# TwoService and NestJS
## Instruments
1) PostgreSQL - 15.6
2) Node - 20.12.2
3) npm - 10.5.0
4) nest - 10.3.2
## RUN TwoService
`cd service && npm i`
### ENV-Express
__Please create `.env` file in service/__
```USER_DB = your_user_postgres
PASSWORD = your_password_postgres
PORT_DB = your_port_for_db_postgres (standart 5432)
DATABASE = user_action_service_db
HOST = localhost
NODE_ENV = development (production without logger)
PORT_1 = 8000
PORT_2 = 8001
PORT_3 = 8002
```
### Database-Express
__If you not have psql (command in terminal) make:__
1) Open PostgreSQL (example pgAdmin4)
2) Copy content from ~/sql_scripts/dbUserService.sql
3) Put content to sql-query and execute
4) Analog for generate data ~/sql_scripts/generateUsers.sql
5) Well done, db,table,func,proc,view created!
__If you have psql command in terminal make:__
- `npm run init_db`
- `npm run generate_data`
### Start express
__This 2 services and use one swagger!__
first service use port 8000:
- Create user,change user, get users
- Choose in swagger localhost:8000
second service use port 8001:
- Save create/change use to history and get history by id user with limit and page
- Choose in swagger localhost:8001
third service - main service use port 8002:
without restart: `npm run start`
with restart: `npm run dev`
This using swagger GO: `http://localhost:8002/docs`
## RUN NestJS
`cd nestjs-project && npm i`
### ENV-NestJS
__Please create `.env` file in nestjs-project/__
```USER_DB = your_user_postgres
PASSWORD = your_password_postgres
PORT_DB = your_port_for_db_postgres (standart 5432)
DATABASE = user_action_service_db
HOST = localhost
NODE_ENV = development (production without logger)
PORT = 7000
```
### Database-NestJS
For NestJS create database in postgre SQL
`CREATE DATABASE user_action_service_db`
### Migration

` npm run migration:gen ` __then add in func "up" next__
``` await queryRunner.query('
INSERT INTO users (first_name, last_name, age, gender, has_problems)
SELECT
'FirstName' || i,
'LastName' || i,
(RANDOM() * 50 + 20)::INTEGER,
CASE WHEN RANDOM() < 0.5 THEN 'Male' ELSE 'Female' END,
CASE WHEN RANDOM() < 0.5 THEN true ELSE false END
FROM generate_series(1, 1000000) s(i);
');
```
### Start nestjs
`npm run start`
with log
`npm run start:dev`
This using swagger, GO: `http://localhost:7000`
