pwix:core-app

What is it ?

A package which provides some core features to our applications.

Features

Page management

A core feature of any application is to display pages to the users, to propose menus, maybe to use modal dialogs to provide informations or let the user enter datas.

pwix:core-app try to take in charge the common code, for example the user is he allowed to access the required display unit, is he allowed to enter data in it, and so on.

Pages collection as obviously described by the application, and the current run context, are both materialized by classes that the application may (and even should) derive:

  • CoreApp.RunContext

Application administrator

An application may need a super user, a user who is allowed to modify some special configuration settings, or to do anything... The pwix:startup-app-admin package, when installed in an application, provides the code needed to define this application administrator, verify his/her email address, attribute required role.

To take advantage of this feature, the application must:

  • install the required package:
    meteor add pwix:startup-app-admin
  • configure this package to take advantage of it:
1    CoreApp.configure({
2        withStartupAppAdmin: true
3    });

When these two conditions are met, a reactive data source is

Environment management

While nodejs defines only three environments (development, staging and production), and though Meteor has followed the same route, we strongly believe that many more would be better, and that we should not be tied to such only three parts.

We so use the APP_ENV environment variable to address our own environment identifier. Through this identifier, we ask the server to publish the setings recorded inside of its private settings (see pwix:env-settings).

The settings are read from the server settings for this environment through the path Meteor.settings[APP.name].environments[<environment_identifier>].

If not specified in the APP_ENV variable, the environment identifier falls back to the nodejs environment name.

Settings management

pwix:core-app the settings dedicated to the current environment as the CoreApp.envSettings reactive var.

Provides

CoreApp

The exported CoreApp global object provides following items:

CoreApp.envSettings

A ReactiveVar which is set at startup with the settings for this environment. It contains following keys:

  • env: the name of the running environment from APP_ENV environment variable
  • settings: the relevant settings read from the APP/private/config/server JSON configuration.

Configuration

The package's behavior can be configured through a call to the CoreApp.configure() method, with just a single javascript object argument, which itself should only contains the options you want override.

Known configuration options are:

  • adminRole

    Define the name of the application administrator role.

    Default to 'APP_ADMINISTRATOR'.

    As a reminder, this same value is expected to be also configured in the pwix:startup-app-admin package.

  • layout

    Define the name of the default layout for a page which doesn't define it.

    Default to 'app'.

    This layout is expected to be provided by the application.

  • routePrefix

    Define the prefix of the routes to be used in provided links.

    Default to /coreUI.

  • verbosity

    Define the expected verbosity level.

    The accepted value can be any or-ed combination of following:

    • CoreApp.C.Verbose.NONE

      Do not display any trace log to the console

    • CoreApp.C.Verbose.CONFIGURE

      Trace CoreApp.configure() calls and their result

    • CoreApp.C.Verbose.PAGE

      Trace changes on page and relevant authorizations

Please note that CoreApp.configure() method should be called in the same terms both in client and server sides.

Remind too that Meteor packages are instanciated at application level. They are so only configurable once, or, in other words, only one instance has to be or can be configured. Addtionnal calls to CoreApp.configure() will just override the previous one. You have been warned: only the application should configure a package.

NPM peer dependencies

Starting with v 0.1.0, and in accordance with advices from the Meteor Guide, we no more hardcode NPM dependencies in the Npm.depends clause of the package.js.

Instead we check npm versions of installed packages at runtime, on server startup, in development environment.

Dependencies as of v 1.0.0:

1    'ellipsize': '^0.5.1',
2    'lodash': '^4.17.0',
3    'strftime': '^0.10.2',
4    '@vestergaard-company/js-mixin': '^1.0.3'

Each of these dependencies should be installed at application level:

    meteor npm install <package> --save

Translations

New and updated translations are willingly accepted, and more than welcome. Just be kind enough to submit a PR on the Github repository.

Cookies and comparable technologies

None at the moment.
