Controllers

A controller is a function, which when executed, returns a function that will handle the incoming request and generate the outgoing response:

module.exports = function() {
	return (req, res, next) => {
		res.json({ hello : "world" });
		next();
	};
};

Controllers have access to numerous injected services, including:

• authClientProvider
• environmentService
• idmService
• integrationService
• rulesetService
• serviceProvider
• storageService
• locationService
• blobService

Each of these are defined upon the controller instance as a property that can be access, for example:

module.exports = function() {
	return (req, res, next) => {
		this.storageService.getList("books", 1, 10).then((results) => {
			res.json(results);
			next();
		}).catch((err) => {
			res.json({
				error : err.toString()
			});
			next();
		});
	};
};
