infra v1.0.3

infra

Infrastructure provides simple, middleware-like infrastructure for your application startup.

Installation

npm install infra --save

Usage

Define initializers

1. Initialize the database

   exports.description = "Postgres";
   exports.init = function(container, cb) {
       var pg = require('pg')
       // sanity check, ensure database can be connected
       pg.connect(container.config.postgres, cb);
   };

2. Initialize express

   exports.description = "Express web server";
   exports.init = function(container, cb) {
           var app = require('express')();
           app.use(bodyParser.json());
           // register app with container
           container.app = app;
           cb();
       }
   };

3. Initialize routes

   exports.description = "Express routes";
   exports.init = function(container, cb) {
       var app = container.app;
       app.get('/', function(req, res, next) {
           res.render('index');
       })
       cb();
   };

Use the initializers and start the app

var starter = require("infra")();
var container = {
    config: {
        postgres: "postgres://localhost/dev"
    }
};

starter.use(require("./database"));
starter.use(require("./expressPre"));
starter.use(require("./handlebars"));
starter.use(require("./expressPost"));
starter.use(require("./routes"));
starter.use(require("./processHandlers"));

starter.start(container, function(err) {
    if (err) trow err;
    container.app.listen(3000);
});

Tips

1. Use your own logger

   var infra = require("infrastructure")(log.info.bind(log))
