Directory structure
-------------------

On initialization directories tree generated, like that:

`
.
|-- app
| |-- assets
| | |-- coffeescripts
| | | -- application.coffee
| | -- stylesheets
| | -- application.styl
| |-- controllers
| | |-- admin
| | | |-- categories_controller.js
| | | |-- posts_controller.js
| | | -- tags_controller.js
| | |-- comments_controller.js
| | -- posts_controller.js
| |-- models
| | |-- category.js
| | |-- post.js
| | -- tag.js
| |-- tools
| | -- database.js
| |-- views
| | |-- admin
| | | -- posts
| | | |-- edit.ejs
| | | |-- index.ejs
| | | |-- new.ejs

| | |-- posts_helper.js
| | -- tags_helper.js
| -- posts_helper.js
-- config
|-- database.json
|-- routes.js
|-- tls.cert
-- tls.key
`

HTTPS Support
-------------

Just place your key and cert into config directory, compound will use it.
Default names for keys are tls.key and tls.cert, but you can store in in another place, in that case just pass filenames to createServer function:
server.js

`js
require('compound').createServer({
key: fs.readFileSync('/tmp/tls.key').toString(),
cert: fs.readFileSync('/tmp/tls.cert').toString()
});
`

Few helpful commands:

`sh


generate private key

openssl genrsa -out /tmp/tls.key

generate cert

openssl req -new -x509 -key /tmp/tls.key -out /tmp/tls.cert -days 1095 -batch
`

Routing
-------

Now we do not have to tediously describe REST routes for each resource, enough to write in config/routes.js code like this:

`js
exports.routes = function (map) {
map.resources('posts', function (post) {
post.resources('comments');
});
};
`

instead of:

`js
var ctl = require('./lib/posts_controller.js');
app.get('/posts/new.:format?', ctl.new);
app.get('/posts.:format?', ctl.index);
app.post('/posts.:format?', ctl.create);
app.get('/posts/:id.:format?', ctl.show);
app.put('/posts/:id.:format?', ctl.update);
app.delete('/posts/:id.:format?', ctl.destroy);
app.get('/posts/:id/edit.:format?', ctl.edit);

var com_ctl = require('./lib/comments_controller.js');
app.get('/posts/:post_id/comments/new.:format?', com_ctl.new);
app.get('/posts/:post_id/comments.:format?', com_ctl.index);
app.post('/posts/:post_id/comments.:format?', com_ctl.create);
app.get('/posts/:post_id/comments/:id.:format?', com_ctl.show);
app.put('/posts/:post_id/comments/:id.:format?', com_ctl.update);
app.delete('/posts/:post_id/comments/:id.:format?', com_ctl.destroy);
app.get('/posts/:post_id/comments/:id/edit.:format?', com_ctl.edit);
`

and you can more finely tune the resources to specify certain actions, middleware, and other. Here are example routes for [my blog][1]:

`js
exports.routes = function (map) {
map.get('/', 'posts#index');
map.get(':id', 'posts#show');
map.get('sitemap.txt', 'posts#map');

map.namespace('admin', function (admin) {
admin.resources('posts', {middleware: basic_auth, except: ['show']}, function (post) {
post.resources('comments');
post.get('likes', 'posts#likes')
});
});
};
`

since version 0.2.0, it is possible to use generic routes:

`js
exports.routes = function (map) {
map.get(':controller/:action/:id');
map.all(':controller/:action');
};
`

if you have custom_controller with test action inside it you can now do:

`
GET /custom/test
POST /custom/test
GET /custom/test/1 // also sets params.id to 1
`

for debugging routes described in config/routes.js you can use compound routes command:

`
$ compound routes
GET / posts#index
GET /:id posts#show
sitemap.txt GET /sitemap.txt posts#map
adminPosts GET /admin/posts.:format? admin/posts#index
adminPosts POST /admin/posts.:format? admin/posts#create
newAdminPost GET /admin/posts/new.:format? admin/posts#new
editAdminPost GET /admin/posts/:id/edit.:format? admin/posts#edit
adminPost DELETE /admin/posts/:id.:format? admin/posts#destroy
adminPost PUT /admin/posts/:id.:format? admin/posts#update
likesAdminPost PUT /admin/posts/:id/likes.:format? admin/posts#likes
`

