OPA, an all-in-one web application development language, frees you from the pain of having to write HTML, CSS, JavaScript, SQL, and other varied web application development languages at the same time.
For a long time, the problem with web development is the complexity of its development. Even the development of a simple web application requires developers to understand multiple languages at the same time. You need HTML and CSS to take charge of the UI, JavaScript to develop client functions, server business logic needs to be developed using Java, PHP, and other server languages, and SQL to access the database.
How can I leave all the above languages away?
I have been fascinated by OPA in recent weeks, and it is committed to eliminating the tangle between different development languages in the Web development process. With OPA, you no longer need to use one language to develop the UI, another language to develop the client program, and the server language to develop the business logic, almost everything, opa can be used for development from customer-oriented code to database access.
Unlike some RIA (rich application) platforms, Opa users do not need to install any plug-ins on the browser. Part of the OPA code that needs to be run on the browser will be automatically compiled into JavaScript. In addition, the server code runs on the server. In fact, the OPA server is different from other server languages. It is a truly integrated solution. Unlike most platforms, you no longer have to install and maintain a separate web server, database server, application server, or middleware layer to run the entire application. The OPA platform provides everything from web services to database services, as well as a client and server framework.
Therefore, web applications developed using OPA can be incredibly streamlined, with almost no code for handling connections between various links, and fewer sample files and tedious work are common problems on other platforms. The example of a chat room can be completed with only 27 lines of OPA code. You can access http://opalang.org/learn.xmlt.pdf by using OPA to develop and deploy Web applications.
A perenrix problem with web development is its complexity and
The number of versions and technologies a developer must juggle to deploy even the simplest web application. you need HTML and CSS for the UI, JavaScript For the client-side code, a server-side platform such as Java or PHP for the back-end logic, SQL to access
The database, and potentially more.
What if all of that went away?
In recent weeks, I 've been fascinated with OPA, a new language that aims to eliminate all of the convoluted
Code-wrangling from web application development. with OPA, you don't use one language to script your UI, another to code your business logic, and so on. everything, from the client-facing code to the database access, is written in Opa.
Unlike with some rich Internet application (RIA) platforms, users don't need a browser plug-in to use OPA applications. the parts of your Opa code that need to run in the client browser are automatically compiled into JavaScript.
Other parts of your code run on the server, as appropriate. here, OPA is unusual in that it's a truly all-in-one solution. unlike most platforms, you don't need to install and maintain a stand-alone Web server, database server, application server, and Middleware
Layer to get going. The OPA platform provides everything, from the Web server to the database server to the client-and server-side frameworks.
As a result, web applications built with OPA can be incredibly compact. there's very little of the "glue code," boilerplate, and drudge work that characterizes most Web platforms. the sample application is a distributed Web-based chat client that comprises
Just 27 lines of OPA code. A full description of how to develop and deploy Web applications in Opa wocould be too long to include here, but I encourage you to browse the copious
Documentation available online.
