How to retrieve a string in ReactIntl 2.0 without using FormattedMessage

You can easily return string using intl object provided by react-intl.

this is how you use intl object inside react class in much more easier way.

note: Render Component (main component) should wrap with IntlProvider

class MySubComponent extends React.Component{
  {/*....*/}

  render(){
    return(
     <div>
        <input type="text" placeholder = {this.context.intl.formatMessage({id:"your_id", defaultMessage: "your default message"})}
     </div>

    )
  }
   }
MySubComponent.contextTypes ={
 intl:React.PropTypes.object.isRequired
}

By defining contextTypes it will enable you to use intl object which is a context type prop. See react context for more details.

There is a better to solve placeholder problem.

<FormattedMessage ...messages.placeholderIntlText>
  {
     (msg) =>  <input type="text" placeholder = {msg} />
  }
</FormattedMessage>

Ok, there is a work around for that. I can add ReactIntl as the context in the component like this:

contextTypes: {
    intl: React.PropTypes.object.isRequired,
},

Then when trying to retrieve the string of the message and use it, for example in a placeholder, I can do this.

<MyComponent ref="mycomponent" placeholder={this.context.intl.messages.placeholder}/>
