🎯 Getting Started

Initialize the project

Fork & clone repository:

# Don't forget to ⭐ star and fork it first :)
git clone --depth 1 <your_project_url> && cd next-boilerplate

Install the dependencies:

npm install

Initialize the project:

npm run init

Run the development server:

npm run dev

Open http://localhost:3000 with your browser to see the result.

Usage within a team

Those steps require a version of git >= 2.43.2 due to the sparse-checkout feature.

After initializing the project and pushing the changes to the repository, the other team members can follow the following steps:

Clone the repository:

git clone --depth 1 --filter=blob:none --no-checkout <your_project_url> && cd next-boilerplate && git checkout main

See more about the clone optimizations here.

Select the apps you want to work on:

As a team member you may not need to work on all the apps, you can select the apps you want to work on by running the following command (for all the repository enter full as the team name):

./bootstrap.sh <team_name>

Possible values for <team_name> are:

full
app
cron
docs
landing
infra

If you are the first one initializing the project please select the team_name: full. Otherwise the initialization script will not work correctly.

Initialize the project locally:

npm i -w packages && npm run init

After those steps you can start developing. Since you do not want to install the dependecies of all the apps when doing npm i use the -w flag to install the dependencies of the selected apps. For example if you run npm i -w apps/app at root it will install the dependencies of the app package only.

🗄️ Monorepo packages

This boilerplate uses npm workspaces to manage multiple packages in one repository. The following packages are available:

apps/app: The main application
apps/cron: The cron jobs
apps/docs: The documentation website
apps/landing: The landing page

To run a script in a package, you can use the following command:

npm run <script> --workspace=<package>

For example, to run the dev script in the app package, you can use the following command:

npm run dev --workspace=apps/app

or

cd apps/app && npm run dev

Each package has its own package.json file, so you can add dependencies specific to a package.

Please make sure to add the dependencies to the package.json file of the package you want to use them in. For example, if you want to add a dependency to the app package, you should add it to the app/package.json file with the following command:

npm install <package> --workspace=apps/app

or

cd apps/app
npm install <package>

If you install a dependency in the root package.json file, it will be available in all packages and in most cases, you don't want that.

Port for each package:

App: 3000
Docs: 3001
Landing: 3002

📃 Scripts Overview

The following scripts are available in the package.json:

init: Initializes the project by setting up your information
dev: Starts the development server (only the main application package)
build: Builds the app for production
start: Starts the production server
lint: Lints the code using ESLint
lint:fix: Automatically fixes linting errors
prettier: Checks the code for proper formatting
prettier:fix: Automatically fixes formatting issues
test: Runs unit and integration tests
preinstall: Ensures the project is installed with Npm
depcheck: Checks for unused dependencies

🐳 Container Stack

The boilerplate comes with a pre-configured Docker container stack and a dev container. The stack includes the following services:

PostgreSQL - A powerful, open-source relational database system
Redis - An in-memory data structure store, used as a database, cache, and message broker

To start the development container in vsCode see.

Ports:

Next.js: 3000
Docs: 3001
Landing: 3002
PostgreSQL: 5432
Redis: 6379

💻 Environment Variables handling

T3 Env is a library that provides environmental variables checking at build time, type validation and transforming. It ensures that your application is using the correct environment variables and their values are of the expected type. You’ll never again struggle with runtime errors caused by incorrect environment variable usage.

Config file is located at env.ts. Simply set your client and server variables and import env from any file in your project.

export const env = createEnv({
  server: {
    // Server variables
    SECRET_KEY: z.string(),
  },
  client: {
    // Client variables
    API_URL: z.string().url(),
  },
  runtimeEnv: {
    // Assign runtime variables
    SECRET_KEY: process.env.SECRET_KEY,
    API_URL: process.env.NEXT_PUBLIC_API_URL,
  },
});

If the required environment variables are not set, you'll get an error message:

  ❌ Invalid environment variables: { SECRET_KEY: [ 'Required' ] }

📝 Development tips

Internationalization

Optimization

In order to optimize the dictionary in client side you need to provide some information about what keys you really need from the dictionary. Then it will provide you a dictionary with only the required keys and not all the dictionary.

