![]() om_jsonapi.require(:photo).permit(photographer: ) Considering a sample params call in a controller: It is mostly just a translator, that transforms standard compliant input to what Rails (and Rails developers) expect. Our gem aims to support Rails developers in consuming JSON:API input. That is why we brought a new library to life. Returning data in this format was easy, as you had ActiveModelSerializers or fast_jsonapi from Netflix, but there was no way to easily understand the input client would send us.\īut since we already could compare the JSON:API compliant input and the Rails expected one, why not get the best out of two worlds? Why should not we let Rails developers keep using their parameters as they always had done, while allowing JSON:API consumers to actually consume and feed the server with JSON:API data? JsonApi::Parameters JSON:API gave us a good, unified solution that had every scenario that we needed. However, JSON:API provides lots of great functionalities and features that would not be so easy to achieve on your own (and then, you would have to educate your consumers on how to use these).Īt Visuality the choice was made that JSON:API is the way we want to go for now - as it was either that, or the implemented-here solutions that varied in features between different projects. Take a look at a sample:įor a person that had been working with Rails over the years, but not with JSON:API, I would not be surprised if you were in favour of the latter example. ![]() The input that JSON:API specification describes is pretty simple. It would be the best if it did not require huge configuration overhead and if it didn't force people to learn and write code in a very different (compared to what is acknowledged as standard, Rails-way) convention. We had a simple goal: our Rails application must read JSON:API compliant input and handle it. It lead us to a point where we decided that maybe it is a good idea to create something of our own. The ones that supposedly were to support input deserialisation either did not work 100%, were abandonware or weren't supporting JSON:API specification in its entirety. The major shortcoming was that there was no go-to solution for receiving and understanding the input the consumer sends to our application. There are many implementations of this standard (you can find a comprehensive list here), but what we recognised is that most of them usually work one-way: to serialise the data we have in the Rails application so it can be served to the API consumer. Let's get down to business now, and as a backend engineer at Visuality, I will be your guide today! Shortcoming If you would like to learn more about JSON:API consider checking out Nadia's article about JSON:API and NIH syndrome. Over time we researched and developed ways to introduce JSON:API into our Rails applications, so that we could be compliant with this specification, thanks to which the development process would be more effective and time efficient. One of the many things we learned at Visuality is that its not only okay to try new things, but it is also even better if other people tried these and have some insights on how to actually do it the good way. Consumption of different interfaces brings the experience, and experience brings knowledge. ![]() Let’s go ahead and test this test_throttle.sh.In the world of modern web applications you cannot avoid becoming a heavy user of APIs. throttled_response = -> ( env ), :status => 429 return end REDIS. ip end # Send the following response to throttled clients self. ip end # Allow an IP address to make 5 requests every 5 seconds throttle ( 'req/ip', limit: 5, period: 5 ) do | req| new # Allow all local traffic whitelist ( 'allow-localhost' ) do | req| store = ActiveSupport:: Cache:: MemoryStore. Now we generate new Rails API application by passing the -api directive to the rails new command:Ĭlass Rack:: Attack # `Rack::Attack` is configured to use the `Rails.cache` value by default, # but you can override that by setting the `Rack::` value Rack:: Attack. This how-to guide aims to help you get started the right way using Rails 5 to build the perfect API, and it comprises of the following sections:įirst, make sure you are running Ruby 2.2.2+ or newer as it’s required by Rails 5. Until now, arguably the best option for creating APIs in Ruby has been Grape, and while Grape is still a brilliant option (especially if you like to DIY), there are some great advantages to using Rails 5 in API mode, such as ActiveRecord by default, a strong developer community, and having the asset pipeline and front end features available should you need them as your project evolves. ![]() Thanks to the new rails-api gem that ships as part of the Rails 5 core, Rails is now an ideal candidate for building streamlined APIs quickly and easily.
