You can't directly. But you can do something like this :

plain.ejs

<script>
var state = {{ state }};
</script>
<script src ="/main.js"></script>

then in main.js

console.log(state);

Possibly dirty solution but you could create the state variable in global scope and main.js will be able to access it:

<script type='text/javascript'>
    var state = '<%= state%>'
</script>

<script src ="/main.js"></script>

If you have more data to be passed to the client you could pass it as an object:

res.render('plain',{data: {state:'admin', page_title: 'first page'}})

And then just output the whole object like this:

<script type='text/javascript'>
    var data = <%= JSON.stringify(data)%>
</script>

This way you could access the state as by data.state.
