MiniFigures

A collection of graphs, which uses gRPC for communication, Rust (Tonic) for the backend server and React (protobuf-ts) for the frontend.

Tech stack:

• Backend:

  • Prost: Protobuf

  • Tonic: gRPC server

  • Tokio: Async runtime

• Frontend:

  • Vite: Frontend tooling

  • React: User interfaces

  • Protobuf-ts: Protobuf

  • Antd: UI components

  • ECharts: Visualization library

Quick Start

1. Copy your own CSV data into the ./data directory, see Data for the required schema.

2. Run data server by make dev-srv

3. Define your own ./viz/.env file (see ./viz/.template.env)

4. Run web server by make init-dev-viz

Structure

Backend - Srv

Dependencies for gRPC:

cargo add prost prost-types tonic tonic-web

Test case:

grpcurl -plaintext -import-path proto -proto kbar.proto 127.0.0.1:8001 kbar.KBar/GetSymbols
grpcurl -d '{"symbol": "000001.SH"}' -plaintext -import-path proto -proto kbar.proto 127.0.0.1:8001 kbar.KBar/GetKBar

Frontend - Viz

Dependencies for gRPC:

yarn add @protobuf-ts/plugin @protobuf-ts/grpcweb-transport

Use case please see protobuf-ts

Data

• kbar: proto file defined in here, and one must provide a CSV file (under ./data dir) with head:

  symbol,trade_date,pre_close,open_price,hight_price,low_price,close_price,change,pct_change,volume,amount
