Deciding the optimal time to start a new JavaScript file and effectively organizing source code

Embarking on a substantial map application project involving approximately 5,000 lines of JavaScript, I am contemplating changing my approach to file organization. Traditionally, I would consolidate all code into a single file named 'main.js', but now I am considering distributing components across multiple JavaScript files for improved organization. Is this a wise decision for a more structured project layout?

I am seeking advice on the best practices for this new approach. How do I determine when a piece of code should be separated into its own file? Are there any guidelines or rules of thumb to follow when making this decision?

Answer №1

Breaking up your code into separate files is crucial for effective organization. The way you decide to separate your code will depend on the nature of your project and how you believe it can be best structured. Here are some strategies to consider:

  1. Organize code into reusable objects, grouping similar objects into modules contained in individual files.

  2. Group related objects and functions that serve a specific functionality in one file, such as functions for animation.

  3. Create separate files for utility functions that can be reused across various projects without the need for restructuring.

  4. For reusability, separate small code chunks that may be used in future projects into their own files. Ensure that any dependent functions or utilities are also included in their own files for easy inclusion in future projects.

  5. Isolate code that is specific to the current application or user interface into separate files to keep it distinct from reusable parts.

Remember that the most efficient deployment strategy involves combining most of your separate files into a single, minimized file for improved browser performance. This concatenation and minimization should be automated as part of your build process, keeping individual files separate in your source control system.

Answer №2

Absolutey, it's crucial to organize your project into separate files. The same principles you apply to other programming languages should be followed here. Effective programming techniques are applicable across the board, regardless of the specific language you are using.

Consider dividing your project into reusable objects. Each object should have a clear and specific purpose. This way, you can build a library of objects that can be utilized in future projects.

It's highly recommended to get a hold of "JavaScript: The Good Parts" by Douglas Crockford.
