[WebApp / Express] 간단한 Node Module 만들기

이번 글에서는 NodeJS의 Express Framework에 대하여 간단한 Node Module을 작성하는 방법을 알아보도록 하자.

방법 1 - 각 Method를 개별적으로 Export

{EXPRESS_APP_PATH}/routes/mymod.js

var name = exports.name = 'GChoi'; var secret = 'gchoi'; exports.lower = function(input) { return input.toLowerCase(); }; exports.upper = function(input) { return input.toUpperCase(); }; exports.get_name = function() { return name; }; exports.get_secret = function() { return secret; };

{EXPRESS_APP_PATH}/routes/test.js

var mymod = require('./mymod.js'); console.log(mymod.name); console.log(mymod.lower("MacBook")); console.log(mymod.upper("Apple")); console.log(mymod.get_name()); console.log(mymod.get_secret());

{EXPRESS_APP_PATH}/routes/app.js

... var test = require('./routes/test'); ...

Part 2 - JSON Format으로 Export

{EXPRESS_APP_PATH}/routes/mymod2.js

var secret = 'MacBook'; module.exports = { name: 'iPhone', lower: function(input) { return input.toLowerCase(); }, upper: function(input) { return input.toUpperCase(); }, get_name: function() { return this.name; }, get_secret: function() { return secret; } };

{EXPRESS_APP_PATH}/routes/test.js

var mymod2 = require('./mymod2.js'); console.log(mymod2.name); console.log(mymod2.lower("MacBook")); console.log(mymod2.upper("Apple")); console.log(mymod2.get_name()); console.log(mymod2.get_secret());

{EXPRESS_APP_PATH}/routes/app.js

... var test = require('./routes/test'); ...
