Brain Up!

This project is a web-application being developed to support people with a deficit in their central auditory skills with or without hearing loss, i.e. users of cochlear implant or hearing aids. Intended to be used by children older than 7 years, adults, elderly subjects; anyone who wants to improve their auditory skills, training their brain to improve the understanding of what is heard. It is projected to contain several series of media exercises, which should be added incrementally. The tool structure and usage is organized as other tools like www.uchi.ru.

Our current version is here : http://brainup.site && http://31.184.253.199/ (test user [email protected] password). Now you as a user can register and start doing exercises.

WHY JOIN OUR PROJECT AS A DEVELOPER?

We use the latest technologies and best practices, so developers will get to know new tools and their usage, obtaining a useful experience. We will review your code, give you advice to improve it and listen to your suggestions. Most importantly being an open source project you can show your work in it to any person interested, proving your development expertise with actual examples of your work flow and code samples in a live application.

WE ARE LOOKING FOR

1. Front-end developers: Ember, Angular.
2. Server-side developers: Kotlin and Java. Components, REST and algorithms.
3. DevOps: Continuous integration and delivery.
4. UX: Creative designers for UX research and prototype testing. Your ideas how to improve user retention are welcome.
5. Paintest: for creation pictures for exercises.

Join us! Learn something new, try your skills, prove yourself, get experience and get ahead!

TOOLS WE USE

• Back-end: KOTLIN + Spring boot. Rest api as integration layer.
• Front-end : TBD - Ember, Angular.
• DB: Postgres13.
• TestContainers for running integration tests.

Development:

Development prerequisites

1. FrontEnd: Install node v12 or above https://nodejs.org/en/download/
2. FrontEnd: Install yarn 1.19 or above https://yarnpkg.com/lang/en/docs/install
3. FrontEnd: In order to make any commit you need Husky dependency be installed (you can use frontend build to get it)
4. BackEnd: Install Docker https://hub.docker.com/search/?type=edition&offering=community
5. BackEnd: Idea

Start Front Angular Part - admin application

Go to location where the project is download for example C:\brn\brn\frontend-angular

📄 See here

Start Front Ember Part - user application

📄 See here

Database running:

1. Install docker to your machine. The project uses postgres 11.5. Documentation Currently for local development we use postgres docker image To install docker use:

• on windows
• on mac
• on ubuntu
• debian
• centos

2.1 To run docker db image use the following command:

• on linux\windows:

docker run --name postgres_dev -d -p 5432:5432 -e POSTGRES_DB=brn -e POSTGRES_PASSWORD=$PG_PASSWORD -e POSTGRES_USER=$PG_USER postgres:13

$PG_PASSWORD and $PG_USER are environment variables and could be replaced directly or added to your operating system. how to add in win10.

2.2 Alternatively, you can just replace the variables by "admin", the default user and password for development:

docker run --name postgres_dev -d -p 5432:5432 -e POSTGRES_DB=brn -e POSTGRES_PASSWORD=admin -e POSTGRES_USER=admin postgres:13

Back end Kotlin Part:

1. Run command 'gradle build' from main project folder to build project with tests.
2. Application.kt is the main class to run application from Idea for example.
3. Get Postman Collection from https://www.postman.com/koylubaevNT/workspace/brainup/collection/2686902-d91ba307-e131-4d4f-a308-0a272e063c95 and environment from https://www.postman.com/koylubaevNT/workspace/brainup/environment/2686902-95b2c495-82a1-4244-83c7-dad7f8efebd7.
4. Make post request from "Firebase" folder "Get Authorization Token" using credentials.
5. Then you can call all other end-points from this Postman collection end-point specification is here: https://github.com/Brain-up/brn/blob/master/api-contract/api.raml

Note that if you are using IntelliJ, you may want to use version 2019.2 and later to avoid issues with new kotlin plugin.

Useful Postman scripts:

• Script to generate month tasks statistic (you can use it with brnlogin request in Test tab)

Deploy Application USING DOCKER COMPOSE:

(back-end part and front-end parts, but it is rather slow. it is better to use GitPod) From console, from project's folder, execute:

docker-compose up --build

Alternatively, use daemon mode (no console output):

docker-compose up --build -d

REST API will be accessible at http://localhost:8081/api/swagger-ui.html

docker useful command:

docker ps -a # for show all containers
docker stop idContainer # for stop running container
docker rm $(docker ps -a -q) # Remove all stopped containers

Development tips:

1. Get a task assigned in JIRA (for epamers) or issue (https://github.com/Brain-up/brn/issues) you choosed and discused it with @ElenaSpb, send your githubnick to her.
2. Create branch from dev with the codename of your task, i.e. EPAMLABSBRN-1.
3. Implement your task, do not forget to write tests. Remember to follow project's coding standards: https://github.com/Brain-up/brn/wiki/Coding-Standards or https://kb.epam.com/display/EPMLABSBRN/Coding+Guidelines .
4. Create pull request with task name and description about what was done.
5. Notify the team in our skype chat and wait for reviews. At least one reviewer is necessary, but more can be added in a case by case basis.
6. The task gets merged by a project maintainer.
7. check that build job on jenkins passes successfully.
8. Before load config files check them with https://orfogrammka.ru/ service.

Code style:

1. Please refer for details to kb resources: https://github.com/Brain-up/brn/wiki/Code-Style or https://kb.epam.com/display/EPMCOSRINT/Code+style
2. Always use Ctrl+Alt+L in IDEA to update code formatting before committing!
3. Use gradlew ktlint command to check code style. If this task fails, the related report with error details can be found in the 'build\reports\ktlint' folder.
4. It is also possible to use gradlew ktlintFormat command to fix code style errors automatically.
5. Please note that if gradlew ktlint task fails, project build will fail also.
6. For api.raml validation, you can use [Api Designer] (https://rawgit.com/mulesoft/api-designer/v0.4.2/dist/index.html).

Kotlin input dto validation:

https://github.com/Brain-up/brn/wiki/Kotlin-request-dto-validation-with-annotations

Flyway scripts naming

use V2yearmonthday_taskNumber for example V220210804_899.

Branches:

Use format 'EPMLABSBRN-# issue description' or 'Merge description'. Issue number must be in range [0-1999]

Sonar:

1. https://sonarcloud.io/code?id=Brain-up_brn our project sonar cloud.
2. To view test coveradge locally
   2.1 use jacoco gradle task locally jacocoTestReport 2.2 command line: gradle jacocoTestReport
3. Pay attention that main local metric would be a little bit different from the one in Sonar cloud.
