New global aliases

Events:

• ON(name, fn) alias for F.on()
• OFF(name, [fn]) alias for F.removeListener(name, fn) or F.removeAllListeners(name)
• EMIT(name, arg1, arg..N) alias for F.emit()

ON('ready', function() {
   console.log('Framework is loaded.');
});

Schemas:

• $GET(schema, [options], callback) alias for GETSCHEMA(name).get()
• $QUERY(schema, [options], callback) alias for GETSCHEMA(name).query()
• $WORKFLOW(schema, name, [options], callback) alias for GETSCHEMA(name).workflow2()
• $TRANSFORM(schema, name, [options], callback) alias for GETSCHEMA(name).transform2()
• $OPERTION(schema, name, [options], callback) alias for GETSCHEMA(name).transform2()
• $MAKE(schema, model, [filter], [callback], [novalidate], [argument]) alias for GETSCHEMA(name).make()

$QUERY('User', { page: 1 }, function(err, response) {
   console.log(err, response);
});

Other:

• WAIT alias for U.wait()

A new alternative of schema declaration

An small example:

NEWSCHEMA('User').make(function(schema) {

    schema.setSave(function($) {
        // $.error
        // $.model
        // $.options
        // $.callback
        // $.controller
    });

    schema.addWorkflow('name', function($) {
        // $.error
        // $.model
        // $.options
        // $.callback
        // $.controller
    });

});

Debugging of Total.js application

I have added a debug logging into the framework. You can enable it via allow-debug : true in a config file or by passing options to http method:

require('total.js').http('release', { debug: true });

Example of output:

2017-04-08 23:06:19 ---------> init
2017-04-08 23:06:19 ---------> HTTP listening
2017-04-08 23:06:19 ---------> clear temporary
2017-04-08 23:06:19 ---------> clear temporary (done)

• the framework creates /usage.log file when it is initialized
• at every service interval the file /usage.log is updated
• created for critical situations

Scheduler

Now scheduler can be cleared via F.clearSchedule().

var schedule = F.schedule('12:00', '1 day', NOOP);

// Remove scheduler
F.clearSchedule(schedule);

Components

The components mechanism supports groups to render all components from the group:

// A component declaration
// New field "group":
exports.group = 'name';

<div>
    @{components('groupname', { custom: 'Settings (optional)' });
</div>

This mechanism can extend your web applications (e.g. Total.js Messenger uses this mechanism).

Consolidated config names

IMPORTANT: don't worry all older names will be work the next 3 versions, so you have time for replacing older values. I have updated more than 60 projects because of that.

mail.smtp           : old name
mail-smtp           : new name

mail.smtp.options   : old name
mail-smtp-options   : new name

mail.address.from   : old name
mail-address-from   : new name

mail.address.reply  : old name
mail-address-reply  : new name

mail.address.copy   : old name
mail-address-copy   : new name

Easy way to change SMTP server

I have added a new method for easy changing of SMTP server with a check via Mail.try(). More information in documentation.

F.useSMTP('hostname', { user: '', password: '' });

Deferred functions

• an experimental feature
• documentation

[ Not-cached .................... slowest (214 ms)
[ Cached ....................... +72.0% fastest (60 ms)

// A helper function
function something_async(controller, callback) {
    callback(controller);
}

// Worse performance
function some_controller_action_nocached() {
    var controller = this;
    something_async(controller, function(controller) {
        controller.plain('OK');
    });
}

// +70% better performance
function some_controller_action_cached() {
    var controller = this;
    something_async(controller, cached);
}

function cached(controller) {
    controller.plain('OK');
}

How it works?

Framework automatically parses all functions function DEFER and saves them to the helper variable.

// RAW CODE
function some_controller_action() {
    var controller = this;
    something_async(controller, function DEFER(controller) {
        controller.plain('OK');
    });
}

// RESULT
function some_controller_action() {
    var controller = this;
    something_async(controller, F.temporary.defer.D1936555);
}
