export const withAuth = (WrappedComponent: React.ComponentType) => {
  // ... (authentication logic)
};

nextjs-subscription-payments:

import { useUser } from '@/utils/useUser';
import { useRouter } from 'next/router';

const withAuth = (WrappedComponent) => (props) => {
  const { user, isLoading } = useUser();
  // ... (simpler authentication check)
};

The code comparison shows that SaaS-Boilerplate uses Next-Auth for authentication, while nextjs-subscription-payments implements a custom useUser hook. SaaS-Boilerplate's approach offers more flexibility and features, whereas nextjs-subscription-payments focuses on a simpler, more specific implementation.

Requirements

Node.js 20+ and npm

Getting started

Run the following command on your local environment:

git clone --depth=1 https://github.com/ixartz/SaaS-Boilerplate.git my-project-name
cd my-project-name
npm install

For your information, all dependencies are updated every month.

Then, you can run the project locally in development mode with live reload by executing:

npm run dev

Open http://localhost:3000 with your favorite browser to see your project.

Set up authentication

Create a Clerk account at Clerk.com and create a new application in the Clerk Dashboard. Then, copy the values of NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY and CLERK_SECRET_KEY into the .env.local file (which is not tracked by Git):

NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=your_clerk_pub_key
CLERK_SECRET_KEY=your_clerk_secret_key

In your Clerk Dashboard, you also need to Enable Organization by navigating to Organization management > Settings > Enable organization.

Now, you have a fully working authentication system with Next.js: Sign up, Sign in, Sign out, Forgot password, Reset password, Update profile, Update password, Update email, Delete account, and more.

Set up remote database

The project uses DrizzleORM, a type-safe ORM that is compatible with PostgreSQL, SQLite, and MySQL databases. By default, the project is set up to work seamlessly with PostgreSQL and you can easily choose any PostgreSQL database provider.

Translation (i18n) setup

For translation, the project uses next-intl combined with Crowdin. As a developer, you only need to take care of the English (or another default language) version. Translations for other languages are automatically generated and handled by Crowdin. You can use Crowdin to collaborate with your translation team or translate the messages yourself with the help of machine translation.

To set up translation (i18n), create an account at Crowdin.com and create a new project. In the newly created project, you will be able to find the project ID. You will also need to create a new Personal Access Token by going to Account Settings > API. Then, in your GitHub Actions, you need to define the following environment variables: CROWDIN_PROJECT_ID and CROWDIN_PERSONAL_TOKEN.

After defining the environment variables in your GitHub Actions, your localization files will be synchronized with Crowdin every time you push a new commit to the main branch.

Customization

You can easily configure Next.js SaaS Boilerplate by searching the entire project for FIXME: to make quick customization. Here are some of the most important files to customize:

public/apple-touch-icon.png, public/favicon.ico, public/favicon-16x16.png and public/favicon-32x32.png: your website favicon
src/utils/AppConfig.ts: configuration file
src/templates/BaseTemplate.tsx: default theme
next.config.mjs: Next.js configuration
.env: default environment variables

You have full access to the source code for further customization. The provided code is just an example to help you start your project. The sky's the limit ð.

In the source code, you will also find PRO comments that indicate the code that is only available in the PRO version. You can easily remove or replace this code with your own implementation.

Change database schema

To modify the database schema in the project, you can update the schema file located at ./src/models/Schema.ts. This file defines the structure of your database tables using the Drizzle ORM library.

After making changes to the schema, generate a migration by running the following command:

npm run db:generate

This will create a migration file that reflects your schema changes. The migration is automatically applied during the next database interaction, so there is no need to run it manually or restart the Next.js server.

Commit Message Format

The project follows the Conventional Commits specification, meaning all commit messages must be formatted accordingly. To help you write commit messages, the project uses Commitizen, an interactive CLI that guides you through the commit process. To use it, run the following command:

npm run commit

One of the benefits of using Conventional Commits is the ability to automatically generate a CHANGELOG file. It also allows us to automatically determine the next version number based on the types of commits that are included in a release.

Subscription payment with Stripe

The project is integrated with Stripe for subscription payment. You need to create a Stripe account and you also need to install the Stripe CLI. After installing the Stripe CLI, you need to login using the CLI:

stripe login

Then, you can run the following command to create a new price:

npm run stripe:setup-price

After running the command, you need to copy the price ID and paste it in src/utils/AppConfig.ts by updating the existing price ID with the new one.

In your Stripe Dashboard, you are required to configure your customer portal settings at https://dashboard.stripe.com/test/settings/billing/portal. Most importantly, you need to save the settings.

In your .env file, you need to update the NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY with your own Stripe Publishable key. You can find the key in your Stripe Dashboard. Then, you also need to create a new file named .env.local and add the following environment variables in the newly created file:

STRIPE_SECRET_KEY=your_stripe_secret_key
STRIPE_WEBHOOK_SECRET=your_stripe_webhook_secret

You get the STRIPE_SECRET_KEY from your Stripe Dashboard. The STRIPE_WEBHOOK_SECRET is generated by running the following command:

npm run dev

You'll find in your terminal the webhook signing secret. You can copy it and paste it in your .env.local file.

