## Atlas Fractional
#### example diagram to talk about gateway and other micro services
Atlas Fractional
================
Lerna monorepo that holds common platform code and all packages
## Getting Started
Install dependencies
```
npm ci
npm run bootstrap
```
Build
```
npm run build
```
### Setting up the whole platform Locally
This platform contains all these components
- User Manegement service
- Home Manager service
- Gateway Service
- Home Manager Service
- File Manager Service
- Notification Manager
### Running all these services
> we are using docker-compose to bootstrap all container only (database containers)
> in the root of the project run
```
git clone https://github.com/MobileLeapLabs/atlas-fractional.git
cd atlas-fractional
docker-compose up
➜ atlas-fractional git:(intergrations-and-notifications) docker-compose up
atlas-fractional_postgres-notification-manager_1 is up-to-date
atlas-fractional_postgres-auth_1 is up-to-date
atlas-fractional_postgres-home-manager_1 is up-to-date
atlas-fractional_postgres-file-manager_1 is up-to-date
atlas-fractional_postgres-booking-manager_1 is up-to-date
Attaching to atlas-fractional_postgres-notification-manager_1, atlas-fractional_postgres-auth_1, atlas-fractional_postgres-home-manager_1, atlas-fractional_postgres-file-manager_1, atlas-fractional_postgres-booking-manager_1
```
Note: make sure docker-utils script should have 777 permission on local to get executed
> check the logs and make sure databases has been created
```
as example ::
postgres-notification-manager_1 | server started
postgres-notification-manager_1 | CREATE DATABASE
postgres-notification-manager_1 |
postgres-notification-manager_1 |
postgres-notification-manager_1 | /usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/postgres-database.sh
postgres-notification-manager_1 | Multiple database creation requested: "notification-manager-api","notification-manager-api-testing"
postgres-notification-manager_1 | Creating user and database '"notification-manager-api"'
postgres-notification-manager_1 | CREATE ROLE
postgres-notification-manager_1 | CREATE DATABASE
postgres-notification-manager_1 | GRANT
postgres-notification-manager_1 | Creating user and database '"notification-manager-api-testing"'
postgres-notification-manager_1 | CREATE ROLE
postgres-notification-manager_1 | CREATE DATABASE
postgres-notification-manager_1 | GRANT
postgres-notification-manager_1 | Multiple databases created
```
All services follow same pattern for running locally, now we just need to populate .env and run `npm run start:dev` command
### Running Auth service
```sh
cd auth-service
vi .env
```
Note: You cna take reference from Heroku App setting to know any missing env variables
update env with this content
```
DATABASE_URL= postgres://api:development_pass@localhost:5431/auth-api
SENDGRID_API_KEY=23456754324567854324567
SENDGRID_VERIFIED_SENDER_EMAIL=ack@gmail.com
DEBUG="qapi:*"
LOG_LEVEL=http
PORT=5006
NODE_ENV=local
JWT_SECRET=HELLODEMO
JWT_EXPIRE_IN=3600*24
NOTIFICATION_API_URL=https://notification-manager-api-dev.herokuapp.com/api/v1
```
Now run application in watch mode it will be live on localhost:5006
```sh
npm run start:dev
```
### Running Home Manager
```sh
cd home-manager
vi .env
```
update env with this content
```
NODE_ENV=local
LOG_LEVEL=http
PORT=5003
SECRET_KEY=HELLODEMO
NEW_RELIC_KEY=
DATABASE_URL=postgres://api:development_pass@localhost:5433/home-manager-api
NODE_ENV=local
JWT_SECRET=HELLODEMO
JWT_EXPIRE_IN=3600*24
```
Now run application in watch mode it will be live on localhost:5003
```sh
npm run start:dev
```
### Running Booking Manager
```sh
cd booking-manager
vi .env
```
update env with this content
```
NODE_ENV=local
LOG_LEVEL=http
PORT=5004
JWT_SECRET=HELLODEMO
JWT_EXPIRE_IN=3600*24
DATABASE_URL=postgres://api:development_pass@localhost:5434/booking-manager-api
```
Now run application in watch mode it will be live on localhost:5004
```sh
npm run start:dev
```
### Running File Manager
```sh
cd file-manager
vi .env
```
update env with this content
```
NODE_ENV=local
LOG_LEVEL=http
PORT=5009
DATABASE_URL=postgres://api:development_pass@localhost:5439/file-manager-api
NODE_ENV=local
JWT_SECRET=HELLODEMO
JWT_EXPIRE_IN=3600*24
AWS_BUCKET_NAME=atlas-fractional-home-ownership
AWS_ACCESS_KEY=AKIAZGLBBDEH7JMRHCWI
AWS_SECRET_ACCESS=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
AWS_REGION=us-east-1
```
Now run application in watch mode it will be live on localhost:5009
```sh
npm run start:dev
```
### Running Notification Manager
```sh
cd notification-manager
vi .env
```
update env with this content
```
NODE_ENV=local
PORT=3010
AUTH_PROVIDER=auth0
AUTH_SECRET=HELLODEMO
DATABASE_URL= postgres://api:development_pass@localhost:5435/notification-manager-api
ROLLBAR_TOKEN=
NEW_RELIC_LICENSE_KEY=
LOG_LEVEL=http
SWAGGER_USERNAME=money-moves
SWAGGER_PASSWORD=money-moves
SENDGRID_USER=hello
SENDGRID_PASSWORD=hello
```
Now run application in watch mode it will be live on localhost:5010
```sh
npm run start:dev
```
### Running Gateway Service
```sh
cd gateway-service
vi .env
```
update env with this content
```
NODE_ENV=local
LOG_LEVEL=info
PORT=5002
NEW_RELIC_KEY=
SECRET_KEY=HELLODEMO
HOME_MANAGER_API=http://localhost:5003/graphql
AUTH_API=http://localhost:5006/graphql
BOOKING_MANAGER_API=http://localhost:5004/graphql
FILE_MANAGER_API=http://localhost:5009/graphql
```
Now run application in watch mode it will be live on localhost:5002
```sh
npm run start:dev
```
Once all services are up we can use gateway service to connect with all apis
```sh
http://localhost:5002/graphql
```
