
            } else if (isIncludedConsoleBind(callee, state.opts.exclude)) {
            // console.log.bind()
                path.replaceWith(createNoop());
            }
        },
        MemberExpression: {
            exit(path, state) {
            if (
                isIncludedConsole(path, state.opts.exclude) &&
                !path.parentPath.isMemberExpression()
            ) {
            //console.log = func
                if (
                path.parentPath.isAssignmentExpression() &&
                path.parentKey === "left"
                ) {
                path.parentPath.get("right").replaceWith(createNoop());
                } else {
                //var a = console.log
                path.replaceWith(createNoop());
                }
            }
            }
        }
        }
    };

用 GoGoCode 呢？


  $(code)
  .replace(`var $_$ = console.log()`, `var $_$ = void 0`)
  .replace(`var $_$ = console.log`, `var $_$ = function(){}`)
  .find(`console.log()`)
  .remove()
  .generate();
