If some more details needed please let me know.
Please suggest, what do i need to do.... Thanks
My webpack.js file is as....
const path = require('path');
const HtmlWebPackPlugin = require('html-webpack-plugin');
const {
CheckerPlugin,
TsConfigPathsPlugin,
} = require('awesome-typescript-loader');
const DuplicatePackageCheckerPlugin = require('duplicate-package-checker-webpack-plugin');
const ROOT = path.resolve(__dirname, '..');
module.exports = {
module: {
rules: [
{
test: /.tsx?$/,
use: 'awesome-typescript-loader',
exclude: /node_modules/,
},
{
test: /.(png|jpg|gif|svg)$/,
use: [
{
loader: 'url-loader',
options: {
limit: 25000,
},
},
],
},
{
test: /.html$/,
use: 'html-loader',
},
],
},
resolve: {
extensions: ['.tsx', '.ts', '.js'],
modules: [path.resolve(ROOT, 'shared'), 'node_modules'],
plugins: [new TsConfigPathsPlugin()],
},
plugins: [
new HtmlWebPackPlugin({
template: path.join(ROOT, 'shared', 'index.html'),
filename: './index.html',
}),
new CheckerPlugin(),
new DuplicatePackageCheckerPlugin(),
],
};
I think babel-loader will work but can't find any way to use babel-loader. I need this app to run on ie11 and safari as well.
Please suggest some solution...

Answer 1

The issue is that by default the application was being rendered on IE7, that is - not on IE11/Edge that supports the transpiled build. So I had to mention the meta information to let the browser know that the intended browser is IE11/Edge. Add this to the head section of your index.html:
<meta http-equiv="X-UA-Compatible" content="IE=edge">
Now you might be getting some errors in the console that read SCRIPT5009: 'Set' is undefined - refer to the below link relating to polyfills for the Set collection type:
React JavaScript Environment Requirements
For more information on the issue see:
React app not rendering in IE11 and below

Answer 2

Because you are opening it in Microsoft edge, try opening it in latest chrome version... problem will be solved.....this works for ReactJs projects
