logr is an open-source logger and metric service.
Helps you debug and analyze performance of your features.
Get to know your application better with logr.

Look at the demo page

• logs look like in your Terminal
• storing data in ClickHouse
• transport data by WebSocket
• Golang backend
• Vue.js frontend
• Authorization by GitHub

Usage

const { Logr } = require('logr-node-client');

const conf = new Logr({
  udp: ':7776',
  publicKey: 'MCAwDQYJKoZIhvcNAQEBBQADDwAwDAIFAMg7IrMCAwEAAQ==',
  privateKey: 'MC0CAQACBQDIOyKzAgMBAAECBQCHaZwRAgMA0nkCAwDziwIDAL+xAgJMKwICGq0=',
});

const logr = conf.newLogger('hello.log');

logr.info('Hello, Logr!');

Config

bind:
  http: ":7778"
  udp: ":7776"
oauth:
  jwt_secret: "santaclausdoesntexist"
  github:
    client_id: "9bd30997b0ee30997b0ee3"
    client_secret: "1f241d37d910b11f241d37d910b11f241d37d910b1"
    org: "504dev"
clickhouse: "tcp://localhost:9000?database=logr&username=logr&password=logr"
mysql: "logr:logr@tcp(localhost:3306)/logr"

• jwt_secret is random string (using to sign temporary authorization tokens)
• client_id and client_secret is GitHub App keys (optional. set empty, if not sure)
• org is organization restriction (if set, only org members can authorize)
