How do I insert a Django template variable into a React script?

Question

I am using Django Rest Framework with React.js. My page shows one user\'s profile, using an api like this:

http://localhost:8000/api/profile/[pk]

When you render the component, you should pass the pk as a prop.

<script>
React.render(React.createElement(Profile, {
    userId: "{{ userId }}", 
    urlPrefix: "/api/profile/" 
}), element);
</script>

A better alternative might be to just fetch the user, and then render the component. For example, with superagent:

superagent.get('/api/profile/{{ userId }}', function(res){
    React.render(React.createElement(Profile, 
        {user: res.body}
    ), element);
});

With browserify, you can either include data in a script tag, and use that in your code:

<script>var _appData = {userId: "{{ userId }}"};</script>

Or export modules using the -r flag (.require() in the api).

# sh
browserify -r react -r src/profile.js:profile.js

// js
b.require('react').require('src/profile.js', {expose: 'profile.js'});

And then use the modules in regular script tags

<script>
var React = require('react');
var Profile = require('profile.js');

React.render(React.createElement(Profile, {
    userId: "{{ userId }}", 
    urlPrefix: "/api/profile/" 
}), element);
</script>
