Since the past few years, I have been writing codes for very large web applications and with a team of other React developers to organize the code so, it can be scaled as the application evolves. I am writing this blog as a set of advice on structuring large Reactjs web application that has been developed by small and medium size teams.

There are lots of articles and blogs out there on structuring React.js web applications, but however; I am not completely satisfied with their approaches and explanations. So, I decided to invest my time to educate others and provide the valuable information on the best possible way to organize the future React projects.

So, listed are the principles that I along with my team take into consideration while structuring React apps. The adroit developers at Bacancy Technology make sure to apply these approaches in all the “JS Apps”.

So, let get started.

Stick to the rules: Sorting file is never a good idea

– Applications/ – components/ – containers/

In my initial stage, the most common advice was to separate the components into stateful components as well as pure functions.

The purpose of following this method is that your components can be reused elsewhere. This could be the case for many projects, but I am genuinely not sure that how it could be for all applications. Let me keep the functionality thing apart, even placing the pieces of components that hold the same potential to perform into the distinct corner of your file system is counter-intuitive and counter-productive.

Components: Everything deserve its name

Accurately and grammatically correct name can save you from questions and your teammates from misperceptions. So, usually in every folder of a component folder, I keep the first later as capital one so whenever I search for a file by name or a project, I can easily identify by the name. i.e. “header VS Header”.

Naming is not just the creative part, but it is one of the hardest parts of software development. So, it is advisable to think three times before you introduce new entities like functions, methods or variables. One more piece of advice is inline the code if it is specifically applied just once as it will make reading a code a lot similar to watching your favorite video across various devices.

Exploit the file system

Code requires a standard procedure that starts with the hierarchy of directories. So, before you access the file, it is needless to say that it should be very well organized and reflects the same hierarchy so you can save your valuable time in navigation across codebase

Do not limit yourself with the directories, you can simply split code between files without any sort of hesitation! It is advisable to not place multiple entities into single, put the one per file. Doing so will improve your navigation experience and files list will become a kind of your codebase. So, moving files in-between the directories is a lot simpler than moving sections itself across codebase files.

Routes

Make sure to keep all the routes in the current bundle. As it is completely ok to have a few route files for the same bundle. Usually, I assemble all keep routes in every route’s file and export them as a collection. At a later stage, in my entry point of application, I simply import all the routes together and merge them into one array inside Router.

File size recommendation

It is advisable to not surpass the size above 300 lines per file. Anything bigger than that may warrant splitting.

Keep your tools separated to affect it from general business logic

Repeating coding will be there in any sort of application, it is usually separated as utilities, libraries or helpers, which will assist in structuring unique components of business logic

Keep in mind that your tools should be only separated from business logic, not from the codebase. So hold yourself at a certain edge of process separation as the single directory with all the tools and time will grow up significantly.

Users/
  generic/
    helpers/
      is-email.js
  Profile/
    isEmail() required on user profile page
  SignUp/
    isEmail() also required in sign up process

If the two modules are using the same tool, then it is advisable to put the tool closet to the parent module. So you will have multiple equally names directories along with the tools in your application. It not advisable to have tools from sibling directories, following the rule of thumb only one direction should be imported across the app for the simple maintenance of code.

Your App Structure must reflect your business logic

Give your business logic the utmost preference over anything. People would easily relate to your business logic if it coming from real life experiences instead of framework abstractions. You cannot simply avoid the influence of tools or framework to your application, but I would advise you to minimize it. In case if it is acceptable, then isolate business logic from tools and frameworks abstractions.

In my initial stage of react/redux app development, I was in search of the finest practices in codebase structuring. As I wasn’t in favor of time component/container approach. Even after the half of decade practices I still don’t see that much difference between components and containers.

So, fortunately, I come up with my very own approach – hierarchy of directories upon the business logic models. As it does not distinguish components by presentational or logical type instead states that all components are equal and each of the components includes both logic as well as presentation.

Wrapping up

This folder structure has saved me lots of valuable time and it is a lot simpler than all related entities assembled together. As I mentioned above, I have devoted my time to write this blog to help you organize your project in many ways and trust me this is the reason I loved it and you will too love it for sure.
