[node.js]Insert restaurant information from TabelogAPI to mongoDB

食べログAPI
Pocket

Target

Same as title.
It’s just memo to remember how to use config file (yaml) and write log.

Source code

Libraries which following source code use are written below:

  • cheerio : To analyze xml
  • request : To send request and get response from TabelogAPI
  • yaml : To analyze yaml file (config file)
  • fs : To get config file from file system
  • commander : To analyze command line option
  • mongoose : To treat mongoDB
  • log4js : To write log
#!/usr/bin/env node

/**
 * @description
 *      Get restaurant data from tabelog api and insert data to event.

 */
 
//===============================================
// Load Libraries

var cheerio = require("cheerio");
var request = require("request");
var yaml = require("yaml");
var fs = require("fs");
var command = require("commander");
var mongoose = require("mongoose");
var log4js = require('log4js');

//===============================================
// Logging Setting

log4js.configure({
	appenders: [{
		"type": "dateFile",
		"filename": "./logs/insert_tabelog_datas.log",
		"pattern": "-yyyy-MM-dd"
	}]
});
var logger = log4js.getLogger("dateFile");

//===============================================
// Load config file

var configData = fs.readFileSync("./config/config.yml","utf8");
var config = yaml.eval(configData); 

//===============================================
// Make request URL

var requestBaseUrl = config.tabelog_api.base_url;
var apiKey = config.tabelog_api.api_key;

// paramter
// parse command options and create help command automatically
command
    .version('1.0.0')
    .usage('[option]')
    .option('-p, --prefecture <String>', 'prefecture name (default japan)')
    .option('-n, --pagenum <n>', 'page number (max 60)', parseInt)
    .parse(process.argv);

var pageNumber = 1;
var prefecture = "japan";

queryParams.push("PageNum=" + pageNumber);

// join
var requestUrl = requestBaseUrl + "?" + queryParams.join("&amp;");

//===============================================
// DB setting

        update: { $set: { name: model.collection.name }, $inc: { sequence: 1 } },

        } else {
            next(err || new Error(data.documents[0].errmsg));
        }
    });
});

var Events = db.model("events_tests", EventsSchema);

//===============================================
// Analyze response

logger.info("request url: " + requestUrl);
request({url: requestUrl}, function(error, response, body)
{
	if (!error &amp;&amp; response.statusCode == 200) {
		logger.info("response statusCode : " + response.statusCode);
