Architecture and Folder Structure
Learn how MakerKit allows you to build a Next.js application with a scalable and production-grade architecture and folder structure
MakerKit's primary goals are:
- Solid Foundations - providing you with the necessary code to get up and running with a Saas with minimal configuration
- Extendable and Adaptable - the ability to change and extend the codebase as efficiently as possible
While it's relatively simple to provide a functioning codebase, it's not always easy to make it:
- Simple - a clean codebase quickly understandable by anyone
- Easy to change - a codebase that can be easily changed to a particular domain
Once you start your project, you can begin unpicking and replacing the existing code to adapt it to your application's domain. At the same time, MakerKit may have pushed an update that fixed a bug or added a new cool feature.
The two projects will diverge and inevitably end up in a conflicting state.
Thankfully, Git makes it easy to merge conflicts. But it's still a hassle.
To reduce the number of possible conflicts, MakerKit ships with a particular folder structure:
- app - (site) - (app) - auth - invite - lib - components
These folders represent four separate layers. MakerKit is an Onion:
Let's talk about the lower level: the
core. This layer is a collection of building blocks, utilities, and APIs that make up MakerKit.
This part of the boilerplate is configurable and makes no assumptions about your domain.
You are still welcome to change this code to suit your needs, but you can expect most updates from upstream to change the code in this directory.
Lib and Shared Components
The mid-level is in two separate folders (to avoid excessive nesting):
lib: here is where we write most domain-related business logic (hooks, contexts, queries, mutations, etc.)
components: here is where we write components shared across the application
This layer can still be updated by the
upstream repository, but you should not expect too many changes unless it's additions for new features or bug fixes.
app layer is the outer layer of the application.
It's entirely dependent on your application, and you should not expect updates from upstream unless for fixing blatantly buggy code.
The kit splits the routes into three separate layouts:
(site): the routes that are accessible to everyone, even if they are not logged in
(app): the routes that are accessible only to logged-in users
auth: the routes that are accessible only to logged-in users, but only if they are not already logged in
Domain components are co-located together with their routes. This means that you can easily find the components that are used in a particular route.
For example, you find the authentication components at
eslint to check that imports are flowing correctly through your application: if this feds you up, you can remove them from the
eslint configuration at
