在node.js中一次读取一行文件？ 25个答案

---

var fs = require('fs');
var readline = require('readline');
var stream = require('stream');

var instream = fs.createReadStream('./test.txt');
var outstream = new stream;
var rl = readline.createInterface(instream, outstream);

var arr = [];

rl.on('line', function(line) {
  // process line here
  arr.push(line);
});

rl.on('close', function() {
  // do something on finish here
  console.log('arr', arr);
});

这种方法也处理大文本文件。 https://coderwall.com/p/ohjerg/read-large-text-files-in-nodejs

看看这个答案。

这是在那里提出的解决方案：

var lineReader = require('readline').createInterface({
  input: require('fs').createReadStream('file.in')
});

lineReader.on('line', function (line) {
  console.log('Line from file:', line);
});

也已添加到节点文档。
