NestJS GraphQL Monolith Fastify

Description

Full NodeJS boilerplate of a NestJS GraphQL monolithic backend API using PostgreSQL as the database.

Technologies

In terms of languages this template takes a NestJS GraphQL Code First Approach, so it's fully written in TypeScript.

In terms of frameworks it uses:

NestJS as the main NodeJS framework;
Fastify as the HTTP and WS adapter;
Mercurius as the GraphQL adapter for Fastify;
MikroORM as the ORM for interacting with the database;
Sharp for image manipulation and optimization.

Features

Configuration (adds most used config classes):

Cache with Redis;
GraphQL with subscriptions and GraphQL through Websockets;
MikroORM with SQLite in development and PostgreSQL in production.

Authentication:

JWT Authentication (local OAuth) for HTTP;
Custom Session Authentication for Websockets (based on Facebook Messenger Design);
Two-Factor authentication with email.

Uploader:

Basic image only uploader with Sharp optimizations for a generic S3 Bucket.

Pagination:

Has the generics for Edges and Paginated types;
Relay cursor pagination function.

Module Folder Structure

In terms of folders each module is divided as follows:

^{NOTE: this is only a recommendation you can always use your own approach as long as they work with
NestJS.}

C:/home/user/Home/IdeProjects/{project-folder}/src/{module-name}:.
├─── entities
│    │ {something}.entity.ts
│    ├─── gql:
│    │     {something}.type.ts
├─── interfaces
│     {something}.interface.ts
├─── enums
│     {something}.enum.ts
├─── dtos
│     {something}.dto.ts
├─── inputs
│     {something}.input.ts
├─── tests
│     {something}.spec.ts
│ {module-name}.module.ts
│ {module-name}.service.ts
│ {module-name}.resolver.ts

Entities (entities):

Where you save all your entities;
The entities are the classes that represent the database tables and the Graphql Object Types;
These are normally decorated with the @Entity decorator and the @ObjectType decorator;
File Extension: {something}.entity.ts
Gql (gql):
- Where you save the Generic Graphql Object Types (ex: PaginatedUsers, etc.);
- These are normally decorated with the @ObjectType decorator;
- File Extension: {something}.type.ts

Interfaces (interfaces):

Where you save all the interfaces and TypeScript types;
File Extension: {something}.interface.ts

Enums (enums):

Where you save all general enums and Enum Type;
File Extension: {something}.enum.ts

Dtos (dtos):

Where you save all the DTOs (Data Transfer Objects) mainly for your Queries;
These are normally decorated with the ArgsType decorator;
File Extension: {something}.dto.ts

Inputs (inputs):

Where you save all the GraphQL Input Objects mainly for your Mutations;
These are normally decorated with the @InputType decorator;
File Extension: {something}.input.ts

Tests (tests):

Where you save all the unit tests for your module's services, resolvers and controllers;
These are normally the spec files generated by the cli, but you still need to move them to this folder;
File Extension: {something}.spec.ts

Optional Folders:

Embeddables (embeddables):
- Where you save all your JSON Fields for your database tables;
- These are normally decorated with the @Embeddable decorator;
- File Extension: {something}.embeddable.ts
Guards (guards):
- Where you save all your NestJS Guards related to your module;
- File Extension: {something}.guard.ts

Initial Set Up

Installation

$ yarn install

Database Migrations

# creation
$ yarn migrate:create
# update
$ yarn migrate:update

Running the app

# production mode
$ yarn start

# watch mode
$ yarn start:dev

# debug mode
$ yarn start:debug

Local setup

Create a repo using this template;
Install the dependencies:

$ yarn install

Create a .env file with all the fields equal to the example.
Run the app in development mode:

$ yarn start:dev

Unit Testing

BEFORE EACH TEST (Individual or All):

Check if NODE_ENV is not production;
Remove the current test.db (if exits);
Create a new test.db.

# remove test.db
$ rm test.db
# create a new test.db
$ yarn migrate:create

All tests:

# unit tests
$ yarn run test

Individual test:

# unit tests
$ yarn run test service-name.service.spec.ts

Deployment

Steps:

Go to DigitalOcean, Linode or Hetzner;
Create a server running Ubuntu LTS;
Install dokku;
Run the following commands on your server for dokku initial set-up:

$ cat ~/.ssh/authorized_keys | dokku ssh-keys:add admin
$ dokku domains:set-global your-global-domain.com

Create a new app and connect git:

$ dokku apps:create app-name

Add the Postgres plugin to dokku, create a new PG instance and link it to the app:

$ sudo dokku plugin:install https://github.com/dokku/dokku-postgres.git postgres
$ dokku postgres:create app-name-db
$ dokku postgres:link app-name-db app-name

Add the Redis plugin to dokku, and create a new Redis instance and link it to the app:

$ sudo dokku plugin:install https://github.com/dokku/dokku-redis.git redis
$ dokku redis:create app-name-redis
$ dokku redis:link app-name-redis app-name

Add all the other configurations as in the example file:

$ dokku config:set app-name URL=https://your-domain.com ...

On the project folder on your local computer run the following commands:

$ git remote add dokku dokku@server-public-ip-address:app-name
$ git push dokku main:master

Finally set up SSL and a domain for your app:

$ sudo dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git
$ dokku config:set --global DOKKU_LETSENCRYPT_EMAIL=your-email@your.domain.com
$ dokku domains:set app-name your-domain.com
$ dokku letsencrypt:enable app-name
$ dokku letsencrypt:cron-job --add
