Nodejs File Read 정규식표현 적용

Nodejs 파일읽고 정규식사용

var fs = require('fs');
var es = require('event-stream');
var url = './data/smartIndoorAPI/'; 

var REGEX = /branchEventList/g;
fs.readdir(url, function (err, files) {
    if (err) throw err; 
    files.forEach(function (file) {
      var cnt = 0;
      var s = fs.createReadStream(url + file)
        .pipe(es.split())
        .pipe(es.mapSync(function (line) {
          if (line.match(REGEX)) cnt++;
        })
          .on('error', function () {
            console.log('Error while reading file :', file);
          })
          .on('end', function () {
            console.log('Read entire file : ', file, cnt)
          })
        );
    }); 
  });
