Exploring the combination of Coffeescript and AngularJS for the first time.
Attempting to create a new service in AngularJS with a dependency on the $http service.
The desired code structure is as follows:
var MyService = function($http) {
this.$http = $http;
};
MyService.prototype.call = function(url, data) {
this.$http(url, data);
};
myApp.service("webService", MyService)
This is the standard way of registering a service according to the AngularJS documentation.
Following an article on using Coffeescript with AngularJS, I tried the following approach:
myApp.service "webService", class
constructor : (@$http) ->
call : (url, data) -> @$http url, data
However, the compiled Javascript output presents a different scenario:
myApp.service("webService", (function() {
function _Class(_at_$http) {
this.$http = _at_$http;
}
_Class.prototype.call = function(url, data) {
return this.$http(url, data);
};
return _Class;
})());
The issue lies in the Coffeescript compiler replacing @$http with _at_$http. The expected Javascript output should be:
myApp.service("webService", (function() {
function _Class($http) {
this.$http = $http;
}
_Class.prototype.call = function(url, data) {
return this.$http(url, data);
};
return _Class;
})());
An online Coffeescript compiler demonstrates the correct result, highlighting the discrepancy in the compilation process.
It is crucial to resolve this issue as Angular's injection engine necessitates the parameter name to be recognized as $http.
