To build a rest point application, there are many options available like Akka Http, Finagle, Play Framework, Lagom etc. In our project, we are using Akka HTTP for building rest applications. We have lots of requests related to analytics. There are many requests which are very expensive. So, we faced an issue where our application was taking time to respond to some analytics. We have Continue Reading
If you are reading this then probably you have encountered the issue that comes while accessing fields with uploading a file, and if not then let me first tell you what’s the situation that I’m talking about here, Let’s see the code where we try to use fileUpload directive and formFields together
The semantic web is the next level of Web Searching where data is more important and it should be well defined. The semantic web is needed for making the web search more intelligent and intuitive to get the user’s requirement. You all can find some interesting point on the Semantic Web here. Triples is an atomic entity in RDF. It is composed of subject-predicate-object. It Continue Reading
In this blog we’ll be discussing about the Routing DSl provided by Akka HTTP High level Server Side API. Akka HTTP provides a very flexible “Routing DSL” for elegantly defining RESTful web services. It picks up where the low-level API leaves off and offers much of the higher level functionality of typical web servers or frameworks, like deconstruction of URIs, content negotiation or static content serving. Continue Reading
Hi Folks ! Lately there have been a lot of tools that allow us to build rest APIs like the following : Akka Http Play Scalatra http4s Finch Spray In my blog today, I will be discussing Akka Http and its counterparts(competitors) in terms of their advantages, disadvantages, performance and use cases. Let us begin comparsion of Akka-Http with Scalatra. Scalatra is a thread based,it Continue Reading
Hello folks, Hope you are enjoying your coding days!!! in this blog, I will explain a cool technology named Akka-Http which i have recently explored in my coding days!! Introduction The Akka HTTP implements a full server- and client-side HTTP stack on top of akka-actor and akka-stream. It’s not a web-framework but rather a more general toolkit for providing and consuming HTTP-based services. Akka.Http comes with Continue Reading
Hello Folks, Welcome back again in the series of Neo4j with Scala . Let’s start our journey again. But before starting our journey here is the links for recap who join late us in the journey : Getting Started Neo4j with Scala : An Introduction Neo4j with Scala: Defining User Defined Procedures and APOC Neo4j with Scala: Migrate Data From Other Database to Neo4j Neo4j Continue Reading
Hello All, In this blog we are using Swagger to generate document of Akka-HTTP. For Swagger you can get more information from Introduction to Swagger . For Akka you can get more information from Introduction to Akka-Http You can find complete code here. build.sbt file of the project contains all dependency. SwaggerDocService.scala AkkaSwagger.Scala Get the Json in response by hitting localhost:8080/api-docs/swagger.json You can get Continue Reading
Hi guys, In my last blogs I explained how one can create a self-signed certificate and KeyStore in PKCS12. You can go through the previous blog, as we’ll be needing certificate and keystore for handling HTTPS requests. https://blog.knoldus.com/2016/10/18/create-a-self-signed-ssl-certificate-using-openssl/ https://blog.knoldus.com/2016/10/26/how-to-create-a-keystore-in-pkcs12-format/ Akka-HTTP provides both Server-Side and Client-Side HTTPS support. In this blog I’ll be covering the Server-Side HTTPS support. Let’s start with “why do we need server-side HTTPS support?” If we want the communication between the browser and Continue Reading
In this tutorial , we will be demonstrating how to make a REST service in Spark using Akka-http as a side-kick 😉 and Cassandra as the data store. We have seen the power of Spark earlier and when it is combined with Cassandra in a right way it becomes even more powerful. Earlier we have seen how to build Rest Api on Spark and Couchbase Continue Reading
In my previous blog, I explained how you can implement WebSocket server using Akka-HTTP. As you know, Microservice architecture has become very popular in recent years. This architecture fits perfect 1) When you want to give support of your application for many platforms such as web, mobile etc. 2) When your application consists of multiple services such as order service, account service, payment service etc. Continue Reading
Couchbase and Apache Spark are best so far , for the in-memory computation. I am using akka-http because its new in the business. If you are not a big fan of akka-http and don’t think it is yet ready for production then you can take a look on this blog, which displays how to do the same task using Spray. If you are new to all Continue Reading
Sometimes while developing REST API’s we want to log the response time of our REST APi for the sake of better tuning. We are going to discuss the same case here and will see how to do that in Akka-http . So sometime before while I was working on akka-http while developing a spark-akka-http-couchbase Lightbend activator template , a weird use case came in-front of Continue Reading
