      {

demo

原始代码：

async function fn() {
  await new Promise((resolve, reject) => reject('报错'));
  await new Promise((resolve) => resolve(1));
  console.log('do something...');
}
fn();

使用插件转化后的代码：

async function fn() {
  try {
    await new Promise((resolve, reject) => reject('报错'));
    await new Promise((resolve) => resolve(1));
    console.log('do something...');
  } catch (e) {
    console.log('\nfilePath: E:\\myapp\\src\\main.js\nfuncName: fn\nError:', e);
  }
}
fn();
