REST APIs – Efficiently create and document with Neutrinos


Neutrinos - June 1, 2020 - 0 comments

REST API is considered as the standard protocol for web APIs. It is the most logical, efficient and widespread standard in the creation of APIs for Internet services. 

 It creates an interface between systems using HTTP to obtain data and generate operations on those data in all possible formats, such as XML and JSON.

The reasons why REST API is mostly used is because:

  • It is user-friendly and it is easy to understand for the developers to code on it.
  • It provides a great deal of flexibility as data is not tied to resources or methods
  • It can handle multiple types of calls, return different data formats, and even change structurally with the correct implementation

When you are creating apps on Neutrinos Platform, you can seamlessly consume and expose REST APIs. You can:

  • Design these APIs using flow-based modelling. That is, you can drag and drop nodes to create logical server flows to create the API and perform any operation
  • You can configure how the API should behave using a UI editor
  • You can create swagger documents on the go when you create the APIs 
  • You can also preview the server app before deploying it 

Now, how do we achieve all this? let’s dig deep for more understanding.

Creating REST APIs

On Neutrinos Studio, you can expose any part of the application logic as an API or a microservice. This is achieved by creating server flows by using a wide range of default nodes that the Studio provides to you.

For example, let us consider this server flow:

Using the HTTP IN node, we are creating a REST API endpoint called createuser and by choosing the POST method, we are sending new data to the server.

The UI Editor to configure the node

Similarly, you can create multiple REST APIs for your app depending on your app requirement.

When you deploy the application, the REST API end-points that you have defined in the Server flows will get created, and will be ready to be consumed by anyone. There is no need for extra configurations or deployments.

Documenting REST APIs

When exposing REST APIs, you can also create the documentation of the API on the go. Neutrinos generates the swagger documentation according to the Open API spec and makes it available under the API end-point.

For example, here is how you can document the REST API using the UI editor when you are creating the createuser REST API endpoint:

When the app is deployed, the server flows that you have designed as part of your app are also deployed, and the swagger documentation for these APIs are created. 

Previewing REST APIs

Before you deploy the app, you can test the functionality of your REST APIs by previewing the server app.

You can perform a HTTP Request from Client app to hit the server’s HTTP endpoint and perform server tasks. For example, if the HTTP Request from the client hits the /createuser endpoint on the server, a server flow is executed to create a new user.
