Can't use <Text/> node as translated string on object

[acangiani]

On the project I'm currently working we needed to support several languages so we ended upusing preact-helmet to inject the title and the corresponding metatags for each of the App views, but I'm unable to make it work with {{fields}} placeholders, so I created this sample project to demonstrate the issue.

How to install and run the sample project

• Clone the repository with git clone git@github.com:acangiani/preact-i18n-issue.git
• Install the dependencies: npm install
• Run the project npm run start

First view

This one works fine and correctly adds the title and the title metatag.

Doing curl http://localhost:3000/, this outputs the following html:

...
<title>Foo - Bar</title>
<meta name="title" content="Foo - Bar" data-preact-helmet="true">
...

Second view

On the other hand on this view I needed to use a {{field}} placeholder, so doing curl http://localhost:3000/test, this outputs the following html:

...
<title>test - Bar</title>
<meta name="title" content="[object Object]" data-preact-helmet="true">
...

Things I tried

1. Use @withText as decorator on the second view, but I cannot access the props.
2. Tried to use withText as a functional component wrapper so to obtain the translated text but I couldn't make it work.
3. Tried to render the component to a string like:

   render(<Text id="second.title" " fields={{ field: props.slug }}>default text</Text>)

   but I only obtained the default text regardless of the i18n definitions loaded on the IntlProvider.

Bottom line what I need it's to obtain the translated text as a string but I'm unable to do so, could you please help with this?

@acangiani Thanks for the report. withText is also capable of accepting a function which will receive props, and resolve <Text> components with fields. I gave your App a try and the following changes seemed to make the title render correctly:

@withText((props) => ({
  title: <Text id="second.title" fields={{ field: props.slug }} />
}))
export default class SecondView extends Component {
  render(props, state) {
    return (
      <div>
        <Helmet
          title={props.title}
          meta={[
            {name: "title", content: props.title },
          ]}
        />
      </div>
    );
  }
};

Let me know if that resolves the issue.
