How to loop through newline separated json line by line in JavaScript?

Question

I have a JSON file in my project that looks like this:

{"_id":707860,"name":"Hurzuf","country":"UA","coord":{"lon":34.283333,"lat":44.549999}}
{"_id":519188,"name":"Novinki","country":"RU","coord":{"lon":37.666668,"lat":55.683334}}
{"_id":1283378,"name":"Gorkhā","country":"NP","coord":{"lon":84.633331,"lat":28}}

I'm not sure how to loop through each line to put it in an array. How can I do this?

Answer 1

Split on new lines, join with comma, wrap it with brackets, and parse it.

var str = `{"_id":707860,"name":"Hurzuf","country":"UA","coord":{"lon":34.283333,"lat":44.549999}}
{"_id":519188,"name":"Novinki","country":"RU","coord":{"lon":37.666668,"lat":55.683334}}
{"_id":1283378,"name":"Gorkhā","country":"NP","coord":{"lon":84.633331,"lat":28}}`

var lines = str.split(/\n/);
var wrapped = "[" + lines.join(",") + "]";
var obj = JSON.parse(wrapped);

console.log(obj);

Better solution, fix whatever gives you that format to give you the correct structure to start out with.

Answer 2

What about using map properly?

var myVar = `{"_id":707860,"name":"Hurzuf","country":"UA","coord":{"lon":34.283333,"lat":44.549999}}
{"_id":519188,"name":"Novinki","country":"RU","coord":{"lon":37.666668,"lat":55.683334}}
{"_id":1283378,"name":"Gorkhā","country":"NP","coord":{"lon":84.633331,"lat":28}}`;

var myArray = myVar.split('\n').map(JSON.parse);
console.log(myArray);

Answer 3

Try the following code:

var myVar = `{"_id":707860,"name":"Hurzuf","country":"UA","coord":{"lon":34.283333,"lat":44.549999}}
{"_id":519188,"name":"Novinki","country":"RU","coord":{"lon":37.666668,"lat":55.683334}}
{"_id":1283378,"name":"Gorkhā","country":"NP","coord":{"lon":84.633331,"lat":28}}`;

var myArray = [];
myVar.split('\n').map(function (value) {
  myArray.push(JSON.parse(value));
});
console.log(myArray);
