angular - Webpack 2 won't work when using ts-loader -


i have been setting basic angular 2 (typescript) application, uses webpack 2 bundling etc.

my issue when use ts-loader process typescript (.ts) files lot of errors. suspect, not totally sure, errors ts-loader not excluding node_modules directory though specify exclude in webpack config.

i want able setup webpack config (and app) typescript can transpiled , app can correctly bundled webpack. please help.

webpack.config.js

var webpack = require('webpack');  module.exports = {     entry: './src/main.ts',     output: {     filename: './dist/bundle.js', }, resolve: {     // add `.ts` , `.tsx` resolvable extension.     extensions: ['.ts', '.tsx', '.js'] // note if using webpack 1 you'd need '' in array }, module: {     loaders: [{         test: /\.tsx?$/,         exclude: /node_modules/,         loader: 'ts-loader'     }] }, plugins: [     new webpack.contextreplacementplugin(         /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,     __dirname ), ] };

package.json

{   "name": "tiptip-webpack",   "version": "1.0.0",   "description": "",   "main": "webpack.config.js",   "scripts": {     "dev": "webpack -d --watch"   },   "keywords": [],   "author": "",   "license": "isc",   "dependencies": {     "@angular/common": "2.4.6",     "@angular/compiler": "2.4.6",     "@angular/core": "2.4.6",     "@angular/forms": "2.4.6",     "@angular/http": "2.4.6",     "@angular/platform-browser": "2.4.6",     "@angular/platform-browser-dynamic": "2.4.6",     "@angular/platform-server": "2.4.6",     "@angular/router": "3.4.6",     "@angularclass/conventions-loader": "^1.0.2",     "@angularclass/hmr": "~1.2.2",     "@angularclass/hmr-loader": "~3.0.2",     "core-js": "^2.4.1",     "http-server": "^0.9.0",     "ie-shim": "^0.1.0",     "jasmine-core": "^2.5.2",     "reflect-metadata": "^0.1.9",     "rxjs": "5.0.2",     "zone.js": "0.7.6"   },   "devdependencies": {     "source-map-loader": "^0.2.0",     "ts-loader": "^2.0.3",     "typescript": "^2.2.0",     "typings": "^2.1.0",     "webpack": "^2.2.0"   } }

error messages after running 'npm run build' enter image description here

this not webpack problem typescript problem. webpack correctly ignores node_modules typescript complains because doesn't know types map or set. these es6 features , if set target in compileroptions es5 won't include these in compilation , therefore doesn't know types. compiler options documentation:

note: if --lib not specified default library injected. default library injected is:
► --target es5: dom,es5,scripthost
► --target es6: dom,es6,dom.iterable,scripthost

you can set lib option use es6 (or higher version e.g. es2017):

"lib": ["es6", "dom"]
