For example: Since there are a lot of concepts in components that are built for Joomla, which may be called Conventions or Boilerplate Implementation. These things are always the same. I wanted something like a wireframe that could just take care of that for me all the time. If we were to have manually written this without any boilerplate tool or wire script that could help us write all the classes and tables and stuff and it took us 25 hours.[00:01:09](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h01m09s) Even if Joomla was to change, to be able to make a change in one place, and then compile it into all the components that I have developed. Then have them run stable again on Joomla, instead of having to go to every one of those components. We have gone beyond developing the most basic parts of a Component and ventured into some of its complexities.[00:01:40](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=00h01m40s) That is why showing a Hello World Component being built by Joomla Component Builder.

The basic steps. You would need a Joomla website. This Joomla website would preferably be on a developing environment, which is either offline or on a server which is not necessarily used in production.

If it is offline, the code can be opened in your IDE. JCB has the feature to extract this customized code out of your component and put it back on the compilation, a feature that does exist but which will not be discussed during this tutorial.

There is a Text Field, Radio, List, Multiple Selection, Checkbox, a Date Field. There are many types of Fields. Each Field independently is linked to a type, but there are some Database Settings within each Field as it gets linked into the Admin View since the Fields form the Columns of the Tables of the Admin Views. This is how a Component is set up.

Obviously, we want to have the ability to read and write on the Type table. If this is a 'read' only, it means that the data is in this Admin area can not be changed via Joomla. Unless you have added some JavaScript and some other nice conventions around your component that sort of creates data for that area dynamically as people use the component. This turns all the fields in the area as read-only, and if an attempt is made to change them, they never get submitted to the Database. Leave it always by Default as read and write.

At the Main Get, you can select the 'Listgreetings'(name only). The distinct functions of the Main Get and a Dynamic Get are that you will act upon the one in the compilation and the other one is only to view. So if you end up here(Looking) and click save, it will not play any role whatsoever in the compilation. It will play a role when a JCB Package is exported but that is a different subject which will not be dealt with here. Good practice would be that these two, Main Get and Dynamic Get would be the same. Since you can add Custom Gets, but there are not any Custom Gets set up right now, so none can be selected, but you can add more than just your normal Main Get to a Site View.[01:01:17](https://www.youtube.com/watch?v=IQfsLYIeblk&list=PLQRGFI8XZ_wtGvPQZWBfDzzlERLQgpMRE&t=01h01m17s) You can add the Main Get and then a bunch of Custom Gets which brings a large amount of data to the page from different variations of relationships.

Now a Site View is going to be added to our Component. It might be asked why the Component is not added to the Site View when the Site View has initially been created. I have considered such a possibility, but because of Database relationships and other reasons, felt that a better approach would be to link the Site Views at the Component area, instead of at the Site area. This gives us the option to use Site Views quite easily within other Components.
