![]() The files are loaded asynchronously, which does not hold up the DOMContentLoaded event. #BUNDLE FILES INTO SINGLE TEXT FILE CODE#Requiring the necessary scripts when the page loads rather than using embedded tags gives you the best balance of code reuse and load time. You will need to be well acquainted with asynchronous programming to utilize this technique, but it is worthwhile.Ĭontemporary web applications tend to use technique #3. #BUNDLE FILES INTO SINGLE TEXT FILE FREE#Each module is free to load additional dependencies. This initializer script then requires/imports the major modules for the current page. Only a small initializer script gets loaded when the page is first loaded. This technique likely uses RequireJS or ECMAScript imports. This is more complicated, but allows you to reuse code, and have a tool replicate the code for you.ĭynamically require the scripts while the page is loading. Use a javascript bundler to combine many smaller scripts into a custom file per page. Too much code gets duplicated unless you use a javascript bundler. To be honest, this technique has always created more problems than it solves. Manually curate an additional file per page. Since there are differences in what each page needs, you have a number of options to manage that code. This code is used on enough pages and in enough use cases that it becomes worthwhile to deliver that code in the initial page load. Typically multi-page sites have common library and framework code. I will answer this from the standpoint of code organization and architecture, rather than which tools to use. Is there a tool for that? How does it work? I don't know if I misunderstood something but I literally put all my JavaScript into one file, now I have a big JS file and a lot of errors on the console (obviously) because the script can't find a 'register' button on the home page, a 'profile-foto' in the login form and a 'carousel' on the settings page. I googled for a while and I read people who claim they 'merge' their JS files into one single script so I tried it. It's a static website, each page has different elements so my first thought was "Ok so, one JS file per page, right?"Īnd I think that's fine for a 2-3pages websites, but what if it is a medium size one? I mean 10-15 pages (home, login, profile page, settings, a gallery page with a carousel, etc). Recently I got into DOM manipulation with JS, everything was sweet with one-page websites, but then I tried with projects with many html files and that's when I got confused. ![]()
