Speeding Up Post Load Script

Post-load script maybe one of the most challenging tasks for developers especially those that use a framework for building an Ajax application. In a framework setting, developers will always work in a setting wherein JavaScript is involved.

When post load happens, developers will be limited in their functions since the functions may need to run without the help of JavaScript. Without the proper coding, developers might slow down the process instead of speeding them up since asynchronous streaming of information is not there because JavaScript is not used.

Some usually see this as a disadvantage but if you know where to post load script, you may be able to use its delay to your advantage. An Ajax application, although asynchronous, does not have to relay all information at once. They still have to function like a website wherein some things have to be delayed a little bit so that it could make way for more important functions. Because it does not use JavaScript, it might not be asynchronous but it will be used in a better way such as loading additional functions that does not have to be loaded from the server.

Before doing that, developers have to ensure the actual use of the function so that they do not have to rearrange the function again. Post load script should be used when all things have been loaded. If this is the first function that should be used, then it should never be the post load script in the first place. Post load script should bring the information needed when everything else are in place.

Post load script does not even need time related function to ensure it is loaded when everything else are in place. All the developers have to do is to place the script right after the function so that the browser will naturally execute the function located on top of the post load script.

Any post load script could be used in the application which means it is not even a requirement that the post load script and the actual function are related. The post load script could be used as a tool for transitioning from one function to another or the post load script could be used as a complement for the function. Aside from the location of the coding, the source of the script should be reliable enough for developers to efficiently build the application.

The only challenge in post load scripting is to ensure that the script will be loaded on time. Post load script could come from the server or it could come from an outside source.

When it the post load script comes from the server, there is no problem but when it is loaded from the outside source, developers have to make sure that the outside source is reliable when the function is needed.  If it does not load on time then the post load script could be the cause of the Ajax application to slow down but when the post load script has a reliable source, the application will be faster than regularly coded Ajax application.
