Hypermedia as the engine of application HATEOAS


This information came to my knowledge when I was implementing a REST service for my company.


A REST client enters a REST application through a simple fixed URL. All future actions the client may take are discovered within resource representations returned from the server. The media types used for these representations, and the link relations they may contain, are standardized. The client transitions through application states by selecting from the links within a representation or by manipulating the representation in other ways afforded by its media type. In this way, RESTful interaction is driven by hypermedia, rather than out-of-band information.



To learn HATEOAS,

REST VS SOAP

SOAP and REST both allow you to create your own API. API stands for Application Programming Interface. It makes it possible to transfer data from an application to other applications. An API receives requests and sends back responses through internet protocols such as HTTP, SMTP, and others.  Many popular websites provide public APIs for their users, for example, Google Maps has a  public REST API  that lets you customize Google Maps with your own content. There are also many APIs that have been created by companies for internal use. There are significant differences between SOAP and RESTful web services. The bullets below break down the features of each web service based on personal experience. REST RESTful web services are stateless. You can test this condition by restarting the server and checking if interactions survive. For most servers, RESTful web services provide a good caching infrastructure over an HTTP GET method. This can improve the performance...

SVN to GIT Migration with revision history

This blog explains the process I have followed while moving one of code branch of one of the projects to Gitlab. SVN to Git migration can be done using the git-svn command in Git.  Documentation about this command can be found from here. https://git-scm.com/docs/git-svn My Company svn repository can be accessed using two ways svn+ssh://192.168.x.x/usr/local/ svnroot/branches/PROJECT/PROJECT_BRANCH http://svn.companyName.net/repos/svnroot/branches/ PROJECT/PROJECT_BRANCH SVN to GIT migration can be done using one of the above-mentioned URLs.  Git can be installed and configured to use its inbuilt SSH client or third party ssh client ( https://6xgate.github.io/TortoisePlink/ ) First of all, this process should be run in a server where the system does not go idle. I have tried this on my PC. But when I have locked the PC, it crashes. Therefore I have tried this in one of our internal server. I have tried to get SVN revision history when the P...

Java 11 Modularity and Spring REST

I have recently started working on creating a REST API for a client project.  I was using Java 8 for my past developments. Since Java 11 was introduced in the last September  (https://en.wikipedia.org/wiki/Java_version_history) I thought of developing the REST API in Java 11. Java 11 is having major changes after Java 8. Java 11 is having a concept of modules (This was introduced after Java 9). Several libraries are acting as separate modules. Those are not included in JDK and those have to be imported separately. Ref : http://openjdk.java.net/jeps/261 (I have experienced this in JBoss7 also. They were using the module system and each service can specify which modules which are using. Those modules can be manually configured by the user.) One example is that you have to import the Java fx library separately (For GUI). Java-Fx is decoupled from JDK. <!-- https://mvnrepository.com/artifact/org.openjfx/javafx -->   ...
