Split A large JSON into Smaller parts in Javascript/jQuery -


i have file upload functionality in application can not upload json files more 10mb in size. if user uploads file >= 10 mb , app should split smaller json files each less 10mb. also, proper json objects needs maintained in new low-sized files.

is there way in javascript or jquery?

i propose solution without specific library. use bit of modern techniques maybe useful you:

var openfile = function(event, callback) {     // target input     var input = event.target;     // create instance of filereader     var reader = new filereader();     // define handler results     reader.onload = function(e){       var contents = e.target.result;        // use promise maybe make neater       callback(contents);     };     // make sure tell read text     // maybe add validation on input     // correct types     reader.readastext(input.files[0]); };  var getchunks = function(str){     var chunks = [];     // not best @ these things should      // around 1mb max     var chunksize = 1000000;      // while chunk less size indicated goes     // same item of array     while (str) {         if (str.length < chunksize) {             chunks.push(str);             break;         }         else {             chunks.push(str.substr(0, chunksize));             str = str.substr(chunksize);         }     }     return chunks; }  var fileinput = document.queryselector('#jsonupload');  fileinput.addeventlistener('change', function(event){     openfile(event, function(str){         console.log(getchunks(str));     }); });

then read json file from:

<input type='file' accept='*' id="jsonupload">
