我正在尝试实现Angular的AOT教程:https://angular.io/docs/ts/latest/cookbook/aot-compiler.html
使用NGC零件有效,并生成AOT文件夹。但是,当我运行应用程序时,我会得到以下错误
bundle.js:1 Uncaught ReferenceError: exports is not defined
我的代码如下: -
tsconfig-aot.json
{
"compilerOptions": {
"target": "es5",
"module": "es2015",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es2015", "dom"],
"noImplicitAny": true,
"suppressImplicitAnyIndexErrors": true
},
"files": [
"src/app/app.module.ts",
"src/main.ts"
],
"angularCompilerOptions": {
"genDir": "aot",
"skipMetadataEmit" : true
},
"exclude": [
"node_modules",
"bower_components",
"typings/main",
"typings/main.d.ts"
]
}
执行node_modules/.bin/ngc -p tsconfig -aot.json,AOT文件夹将成功生成。
main.ts
import { platformBrowser } from '@angular/platform-browser';
import { AppModuleNgFactory } from '../aot/src/app/app.module.ngfactory';
console.log('Running AOT compiled');
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);
我读了一个链接之一,即"您需要将这些TS文件编译为ES2015模块,以便从"摇摇欲坠"中受益。这意味着必须还有一个配置文件(tsconfig-compile-aot.json(仅指向main-aot.ts文件。"
tsconfig-compile-aot.json
{
"compilerOptions": {
"target": "es5",
"module": "es2015",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es2015", "dom"],
"noImplicitAny": true,
"suppressImplicitAnyIndexErrors": true
},
"files": [
"src/main.ts"
],
"angularCompilerOptions": {
"genDir": "aot",
"skipMetadataEmit" : true
},
"exclude": [
"node_modules",
"bower_components",
"typings/main",
"typings/main.d.ts"
]
}
与tsc和tsconfig-compile-aot.json一起编译Main-aot.ts文件,再次为ES2015模块并生成您的JS文件。在编译时,我得到了我的JS文件我执行了命令
tsc src/main.ts
crolup-config.js
import rollup from 'rollup'
import nodeResolve from 'rollup-plugin-node-resolve'
import commonjs from 'rollup-plugin-commonjs';
import uglify from 'rollup-plugin-uglify'
export default {
entry: 'src/main.js',
dest: 'bundle.js', // output a single application bundle
sourceMap: false,
format: 'iife',
onwarn: function(warning) {
// Skip certain warnings
// should intercept ... but doesn't in some rollup versions
if ( warning.code === 'THIS_IS_UNDEFINED' ) { return; }
// console.warn everything else
console.warn( warning.message );
},
plugins: [
nodeResolve({jsnext: true, module: true}),
commonjs({
include: 'node_modules/rxjs/**',
}),
uglify()
]
}
我执行后,以下命令node_modules/.bin/crolup -c rolup -config.js
然后在执行NPM运行时,我会得到错误。
您需要在主页中添加以下代码:
window.module = {
id: 'foo',
exports: []
}
如果您导入具有.js
以外的扩展名的文件,则可以获得"未定义"错误。看起来您可能有.ts
文件,因此您需要配置commonjs
插件以查找.ts
扩展。
lollup commonjs插件默认情况下仅搜索具有.js
文件扩展名的文件。起初并不明显,但他们在文档中提到了这一点:
// search for files other than .js files (must already
// be transpiled by a previous plugin!)
extensions: [ '.js', '.coffee' ], // Default: [ '.js' ]
如果您将文件导入其他扩展名,则需要在此配置中列出它们。
