Syeta Labs NestJS Starter

Description

Nest framework TypeScript starter repository.

In this starter you may find a working application pre configured with the PostgreSQL and JWT Auth.

Please go through Nest Docs before playing with the code.

Installation

To run the application you need to have PostgreSQL installed.

$ npm install

Running the app

# development
$ npm run start

# watch mode
$ npm run start:dev

# debug mode
$ npm run start:debug

# production mode
$ npm run start:prod

Running the app with docker 🐳

With Docker you can run it easily. Now port 3000 will be open and 9229 can be connected to debugger as well.

PostgreSQL is exposed via 5432 port.

$ docker-compose up

Database and ORM

For database we have used PostgreSQL. And for ORM we have used Knex.js with ObjectionJS.

Knex is an awesome query builder which is closer to SQL. Objection also a thin wrapper around Knex.

For all database migrations please use snake_case conversion when creating tables or columns. In PostgreSQL it is natural to work with snake_case when writing queries.

Knex will automatically map your snake_case names into camelCase on application side. Dont use snake_case in JS side. Instead always use camelCase. Read more

Please change the database name in docker-compose file and .env

Api Docs

Api docs can be geneated thanks to @nestjs/swagger package. Since we are using cli plugin you can comment your Dtos with JSDocs and the documentation will be done automatically. Please follow conventions mentioned here

Access swagger docs at http://localhost:3000/api-docs
Access swagger.json at http://localhost:3000/api-docs-json
