Nexus

A visual API orchestration platform — design API call flows with drag-and-drop.

Tech Stack

• Backend: Java 8 / Spring Boot 2.7 + MyBatis + brief ORM + Aviator (expression engine)
• Frontend: Vue 3 + TypeScript + Element Plus + D3.js
• Database: SQLite (default) / MySQL (optional)
• Cache: Caffeine in-memory (default) / Redis (optional)

Modules

nexus               # 顶层父 POM (packaging=pom),聚合所有子模块
├── server          # 主服务,Spring Boot 应用,端口 9127
├── dag-engine      # DAG 流程编排引擎(库)
└── sample
    └── item-server # 示例 mock item API,端口 8090

所有子模块继承顶层 nexus 父 POM,再由 spring-boot-starter-parent 传递统一版本管理。

Quick Start

Build & Run

# 编译整个 reactor(根目录执行)
mvn clean package -DskipTests

# 运行主服务(默认端口 9127)
java -jar server/target/server-1.0.0.jar

# 开发期也可直接跑
mvn -pl server spring-boot:run

# 构建前端(可选,开发期可单独运行)
cd console-ui && npm install && npm run build

Configuration

主服务配置位于 server/src/main/resources/application.yml:

server:
  port: 9127

spring:
  profiles:
    active: sqlite          # sqlite 或 mysql
  datasource:
    driver-class-name: org.sqlite.JDBC
    url: jdbc:sqlite:./data/nexus.db

nexus:
  database:
    driver: sqlite          # sqlite or mysql
    mysql:
      host: 127.0.0.1
      port: 3306
      database: nexus
      username: root
      password: "123456"
  auth:
    jwt-secret: "www.javaoffers.com####www.nexus.plus"
    jwt-expire: 7200
  cache:
    type: memory            # memory or redis
    redis:
      addr: "127.0.0.1:6379"

Docker

docker compose up --build        # 构建并运行,映射 9127 端口
