  "account": "Every Next.js application begins with a simple structure: a few routes, a clean folder tree, and straightforward app logic. However, as the application scales, the codebase becomes more complex, with hundreds of pages, routes, and components. Features spread across these elements, making it difficult to maintain or debug them. Multiple teams and developers often work on the same files, leading to conflicts, regression testing, and reinventing the wheel. Both developers and AI tools find it challenging to comprehend scattered code, and reusability becomes a significant issue. Development slows down as much of the time spent on new features is spent reading and updating the code.\n\nThe solution lies in adopting a modular architecture. Most other frameworks, like Nuxt or NestJS, split code by feature, creating modules that isolate all the logic for a feature. This approach makes the code easier to maintain, debug, scale, remove, and reuse. In this article, I will explain why modular architecture is the best solution for Next.js applications and introduce the next-modular package that enables modular architecture in Next.js.\n\nModular architecture differs from multi-zones and microfrontends. Multi-zones splits the application by URL, creating separate Next.js apps for each area of the site. This approach increases operational complexity and does not address the original problem of scattered code. Microfrontends further split the product into fully separate apps, which also increases complexity and makes reuse and navigation difficult.\n\nModular architecture, on the other hand, splits the code inside a single Next.js app by feature. A module is a self-contained folder that holds everything a feature needs, including pages, API routes, components, and logic. Modules plug into the app through a single configuration entry. Here's an example of defining a module in next-modular:\n\n```javascript\nimport { defineModule, route } from 'next-modular';\n\nimport * as cart from './routes/cart';\nimport { checkoutHandler } from './server/api/checkout';\n\nexport const checkoutModule = defineModule({\nname: 'checkout',\nbasePath: '/checkout',\nroutes: [route('/cart', cart)],\napiRoutes: [{ path: '/checkout', handler: checkoutHandler }],\n});\n```\n\nIn the configuration file:\n\n```javascript\nimport { myModule } from './modules/myModule';\n\nexport default {\nmodules: [myModule],\n};\n```\n\nThis approach addresses the downsides of multi-zones and microfrontends. Setting up and maintaining modules is easy, and there are no extra apps or servers. Shared state, logic, and context work seamlessly, and navigation stays within the app. Reusability is also simple - copy the module folder into another project or publish it as a package and install it. An auth module built for one product can be easily integrated into another with a single installation and one line in the configuration. Developers and AI tools can also read and maintain the code with ease.\n\nThe only trade-off is that modular architecture does not allow for independent deploys. Everything ships as a single app. However, for most products, this is an acceptable trade-off, as it is the right call in most cases. With next-modular, Next.js can now support a modular architecture, making it easier to build scalable applications.",
