restify-await-promise

Converts restify routes to support async/await and returned promises. Works with Restify 4.x through 6.x. May work with Restify 7+.

#Supported Restify Versions

• Fully Supported
  • 4.x to 5.x
• Probably Works
  • 6.x
• Partially Compatible
  • 7.x+

Usage

const restify = require('restify');
const restifyPromise = require('restify-await-promise');

const server = restify.createServer({
  name: 'myapp',
  version: '1.0.0'
});

//Allows you to manipulate the errors before restify does its work
const alwaysBlameTheUserErrorTransformer = {
	transform: function( exceptionThrownByRoute ){
		//Always blame the user
		exceptionThrownByRoute.statusCode = 400; 
		return exceptionThrownByRoute;
	}
}

const options = {
	logger: yourLogger,                                  //Optional: Will automatically log exceptions	
	errorTransformer: alwaysBlameTheUserErrorTransformer //Optional: Lets you add status codes 
};

restifyPromise.install( server, options ); // Options is not required

// Async function, automatically calls send with the returned object and next
server.get('/lookup/:name', async function (req) {
	return await SomePromise.work( req.parms.name );
});

// Promise function
server.get('/echo/:name', function (req) {
	const params = req.params; 
	return Promise.resolve( { params } );
});

// Existing restify method
server.get('/echo2/:name', function (req, res, next) {
	  res.send(req.params);
	  next();
});

// Versioned Route with Restify 7+
server.get('/seek/:enlightenment', restifyPromise.asyncConditionalHandler([	
	{
		version: "1.0.0",
		handler: async function (req) {
			const result = await searchFor( req.parms.enlightenment );
			return result;
		}
	}
]));

server.listen(8080, function () {
	  console.log('%s listening at %s', server.name, server.url);
});
