This project was generated by Flatlogic Platform.
-
Frontend: Angular
-
Design: Standart Angular App
Frontend Folder Structure
The generated application has the following frontend folder structure:
src
folder which contains your working files that will be used later to create the build. the src folder contains folders as:-
app
- contains the component files in which your application logic and data are defined; -
assets
- contains image and other asset files to be copied as-is when you build your application; -
environments
- contains build configuration options for particular target environments. By default, there is an unnamed standard development environment and a production ("prod") environment.

Backend: NoBackend
Install dependencies via yarn
yarn install
Run development server
`yarn start`
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
.
-
Install docker compose (https://docs.docker.com/compose/install/)
-
Move to
docker
folder. All next steps should be done from this folder.cd docker
-
Make executables from
wait-for-it.sh
andstart-backend.sh
:chmod +x start-backend.sh && chmod +x wait-for-it.sh
-
Download dependend projects for services.
-
Review the docker-compose.yml file. Make sure that all services have Dockerfiles. Only db service doesn't require a Dockerfile.
-
Make sure you have needed ports (see them in
ports
) available on your local machine. -
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
-
Check http://localhost:3000
-
Stop services:
9.1. Just press
Ctr+C
-
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>
-
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
