API Documentation: here

Steps to run this project:

1. Clone project
2. Switch to branch development
3. yarn install
4. Create new file ormconfig.json with the content found in ormconfig.json.example file
5. Install PostgreSQL (or run from docker image, see the section below on Running with docker)
6. Create database bitscreen
7. Create user bitscreen with password bitscreen & grant all privileges
8. Execute sync command: yarn schema:sync
9. Insert entry into provider table with random created & updated timestamps and id = 0 and anonymous value to all other custom columns
10. Run -> export JWT_SECRET=localDev
11. Run server -> yarn start

Detailed steps (with commands) to run this project (Ubuntu 20.04):

1. Clone project
2. Switch to branch development
3. yarn install
4. Create new file ormconfig.json with the content found in ormconfig.json.example file
5. Install PostgreSQL -> https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-20-04
6. Access PostgreSQL -> sudo -u PostgreSQL psql
7. Create database called bitscreen -> create database bitscreen;
8. Create user called bitscreen_api with password bitscreen -> create user bitscreen with encrypted password 'bitscreen';
9. Grant privileges to user on database bitscreen -> grant all privileges on database bitscreen to bitscreen;
10. Execute sync command -> yarn typeorm schema:sync
11. From terminal connect to bitscreen database -> \c bitscreen (or if you aren't already in postgres interface -> sudo -u postgres psql -d bitscreen)
12. Insert entry into provider table with random created & updated timestamps and id = 0 and anonymous value to all other custom columns -> INSERT INTO provider(created, updated, id, "walletAddressHashed", country, "businessName", website, email, "contactPerson", address) VALUES('2021-07-16 10:23:54', '2021-07-16 10:24:54', '0', 'anonymous', 'anonymous', 'anonymous', 'anonymous', 'anonymous', 'anonymous', 'anonymous');
13. Run server -> yarn start

Using TypeORM

• Run yarn typeorm to see a complete list of available commands. examples: schema:sync, schema:log, query [query]

Seeding the db

• Remove "type": "module" from package.json
• Set "module": "CommonJS" in tsconfig.json
• Run yarn seed:config and yarn seed:run

Running in dev mode

• yarn start uses nodemon
• You can run the server using the docker image or using docker-compose up
• When using docker-compose, update the image key to point to a local built image if you want to iterate with docker
• The fastest way to iterate in dev mode:
  • Run the postgres db in docker (use docker-compose but comment out the bitscreen-api: part) or use the system postgres db instance
  • Run the server in terminal using yarn start but don't forget to run yarn schema:sync the first time and everytime there is a change to the schema under src/entity

Running with docker

Using docker-compose will start the postgres database and the bitscreen server

docker-compose up

The above will use the bitscreen server (bitscreen-backend) latest docker image (murmurationlabs/bitscreen-backend). You can build local image like this: docker build -t murmurationlabs/bitscreen-backend:local . Use a different tag if you don't want it to overwrite the latest tag

To connect directly to the db we just started

psql -h localhost -p 5432 -d bitscreen -U bitscreen
# then type the password bitscreen 
# now you should be in the plsql `bitscreen=#` prompt so you can issue commands

Production deployment

The main deployment is in EKS:

• Uses the docker image murmurationlabs/bitscreen-backend:latest hosted in docker hub This docker image is updated in docker hub on every push to the master branch
• Postgres database is deployed using bitnami helm chart

Notes

• All node.js commands use the options --experimental-modules --es-module-specifier-resolution=node --loader ts-node/esm to allow running typeorm with the current version of typescript
