目前我正在尝试创建我的第一个 Angular 2 库,即翻译管道。现在我正在尝试让开发人员能够将带有翻译的对象插入到模块中,以便管道可以使用它。
如何将某种配置/对象插入到我的库中,以便我的所有组件、管道和服务都可以使用它?
我的图书馆看起来像:
index.ts
import { NgModule, ModuleWithProviders } from '@angular/core';
import { CommonModule } from '@angular/common';
import { TranslatePipe } from './translate.pipe';
export * from './translate.pipe';
@NgModule({
imports: [
CommonModule
],
declarations: [
TranslatePipe
],
exports: [
TranslatePipe
]
})
export class TranslateModule
{
static forRoot(): ModuleWithProviders
{
return {
ngModule: TranslateModule,
providers: []
};
}
}
翻译.pipe.ts
import { Injectable, PipeTransform, Pipe } from '@angular/core';
@Pipe({
name: 'translate'
})
@Injectable()
export class TranslatePipe implements PipeTransform
{
public translations: any = null;
constructor ()
{
this.translations = {};
}
transform(key: string): string
{
let translation = key;
if (key in this.translations) translation = this.translations[key];
return translation;
}
}
我的测试项目:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { TranslateModule } from 'translate-pipe';
@NgModule({
declarations: [
AppComponent,
TranslateModule
],
imports: [
BrowserModule,
FormsModule,
HttpModule
],
providers: [
TranslateModule
],
bootstrap: [AppComponent]
})
export class AppModule { }
