Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Getting Started With Schematics

This repository contains helper schematics for generating unified structure of NestJS components written in hexagonal architecture and CQRS pattern.

Current Schematics

Component

Generates a new component, prepares modules and nested folders (application, domain, infrastructure, ui)

Running nest g -c @betsys/nestjs-schematics component for a component named example will generate the following structure:

└── src/
    └── component/
        └── example/
            ├── application/
            │   └── example-application.module.ts
            ├── domain/
            │   └── example-domain.module.ts
            ├── infrastructure/
            │   └── example-infrastructure.module.ts
            ├── ui/
            │   ├── http/
            │   │   └── example-http.module.ts
            │   └── example-ui.module.ts
            └── example.module.ts

CQRS

Generates a command or query with a handler.

Running nest g -c @betsys/nestjs-schematics cqrs for a component named example will generate the following structure:

└── src/
    └── component/
        └── example/
            └── application/
                ├── command/
                │   ├── example-command.handler.ts
                │   └── example-command.ts
                └── query/
                    ├── example-query.handler.ts
                    └── example-query.ts

Usage

To install, simply do:

npm install --save-dev @betsys-nestjs/schematics

Then in the project start generating your code by using the nest-cli.

nest g -c @betsys/nestjs-schematics ${schematic}

That's it! The cli wizard will walk you through the configuration.

Monorepo and nested directories

By default the library works for <project-root>/src/component/<component-name> directory structure. If you are using a monorepo, you can specify the root dir by a rooDir parameter.

└── apps/
    └── my-app1/
    └── my-app2/
        └── src/
            └── component/
                └── example/
                    └── application/
                        ├── command/
                        │   ├── example-command.handler.ts
                        │   └── example-command.ts
                        └── query/
                            ├── example-query.handler.ts
                            └── example-query.ts
nest g -c @betsys/nestjs-schematics ${schematic} --rootDir=apps/my-app2

This command will generate the files in <project-root>/apps/my-app2/src/ directory.
