我正在爲Angular創建一個小的npm包,這基本上是一個指令,可以拖放/移動您放置的元素。我確實設法在昨天發佈它(甚至認爲它需要一段時間,因爲這是我第一次發佈角度包到npm)。我使用ngc
來編譯Angular的代碼。彙總捆綁和unlify縮小。角度編譯器輸出包含未定義的腳本
現在,我想修復我發現的一些錯誤。我修正了它們,運行了編譯器,跑起來了,等等。但是彙總顯示我沒有定義@angular/core
,所以它將它視爲外部依賴項,以及我在解決問題時遇到的問題 - 即我的兩個文件中的this is undefined
https://github.com/rollup/rollup/wiki/Troubleshooting#this-is-undefined)。無論如何,模塊建成了,我可以發佈它並使用它。問題是,當我嘗試ng build --prod --aot
包含它破口大罵包中的應用:
ERROR in Unexpected value
'DragOnlyModule in .../ng-dragonly-demo/node_modules/ng-dragonly/index.d.ts'
imported by the module
'AppModule in .../ng-dragonly-demo/src/app/app.module.ts'.
Please add a @NgModule annotation.
我想這是因爲發生在警告我上面寫的。所以我試圖解決它們,但沒有成功。我至少能夠通過將exports: ['@angular/core']
添加到rollup.config.js
文件中來修復@angular/core
警告,但this is undefined
仍然存在。我也意識到我編譯的文件與昨天的文件不同。
幾次提交之前編譯的文件,等:
import { NgModule } from "@angular/core";
import { DragOnlyDirective } from "./dragonly.directive";
var DragOnlyModule = (function() {
function DragOnlyModule() {
}
DragOnlyModule.decorators = [
{ type: NgModule, args: [{
declarations: [DragOnlyDirective],
exports: [DragOnlyDirective]
},] },
];
/** @nocollapse */
DragOnlyModule.ctorParameters = function() { return []; };
return DragOnlyModule;
}());
export { DragOnlyModule };
//# sourceMappingURL=dragonly.module.js.map
編譯的文件今天:
var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {
var c = arguments.length, r = c < 3 ? target : desc === null ? desc = Object.getOwnPropertyDescriptor(target, key) : desc, d;
if (typeof Reflect === "object" && typeof Reflect.decorate === "function") r = Reflect.decorate(decorators, target, key, desc);
else for (var i = decorators.length - 1; i >= 0; i--) if (d = decorators[i]) r = (c < 3 ? d(r) : c > 3 ? d(target, key, r) : d(target, key)) || r;
return c > 3 && r && Object.defineProperty(target, key, r), r;
};
import { NgModule } from "@angular/core";
import { DragOnlyDirective } from "./dragonly.directive";
var DragOnlyModule = (function() {
function DragOnlyModule() {
}
DragOnlyModule = __decorate([
NgModule({
declarations: [DragOnlyDirective],
exports: [DragOnlyDirective]
})
], DragOnlyModule);
return DragOnlyModule;
}());
export { DragOnlyModule };
//# sourceMappingURL=dragonly.module.js.map
它看起來像裝飾創建不同,我真的有Ø想法,如果我已經改變了tsconfig.json
文件或任何其他配置文件中的任何內容。
我在做建立我的模塊的步驟如下:
node_modules/.bin/ngc -p tsconfig.json
node_modules/.bin/rollup -c
node_modules/.bin/uglify ... (that's a long one)
我的文件結構是:
app
|
- src/
- dragonly.directive.ts
- dragonly.module.ts
- index.ts
- package.json
- tsconfig.json
- rollup.config.js
...並且我將輸出編譯到應用程序根目錄下的dist/
目錄中。
