Node.js module for generating response payloads for server requests to ensure uniform responses

$ npm install @lingua/response-payload

Usage

const ResponsePayload = require('@lingua/response-payload');

http.createServer((req, res) => {
	const response = new ResponsePayload(req, res);

	try {
		doSomething();
		response.setPayload({ message: 'Hi' });
		res.writeHead(200, {'content-type': 'application/json'});
	}
	catch (err) {
		response.addError(err).captureStacktrace(err);
		res.writeHead(500, {'content-type': 'application/json'});
	}

	res.end(JSON.stringify(response));
});

Example response:

{
	"url": "http://example.com/",
	"timestamp": "2016-12-29T06:35:55.029Z",
	"errors": [
		"Something went wrong"
	],
	"payload": {
		"message": "Hi"
	},
	"stacktrace": [
		"at repl:1:2",
		"at realRunInThisContextScript (vm.js:22:35)",
		"at sigintHandlersWrap (vm.js:98:12)",
		"at ContextifyScript.Script.runInThisContext (vm.js:24:12)",
		"at REPLServer.defaultEval (repl.js:346:29)",
		"at bound (domain.js:280:14)",
		"at REPLServer.runBound [as eval] (domain.js:293:12)",
		"at REPLServer.onLine (repl.js:545:10)",
		"at emitOne (events.js:101:20)",
		"at REPLServer.emit (events.js:188:7)"
	]
}

Config:

ResponsePayload.config = {
	// Should a stacktrace be included in the response
	includeStacktrace: false,

	// Should included stacktraces be parsed out (requires the @lingua/debug-stack optional dependency)
	parseStacktrace: false
};
