Functions ¶
func Do ¶
Do takes a nested map and flattens it into a single level map. The flattening follows the JSONPath standard. Please see the example to understand how the flattened output looks like.
Example ¶
package main
import (
"encoding/json"
"fmt"
"github.com/nextmv-io/sdk/flatmap"
)
func main() {
nested := map[string]any{
"a": "foo",
"b": []any{
map[string]any{
"c": "bar",
"d": []any{
map[string]any{
"e": 2,
},
true,
},
},
map[string]any{
"c": "baz",
"d": []any{
map[string]any{
"e": 3,
},
false,
},
},
},
}
flattened := flatmap.Do(nested)
b, err := json.MarshalIndent(flattened, "", " ")
if err != nil {
panic(err)
}
fmt.Println(string(b))
}
Output: { "$.a": "foo", "$.b[0].c": "bar", "$.b[0].d[0].e": 2, "$.b[0].d[1]": true, "$.b[1].c": "baz", "$.b[1].d[0].e": 3, "$.b[1].d[1]": false }
func Undo ¶
Undo takes a flattened map and nests it into a multi-level map. The flattened map should follow the JSONPath standard. Please see the example to understand how the nested output looks like.
Example ¶
package main
import (
"encoding/json"
"fmt"
"github.com/nextmv-io/sdk/flatmap"
)
func main() {
flattened := map[string]any{
"$.a": "foo",
"$.b[0].c": "bar",
"$.b[0].d[0].e": 2,
"$.b[0].d[1]": true,
"$.b[1].c": "baz",
"$.b[1].d[0].e": 3,
"$.b[1].d[1]": false,
}
nested, err := flatmap.Undo(flattened)
if err != nil {
panic(err)
}
b, err := json.MarshalIndent(nested, "", " ")
if err != nil {
panic(err)
}
fmt.Println(string(b))
}
Output: { "a": "foo", "b": [ { "c": "bar", "d": [ { "e": 2 }, true ] }, { "c": "baz", "d": [ { "e": 3 }, false ] } ] }
