My own .env reader function.

envread.go

package utils
 
import (
    "fmt"
    "os"
    "strings"
)
 
func ReadENV(key string) (value string) {
    var result string
 
    path, err := os.Getwd()
 
    if err != nil {
        fmt.Println("Error occurred while getting path:", err.Error())
    }
 
    _, ok := strings.CutSuffix(path, "/")
 
    var filepath string
    if ok {
        filepath = path + ".env"
    } else {
        filepath = path + "/" + ".env"
    }
    content, err := os.ReadFile(filepath)
 
    if err != nil {
        fmt.Println("Error occurred while reading file ", filepath, " error: ", err.Error())
    }
 
    lines := strings.Split(string(content[:]), "\n")
 
    for _, line := range lines {
        if strings.Contains(line, key) {
            result = strings.Split(line, fmt.Sprintf("%s=", key))[1]
        }
    }
 
    if strings.Contains(result, `"`) || strings.Contains(result, "'") {
        result = strings.ReplaceAll(result, `"`, "")
        result = strings.ReplaceAll(result, `'`, "")
    }
 
    return result
}
