nextjs-monorepo-tools

nextjs-monorepo-tools is package that let you convert your nextjs project to monorepo. Follow the example below to know how you can do it.

Example Project

Please check out the example project here – nextjs-monorepo-example

Getting Started

1. You need to update your project's structure like this:

.
|-- apps
	|-- project-one
	   |-- pages
	   |-- next.config.js
	   |-- tsconfig.json
	|-- project-two
	   |-- pages
	   |-- next.config.js
	   |-- tsconfig.json
|-- libs
	|-- common-component
		|-- common-component.tsx
|-- package.json
|-- tsconfig.json

2. Create in the root new tsconfig.json and then add follow params:

{
  "compilerOptions": {
    // ...
    "baseUrl": ".",
    "paths": {
      "@common/common-component": ["libs/common-component"]
    }
  }
}

3. Add to your project nextjs-monorepo-tools package as dependency.

4. Add custom Webpack configuration to next.config.js:

const { patchWebpackConfig } = require("nextjs-monorepo-tools");

const config = {
  webpack: patchWebpackConfig({
    commonDirs: ["libs"], // "libs" is directory for shared modules
  }),
};

module.exports = config;

That should be done for every project in your monorepo.

5. Update package.json

Because how we have two projects we have to update package.json to have dev, build, start commands for each project.

"scripts": {
	"dev:project-one": "next dev apps/project-one",
	"dev:project-two": "next dev apps/project-two",
	"build:project-one": "next build apps/project-one",
	"build:project-two": "next build apps/project-two",
	"start:project-one": "next start apps/project-one",
	"start:project-two": "next start apps/project-two"
}

That's all!

How to add new common module?

Just create new directory in libs and add new section in tsconfig.json.

{
  "compilerOptions": {
    // ...
    "paths": {
      "@common/common-component": ["libs/common-component"],
      "@common/common-component-two": ["libs/common-component-two"]
    }
  }
}
