webpack-dev-server node.js api hot module reload not working

[tulika21-zz]

Trying to configure HMR through the node.js api as given here https://webpack.github.io/docs/webpack-dev-server.html#hot-module-replacement-with-node-js-api gives an error. HMR through CLI is working fine.

This is the error:
Module parse failed: /u/saxenat/react-blueprint/src/js/app.js Unexpected token (5:16) You may need an appropriate loader to handle this file type. SyntaxError: Unexpected token (5:16) at Parser.pp.raise (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:923:13) at Parser.pp.unexpected (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:1490:8) at Parser.pp.parseExprAtom (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:333:12) at Parser.pp.parseExprSubscripts (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:228:19) at Parser.pp.parseMaybeUnary (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:207:17) at Parser.pp.parseExprOps (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:154:19) at Parser.pp.parseMaybeConditional (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:136:19) at Parser.pp.parseMaybeAssign (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:112:19) at Parser.pp.parseExprList (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:660:23) at Parser.pp.parseSubscripts (/u/saxenat/react-blueprint/node_modules/webpack/node_modules/acorn/dist/acorn.js:252:29)

The app.js file is:
`import React from 'react';
import ReactDOM from 'react-dom';
import Hello from '../components/SayHelloComponent/SayHello.jsx';

ReactDOM.render(, document.getElementById('app'));`

Did you add webpack/hot/dev-server to your entry point (see docs)?

If yes, please show your webpack config file, preferably with unnecessary things stripped out.