Testing

All unit tests are located alongside the source code in the same directory, making them easier to find. The project uses Vitest and React Testing Library for unit testing. You can run the tests with the following command:

npm run test

Integration & E2E Testing

The project uses Playwright for integration and end-to-end (E2E) testing. You can run the tests with the following commands:

npx playwright install # Only for the first time in a new environment
npm run test:e2e

In the local environment, visual testing is disabled, and the terminal will display the message [percy] Percy is not running, disabling snapshots.. By default, visual testing only runs in GitHub Actions.

Enable Edge runtime (optional)

The App Router folder is compatible with the Edge runtime. You can enable it by adding the following lines src/app/layouts.tsx:

export const runtime = 'edge';

For your information, the database migration is not compatible with the Edge runtime. So, you need to disable the automatic migration in src/libs/DB.ts:

await migrate(db, { migrationsFolder: './migrations' });

After disabling it, you are required to run the migration manually with:

npm run db:migrate

You also require to run the command each time you want to update the database schema.

Deploy to production

During the build process, database migrations are automatically executed, so there's no need to run them manually. However, you must define DATABASE_URL in your environment variables.

Then, you can generate a production build with:

$ npm run build

It generates an optimized production build of the boilerplate. To test the generated build, run:

$ npm run start

You also need to defined the environment variables CLERK_SECRET_KEY using your own key.

This command starts a local server using the production build. You can now open http://localhost:3000 in your preferred browser to see the result.

Error Monitoring

The project uses Sentry to monitor errors. In the development environment, no additional setup is needed: NextJS SaaS Boilerplate is pre-configured to use Sentry and Spotlight (Sentry for Development). All errors will automatically be sent to your local Spotlight instance, allowing you to experience Sentry locally.

For production environment, you'll need to create a Sentry account and a new project. Then, in next.config.mjs, you need to update the org and project attributes in withSentryConfig function. Additionally, add your Sentry DSN to sentry.client.config.ts, sentry.edge.config.ts and sentry.server.config.ts.

Code coverage

Next.js SaaS Template relies on Codecov for code coverage reporting solution. To enable Codecov, create a Codecov account and connect it to your GitHub account. Your repositories should appear on your Codecov dashboard. Select the desired repository and copy the token. In GitHub Actions, define the CODECOV_TOKEN environment variable and paste the token.

Make sure to create CODECOV_TOKEN as a GitHub Actions secret, do not paste it directly into your source code.

Logging

The project uses Pino.js for logging. In the development environment, logs are displayed in the console by default.

For production, the project is already integrated with Better Stack to manage and query your logs using SQL. To use Better Stack, you need to create a Better Stack account and create a new source: go to your Better Stack Logs Dashboard > Sources > Connect source. Then, you need to give a name to your source and select Node.js as the platform.

After creating the source, you will be able to view and copy your source token. In your environment variables, paste the token into the LOGTAIL_SOURCE_TOKEN variable. Now, all logs will automatically be sent to and ingested by Better Stack.

Checkly monitoring

The project uses Checkly to ensure that your production environment is always up and running. At regular intervals, Checkly runs the tests ending with *.check.e2e.ts extension and notifies you if any of the tests fail. Additionally, you have the flexibility to execute tests from multiple locations to ensure that your application is available worldwide.

To use Checkly, you must first create an account on their website. After creating an account, generate a new API key in the Checkly Dashboard and set the CHECKLY_API_KEY environment variable in GitHub Actions. Additionally, you will need to define the CHECKLY_ACCOUNT_ID, which can also be found in your Checkly Dashboard under User Settings > General.

To complete the setup, update the checkly.config.ts file with your own email address and production URL.

Useful commands

Bundle Analyzer

Next.js SaaS Starter Kit includes a built-in bundle analyzer. It can be used to analyze the size of your JavaScript bundles. To begin, run the following command:

npm run build-stats

By running the command, it'll automatically open a new browser window with the results.

Database Studio

The project is already configured with Drizzle Studio to explore the database. You can run the following command to open the database studio:

npm run db:studio

Then, you can open https://local.drizzle.studio with your favorite browser to explore your database.

VSCode information (optional)

If you are VSCode user, you can have a better integration with VSCode by installing the suggested extension in .vscode/extension.json. The starter code comes up with Settings for a seamless integration with VSCode. The Debug configuration is also provided for frontend and backend debugging experience.

With the plugins installed in your VSCode, ESLint and Prettier can automatically fix the code and display errors. The same applies to testing: you can install the VSCode Vitest extension to automatically run your tests, and it also shows the code coverage in context.

Pro tips: if you need a project wide-type checking with TypeScript, you can run a build with Cmd + Shift + B on Mac.
