Servify

Microservices the simplest way conceivable.

Usage

Create a microservice:

const servify = require("servify");
 
// The service state
let count = 0;
 
// Starts a microservice with 3 API methods
servify.api(3000, {
 
    // Squares a number
    square: (x) => x * x,
 
    // Concats two arrays
    concat: (a, b) => a.concat(b),
 
    // Increments and returns the counter
    count: () => count++
 
}).then(() => console.log("servified port 3000"))

Call a microservice from code:

const servify = require("servify");
 
// Builds the API interface from an URL
const api = servify.at("http://localhost:3000");
 
// Calls API methods like normal lib functions
api.square(2)
    .then(x => console.log(x));
 
api.concat([1,2], [3,4])
    .then(arr => console.log(arr));
 
api.count()
    .then(i => console.log(i));

Call a microservice from the browser / request:

Just access the url followed by a function call:
 
http://localhost:3000/square(2)
http://localhost:3000/concat([1,2], [3,4])
http://localhost:3000/count()

Support

This requires ES6 Proxy support, so you need node.js 6 and up. Proxies cannot be polyfilled in earlier versions.

Why

When all you want is to create a microservice, Express.js becomes annoyingly verbose. You have to worry about things like serializing/deserializing JSON, chosing how to format query/param inputs, picking a XHR lib on the client and so on. Servify is a ridiculously thin (50 LOC) lib that just standardizes that boring stuff. To create a microservice, all you need is an object of functions specifying your API. To interact with a service, all you need is its URL. You can then call its functions exactly like you would call a normal lib (except it returns a Promise, obviously).
