spur-web

Common node modules and express middleware that are designed to be the boilerplate of a node web app.

About the Spur Framework

The Spur Framework is a collection of commonly used Node.JS libraries used to create common application types with shared libraries.

Quick start

Installing

Dependencies:

$ npm install --save spur-ioc spur-common spur-config

Module:

$ npm install --save spur-web

Note: The example code below expects that you are using Node 6. We follow the active Node LTS schedule.

Usage

src/config/*

For an example of the configuration, please take a look at this example: example/src/config/.

src/injector.js

const path = require('path');
const spur = require('spur-ioc');
const spurCommon = require('spur-common');
const registerConfig = require('spur-common/registerConfig');
const spurWeb = require('spur-web');

module.exports = function () {
  const ioc = spur.create('example');

  // Register configuration
  registerConfig(ioc, path.join(__dirname, './config'));

  ioc.merge(spurCommon());
  ioc.merge(spurWeb());

  // register folders in your project to be auto-injected
  ioc.registerFolders(__dirname, [
    'controllers/',
    'runtime/'
  ]);

  return ioc;
};

src/runtime/WebServer.js

module.exports = function (BaseWebServer, path) {
  class WebServer extends BaseWebServer {

    // Add additional changes to the middleware by overriding the method
    registerDefaultMiddleware() {
      super.registerDefaultMiddleware();
    }
  }

  // Assure there is just one instance
  return new WebServer();
};

src/controllers/HelloController.js

Files ending in *Controller.js are auto registered as controllers.

module.exports = function (BaseController) {
  class HelloController extends BaseController {

    configure(app) {
      super.configure(app);

      app.get('/', this.getRoot.bind(this));
      app.get('/hello', this.getHello.bind(this));
    }

    getRoot(req, res) {
      res.status(200).send('This is the root page defined in HelloController.js.');
    }

    getHello(req, res) {
      res.send('hello');
    }
  }

  return new HelloController();
};

start.js

const injector = require('./src/injector');

// IMPORTANT: The callback needs to be a function call vs. using a fat-arrow block. Fat-arrow is not supported yet.
injector().inject(function (UncaughtHandler, WebServer, Logger, config, configLoader, nodeProcess) {
  UncaughtHandler.listen();

  Logger.info(`NODE_ENV: ${nodeProcess.env.NODE_ENV}`);
  Logger.info(`PORT: ${config.Port}`);
  Logger.info(`CONFIG: ${configLoader.configName}`);

  WebServer.start()
    .then(() => {
      // Execute other logic after the server has started
    });
});

Running example

$ npm start

Available dependencies in injector

To see the latest list of the default dependencies that are injected, check out the injector.js file. Here is a short list of of all of the dependencies available:

Libraries

List of external dependencies used and exposed by spur-web. They can be found at npmjs.org using their original names.

Name	Original Module Name
express	express
expressDevice	express-device
methodOverride	method-override
cookieParser	cookie-parser

expressWinston	express-winston

Local dependencies

All of the files under the src/ directory are made available when this module is merged into another injector. The following list are the notable dependencies available.

Reusable

Name	Source	Description
BaseController	code	A base class in order to be able to identify all of the controllers derived from it.
BaseWebServer	code	A base web server that sets all of the middleware mentioned here.
ControllerRegistration	code	Registers all of the controllers based on the BaseController type and also files that end with Controller
BaseMiddleware	code	A base class in order to be able to identify all of the middleware derived from it.

Used internally, but can be used/replaced

Name	Source	Description
HtmlErrorRender	code	Sets basic error rendering for uncaught errors.
DefaultMiddleware	code	Registers default express middleware: cookie parser, and body parser
ErrorMiddleware	code	Adds error handling for unhandled errors for requests.
NoCacheMiddleware	code	Middleware for no cache headers
PromiseMiddleware	code	Extends the response object with functionality to be used through promises. It unwraps promises as they are being resolved.
WinstonRequestLoggingMiddleware	code	Winston middleware for logging every request to the console log.
