brototype
Bro, do you even javascript?
Features
You've got a deeply-nested set of objects that may or may not always be there.
We've all seen something like this:
var myURL = app.config.environment.buildURL('dev');
which leads to one of our favorite javascript errors...
error: undefined is not a function
And the solution only makes the code base ugly:
var myURL;
if (app && app.config && app.config.environment && app.config.environment.buildURL) {
myURL = app.config.environment.buildURL('dev');
}
We all hate that, don't we?
So what if you could just type:
var myURL;
if (Bro(app).doYouEven('config.environment.buildURL')) {
myURL = app.config.environment.buildURL('dev');
}
Or better yet, how about:
var myURL;
Bro(app)
.iDontAlways('config.environment.buildURL')
.butWhenIdo(function(buildURL){
myURL = buildURL('dev');
});
Well, now you can!
Features
Testing nested members
if(Bro(object).doYouEven('lift')) {}
Or, just use a callback...
Bro(object)
.doYouEven('property.subproperty', function(subproperty) {
console.log(subproperty);
});
Fetching nested members
// get a value if it exists
var value = Bro(object).iCanHaz('cheezeburger');
// get an array of values for paths that exist
var values = Bro(object).iCanHaz(['cheezeburger', 'money', 'beer']);
Calling nested functions
Bro(object)
.iDontAlways('method')
.butWhenIdo(function(returnVal) {
...
});
Handling exceptions
Bro(object)
.braceYourself('method.name')
.hereComeTheErrors(function(e) {
console.log('error ' + e + ' happened.');
});
Bro-oleans
Bro.TOTALLY // true;
Bro.NOWAY // false;
Check for undefined
if (Bro(someVar).isThatEvenAThing() === Bro.TOTALLY) {
// do stuff
}
Get a sorted list of object keys
var keys = Bro(object).allTheThings();
Extending objects
var obj1 = {foo: 'boo', bar: 'bar'},
obj2 = {foo: 'bar', yes: 'no'};
Bro(obj1).comeAtMe(obj2);
// now obj1.foo == 'bar' and obj1.yes == 'no'
Extending Brototype!
Yes, extend me, Bro!
var plugin = { foo: function() { whatever; }};
Bro.prototype.comeAtMe(plugin);
