Govals

Govals is a go/golang package for validate data, using struct and etc. govals have custom function like validate email, numeric, alpha, alpha numeric, date, time, phone number, and length of int or string, i hope soon i will add more function for validate data.

Example

example how to use govals, you can open folder example

Usage

Run this command go get github.com/fn-code/govals to use this library

• Basic Functions

  this is basic function you can use to validate your data:

  ok, err := govals.Length(1000, 2, 10)
  if err != nil {
      log.Println(err)
  }
  if !ok {
      // bla bla bla
  }
  

• Struct

  in struct you can use govals tag like this:

  Name    string `govals:"len, max=22, min=10"`
  Age     int8   `govals:"len, min=18, max=20"`
  Email   string `govals:"email"`
  Date    string `govals:"date"`
  Times   string `govals:"time"`
  Hoby    string `govals:"alpha"`
  Max     string `govals:"numeric"`
  Text    string `govals:"alphaNumeric"`
  Phone   string `govals:"phone"`
  Address string `govals:"custom, regex=[^(a-zA-Z)]"`
  

  • len, min=10, max=22 validate length of string or int
  • email validate string of email
  • date validate date of string if match, like 09-12-1996 or 09/12/1996
  • time validate time if match, like 12:00:01 or 12:01
  • alphavalidate string if contains alpha character
  • numericvalidate string if contains numeric
  • alphaNumeric validate string if contains alpha numeric character
  • phone validate string if valid phone number format
  • custom validate custom rule, using regexp, you can write your own rule to validate data
