Package config provides convenient access methods to configuration stored as JSON. This is a simplified library from this
Example JSON configuration:
{
"development": {
"database": {
"host":"localhost",
"username":"root",
"password":"12345",
"port":12345,
"name":"dev"
}
},
"production": {
"database":{
"host":"localhost",
"username":"root",
"password":"12345",
"port":12345,
"name":"dev"
}
}
}We can load the JSON configuration file by using:
cfg, err := Load("/path/to/config.json")
if err != nil {
panic(err)
}And we can change root path by using:
// Get development environment configuration
cfg, err = cfg.Get("development")
if err != nil {
panic(err)
}Get configuration value by using:
// Get database host or return empty string if not exists
host := cfg.UString("database.host")
// Get database host or return default passed value if not exists
host := cfg.UString("database.host", "default")
// Get database host and error
host, err := cfg.String("database.host")These are all method to get configuration value:
// Load reads a JSON configuration from given filename
func Load
// Get returns a nested config according to a dotted path.
func (*Config) Get
// Return single value or default
func (*Config) UBool
func (*Config) UFloat64
func (*Config) UInt
func (*Config) UList
func (*Config) UMap
func (*Config) UString
// Return value and error
func (*Config) Bool
func (*Config) Float64
func (*Config) Int
func (*Config) List
func (*Config) Map
func (*Config) StringSee documentation in GoDoc for more detail
