Dagger

Alpha, use at your own risk

Dagger is the backend of a minimal web API server for rapidly prototyping super-lightweight node.js services.

Dagger offers:

- The ability to rapidly develop web APIs and flexibly integrate services of all types in minimal time.
- An incredibly tight end product. None of the dependency bloat or slow startup of Express.js
- Predictability, readability and maintainability of its code.

Express and other web frameworks encourage anti-patterns like the Connect-style responder chain, which distributes
portions of the request-parsing and response-generating code into vastly different (sometimes opaque) places in your
source and decreases predictability (and maintainability.) Dagger is totally focused on making the HTTP request-response
paradigm straightforward, even in the most complex cases. Nobody modifies the request or messes with the response but you.

#### Installation

npm install dagger

#### Usage

var server = new Dagger.Server( { "/": homeServer,
"static": staticServer,
"api": new Dagger.Router(
{
"/users": Dagger.APIEndpoint(users.getAll, users),
"/users/:username": Dagger.APIEndpoint(users.getByName, users),
}),
},
8000
);

function getAll(request, response, args, callback)
{
storageLayer.users.all(function(err, users)
{
if(err)
return(callback(undefined, 500)); //return HTTP 500 and no data

if(users.length == 0)
return(callback([], 404)); //return HTTP 404 and an empty list

callback(users); //returning HTTP 200 is the default
});
}

function getByName(request, response, args, callback)
{
storageLayer.users.some({name: args.url.username}, function(err, user)
{
if(err)
return(callback(undefined, 500)); //return HTTP 500 and no data

callback(user);
}
}