Usage

You can define the requirements for the dictionary like the example below. You can either import single keys like myTitle or import a whole object like mySecondPage.

When importing a whole object make sure you use almost all the keys inside in order to optimize the dictionary. If that's not the case, just define the needed keys one by one.

dictionaryRequirements({
  myTitle: true,
  myPage: {
    title: true,
  },
  mySecondPage: true,
});

Server-Side usage

import { MyComponentDr } from "@/components/my-component.dr";
import MyComponent from "@/components/my-component";
import { Locale } from "@/lib/i18n-config";
import { getDictionary } from "@/lib/langs";
import { dictionaryRequirements } from "@/lib/utils/dictionary";

export default async function Profile({
  params: { lang },
}: {
  params: {
    lang: Locale;
  };
}) {
  const dictionary = await getDictionary(
    lang,
    dictionaryRequirements(
      {
        profile: true,
      },
      MyComponentDr
    )
  );

  return (
    <main className="container m-auto flex flex-1 flex-col items-center justify-center p-6 pb-20">
      {dictionary.profile}
      <MyComponent dictionary={dictionary} />
    </main>
  );
}

In this example we load dictionary for two usages, one for the local component usage and the other for an external component usage. To make your life easier we suggest that for each component you create a my-component.dr.ts file and define the dictionary requirements inside (see Client-Side usage).

Client-Side usage

For each component that require the use of dictionary create a file named my-component.dr.ts. Then define the requirements inside:

import { dictionaryRequirements } from "@/lib/utils/dictionary";

import { OtherComponentDr } from "./other-component.dr";

export const MyComponentDr = dictionaryRequirements(
  {
    profilePage: true,
  },
  OtherComponent
);

In order to use it in your component your can import the Dr definition file and use it with TDictionary:

import { TDictionary } from "@/lib/langs";

import OtherComponent from "./other-component";
import { MyComponentDr } from "./my-component.dr";

export default async function MyComponent({
  dictionary,
}: {
  dictionary: TDictionary<typeof MyComponentDr>;
}) {
  return (
    <section className="p-2 text-foreground">
      <header>
        <h3 className="text-lg font-medium">{dictionary.profilePage.title}</h3>
      </header>
      <OtherComponent dictionary={dictionary} />
    </section>
  );
}

Traduction file

The files for traduction are located in apps/app/src/langs or apps/landing/src/langs depending on the package you want to use it in. If you want to add a new language, you can add a new file in the langs folder then modify the file i18n-config.ts and langs.ts.

File storage with S3

Upload files

When you want to upload files to a bucket s3 you have to main choices:

Upload the file directly from the client to s3
Upload the file to the server then to s3

Both have their pros and cons. The first one is faster and more secure because the file does not pass through the server. The second one is more secure because you can check the file before uploading it to s3.

In this boilerplate I choose the first solution because uploading the file to your server then to s3 can be expensive in terms of resources and time.

If you want to use the second solution you can use the multer library to upload the file to your server then to s3.

How it works?

The client sends a request to the server with the file name and file type.
The server sends a signed url to the client.
The client uploads the file to s3 with the signed url.
The client sends the file link to the server.
The server stores the file link in the database.

What if the client do not send the file link to the server?

To solve this problem I created a table named FileUploading and store all the upload request in it (step 2). Then I created a cron that check if the file is uploaded to s3 and used (see Dead files). If the file is not uploaded or not used within the expiration time (10 minutes) the cron delete the file from s3.

Dead files

A common problem in storing files to s3 is dead files. Dead files are files that are uploaded to s3 but not used in the application. To solve this problem. It's very hard to detect them manually if you do not set correctly your database.

For example, I upload a profile picture to s3 and I store the link in the database. If I delete the link in the database, the file is still in s3 and not used anymore.

