jazzy - a framework that makes your apps swing

Disclaimer: Jazzy is in early beta stage, documentation is non-existent, you want to look at other, more popular choices.

Jazzy attempts to leverage your existing node skills and best choice of modules.

Logging

As of now Jazzy provides Logger objects.

    var logger = new Logger("/var/log/daemon/%Y/%m/%d.log");

    logger.mangler(function(log) {
        if (typeof log === "string")
            return { at: new Date(), ns: "socket.io", body: log }
        log.at = new Date();
        if (!log.hasOwnProperty('ns'))
            log.ns = 'unknown';
        return log;
    });

However one of the goals of the future releases is to rather provide a Winston transport.

Custom errors

   var NotFoundError   = CustomError("NotFoundError")
     , NotOwnedError   = CustomError("NotOwnedError");

   Keywords.findById(label, function(doc) {
       if (!doc)
           return cb(NotFoundError("Keyword '%s' not found", label));
       return cb(null, doc);
   }

CustomError uses the technique described by disfated here: http://stackoverflow.com/questions/464359/custom-exceptions-in-javascript .

Web applications

This is an example config file, you could put in you app's etc/config.dev.json:

    { "server": {
          "http": { "port": 5000 },
          "https": { "port": 5001, "cert": "cert+key.pem" }
      },
      "router": {
          "routes": {
              "*": {
                  "pattern": "^/bootstrap$",
                  "module": "../src/bootstrap.js"
              },
              "web.site.com:5000": [
                  { "pattern": "^/$",
                    "module": "src/controllers/web_site_com/template.js" },
                  { "pattern": "^/(app.js|app.css|app.manifest)$",
                    "module": "src/controllers/web_site_com/pipeline.js" },
                  { "pattern": "^/(css/|img/|js/|favicon.ico$)",
                    "module": "src/controllers/web_site_com/static.js" },
                  {  "module": "src/controllers/web_site_com/error404.js" }
              ]
          } 
    } }

Command-line applications

    #!/usr/bin/env node
    // vim: filetype=javascript

    var CommandLineApp = require("jazzy/CommandLineApp");

    app = new CommandLineApp();
    app.addOption(
        "configFilePath", {
            abbr: "c", help: "Path to the config file", required: true,
            metavar: "CONFIG_FILE" },
        function(app, name, args, kwargs) {
            // test if path kwargs[name] exists
            // then add to app a property configContent
            // or something like that
        }
    );
    app.addCommand(
        "create", {
            help: "Creates a new client"
        }, function(app, cmd, args, kwargs) {
            console.log("create");
            console.log(arguments);
        }
    );
    app.addLastCommandOption(
        "input", { abbr: "i", metavar: "INPUT", help: "Use INPUT as input", required: true },
        function(app, name, args, kwargs) {
            console.log("input flag");
            console.log(arguments);
        }
    );
    app.addCommand(
        "update", {
            help: "Updates a client"
        }, function(app, cmd, args, kwargs) {
            console.log("update");
            console.log(arguments);
        }
    );
    app.addCommand(
        "delete", {
            help: "Deletes a client"
        }, function(app, cmd, args, kwargs) {
            console.log("delete");
            console.log(arguments);
        }
    );

    app.run();

Object validation schemas

    var Schema      = require('jazzy/schema'),
        validators  = require('jazzy/validators');

    var schema = new Schema({
        timestamp: function(v) { 
            return validators.validateDateFromString(v);
        },
        nonce: function(v) {
            return validators.validateNumberFromString(v);
        },
        digest: function(v) {
            return validators.validateHexString(v, {minLen:64,maxLen:64});
        }
    }).allowUselessFields(true);

    var onGetEnd = exports.onGetEnd = function(request, response)
    {
        schema.validate(request.kwargs, function(errors, params) {
            var responseParams = {
            };
            if (errors.length) {
                var error = errors.pop();
                responseParams.fieldProblem = error[0];
                responseParams.fieldName    = error[1];
                response.redirect(307, getUrl("http://example.com/error", responseParams));
                return;
            }
            responseParams.OK   = '1';
            response.redirect(307, getUrl("http://example.com/success", responseParams));
        });
    }

Goals

Version 1 should provide:

  1. File Winston transport which uses strftime to parse file path.
  2. Importer / Updater / Yielder / ( Fetcher Parser ) for your cold webservices needs.
  3. Scheduler.
  4. Tributes.
  5. JSON-RPC.
  6. Way to define errors and common error types.

Version 2 should provide:

  1. Secure API calls with URL.
  2. Some more object and string helpers than the ones in underscore.
  3. Daemonize.

Version 3 should provide:

  1. Helpers for web apps.
  2. Grunt support.
  3. Grok support.
