Logging

Manage logging.

Overview

By default, logs will be flushed to stdout. User can configure logs to multiple channels.

Install

$ go get github.com/rookie-ninja/rk-boot/v2
$ go get github.com/rookie-ninja/rk-gin/v2
$ go get github.com/rookie-ninja/rk-db/postgres

Log level

By default, the log level is warn which prints with error.

Supported log levels are:

• info
• warn
• error
• silent

1.Create boot.yaml

---
gin:
  - name: user-service
    port: 8080
    enabled: true
postgres:
  - name: demo-db
    enabled: true
    addr: "localhost:5432"
    user: postgres              # Optional, default: postgres
    pass: pass                  # Optional, default: pass
    logger:
      level: info               # Set log level to info
    database:
      - name: demo
        autoCreate: true

2.Create main.go

package main

import (
    "context"
    "github.com/rookie-ninja/rk-boot/v2"
    "github.com/rookie-ninja/rk-db/postgres"
    "gorm.io/gorm"
    "time"
)

func main() {
    boot := rkboot.NewBoot()

    boot.Bootstrap(context.TODO())

    // Auto migrate database and init global userDb variable
    pgEntry := rkpostgres.GetPostgresEntry("demo-db")
    userDb := pgEntry.GetDB("demo")

    if !userDb.DryRun {
        userDb.AutoMigrate(&User{})
    }

    boot.WaitForShutdownSig(context.TODO())
}

// *************************************
// *************** Model ***************
// *************************************

type Base struct {
    CreatedAt time.Time      `yaml:"-" json:"-"`
    UpdatedAt time.Time      `yaml:"-" json:"-"`
    DeletedAt gorm.DeletedAt `yaml:"-" json:"-" gorm:"index"`
}

type User struct {
    Base
    Id   int    `yaml:"id" json:"id" gorm:"primaryKey"`
    Name string `yaml:"name" json:"name"`
}

Output

...
2022-09-19T00:42:46.790+0800    INFO    postgres@v1.3.6/migrator.go:250    [1.337ms] [rows:-] SELECT DATABASE()
2022-09-19T00:42:46.794+0800    INFO    postgres@v1.3.6/migrator.go:253    [3.696ms] [rows:1] SELECT SCHEMA_NAME from Information_schema.SCHEMATA where SCHEMA_NAME LIKE 'demo%' ORDER BY SCHEMA_NAME='demo' DESC,SCHEMA_NAME limit 1
...

Output paths

By default, the log output path is stdout.

1.Create boot.yaml

---
gin:
  - name: user-service
    port: 8080
    enabled: true
postgres:
  - name: demo-db
    enabled: true
    addr: "localhost:5432"
    user: postgres
    pass: pass
    logger:
      level: info
      outputPaths: [ "log/db.log" ]

2.Validate
