I'm trying to make an aot build with webpack 3 and angular 5, but there are so many tutorials on the net and none show complete example without questions, so far I've got the following configuration: (For those who have questions about paths - I use it in the java app)
webpack.config.aot.js:
const webpack = require("webpack");
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const ngToolsWebpack = require('@ngtools/webpack');
module.exports = {
context: __dirname + "/src/main/webapp/resources/script/",
entry: {
app: "./core/main.aot.ts",
vendor: "./vendor.ts",
polyfills: "./polyfills.ts"
},
output: {
filename: 'js/[name].js',
chunkFilename: "js/chunks/[id].chunk.js",
publicPath: "resources/compiled/",
path: __dirname + '/src/main/webapp/resources/compiled'
},
resolve: {
alias: {
STYLES: __dirname + "/src/main/webapp/resources/css/",
SCRIPT: __dirname + "/src/main/webapp/script/"
},
extensions: [".js", ".json", ".scss", ".ts"]
},
module: {
rules: [
{
test: /[\/]angular\.js$/,
loader: 'exports-loader?angular'
},
{
test: /\.html$/,
loader: 'raw-loader'
},
{
test: /(?:\.ngfactory\.js|\.ngstyle\.js|\.ts)$/,
loader: '@ngtools/webpack'
}
]
},
plugins: [
new ngToolsWebpack.AngularCompilerPlugin({
tsConfigPath: './tsconfig.aot.json',
entryModule: './src/main/webapp/resources/script/core/i18n/app.module.en#AppModule'
})
]
};
tsconfig.aot.json:
{
"compilerOptions": {
"module": "es2015",
"moduleResolution": "node",
"target": "es5",
"noImplicitAny": false,
"sourceMap": true,
"mapRoot": "",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": [
"es2015",
"dom"
],
"outDir": "lib",
"skipLibCheck": true,
"rootDir": "."
},
"exclude": [
"node_modules/*",
"target/*"
],
"angularCompilerOptions": {
"genDir": "./src/main/webapp/resources/script/factory",
"rootDir": ".",
"baseUrl": "/"
}
}
main.aot.ts:
import {platformBrowser} from '@angular/platform-browser';
import {enableProdMode} from "@angular/core";
import {AppModuleNgFactory} from '../factory/app/app.module.ngfactory';
enableProdMode();
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);
File structure(simplified):
- webpack.config.aot.js
- tsconfig.aot.js
- src/
- main/
- webapp/
- resources/
- script/
- vendor.ts
- polyfills.ts
- core/
- main.aot.ts
- i18n/
- app.module.en.ts
(Please let me know if I haven't showed something relevant)
So when I'm tring to build it using webpack -p --config ./webpack.config.aot.js
I get following error:
ERROR in src/main/webapp/resources/script/core/main.aot.ts(5,34): error TS2307: Cannot find module '../factory/app/app.module.ngfactory'.
Which sound pretty legitimate as there is no AppModuleNgFactory there, but as i looked in tutorials it is supposed to be generated upon aot build, using genDir, am I right? (please not that if i omit app/ folder, so path looks '../factory/app.module.ngfactory' i get the same error)
Is it right to point at the non-existing AppModuleNgFactory on the aot build with @ngtools/webpack?
What is that AppModuleNgFactory? There is little to no documentation about anythig of it on the angular site
What should I change in my config to successfully generate aot build?
If I change main file to bootstrap AppModule itself, it builds successfully, but in browser i get NullInjectorError: No provider for t!
error
Without minification it shows: No provider for CompilerFactory!
It appears that @ngtools/webpack could handle bootstraping module factory itself from original main file, eg webpack entry should be : path_to_file/main.ts
and main.ts contains:
platformBrowserDynamic().bootstrapModule(AppModule);
And whole thing will be handled itself, no additional configs!
It is really amazing
I do not think the accepted answer is correct. I had the same problem and there were two reasons for my problem:
I had to include the module in my includes in tsconfig
:
"include": [
"ng/src/main/app.module.ts",
"ng/src/main.aot.ts"
]
My include in main.aot.ts
just referenced the source file but with ngfactory
suffix:
import { MainModuleNgFactory } from './main/app.module.ngfactory';
