I think it uses https://lodash.com/docs#template

// using the "interpolate" delimiter to create a compiled template
var compiled = _.template('hello <%= user %>!');
compiled({ 'user': 'fred' });
// → 'hello fred!'

// using the HTML "escape" delimiter to escape data property values
var compiled = _.template('<b><%- value %></b>');
compiled({ 'value': '<script>' });
// → '<b>&lt;script&gt;</b>'

Well that's is strange then because in index.html it uses the <%= %> way of doing for all other variables.

oops, hadnt read carefully.

anyway the title bug was not related to the "typo" as it wasn't working anyway.

any idea why it is not showing up in the html generated by the server ?

I'm just calling:

this.context.onSetTitle('[blahblah title]');

in componentDidMount in a classe with the withContext decorator.

@vitaminwater componentDidMount() is never called on the server (during server-side rendering). You may want to use componentWillMount() instead for that purpose.

Still not working:(

can you paste your class here?

After deploying on my server, it works.

I'm building on this server with npm run build -- release and run with forever restart build/server.js

So looks like the bug is only when running with npm start

I have the same issue, but with the call to this.context.onSetTitle( this.props.title ) in render(). The title reads 'undefined' but I've specified a title in the jade template.

@vitaminwater : can you please share how you called the method in your component? I tried the run build and forever combination that you mentioned but without success ...
