Why does webpack add; to json and can't parse it?

Question

JavaScript

I'm trying to add json to a component.

import React, { Component } from 'react';
import { connect } from 'react-redux';
import { setProducts } from './actions/products';
import axios from 'axios';
import products from './products.json';

class App extends Component {
  componentWillMount() {
    const { setProducts } = this.props;
    const response = axios.get('products.json');

    setProducts(response.data);
  }

  render() {
    //const { products } = this.props;
    return (
      <ul>
        {!products
          ? 'Загрузка...'
          : products.map(product => {
              <li key={product.id}>
                <b>{product.title}</b> - {product.author}
              </li>;
            })}
      </ul>
    );
  }
}

const mapStateToProps = ({ products: { products } }) => ({
  products
});

const mapDispatchToProps = dispatch => ({
  setProducts: products => dispatch(setProducts(products))
});

export default connect(
  mapStateToProps,
  mapDispatchToProps
)(App);

As a result, the following error occurs:

ERROR in ./src/products.json
Module parse failed: Unexpected token ; in JSON at position 4604 while parsing near '...99,
  "rating": 5
}];'
You may need an appropriate loader to handle this file type.

Answer 1

I found an error, it turns out that webpack-dev-server was looking for files in the root of the project, and they were in / src, it was enough to specify the path to it in the webpack config

devServer: {
    contentBase: path.join(__dirname, '/src')
  },

Answer 2

What version of webpack?
Try
{
test: /\.json$/, exclude
: /(node_modules)/,
loader: "json-loader"
}
