@nestjs-mod/schematics

A collection of utilities for unifying NestJS applications and modules.

Description

NestJS is a great framework and you can do great things with it, but often when developing a large number of applications within the same organization, we end up with different application architectures, file structures, and a lot of duplicate code.

The NestJS-mod collection of utilities are designed to unify applications and modules, and also introduce new logical options for dividing responsibilities between modules (Core, Feature, Integration, System, Infrastructure).

Since all parts of the application are unified, you can create a report on the entire project infrastructure.

Getting started

Create new application

Commands for create empty NestJS-mod application

# Create empty nx project
npx --yes create-nx-workspace@17.2.8 --name=project-name --preset=empty --interactive=false --nx-cloud=false

# Go to created project
cd project-name

# Install all need main dev-dependencies
npm install --save-dev @nestjs-mod/schematics@latest

# Create NestJS-mod application
./node_modules/.bin/nx g @nestjs-mod/schematics:application --directory=apps/app-name --name=app-name --projectNameAndRootFormat=as-provided --strict=true

Start created application

# Prepare all files
npm run manual:prepare

# Start application in dev mode
npm run serve:dev:app-name

# Build and start application in prod mode

## Build
npm run build:prod:app-name

## Start
npm run start:prod:app-name

Create new library

Commands for create empty NestJS-mod library

# Create NestJS-mod library
./node_modules/.bin/nx g @nestjs-mod/schematics:library feature-name --buildable --publishable --directory=libs/feature-name --simpleName=true --projectNameAndRootFormat=as-provided --strict=true

Add created library to apps/app-name/src/main.ts

// Example without options
bootstrapNestApplication({
  ...
  modules: {
    feature: [FeatureName.forRoot()],
  }
});

// Example with options
bootstrapNestApplication({
  ...
  modules: {
    feature: [FeatureName.forRoot({
      configuration: { optionsName: 'options name' },
    })],
  }
});


// By default, in the example, the application looks for env by the key `APP_NAME_ENV_NAME`, but you can override it, for example:
bootstrapNestApplication({
  ...
  modules: {
    feature: [FeatureName.forRoot({
      environments: { envName: 'env name' },
    })],
  }
});

Create an infrastructure report

You can generate a report for all modules and their configurations.

# Build all applications and library
npm run build

# Generate markdown report
npm run docs:infrastructure

After which the file INFRASTRUCTURE.MD appear in the application folder apps/app-name.
