ES6承诺/打字稿和蓝鸟承诺 [英] ES6 Promise / Typescript and the Bluebird Promise
问题描述
我有一个nodejs / typescript 2项目，并使用 es6-promise 软件包。
现在我想摆脱额外的包，因为我可以直接在打字稿中定位ES6。
I have a nodejs / typescript 2 project and use the es6-promise package. Now i would like to get rid of the extra package because i can target ES6 in typescript directly.
所以我删除了es6-promise软件包并将tsconfig.json更改为目标es6。
So i removed the es6-promise package and changed the tsconfig.json to target es6.
{
"compilerOptions": {
"target": "es6",
// ...
}
}
许多第三方软件包使用Bluebird承诺，但承诺定义与默认的es6承诺不相容，如不同github上的帖子
Many 3rd party packages uses the Bluebird promise but the promise definition is incompatible to the default es6 promise as stated on different posts on github
- bluebird 3.0 definifion is not assignable to ES6 Promises
- Provide a way to load Bluebird globally in es6 compilation target.
- Add Symbol.toStringTag to promise instance
所以我收到以下错误。
TS2322：类型'Bluebird'不能分配给'Promise'类型。 Bluebird类型中缺少[Symbol.toStringTag]属性。
TS2322: Type 'Bluebird' is not assignable to type 'Promise'. Property '[Symbol.toStringTag]' is missing in type 'Bluebird'.
npm @ types / bluebird-global 。
在其中一篇博文中，用户建议使用它而不是 @ types / bluebird 但是一些第三方软件包（例如sequelize typings）引用了bluebird而不是bluebird-global所以我得到了蓝鸟缺失的另一个错误。
There is a other types package on npm @types/bluebird-global. In one of the blog post a user suggests to use it instead of @types/bluebird but some 3rd party packages (e.g. sequelize typings) reference bluebird and not bluebird-global so i get another error for the missing typings of bluebird.
什么是一个很好的解决方案让这个工作？
What is a good solution to get this to work?
推荐答案
我正在处理
TS2322：类型'Bluebird'不能分配给'Promise'类型。属性'[Symbol.toStringTag]'在'Bluebird'类型中缺失。
TS2322: Type 'Bluebird' is not assignable to type 'Promise'. Property '[Symbol.toStringTag]' is missing in type 'Bluebird'.
并找到此主题：
https://github.com/DefinitelyTyped/DefinitelyTyped/issues/10801
TL; DR;它的版本是执行以下操作之一：
The TL;DR; version of it is to do one of the following:
-
在每个.ts条目文件中添加以下内容以覆盖全球承诺：
In each of your .ts entry files add the following to overwrite the global promise:
从'bluebird'导入*作为Bluebird;
声明全局{export interface Promise< T>扩展Bluebird< T> {}}
或
- 在Bluebird promise构造函数中包装所有promise。这里有一些运行时开销，它在Bluebird的站点上被列为反模式。
顺便说一句，我无法获得第二种选择，但第一种选择对我来说没问题。
As an aside, I could not get the second option to work, but the first worked fine for me.
