typescript - 克服 Meteor/Typescript/Angular 编译器丢失错误

Question

我遇到了几种类型的错误，我可以在 Meteor/Angular 代码中编写这些错误，这些错误似乎会破坏编译器而不会引发错误。一些例子:

export const foo = {
  propA: 'abc',
  propB: 123;
  propc: 'value'
}

对象中间的分号错误地破坏了事物。
其他:

private _functionName( param1: string, param2: boolean; param3: string ): void { // do stuff here  }

分号又被错误地放置在哪里。第三:

const propertyName = thisArray.map( thing => return thing._id );

回调函数应该用大括号括起来(分号可能也有帮助)。第四:

import style    from './this.component.scss';

其中指定的 .scss 文件不存在(如果它存在但 0 字节将通过 - 只有它不存在的情况才会失败)。

这些错误中的每一个都会导致在服务器端进行干净的编译，并在加载屏幕上挂起一个应用程序的无错误客户端控制台。

存在是否/如何重现的问题；下面是我在 Amazon Linux 上工作的具体环境参数。

那么，我的问题是:

是否存在有助于故障排除的 linter 或一些我没有看到的调试器日志？我认识到某些 IDE 会突出显示这些错误(尤其是缺少的 SCSS 文件)，但这并不能回答我的问题。

提前致谢!

Answer 1

我不确定您的问题是什么，但是在您使用默认编译器设置提到的所有情况下，我都会遇到错误。以下片段:

import style    from './bla'; // with bla.js being an empty file

export const foo = {
  propA: 'abc',
  propB: 123;
  propc: 'value'
}

function _functionName( param1: string, param2: boolean; param3: string ): void {}

产生以下输出:

test.ts(5,13): error TS1005: ',' expected.
test.ts(10,56): error TS1005: ',' expected.

虽然空模块不会产生编译器错误，但它会在 VS Code 中警告您这一点。

如果你想要一个用于 Typescript 的 linter，tslint 是一个很棒的工具。但是你的前两个肯定是编译器错误(至少在 TS 2.5 中)
