rendora - dynamic server-side rendering using headless Chrome to effortlessly solve the SEO problem for modern javascript websites

  •    Go

Rendora can be seen as a reverse HTTP proxy server sitting between your backend server (e.g. Node.js/Express.js, Python/Django, etc...) and potentially your frontend proxy server (e.g. nginx, traefik, apache, etc...) or even directly to the outside world that does actually nothing but transporting requests and responses as they are except when it detects whitelisted requests according to the config. In that case, Rendora instructs a headless Chrome instance to request and render the corresponding page and then return the server-side rendered page back to the client (i.e. the frontend proxy server or the outside world). This simple functionality makes Rendora a powerful dynamic renderer without actually changing anything in both frontend and backend code. Dynamic rendering means that the server provides server-side rendered HTML to web crawlers such as GoogleBot and BingBot and at the same time provides the typical initial HTML to normal users in order to be rendered at the client side. Dynamic rendering is meant to improve SEO for websites written in modern javascript frameworks like React, Vue, Angular, etc...

  •    Javascript

Dynamic Rendering is, as the name implies, about rendering a page based on a dynamic condition. What we want to do is solve the very common problem of modern Progressive Web Apps not working very well with some older crawlers that are unfortunately still in use across the web, such as on those used by Facebook and LinkedIn. Our condition is therefore ”if a crawler or bot sees the page, give it prerendered markup”. Even Google thinks this is a pretty good approach for SEO.
