PhearJS (http://phear.io) is a prerender for client-side dynamic web pages. To serve prendered versions of your website to bots like the ones from Yahoo, Bing, Yandex, Google and so forth you can use this Express middleware. When a bot is detected the middleware will serve a prerendered version of your page.
You should have a PhearJS instance running somewhere. For setup instructions please refer to these installation instructions.
If you have that running, install phearjs-express middleware:
npm install phearjs-express
Add the following code to your Express app and every request will automatically be served prerendered only if necessary.
var prerender = require('phearjs-express');
app.use(prerender({}));
var prerender = require('phearjs-express');
app.use(prerender({phear_url: http://192.168.1.42:1337}));
var prerender = require('phearjs-express');
app.use(prerender({phear_agent: 'MyVerySpecialPhearJSBot/0.1.2'}));
If something doesn't work as expected or breaks, please create an issue. When you feel like fixing an issue or improving this middleware, feel free to open an issue and create a pull request!
I've used the JSCS linter, so for bonus points, lint :)
