手写loader看console是在哪个方法调用的

//name-console-loader.js
const parser = require('@babel/parser')
const traverse = require('@babel/traverse').default
const generator = require('@babel/generator').default
const t = require('@babel/types')

module.exports = function (source) {
  const ast = parser.parse(source, { sourceType: 'module' });

  traverse(ast, {
    CallExpression(path) {
      const { callee, arguments } = path.node;

      if (t.isMemberExpression(callee) && callee.object.name === 'console' && callee.property.name === "log") {
        const parent = path.findParent(p => p.isFunctionDeclaration());
        if (parent) {
            const fnName = parent.node.id.name
            arguments.unshift(t.stringLiteral(`${fnName}:`));
        }
      }
    }
  })

  const output = generator(ast, {}, source);
  return output.code;
}

webpack loader配置，loader自右向左调，也就是从后往前调

       {
          test: /\.js$/i,
          use: [
            {
              loader: 'babel-loader',
              options: {
                  cacheDirectory: true
              }
            }, {
                loader: '../name-console-loader'
            }
          ],
          include: [path.resolve(__dirname, "app")],
        },
