问题
My app compiles with .ts, .js, and .jsx files and runs. Now I try changing a .jsx file to .tsx and it breaks.
How do I fix this compile error:
ts-loader: Using typescript@1.6.2 and C:\users\ruser\Desktop\Downloads\divinote\site\tsconfig.json 67% 226/234 build modulesModuleParseError: Module parse failed: C:\users\ruser\Desktop\Downloads\divinote\site\node_modules\ts-loader\index.js?cacheDirectory!C:\users\ruser\Desktop\Downloads\divinote\site\src\app\views\header\DiviAppBar.tsx
Line 15: Unexpected token <
You may need an appropriate loader to handle this file type.

when I compile this code:
"use strict";
import React = require('react');
import AppBar = require('material-ui/lib/app-bar');
class DiviAppBar extends React.Component
{
render()
{
return (
<AppBar />
);
}
}
export = DiviAppBar;
with this webpack config file:
'use strict';
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');

var path = require('path');
var rootPath = __dirname; //site

The first issue has to do with "jsx" config as mentioned by Martin. Set "jsx" to "react".
The second issue has to do with your code. Change it like this:
class DiviAppBar extends React.Component<Props, State> ...
Create an interface for your props and another one for your state. If you don't have any use empty objects.
class DiviAppBar extends React.Component<{}, {}> ...
