instalar - Cómo importar core-js Map en la aplicación generada angular-cli webpack

angular material

Question

^ 1.0.0-beta.11-webpack "ahora usa core-js para polyfills.

Estoy tratando de importar un mapa para usar en mi aplicación

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
}

Incluso he agregado el archivo core-js d.ts usando

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

sin embargo, ninguna de las importaciones resuelve el símbolo del mapa.

¿Qué me estoy perdiendo?

EDIT 1 | Errores generados

Ahora puedo usar la entidad Map, pero estoy obteniendo muchos errores en el cosole, aunque puedo establecer / obtener claves / valores del mapa

Answer 1

El problema aquí es que las declaraciones para core-js redeclaran muchos tipos que proporciona TypeScript e incluye por defecto.

core-js pretende rellenar las especificaciones actuales y futuras de la biblioteca estándar de ECMAScript. TypeScript busca describir los tipos de esas mismas especificaciones actuales y futuras.

Las declaraciones de tipo disponibles para core-js solapan con las proporcionadas por el lenguaje.

Tiene algunas opciones sólidas que puede usar:

1. En tsconfig.json, especifique "noLib": true en "compilerOptions" para indicar a TypeScript que se abstenga de incluir automáticamente sus declaraciones de biblioteca estándar integradas en el contexto de compilación.
2. En tsconfig.json, especifique la opción "lib" , que le proporciona un control más detallado sobre las declaraciones de biblioteca estándar incluidas. Por ejemplo, puede especificar "lib": ["es2017.symbol.wellknown", "dom"] .
3. Desinstale el paquete @ types / core-js y simplemente use los archivos de declaración incorporados de TypeScript como se "lib": ["es2017", "dom"] anteriormente especificando "lib": ["es2017", "dom"] . Continuará utilizando core-js , pero usará las propias definiciones de TypeScript para escribir la implementación.

Después de pasar un tiempo yendo y viniendo entre estas opciones, me parece que la opción 3 es la más fácil de mantener.

Tenga en cuenta que los archivos de declaración incluidos automáticamente por TypeScript dependen de la propiedad "target" en tsconfig.
