在nodejs中读取大文本文件时遇到问题的处理方案

FATAL ERROR: CALL_AND_RETRY_0 Allocation failed - process out of memory

以下解决方案允许您流式传输文件而不是将其全部读入内存：

var fs = require('fs');
var readline = require('readline');
var stream = require('stream');
var instream = fs.createReadStream('your/file');
var outstream = new stream;
var rl = readline.createInterface(instream, outstream);
rl.on('line', function(line) {
  // process line here
});
rl.on('close', function() {
  // do something on finish here
});
