I am trying to make a web app using ExpressJS and Coffeescript that pulls data from Amazon, LastFM, and Bing’s web API’s.
Users can request data such as the prices for a specific album from a specific band, upcoming concert times and locations for a band, etc… stuff like that.
My question is: should I make these API calls client-side using jQuery and getJSON or should they be server-side? I’ve done client-side requests; how would I even make an API call from the server side?
I just want to know what the best practice is, and also if someone could point me in the right direction for making server-side API requests, that would be very helpful.
Thanks!
It’s often good to abstract away your storage and dependent services to isolate changes and offer a consolidated and consistent web api for your application. But sometimes, if you have a good hypermedia web api (RESTful responses link to other resources), you could reference a resource link from another service in the response from your service (ex: SO request could reference gravatar image/resource of user). There’s no one size fits all – it depends on whether you want to encapsulate the dependency or integrate with it.
It might be beneficial to make the web-api requests from your service exposed via expressjs as your own web-apis.
Making http web-api requests is easy from node. Here’s another SO post covering that:
