JSON-Lean
Extract/Merge key and value trees from a JSON.
It is useful if you make multiple requests and the response object has the same structure. You can respond only with the data.
Example
Input:
{
"array": [
1,
2,
3
],
"boolean": false,
"integer": 1042,
"float": 10.5,
"largeNumber": 15000000000,
"exponent": 162e3,
"exponentString": "162e+5",
"decimalFraction": 0.00000000001,
"exponentFraction": 1e-7,
"numberString": "123e+10",
"object": {
"name": "Oscar"
},
"string": "I love deadlines. I like the whooshing sound they make as they fly by."
}Output:
[
// Keys, sorted
[
"array",
"boolean",
"decimalFraction",
"exponent",
"exponentFraction",
"exponentString",
"float",
"integer",
"largeNumber",
"numberString",
{
"object": [
"name"
]
},
"string"
],
// Values, in corresponding order
// Send only this in your server responses
[
[
1,
2,
3
],
// Boolean converted to integer
0,
1e-11,
// JSON.parse() automatically converts 162e3 to integer :(
162000,
1e-7,
"162e+5",
10.5,
1042,
// largeNumber is shorter in Exponential Notation
"1.5e+10",
"123e+10",
[
"Oscar"
],
"I love deadlines. I like the whooshing sound they make as they fly by."
