如何将 core-js Map 导入到 angular-cli webpack 生成的应用程序中

问题描述

^1.0.0-beta.11-webpack"现在使用 core-js 进行 polyfill.

^1.0.0-beta.11-webpack" now uses core-js for polyfills.

我正在尝试导入地图以在我的应用程序中使用

I am trying to import a Map for use in my application

import {Map} from 'core-js/es6/map'
//import {Map} from 'core-js/library/es6/map'

export function updatePayload(data: any, isDataValid: boolean): Map<string, any> {
  const payload: Map<string, any> = new Map<string, any>()
  payload.set('data', data)
  payload.set('isDataValid', isDataValid)
  return payload
}

我什至使用

npm install --save @types/core-js (typescript 2.0 is used)

然而，这两个导入都没有解析 Map 符号.

yet neither of the imports resolves the Map symbol.

我错过了什么?

我现在可以使用 Map 实体，但是我在 cosole 中遇到了很多错误，即使我可以设置/获取地图键/值

I can now use the Map entity, but I am getting a lot of errors in the cosole, even though I can set/get map keys/values

推荐答案

这里的问题是 core-js 的声明重新声明了 TypeScript 本身默认提供和包含的许多类型.

The issue here is that the declarations for core-js redeclare many types that TypeScript itself provides and includes by default.

core-js 旨在填充 ECMAScript 标准库当前和未来的规范.TypeScript 旨在描述那些相同的当前和未来规范的类型.

core-js aims to polyfill the current and future specifications of the ECMAScript standard library. TypeScript aims to describe the types of those same current and future specifications.

core-js 可用的类型声明因此与语言提供的类型声明重叠.

The type declarations available for core-js thusly overlap with those provided by the language.

您可以使用一些可靠的选项:

You have a few solid options that you can use:

1. 在 tsconfig.json 中，在 "compilerOptions" 下指定 "noLib": true 以指示 TypeScript 避免在编译上下文中自动包含其内置的标准库声明.
2. 在 tsconfig.json 中指定 "lib" 选项，它可以让您更精细地控制包含哪些标准库声明.例如，您可以指定 "lib": ["es2017.symbol.wellknown", "dom"].
3. 卸载@types/core-js 包，并通过指定"lib": ["es2017", "dom"] 简单地使用TypeScript 的内置声明文件.您将继续使用 core-js，但您将使用 TypeScript 自己维护良好的定义来输入实现.

1. In tsconfig.json specify "noLib": true under "compilerOptions" to instruct TypeScript to refrain from automatically including its built in standard library declarations in the compilation context.
2. In tsconfig.json specify the "lib" option which gives you more granular control over which standard library declarations are included. For example you might specify "lib": ["es2017.symbol.wellknown", "dom"].
3. Uninstall the @types/core-js package and simply use TypeScript's built in declaration files as above by specifying "lib": ["es2017", "dom"]. You will continue to use core-js, but you will be using TypeScript's own well-maintained definitions to type the implementation.

在我自己花了一些时间在这些选项之间来回切换之后，我发现选项 3 是最容易维护的.

After spending some time going back and forth between these options myself, I find that option 3 is the easiest to maintain.

请注意，TypeScript 自动包含的声明文件依赖于 tsconfig 中的 "target" 属性.

Please note that the declaration files automatically included by TypeScript depend on the the "target" property in tsconfig.