To solve this I add a File table in the database, each time you need store a file link please use this table. Now we have a table that store all of our files but what if I need to override a file (like a profile picture). What I recommend is to unlink the File with the concerned table (here User) but leave the row in the table so the cron will detect it as a dead file an delete it. Why not deleting the file directly? Because the logic to delete the file from s3 and the database is in the same place is complex and any error can lead to a data loss and dead files. This is why this logic is centralized in the cron and not in the api route.

Git optimization

Depth clone

When you clone a repository, you can specify the depth of the clone. The depth is the number of commits from the tip of the branch. The depth is useful when you want to clone a repository but you don't need the full history.

Example:

git clone --depth 1 <repository-url>

In the (Getting Started)[#getting-started] section, I use the depth clone to clone the repository with only the last commit because you may not need the full history of the repository.

Here are good resources to learn more about the depth clone:

Sparse checkout

Those steps require a version of git >= 2.43.2 due to the space-checkout feature.

When you clone a repository, you can specify the files you want to clone. This is useful when you want to clone a repository but you don't need all the files.

Example:

git clone <repository-url> --no-checkout

In case of using this boilerplate with a team I specify the --no-checkout flag to clone the repository without the files. Then I use the git sparse-checkout command to select the files I want to work on. This is useful when you don't need to work on all the packages.

For example if you only want to work on the app package:

git sparse-checkout set apps/app

The command above is just and example, please use the bootstrap script to select the team you want to work on.

In order to avoid knowing all the commands you can use the bootstrap.sh script to select the team you want to work on. Example with the app team:

./bootstrap.sh app

You can revert the sparse checkout with the following command:

git sparse-checkout disable

Here are good resources to learn more about the sparse checkout:

https://github.blog/2020-01-17-bring-your-monorepo-down-to-size-with-sparse-checkout/

Recommended extensions

In order to install all recommended extensions please run: bash ./packages/scripts/install/install-extensions.sh

The dev container should install those extensions automatically but you can still execute the command above if there's a problem.

Database & Redis

By default the boilerplate needs a PostgreSQL and Redis database to work.

If you are using the devcontainer those services will start automatically when opening the project in vsCode.

If you are not using the devcontainer you can start the services with the following command:

docker compose -f ./docker/docker-compose.local.yml up -d

Git flow

The boilerplate uses the Git flow workflow.

The main branches are:

main: The main branch
rec: The staging branch
develop: The development branchs

Api development

For the interaction with the api you can use the trpc library. It's a library that allows you to create typesafe APIs with ease. See trpc.

Api errors

All the possible errors are defined in apps/app/src/langs/errors/<lang>.json

Banned keywords

In order to avoid using banned keywords in the codebase, we use the banned-keywords.sh. This script will check if there are any banned keywords in the codebase. By default all TODO and FIXME comments are banned.

Use this rules at your advantage ! For example if you are debugging a feature and you have commented some code you can use one of the following keywords to ensure this cannot be merged in the main branch.

// TODO: Debugging feature

❌ Common issues

Cannot commit

Error: .git-hooks/commit-msg: 6: git-conventional-commits: not found

This error occurs when the git-conventional-commits package is not installed. To fix this issue, run the following command:

npm install -g git-conventional-commits

This package is used to check the commit message format.

S3 upload error cors

See: https://www.scaleway.com/en/docs/storage/object/api-cli/setting-cors-rules/

Create a cors.json file

{
  "CORSRules": [
    {
      "AllowedOrigins": ["http://MY_DOMAIN_NAME", "http://www.MY_DOMAIN_NAME"],
      "AllowedHeaders": ["*"],
      "AllowedMethods": ["GET", "HEAD", "POST", "PUT", "DELETE"],
      "MaxAgeSeconds": 3000,
      "ExposeHeaders": ["Etag"]
    }
  ]
}

Then execute the following command:

aws --endpoint https://s3.fr-par.scw.cloud --profile=scaleway s3api put-bucket-cors --bucket <bucket_name> --cors-configuration file://cors.json

☁️ Cloud deployment

Please note that the following steps are for deploying the any application package.
