i18n

Usage

Download and install it:

go get github.com/gin-contrib/i18n

Import it in your code:

import ginI18n "github.com/gin-contrib/i18n"

Canonical example:

package main

import (
  "log"
  "net/http"

  ginI18n "github.com/gin-contrib/i18n"
  "github.com/gin-gonic/gin"
  "github.com/nicksnyder/go-i18n/v2/i18n"
)

func main() {
  // new gin engine
  gin.SetMode(gin.ReleaseMode)
  router := gin.New()

  ginI18n.Localize()

  router.GET("/", func(context *gin.Context) {
    context.String(http.StatusOK, ginI18n.MustGetMessage("welcome"))
  })

  router.GET("/:name", func(context *gin.Context) {
    context.String(http.StatusOK, ginI18n.MustGetMessage(&i18n.LocalizeConfig{
      MessageID: "welcomeWithName",
      TemplateData: map[string]string{
        "name": context.Param("name"),
      },
    }))
  })

  if err := router.Run(":8080"); err != nil {
    log.Fatal(err)
  }
}

Customized Bundle

package main

import (
  "encoding/json"
  "log"
  "net/http"

  ginI18n "github.com/gin-contrib/i18n"
  "github.com/gin-gonic/gin"
  "github.com/nicksnyder/go-i18n/v2/i18n"
  "golang.org/x/text/language"
)

func main() {
  // new gin engine
  gin.SetMode(gin.ReleaseMode)
  router := gin.New()

  // init
  ginI18n.Localize(ginI18n.WithBundle(&ginI18n.BundleCfg{
    RootPath:         "./_example/localizeJSON",
    AcceptLanguage:   []language.Tag{language.German, language.English},
    DefaultLanguage:  language.English,
    UnmarshalFunc:    json.Unmarshal,
    FormatBundleFile: "json",
  }))

  router.GET("/", func(context *gin.Context) {
    context.String(http.StatusOK, ginI18n.MustGetMessage("welcome"))
  })

  router.GET("/:name", func(context *gin.Context) {
    context.String(http.StatusOK, ginI18n.MustGetMessage(&i18n.LocalizeConfig{
      MessageID: "welcomeWithName",
      TemplateData: map[string]string{
        "name": context.Param("name"),
      },
    }))
  })

  if err := router.Run(":8080"); err != nil {
    log.Fatal(err)
  }
}

Customized Get Language Handler

package main

import (
  "log"
  "net/http"

  ginI18n "github.com/gin-contrib/i18n"
  "github.com/gin-gonic/gin"
  "github.com/nicksnyder/go-i18n/v2/i18n"
)

func main() {
  // new gin engine
  gin.SetMode(gin.ReleaseMode)
  router := gin.New()

  // init
  ginI18n.Localize(
    ginI18n.WithGetLngHandle(
      func(context *gin.Context, defaultLng string) string {
        lng := context.Query("lng")
        if lng == "" {
          return defaultLng
        }
        return lng
      },
    ),
  )

  router.GET("/", func(context *gin.Context) {
    context.String(http.StatusOK, ginI18n.MustGetMessage("welcome"))
  })

  router.GET("/:name", func(context *gin.Context) {
    context.String(http.StatusOK, ginI18n.MustGetMessage(&i18n.LocalizeConfig{
      MessageID: "welcomeWithName",
      TemplateData: map[string]string{
        "name": context.Param("name"),
      },
    }))
  })

  if err := router.Run(":8080"); err != nil {
    log.Fatal(err)
  }
}
