Objx - Go package for dealing with maps, slices, JSON and other data.
|
|
|
|
Overview
|
|
|
|
Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
|
|
a powerful `Get` method (among others) that allows you to easily and quickly get
|
|
access to data within the map, without having to worry too much about type assertions,
|
|
missing data, default values etc.
|
|
|
|
Pattern
|
|
|
|
Objx uses a preditable pattern to make access data from within `map[string]interface{}` easy.
|
|
Call one of the `objx.` functions to create your `objx.Map` to get going:
|
|
|
|
m, err := objx.FromJSON(json)
|
|
|
|
NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
|
|
the rest will be optimistic and try to figure things out without panicking.
|
|
|
|
Use `Get` to access the value you're interested in. You can use dot and array
|
|
notation too:
|
|
|
|
m.Get("places[0].latlng")
|
|
|
|
Once you have sought the `Value` you're interested in, you can use the `Is*` methods to determine its type.
|
|
|
|
if m.Get("code").IsStr() { // Your code... }
|
|
|
|
Or you can just assume the type, and use one of the strong type methods to extract the real value:
|
|
|
|
m.Get("code").Int()
|
|
|
|
If there's no value there (or if it's the wrong type) then a default value will be returned,
|
|
or you can be explicit about the default value.
|
|
|
|
Get("code").Int(-1)
|
|
|
|
If you're dealing with a slice of data as a value, Objx provides many useful methods for iterating,
|
|
manipulating and selecting that data. You can find out more by exploring the index below.
|
|
|
|
Reading data
|
|
|
|
A simple example of how to use Objx:
|
|
|
|
// Use MustFromJSON to make an objx.Map from some JSON
|
|
m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
|
|
|
|
// Get the details
|
|
name := m.Get("name").Str()
|
|
age := m.Get("age").Int()
|
|
|
|
// Get their nickname (or use their name if they don't have one)
|
|
nickname := m.Get("nickname").Str(name)
|
|
|
|
Ranging
|
|
|
|
Since `objx.Map` is a `map[string]interface{}` you can treat it as such.
|
|
For example, to `range` the data, do what you would expect:
|
|
|
|
m := objx.MustFromJSON(json)
|
|
for key, value := range m {
|
|
// Your code...
|
|
}
|
|
