node.js - How to get data row by row from a xlsx file in nodejs -


i facing issue need data xl file , convert record or row json format , send server issue here file gets changed frequently(mean new data added data appended new rows) every change need send added data server have come logic make note of last row have send server , when there change previous variable stores last row sent send rows variable last row .

so want know there way make refernce xlsx file rather loading whole file , getting row row data

mycode doesnt work way:

var fs = require('fs'); var xls= require('xlsx');  var book = xls.readfile('test.xlsx');  var sheet_name_list = book.sheetnames[0]; var sheet1 = book.sheets[sheet_name_list]; //console.log(sheet1);   var j = xls.utils.sheet_to_json(sheet1['a17']); console.log(j);

what want observe file changes, node.js has [fs.watch][1] method this

observe file changes node.js

you need reread file every time change event.

also can try use excel-js package , reading xlsx via stream, i'm not sure send updates while adding rows

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
