Angular SystemJS:加载构建文件
我的SystemJS文件如下所示:Angular SystemJS:加载构建文件,angular,systemjs,tsc,Angular,Systemjs,Tsc,我的SystemJS文件如下所示: (function(global) { // map tells the System loader where to look for things var map = { 'angular2-boot': 'app', // 'dist', '@angular': 'node_modules/@angular', 'angular2-in-memory-web-a
(function(global) {
// map tells the System loader where to look for things
var map = {
'angular2-boot': 'app', // 'dist',
'@angular': 'node_modules/@angular',
'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
'rxjs': 'node_modules/rxjs'
};
// packages tells the System loader how to load when no filename and/or no extension
var packages = {
// 'app': { main: 'js/main.js', defaultExtension: 'js' },
'app': { main: 'dist/build.js', defaultExtension: 'js' },
'rxjs': { defaultExtension: 'js' },
'angular2-in-memory-web-api': { defaultExtension: 'js' }
};
var ngPackageNames = [
...
];
// Add package entries for angular packages
ngPackageNames.forEach(function(pkgName) {
packages['@angular/'+pkgName] = { main: pkgName + '.umd.js', defaultExtension: 'js' };
});
var config = {
map: map,
packages: packages
};
System.config(config);
})(this);

在本文中,我使用tsconfig.js中的outDir选项将我的typescript传输到另一个目录中,并在使用main的包中引用该选项:“js/main.js”,这很好
然而,当我尝试使用outFile选项将文件传输到单个文件中,并使用main引用该文件时:“dist/build.js”。它不会呈现页面,我在控制台中也没有看到任何错误
My index.html如下所示:

上面说加载。。。当我加载页面时。使用SystemJS加载单个输出传输文件需要进一步做什么?当您传输到单个文件时,它会生成一个名为“bundle”的特殊格式的文件。导入时,其中的所有模块都会加载并在SystemJS中注册,但不会执行任何操作。因此,加载捆绑包后,您需要在
index.html
中添加第二个导入,它将实际启动您的应用程序,如下所示:
(function(global) {
// map tells the System loader where to look for things
var map = {
'angular2-boot': 'app', // 'dist',
'@angular': 'node_modules/@angular',
'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
'rxjs': 'node_modules/rxjs'
};
// packages tells the System loader how to load when no filename and/or no extension

};
var ngPackageNames = [
...
];
// Add package entries for angular packages
ngPackageNames.forEach(function(pkgName) {
packages['@angular/'+pkgName] = { main: pkgName + '.umd.js', defaultExtension: 'js' };
});

System.config(config);

此代码使用显式路径加载捆绑包:app/dist/build.js
,然后加载名为main
的模块,因为该名称必须与捆绑包中的define
调用中给出的模块名称完全匹配。因此,此代码中没有任何内容引用angular boot
或app
包,因为它是在systemjs.config.js
中定义的,因此该文件中没有任何内容需要更改
也可以加载带有普通
标记的捆绑包,然后只需要一个System.import('main')

。查看浏览器中的网络选项卡,因为我怀疑没有加载文件。我看到build.js正在加载。它有200个返回代码,我还可以看到build.js源代码。请查看浏览器中的“网络”选项卡,因为我怀疑没有加载文件。我看到build.js正在加载。它有200个返回代码,我还可以看到build.js的源代码。
