• The features will be relate with AWS
• If you want to implement database transactions. You must run MongoDB as a replication set.
• If you want to implement Google SSO.
  1. You must have google account, then set your app on google console to get the clientId and clientSecret.
  2. MongoDB as replication set
• If you change the environment value of APP_ENV to production, that will trigger.
  1. CorsMiddleware will implement src/configs/middleware.config.ts.
  2. Documentation will disable.

This section will describe the structure of the response.

_metadata useful when we need to give the frontend some information

Default response for the response

export class ResponseMetadataSerialization {
    languages: string[];
    timestamp: number;
    timezone: string;
    requestId: string;
    path: string;
    version: string;
    repoVersion: string;
    [key: string]: any;
}

export class ResponseDefaultSerialization {
    statusCode: number;
    message: string;
    _metadata?: ResponseMetadataSerialization;
    data: Record<string, any>;
}

_metadata useful when we need to give the frontend some information

Default response for pagination.

export class RequestPaginationSerialization {
    search: string;
    filters: Record<
        string,
        string | number | boolean | Array<string | number | boolean>
    >;
    page: number;
    perPage: number;
    orderBy: string;
    orderDirection: ENUM_PAGINATION_ORDER_DIRECTION_TYPE;
    availableSearch: string[];
    availableOrderBy: string[];
    availableOrderDirection: ENUM_PAGINATION_ORDER_DIRECTION_TYPE[];
}

export class ResponsePaginationSerialization extends RequestPaginationSerialization {
    total: number;
    totalPage: number;
}

export class ResponsePaginationCursorSerialization {
    nextPage: string;
    previousPage: string;
    firstPage: string;
    lastPage: string;
}

export interface ResponsePagingMetadataSerialization
    extends ResponseMetadataSerialization {
    cursor?: ResponsePaginationCursorSerialization;
    pagination?: ResponsePaginationSerialization;
}

export class ResponsePagingSerialization {
    statusCode: number;
    message: string;
    _metadata?: ResponsePagingMetadataSerialization;
    data: Record<string, any>[];
}

We assume that everyone who comes here is programmer with intermediate knowledge and we also need to understand more before we begin in order to reduce the knowledge gap.

1. Understand NestJs Fundamental, Main Framework. NodeJs Framework with support fully TypeScript.
2. UnderstandTypescript Fundamental, Programming Language. It will help us to write and read the code.
3. Understand ExpressJs Fundamental, NodeJs Base Framework. It will help us in understanding how the NestJs Framework works.
4. Understand what NoSql is and how it works as a database, especially MongoDB.
5. Understand Repository Design Pattern or Data Access Object Design Pattern. It will help to read, and write the source code
6. Understand The SOLID Principle and KISS Principle for better write the code.
7. Optional. Understand Microservice Architecture, Clean Architecture, and/or Hexagonal Architecture. It can help to serve the project.
8. Optional. Understanding The Twelve Factor Apps. It can help to serve the project.
9. Optional. Understanding Docker. It can help to run the project.

Before start, we need to install some packages and tools. The recommended version is the LTS version for every tool and package.

Make sure to check that the tools have been installed successfully.

1. NodeJs
2. MongoDB
3. Yarn
4. Git

Clone the project with git.

git clone https://github.com/andrechristikan/ack-nestjs-boilerplate.git

This project needs some dependencies. Let's go install it.

yarn install

Make your own environment file with a copy of env.example and adjust values to suit your own environment.

cp .env.example .env

To know the details, you can read the documentation. Jump to document section

The project only provide unit testing.

yarn test

Finally, Cheers 🍻🍻 !!! you passed all steps.

Now you can run the project.

yarn start:dev

For docker installation, we need more tools to be installed in our instance.

1. Docker
2. Docker-Compose

Then run

docker-compose up -d

After all containers up, we need to configure mongodb as replication set In this case primary will be mongo1

1. Enter the mongo1 container

   docker exec -it mongo1 mongosh

2. Tell the primary to be as replication set

   rs.initiate({_id:"rs0", members: [{_id:0, host:"mongo1:27017", priority:3}, {_id:1, host:"mongo2:27017", priority:2}, {_id:2, host:"mongo3:27017", priority:1}]}, { force: true })

   will return response {status: ok}

3. Adjust env file

   ...
   
   DATABASE_HOST=mongodb://mongo1:27017,mongo2:27017,mongo3:27017
   DATABASE_NAME=ack
   DATABASE_USER=
   DATABASE_PASSWORD=
   DATABASE_DEBUG=false
   DATABASE_OPTIONS=replicaSet=rs0&retryWrites=true&w=majority
   
   ...

4. Restart service container

   docker restart service

The migration will do data seeding to MongoDB. Make sure to check the value of the DATABASE_ prefix in your.env file.

We need to rebuild, because migration build in separate module

``bash yarn build:migration

The Database migration used [NestJs-Command][ref-nestjscommand]

For seeding

```bash
yarn seed

For remove all data do

yarn rollback

You can check The ApiSpec after running this project. here

Ongoing update

Optional, if your mongodb version is < 5

Go to file src/common/database/services/database.options.service.ts and add useMongoClient to mongooseOptions then set value to true.

const mongooseOptions: MongooseModuleOptions = {
    uri,
    useNewUrlParser: true,
    useUnifiedTopology: true,
    serverSelectionTimeoutMS: 5000,
    useMongoClient: true // <--- add this
};

• Avoid Circular Dependency
• Consume component based / modular folder structure, and repository design pattern
• Always make service for every module is independently.
• Do not put controller into service modules, cause this will break the dependency. Only put the controller into router and then inject the dependency.
• Put the config in /configs folder, and for dynamic config put as environment variable
• CommonModule only for main package, and put the module that related of service/project into /src/modules. So, if we want to clear the unnecessary module, we just need to delete the src/modules/**
• If there a new service in CommonModule. Make sure to create the unit test in /unit.
