Unexpected token with react jsx and babel
I was trying to get started with react. I installed npm, browserify, babel and its presets. Babel not able to transform JSX code. Can anyone help me understand what is happening. Am i using the correct presets for babel ? My demo.js
"use strict";
var React = require('react');
var ReactDOM = require('react-dom');
var Test = React.createClass({
render: function(){
var {a, b, ...other} = this.props;
return(
<div>Hi</div>
);
}
});
This is the command i run to create bundle.
sudo browserify -t [ babelify --presets [ es2015 react ] ] src/demo.js -o ./bundle/app.js
Following is the error i get
SyntaxError: /Users/shashank/git_views/srh_labs/webui/src/demo.js: Unexpected token (8:13)

7 | render: function(){

$ sudo browserify -t [ babelify --presets [ es2015 react ] ] src/demo.js -o ../server/rest/src/main/webapp/uiserver/bundle/app.js
The object rest/spread operator (used on line 8) is not part of the es2015
package. You have to install the transform-object-rest-spread plugin to transform that.
尝试创建一个.babelrc文件并将其放入:
{
"presets": ["react"]
}
