I'm using module.exports to export list of module. Below is my Models/Message.js
var msgModel = function()
{
var getMsg = function() {
return "Hello World";
}
return{
getMsg : getMsg
}
}
module.exports = msgModel;
Below is my app.js
var msgModel = require('./Models/Message');
console.log(msgModel.getMsg());
It raised me error
console.log(msgModel.getMsg());
^
I can't figure out the problem.
You need to do console.log(msgModel().getMsg());. This is because msgModel is a function. I would suggest rewriting your msgModel like the example below instead to achieve the call you wanted.
var msgModel = {
getMsg: function() {
return "Hello World";
}
};
module.exports = msgModel;
You could do something like this:
var msg = new msgModel();
console.log(msg.getMsg());
You should export a function and invoke it in the main app.js
for example:
app.js
var msgModel = require('./Models/Message');
msgModel();
Message.js
var getMsg = function(){
console.log("Hello World!");
};
module.exports = getMsg;
You could write it this way in order to group more functions:
module.exports = {
getMsg: function() {
return "Hello World";
},
anotherFnc: function () {
...
}
};
then you could use:
var msgModel = require('./Models/Message');
console.log(msgModel.getMsg());
