Create app

# install nest-cli
$ npm install -g @nestjs/cli

# create a new web app
$ nest new my-nest-project

# change directory
$ cd my-nest-project

# run web app
$ npm run start:dev

Open you browser and type this url: http://localhost:3000

Generating a new resource

# create a new CRUD resource named user at modules folder
# the '--no-spec' option will tell nest-cli not to generate test file
$ nest g res modules/user --no-spec

It will automatically generate the below file and register it to app.module.ts:

• user.module.ts
• user.controller.ts
• user.service.ts
• user.entity.ts
• create-user.dto.ts
• update-user.dto.ts

Open http://localhost:3000/user. You will be surprised if all the endpoints for CRUD are created automatically.

You can adjust the files above to suite your use case.

Create a new module, service, and controller

If resource generator doesn’t suit your needs, you can also create manually with these command

# create new module at modules folder, named auth
$ nest g mo modules/auth --no-spec

# create new service at modules folder, named auth
$ nest g s modules/auth --no-spec

# create new controlle at modules folder, named auth
$ nest g co modules/auth --no-spec

It will automatically generate the below file and register it to app.module.ts:

• auth.module.ts
• auth.controller.ts
• auth.service.ts
