typescript - webpack TS2304 Cannot find name 'Map', 'Set', 'Promise'

Question

I have the following webpack.config.js

var path = require("path");
var webpack = require('webpack');

module.exports = {
  entry: {
    'ng2-auto-complete': path.join(__dirname, 'src', 'index.ts')
  },
  resolve: {
    extensions: ['', '.ts', '.js', '.json', '.css', '.html']
  },
  output: {
    path: path.join(__dirname, 'dist'),
    filename: "[name].umd.js",
    library: ["[name]"],
    libraryTarget: "umd"
  },
  externals: [
    /^rxjs//,    //.... any other way? rx.umd.min.js does work?
    /^@angular//
  ],
  devtool: 'source-map',
  module: {
    loaders: [
      { // Support for .ts files.
        test: /.ts$/,
        loaders: ['ts', 'angular2-template-loader'],
        exclude: [/test/, /node_modules/(?!(ng2-.+))/]
      }
    ]
  }
};

and the following tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "noEmitHelpers": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "sourceMap": true,
    "pretty": true,
    "allowUnreachableCode": true,
    "allowUnusedLabels": true,
    "noImplicitAny": false,
    "noImplicitReturns": false,
    "noImplicitUseStrict": false,
    "noFallthroughCasesInSwitch": false,
    "allowSyntheticDefaultImports": true,
    "suppressExcessPropertyErrors": true,
    "suppressImplicitAnyIndexErrors": true,
    "outDir": "dist",
    "baseUrl": "src"
  },
  "files": [
    "src/index.ts"
  ],
  "exclude": [
    "node_modules"
  ],
  "compileOnSave": false,
  "buildOnSave": false
}

When I run tsc command as the following, it all works fine.

ng2-auto-complete (master)$ tsc --declaration
ng2-auto-complete (master)$ 

When I run webpack command, it shows typescript compile errors.

ng2-auto-complete (master)$ webpack

I don't know what I am missing for webpack and typescript compilation.

node_modules has been excluded in tsconfig.json

"exclude": [ "node_modules" ],

and type definitions are there in node_modules

  "devDependencies": {
    "@types/core-js": "^0.9.32",
    "@types/node": "^6.0.31"

I also tried to use typings.json and typings directory without success.

{
  "globalDependencies": {
    "core-js": "registry:dt/core-js#0.0.0+20160725163759",
    "jasmine": "registry:dt/jasmine#2.2.0+20160621224255",
    "node": "registry:dt/node#6.0.0+20160815222444"
  }
}

FYI, versions

$ node --version
v5.7.1
$ npm --version
3.6.0
$ tsc --version
Version 2.0.0

How do I get rid of TS2304 errors with webpack command?

Answer 1

I added this to work in tsconfig.json, and it seems working without any error.

  "compilerOptions": {
    "target": "es5",
    "lib": ["es5", "es6", "dom"],  <--- this
    ...
  }

I am not sure lib are for Typescript 2.0 function or not, but found out there are several libraries are available

From the typescript config schema (note the es2015.collection)

 "lib": {
      "description": "Specify library file to be included in the compilation. Requires TypeScript version 2.0 or later.",
      "type": "array",
      "items": {
        "type": "string",
        "enum": [ "es5", "es6", "es2015", "es7", "es2016", "es2017", "dom", "webworker", "scripthost", "es2015.core", "es2015.collection", "es2015.generator", "es2015.iterable",
                    "es2015.promise", "es2015.proxy", "es2015.reflect", "es2015.symbol", "es2015.symbol.wellknown", "es2016.array.include", "es2017.object", "es2017.sharedmemory" ]
      }
    }

This solves the compile errors, but I still wonder why tsc command works without any errors, but webpack does not. tsc searches for all possible libraries without using lib by tsconfig.json?
