PeerStreet Hackathon 2020 — Backend

Our main idea was simple: we want to show that it's possible to separate domain model from implementation and maintain this model as the first-class project. We created 3 repos connected:

1. Domain model (Protobuf 3 + Rake task to build Ruby gem and Js/Ts package): 0x000000/team7-domain
2. Front-end (Vue-cli + typescript): Kaciaryna/team7-frontend
3. Back-end (Ruby + grpc): 0x000000/team7-backend

Project Structure

We created a simple server implementing LoanService described here

• server.rb — main entry, we do all setup here.
• services/loan_service.rb — simple implementation of LoanService.
• helpers/data_generator.rb — semi-random generator for initial data: User, Loan and Address models.
• helpers/logger.rb — simple logger for grpc server.
• bin/grpcwebproxy-v0.12.0-* — *nix versions of pre-built binaries for the simple proxy server. This server is only required for web clients.

Setup

1. $ bundle
2. $ ./bin/grpcwebproxy{linux/osx} --allow_all_origins --backend_addr=localhost:10369 --run_tls_server=false --use_websockets --server_http_debug_port=10368 --websocket_ping_interval 5s --server_http_max_read_timeout 86400s &
3. $ ruby server.rb
