How to apply custom theme in material ui - reactjs

Question

I am trying to apply a custom theme to my React component after reading this tutorial
http://www.material-ui.com/#/customization/themes
I wrote my theme in a separate javascript file like this
import Colors from 'material-ui/lib/styles/colors';
import ColorManipulator from 'material-ui/lib/utils/color-manipulator';
import Spacing from 'material-ui/lib/styles/spacing';
import zIndex from 'material-ui/lib/styles/zIndex';
export default {
spacing: Spacing,
zIndex: zIndex,
fontFamily: 'Roboto, sans-serif',
palette: {
primary1Color: Colors.cyan500,
primary2Color: Colors.cyan700,
primary3Color: Colors.lightBlack,
accent1Color: Colors.pinkA200,
accent2Color: Colors.grey100,
accent3Color: Colors.grey500,
textColor: Colors.deepPurpleA700,
alternateTextColor: Colors.white,
canvasColor: Colors.white,
borderColor: Colors.grey300,
disabledColor: ColorManipulator.fade(Colors.darkBlack, 0.3),
pickerHeaderColor: Colors.cyan500,
}
};
I apply this theme to my component in the follow way
import React from 'react';
import mui from 'material-ui';
import injectTapEventPlugin from 'react-tap-event-plugin';
import ThemeManager from 'material-ui/lib/styles/theme-manager';
import Colors from 'material-ui/lib/styles/colors';
import MyTheme from './theme.js';
injectTapEventPlugin();
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
messages : [{id: 1, text: 'Hi'}, {id: 2, text: 'Hello'}]
};
}
getChildContext() {
return {
muiTheme: ThemeManager.getMuiTheme(MyTheme)
};
}
componentWillMount() {
let newMuiTheme = this.state.muiTheme;
this.setState({
muiTheme: newMuiTheme,
});
}
render() {
var messageNodes = this.state.messages.map((message) => {
return (<div key={message.id}>{message.text}</div>);
});
return (<div>{messageNodes}</div>);
}
}
App.childContextTypes = {
muiTheme: React.PropTypes.object
};
export default App;
According to my theme when my control renders it should have a "deepPurpleA700" color .... but my control text is always black. So my theme is not applied.

You should first import your color from 'material-ui/styles/colors'
and then use them in palette object like this :
import React, { Component } from 'react';
import {render} from 'react-dom';
import {indigo500, indigo700, redA200} from 'material-ui/styles/colors';
import getMuiTheme from 'material-ui/styles/getMuiTheme';
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider';
import injectTapEventPlugin from 'react-tap-event-plugin';
injectTapEventPlugin();
import Main from './Main';
const muiTheme = getMuiTheme({
palette: {
primary1Color: indigo500,
primary2Color: indigo700,
accent1Color: redA200,
pickerHeaderColor: indigo500,
},
});
class App extends Component {
render() {
return (
<div>
<MuiThemeProvider muiTheme={muiTheme}>
<Main />
</MuiThemeProvider>
</div>
);
}
}
render(<App/>, document.getElementById('app')); //you should be having a div with an id of app in your index.html file
and the Main.js file is
import React, { Component } from 'react';
import FloatingActionButton from 'material-ui/FloatingActionButton';
export default class Main extends Component {
render() {
return (
<div>
<AppBar title="Title"/>
<FloatingActionButton secondary={true} />
</div>
);
}
}

For me it worked with:
import React, {Component} from 'react';
import {createMuiTheme} from '#material-ui/core/styles';
import MuiThemeProvider from '#material-ui/core/styles/MuiThemeProvider';
const theme = createMuiTheme({
palette: {
primary: {
main: '#0b5994',
},
secondary: {
main: '#1d83c6',
},
},
});
class App extends Component {
render() {
return (
<div className="App">
<MuiThemeProvider theme={theme}>
/* content here! */
</MuiThemeProvider>
</div>
);
}
}
export default App;

I am pretty sure you need to have
static childContextTypes = {
muiTheme: React.PropTypes.object,
};
before your
getChildContext()
method. Once that is done you should be able to remove any theme related stuff from
componentWillMount()
Now, this won't work for base text. But I can confirm that the theme is being applied. I tested it by adding an appBar component and changing the color in your theme.js file. I also added a List with ListItems and that text style is what you are looking for.
Here is a link to the gist of your modified App.jsx file.
Also, as a side note in you server.js you have a small typo on line 5 you should have
new webpackDevServer(webpack(config), {
not
new WebpackDevServer(webpack(config), {
