The GrailReact based Isomorph apps framework

Isomorphic Javascript means you can run the same code on the server as the client

isomorphic webapps vs SPA?

• Performance

• Maintainability

• Testability

• SEO

existing isomorphic solutions

• Meteor.js

How the isomorphic app should look like?

Isomorphic rendering

Isomorphic renderingReact

converts the state into DOM

state virtualdom DOM

describe how your state is rendered declaratively and make your business logic manipulate state

client vs serverthe difference

• context

• resource caching

• for server, get is enough

what about modules?
