Jscript include file

This could sound the most obvious way to solve this problem. If you are looking to solve this issue with modern javascript framework see below. When you import. For example if you script requires jQuery you will need to import first jQuery library and then your script:.

In the order above your-script. The next code will load the code from your-script. The problem with the code above is that is asynchronous and you can predict the order of loading. Imagine you have JavaScript library which consists of many scripts, and one loader. Some parts are dependent on one another. Imagine you include another main. The issue was that sometimes main. The usage of cascading onload event handler in the loader.

It is a very difficult issue if you need include scripts that are dependent on one another.

Use a pre-processor which will run through your JS files for example looking for patterns like " import somefile. If you are using Ruby on Rails then you can give Jammit asset packaging a try, it uses assets. Try using a module loader like RequireJS or a script loader like LabJs with the ability to control the loading sequence as well as taking advantage of parallel downloading. I can understand that it may not feel intuitive if you are from a Server-side background but this is the way things are.

For front-end developers this problem is typically a "deployment and packaging issue". Stack Overflow for Teams — Collaborate and share knowledge with a private group.
