Node Traefik (traefik)

Traefik (pronounced traffic) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy

Use traefik as an npm module for tighter integration with node apps.

Usage

npm install traefik

const traefik = require("traefik")

// Path to YAML/TOML
let service = await traefik.start("/path/to/traefik.yml")

// Static Config Only
service = await traefik.start({
  defaultEntryPoints: ["http"],
  entryPoints: {
    http: {
      address: ":3001",
    },
  },
  "log.level": "DEBUG",
})

// Long Form
service = await traefik.start({
  log: true,
  staticConfig: {
    defaultEntryPoints: ["http"],
    entryPoints: {
      http: {
        address: ":3001",
      },
    },
    // dot notation is also OK!
    "log.level": "DEBUG",
  },
  dynamicConfig: {
    http: {
      routers: {
        someRouter: {
          service: "someService",
          rule: "PathPrefix(`/`)",
        },
      },
      services: {
        someService: {
          "loadBalancer.servers": [{ url: "http://localhost:3000" }],
        },
      },
    },
  },
})
