JSON for Elixir
Elixir implementation (with an Erlang parser) of the JSON specification to RFC 4627. ExJSON generate JSON string from keyword lists and maps and can parse into those structures also.
Installation
Add HTTPoison to your mix.exs
dependencies:
def deps do
[{:exjson, "~> 0.6.0"}]
end
and run $ mix deps.get
.
Generating a JSON string from a keyword list
ExJSON.generate([ key: "some value" ])
#=> "{\"key\":\"some value\"}"
ExJSON.generate([ k: [ 1, 2, 3 ] ])
#=> "{\"k\":[1,2,3]}"
ExJSON.generate([ k1: [ k2: [ k3: "v3" ] ] ])
#=> "{\"k1\":{\"k2\":{\"k3\":\"v3\"}}}"
ExJSON.generate([
image: [
width: 800,
height: 600,
title: "View from 15th Floor",
thumbnail: [
url: "http://www.example.com/image/481989943",
height: 125,
width: 100
],
ids: [ 116, 943, 234, 38793 ]
]
])
#=> "{\"image\":{\"height\":600,\"ids\":[116,943,234,38793],\"thumbnail\":{\"height\":125,\"url\":\"http://www.example.com/image/481989943\",\"width\":100},\"title\":\"View from 15th Floor\",\"width\":800}}"
Generating a JSON string from a map
ExJSON.generate(%{
location: %{
lat: -47.8,
lng: 23.8
},
name: "The name",
phone: "666-6666",
urls: [
"http://example1.org",
"http://example2.org"
]
})
#=> "{\"location\":{\"lat\":-47.8,\"lng\":23.8},\"name\":\"The name\",\"phone\":\"666-6666\",\"urls\":[\"http://example1.org\",\"http://example2.org\"]}"
Parsing JSON string to keyword list
ExJSON.parse(
'{
"key": "value",
"another_key": {
"k1": "v1",
"k2": "v2",
"k3": "v3"
}
}')
#=> [ { "key", "value" }, { "another_key", [ { "k1", "v1" }, { "k2", "v2" }, { "k3", "v3" } ] } ]
ExJSON.parse(
'{
"key": "some value",
"another_key": [ "value1", "another value", "value 3" ],
"nested_key": {
"inside_key": "a value",
"bool_value1": true,
"bool_value2": false,
"nil_value": null
},
"tags": [ "test1", "test2", "test3" ]
}')
#=> [ { "key", "some value" }, { "another_key", [ "value1", "another value", "value 3" ] }, { "nested_key", [ { "inside_key", "a value" }, { "bool_value1", true }, { "bool_value2", false }, { "nil_value", nil } ] }, { "tags", [ "test1", "test2", "test3" ] } ]
Parsing JSON string to map
ExJSON.parse('{
"location": {
"lat": -47.8,
"lng": 23.8
},
"name": "The name",
"phone": "666-6666",
"urls": [
"http://example1.org",
"http://example2.org"
]
}', :to_map)
#=> %{"location" => %{"lat" => -47.8, "lng" => 23.8}, "name" => "The name", "phone" => "666-6666", "urls" => ["http://example1.org", "http://example2.org"]}
