+# NEWAPP
+
+## This project was generated by [Flatlogic Platform](https://flatlogic.com).
+
+  - Frontend: [React.js](https://flatlogic.com/templates?framework%5B%5D=react&sort=default)
+
+  - Backend: [NodeJS](https://flatlogic.com/templates?backend%5B%5D=nodejs&sort=default)
+
+    <details><summary>Backend Folder Structure</summary>   
+
+    The generated application has the following backend folder structure: 
+
+    `src` folder which contains your working files that will be used later to create the build. The src folder contains folders as:
+
+      - `auth` - config the library for authentication and authorization;
+
+      - `db` - contains such folders as:
+
+        - `api` - documentation that is automatically generated by jsdoc or other tools;
+
+        - `migrations` - is a skeleton of the database or all the actions that users do with the database;
+
+        - `models`- what will represent the database for the backend;
+
+        - `seeders` -  the entity that creates the data for the database.
+
+      - `routes` - this folder would contain all the routes that you have created using Express Router and what they do would be exported from a Controller file;
+
+      - `services` - contains such folders as `emails` and `notifications`.   
+    </details> 
+
+  - Database: PostgreSQL
+
+  - app-shel: Core application framework that provides essential infrastructure services
+for the entire application.
+  -----------------------
+### We offer 2 ways how to start the project locally: by running Frontend and Backend or with Docker.
+-----------------------
+
+## To start the project:
+
+### Backend:
+
+> Please change current folder: `cd backend`
+
+#### Install local dependencies:
+`yarn install`
+
+  ------------
+
+#### Adjust local db:
+##### 1.  Install postgres:
+
+MacOS:
+
+`brew install postgres`
+
+    > if you don’t have ‘brew‘ please install it (https://brew.sh) and repeat step `brew install postgres`.
+
+Ubuntu:
+
+`sudo apt update`
+
+`sudo apt install postgresql postgresql-contrib`
+
+##### 2. Create db and admin user:
+Before run and test connection, make sure you have created a database as described in the above configuration. You can use the `psql` command to create a user and database.
+
+`psql postgres --u postgres`
+
+Next, type this command for creating a new user with password then give access for creating the database.
+
+`postgres-# CREATE ROLE admin WITH LOGIN PASSWORD 'admin_pass';`
+
+`postgres-# ALTER ROLE admin CREATEDB;`
+
+Quit `psql` then log in again using the new user that previously created.
+
+`postgres-# \q`
+
+`psql postgres -U admin`
+
+Type this command to creating a new database.
+
+`postgres=> CREATE DATABASE db_{your_project_name};`
+
+Then give that new user privileges to the new database then quit the `psql`.
+
+`postgres=> GRANT ALL PRIVILEGES ON DATABASE db_{your_project_name} TO admin;`
+
+`postgres=> \q`
+
+  ------------
+
+#### Create database:
+`yarn db:create`
+
+#### Start production build:
+`yarn start`
+
+### Frontend:
+
+> Please change current folder: `cd frontend`
+
+## To start the project with Docker:
+### Description:
+
+The project contains the **docker folder** and the `Dockerfile`.
+
+The `Dockerfile` is used to Deploy the project to Google Cloud.
+
+The **docker folder** contains a couple of helper scripts:
+
+- `docker-compose.yml` (all our services: web, backend, db are described here)
+- `start-backend.sh` (starts backend, but only after the database)
+- `wait-for-it.sh` (imported from https://github.com/vishnubob/wait-for-it)
+
+    > To avoid breaking the application, we recommend you don't edit the following files: everything that includes the **docker folder** and `Dokerfile`.
+
+## Run services:
+
+1. Install docker compose (https://docs.docker.com/compose/install/)
+
+2. Move to `docker` folder. All next steps should be done from this folder.
+
+   ``` cd docker ```
+
+3. Make executables from `wait-for-it.sh` and `start-backend.sh`:
+
+   ``` chmod +x start-backend.sh && chmod +x wait-for-it.sh ```
+
+4. Download dependend projects for services.
+
+5. Review the docker-compose.yml file. Make sure that all services have Dockerfiles. Only db service doesn't require a Dockerfile.
+
+6. Make sure you have needed ports (see them in `ports`) available on your local machine.
+
+7. Start services:
+
+   7.1. With an empty database `rm -rf data && docker-compose up`
+
+   7.2. With a stored (from previus runs) database data `docker-compose up`
+
+8. Check http://localhost:3000
+
+9. Stop services:
+
+   9.1. Just press `Ctr+C`
+
+## Most common errors:
+
+1. `connection refused`
+
+   There could be many reasons, but the most common are:
+
+  - The port is not open on the destination machine.
+
+  - The port is open on the destination machine, but its backlog of pending connections is full.
+
+  - A firewall between the client and server is blocking access (also check local firewalls).
+
+   After checking for firewalls and that the port is open, use telnet to connect to the IP/port to test connectivity. This removes any potential issues from your application.
+
+   ***MacOS:***
+
+   If you suspect that your SSH service might be down, you can run this command to find out:
+
+   `sudo service ssh status`
+
+   If the command line returns a status of down, then you’ve likely found the reason behind your connectivity error.
+
+   ***Ubuntu:***
+
+   Sometimes a connection refused error can also indicate that there is an IP address conflict on your network. You can search for possible IP conflicts by running:
+
+   `arp-scan -I eth0 -l | grep <ipaddress>`
+
+   `arp-scan -I eth0 -l | grep <ipaddress>`
+
+   and
+
+   `arping <ipaddress>`
+
+2. `yarn db:create` creates database with the assembled tables (on MacOS with Postgres database)
+
+   The workaround - put the next commands to your Postgres database terminal:
+
+   `DROP SCHEMA public CASCADE;`
+
+   `CREATE SCHEMA public;`
+
+   `GRANT ALL ON SCHEMA public TO postgres;`
+
+   `GRANT ALL ON SCHEMA public TO public;`
+
+   Afterwards, continue to start your project in the backend directory by running:
+
+   `yarn start`

+#### Run App on local machine:
+
+##### Install local dependencies:
+
+- `yarn install`
+
+---
+
+##### Adjust local db:
+
+###### 1. Install postgres:
+
+- MacOS:
+
+  - `brew install postgres`
+
+- Ubuntu:
+  - `sudo apt update`
+  - `sudo apt install postgresql postgresql-contrib`
+
+###### 2. Create db and admin user:
+
+- Before run and test connection, make sure you have created a database as described in the above configuration. You can use the `psql` command to create a user and database.
+
+  - `psql postgres --u postgres`
+
+- Next, type this command for creating a new user with password then give access for creating the database.
+
+  - `postgres-# CREATE ROLE admin WITH LOGIN PASSWORD 'admin_pass';`
+  - `postgres-# ALTER ROLE admin CREATEDB;`
+
+- Quit `psql` then log in again using the new user that previously created.
+
+  - `postgres-# \q`
+  - `psql postgres -U admin`
+
+- Type this command to creating a new database.
+
+  - `postgres=> CREATE DATABASE db_newapp;`
+
+- Then give that new user privileges to the new database then quit the `psql`.
+  - `postgres=> GRANT ALL PRIVILEGES ON DATABASE db_newapp TO admin;`
+  - `postgres=> \q`
+

+
+#### Api Documentation (Swagger)

+http://localhost:8080/api-docs (local host)
+
+http://host_name/api-docs
+
+---
+
+##### Setup database tables or update after schema change
+
+- `yarn db:migrate`
+
+##### Seed the initial data (admin accounts, relevant for the first setup):
+
+- `yarn db:seed`
+
+##### Start build:
