一个自动添加用try catch包裹await的插件

开发调试

0、npm install

1、yarn test

提供给其他人用

npm publish发布,会预先执行npm run prepare

示例：

1、声明函数

编译前

async function fetchGet() {
  const res = await fetch('https://httpbin.org/get').then(res => res.json());
  return res;
}

编译后

async function fetchGet() {
  try {
    const res = await fetch('https://httpbin.org/get').then(res => res.json());
    return res;
  } catch (e) {
    console.log('error', e);
  }
}

2、箭头函数

编译前

const arrowFun = async () => {
  const res = await fetch('https://httpbin.org/post').then(res => res.json());
  return res;
}

编译后

const arrowFun = async () => {
  try {
    const res = await fetch('https://httpbin.org/post').then(res => res.json());
    return res;
  } catch (e) {
    console.log('error', e);
  }
};

3、没有包裹体的箭头函数

编译前

const arrowFunWithoutBody = async () => await fetch('https://httpbin.org/get/arrow');

编译后

const arrowFunWithoutBody = async () => {
  try {
    return await fetch('https://httpbin.org/get/arrow');
  } catch (e) {
    console.log('error', e);
  }
};

4、用if包裹await

编译前

const wrapWithIfFun = async () => {
  if ('True') {
    const res = await fetch('https://httpbin.org/get/arrow');
    return res;
  }
};

编译后

const wrapWithIfFun = async () => {
  try {
    if ('True') {
      const res = await fetch('https://httpbin.org/get/arrow');
      return res;
    }
  } catch (e) {
    console.log('error', e);
  }
};

5、已经被tryCatch包裹

编译前

const awaitWrapByTryCatchFun = async () => {
  try {
    const res = await fetch('https://httpbin.org/post').then(res => res.json());
    return res;
  } catch (err) {
    console.log('自定义捕捉错误');
  }
}

编译后

const awaitWrapByTryCatchFun = async () => {
  try {
    const res = await fetch('https://httpbin.org/post').then(res => res.json());
    return res;
  } catch (err) {
    console.log('自定义捕捉错误');
  }
};
