问题
I'm struggling to add <Link/> component to my material-ui AppBar
This is my navigation class:
class Navigation extends Component {
constructor(props) {
super(props)
}
render() {
var styles = {
appBar: {
flexWrap: 'wrap'
},
tabs: {
width: '100%'
}
}
return (
<AppBar showMenuIconButton={false} style={styles.appBar}>
<Tabs style={styles.tabs}>
<Tab label='Most popular ideas'/>
<Tab label='Latest ideas' />
<Tab label='My ideas' />
</Tabs>
</AppBar>
)
}
}
Which looks okay:
Tabs are clickable, have fluid animations, that's cool. But how do I wire them up together with react-router and its' <Link/> component?
I've tried adding onChange listener like that:
<Tab
label='My ideas'
onChange={<Link to='/myPath'></Link>}
/>
However I'm getting following error:
Uncaught Invariant Violation: Expected onChange listener to be a function, instead got type object
If I try to wrap <Tab/> component into <Link/> component, I'm getting error that <Tabs/> component accepts only <Tab/> component.
This doesn't work either (no error is being produced, but clicking on Tab does not bring me to the path):
<Tab label='Most popular ideas'>
<Link to='/popular'/>
</Tab>
How do I make <Link/> component work together with <Tabs> and <AppBar>? If that's not possible, I can use any other component from material-ui library to form a proper menu.

For Material UI 1.0 with Typescript: see this post by @ogglas below.
For Material-UI 1.0 with plain JS:
<Tabs value={value} onChange={this.handleChange}>
{
this.props.tabs.map(
({label, path})=><Tab key={label}
label={label}
className={classes.tabLink}
component={Link}
to={path} />
)
}
</Tabs>
And classes.tabLink is defined as:
tabLink : {
display:"flex",
alignItems:"center",
justifyContent:"center"
}
How this works?
All the mui 1.0 components inheriting from ButtonBase, support a component prop, see ButtonBase. The idea is to allow you to control what the component renders as its wrapper/root element. Tab also has this feature although at the time of writing this answer this prop is not documented explicitly, but as Tab inherits from ButtonBase, all its props carry over (and the documentation does cover this).
Another feature of ButtonBase is that all the extra props, not in use by ButtonBase or inherited component, are spread over the specified component. We have used this behavior to send the to prop used by Link by giving it to Tab control. You can send any additional props in the same way. Note that this is documented explicitly for both ButtonBase and Tab.
Thanks @josh-l for asking this to be added.

here's how you can do it now:
<Tabs onChange={this.changeTab} value={value}>
<Tab value={0} label="first" containerElement={<Link to="/first"/>} />
<Tab value={1} label="second" containerElement={<Link to="/second"/>}/>
<Tab value={2} label="third" containerElement={<Link to="/third"/>} />
</Tabs>

Since we are using TypeScript I could not use @hazardous solutions. This is how we implemented routing for material-ui v1.0.0-beta.16 and react-router 4.2.0. The reason why we are splitting this.props.history.location.pathname is because we need to access /renewals/123 for example. If we did not do this we would get the following warning and no tab would be displayed as active: Warning: Material-UI: the value provided '/renewals/123' is invalid

You can try this simple method
<Tab label='Most popular ideas' to='/myPath' component={Link} />

So my work-around for this solution has been quite reliable, though it may be more manual of a solution than what you're looking to do.
The strategy that I've been using is to actually not even use the Link Component. Instead, you'll utilize the Tabs onChange property as a callback that can respond to Tab clicks, and track location manually with Props on the Parent.
You can import a utility called History from react-router that will allow you to manually push locations. While using React-Router, your component tree will have access to Location prop that has a pathname key with the string of your current location.
We will manually parse this string into the components that make up your current URL, then use a Switch statement to decide both which tab is currently selected and also where to link to when a tab is clicked. (This gives you a fair amount of control over navigation)
( e.g. ['', 'latest'] )
Here is a mock up of what your component MAY look like after integrating this solution.
import React from 'react';
import {History} from 'react-router';
function parseLocation(location) {
if (String(location)) {
var locationArray = location.split('/');
return locationArray;
} else {
return false;
}
};
function filterPath(path) {
let locationArray = parseLocation(path);
return locationArray[locationArray.length - 1];
};
var Navigation = React.createClass({
mixins: [History],
getPage() {
if (this.props.location.pathname) {
let pathname = this.props.location.pathname;
let pageName = filterPath(pathname);
return pageName;
} else {
return false;
}
},
decideContent() {
let page = this.getPage();
let content;
switch(page) {
case 'popular':
content = 0;
case 'latest':
content = 1;
case 'myideas':
content = 2;
default:
content = 0;
}
return content;
},
handleTabChange(value) {
let location = false;
switch (value) {
case 0:
location = 'popular';
break;
case 1:
location = 'latest';
break;
case 2:
location = 'myideas';
break;
}
if (location && location !== this.getPage()) {
this.history.pushState(null, '/'+location);
}
},
render() {
var styles = {
appBar: {
flexWrap: 'wrap'
},
tabs: {
width: '100%'
}
};
let content = this.decideContent();
let tabs = <Tabs
onChange={this.handleTabChange}
value={content}
>
<Tab label="Most Popular Ideas" value={0} />
<Tab label="Latest Ideas" value={1} />
<Tab label="My Ideas" value={2} />
</Tabs>;
return (
<AppBar showMenuIconButton={false} style={styles.appBar}>
{tabs}
</AppBar>
);
}
});

TypeScript implementation of the router-driven tabs.
For those who look for the TypeScript implementation. Easy configurable. Driven by tabs configuration.
interface ITabsPageProps {
match: match<{page: string}>;
history: History;
}
const tabs = [{
label: 'Fist Tab',
link: 'fist-tab',
component: <FirstTabContent/>
}, {
label: 'Second Tab',
link: 'second-tab',
component: <SecondTabContent/>
}, {
label: 'Third Tab',
link: 'third-tab',
component: <ThirdTabContent/>
}];
export class TabsPage extends React.Component<ITabsPageProps> {
handleChange(tabLink: string) {
this.props.history.push(`/tabs-page/${tabLink}`);
}
render() {
const currentTab = this.props.match.params.page;
const selectedTab = tabs.find(tab => currentTab === tab.link);
return (
<Fragment>
<Tabs
value={currentTab}
onChange={(event, value) => this.handleChange(value)}
>
{tabs.map(tab => (
<Tab
key={tab.link}
value={tab.link}
label={tab.label}
/>
))}
</Tabs>
{selectedTab && selectedTab.component}
</Fragment>
);
}
}

This is solved using the <Link /> from material-ui instead of directly using the <Link /> or <NavLink /> from react-router. The example for the same can be found in the documentation here.
https://material-ui.com/components/links/
Also <Button /> tag has a component prop to achieve this
<Button color="inherit" component={Link} to={"/logout"}>Logout</Button>
An extensive discussion on this can be found here
https://github.com/mui-org/material-ui/issues/850
