I have the following imports in my index.js
file
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import 'core-js/fn/promise';
my webpack is set up as
var HTMLWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
template: __dirname + '/app/index.html',
filename: 'index.html',
inject: 'body'
});
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const extractSass = new ExtractTextPlugin({
filename: "[name].[contenthash].css",
disable: process.env.NODE_ENV === "development"
});
module.exports = {
entry : __dirname + '/app/index.js',
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
} ,
{
test: /\.scss$/,
use: [{
loader: "style-loader"
}, {
loader: "css-loader"
}, {
loader: "sass-loader",
}]
}
],
},
output: {
filename: 'transformed.js',
path: __dirname + '/docs'
},
plugins: [
HTMLWebpackPluginConfig,
extractSass,
new ExtractTextPlugin("styles.css")
]
}
i have updated my webpack
and babelrc
to the following and it is working now.
.babelrc
{
"presets": [
'es2015', "react",
]
}
webpack.config.js
module.exports = {
entry : [__dirname + '/app/index.js'],
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
} ,
{
test: /\.scss$/,
use: [{
loader: "style-loader"
}, {
loader: "css-loader"
}, {
loader: "sass-loader",
}]
}
],
},
output: {
filename: 'bundle.js',
path: __dirname + '/docs'
}
}
Had the same issue and wanted to avoid npm run eject
, so I included this script in index.html while in development mode:
<script src="//cdn.polyfill.io/v2/polyfill.min.js"></script>
It worked for me with npx create-react-app my-app
version 1 in React v16.6.3
I needed to also test production but 127.0.0.1 didn't work for me either, so I used netlify with command netlify deploy
and it worked.