Filter by method:

`
$ compound routes GET
GET / posts#index
GET /:id posts#show
sitemap.txt GET /sitemap.txt posts#map
adminPosts GET /admin/posts.:format? admin/posts#index
newAdminPost GET /admin/posts/new.:format? admin/posts#new
editAdminPost GET /admin/posts/:id/edit.:format? admin/posts#edit
`

Filter by helper name:

`
$ compound routes Admin
newAdminPost GET /admin/posts/new.:format? admin/posts#new
editAdminPost GET /admin/posts/:id/edit.:format? admin/posts#edit
likesAdminPost PUT /admin/posts/:id/likes.:format? admin/posts#likes
`


Helpers
-------

In addition to regular helpers linkTo, formFor, javascriptIncludeTag, formFor, etc. there are also helpers for routing: each route generates a helper method that can be invoked in a view:

`html
<%- link_to("New post", newAdminPost) %>
<%- link_to("New post", editAdminPost(post)) %>
`

generates output:

`html
New post
New post
`

Controllers
-----------

The controller is a module containing the declaration of actions such as this:

`js
beforeFilter(loadPost, {only: ['edit', 'update', 'destroy']});

action('index', function () {
Post.allInstances({order: 'created_at'}, function (collection) {
render({ posts: collection });
});
});

action('create', function () {
Post.create(req.body, function () {
redirect(pathTo.adminPosts);
});
});

action('new', function () {
render({ post: new Post });
});

action('edit', function () {
render({ post: request.post });
});

action('update', function () {
request.post.save(req.locale, req.body, function () {
redirect(pathTo.adminPosts);
});
});

function loadPost () {
Post.find(req.params.id, function () {
request.post = this;
next();
});
}
`

Generators ##

Compound offers several built-in generators: for a model, controller and for
initialization. Can be invoked as follows:

`js
compound generate [what] [params]
`

what can be model, controller or scaffold. Example of controller generation:

`
$ compound generate controller admin/posts index new edit update
exists app/
exists app/controllers/
create app/controllers/admin/
create app/controllers/admin/posts_controller.js
create app/helpers/
create app/helpers/admin/
create app/helpers/admin/posts_helper.js
exists app/views/
create app/views/admin/
create app/views/admin/posts/
create app/views/admin/posts/index.ejs
create app/views/admin/posts/new.ejs
create app/views/admin/posts/edit.ejs
create app/views/admin/posts/update.ejs
`

Currently it generates only *.ejs views

Models
------

Checkout [JugglingDB][2] docs to see how to work with models.

CompoundJS Event model
----------------------

Compound application loading process supports following events to be attached
(in chronological order):

1. configure
2. after configure
3. routes
4. extensions
5. after extensions
6. structure
7. models
8. initializers

REPL console
------------

To run REPL console use command

`sh
compound console
`

or its shortcut

`sh
compound c
`

It's just simple node-js console with some Compound bindings, e.g. models. Just one note
about working with console: Node.js is asynchronous by its nature, and it's great
but it made console debugging much more complicated, because you should use callbacks
to fetch results from the database, for example. I have added one useful method to
simplify async debugging using compound console. It's named c. You can pass it
as a parameter to any function requiring callbacks, and it will store parameters passed
to the callback as variables _0, _1, ..., _N where N is index in arguments.

Example:

`
$ compound c
compound> User.find(53, c)
Callback called with 2 arguments:
_0 = null
_1 = [object Object]
compound> _1
{ email: [Getter/Setter],
password: [Getter/Setter],
activationCode: [Getter/Setter],
activated: [Getter/Setter],
forcePassChange: [Getter/Setter],
isAdmin: [Getter/Setter],
id: [Getter/Setter] }
`

Localization
------------

To add another language to app just create a .yml file in config/locales,
for example config/locales/jp.yml, copy contents of config/locales/en.yml to new
file and rename root node (en to jp in that case), also in lang section rename
name to Japanese (for example).

Next step - rename email files in app/views/emails, copy all files *.en.html
and .en.text to .jp.html and *.jp.text and translate new files.

NOTE: translation can contain % symbol(s), that means variable substitution

If you don't need locales support you can turn it off in config/environment:

`js
app.set('i18n', 'off');
`

Logger
-----

`js
app.set('quiet', true); // force logger to log into log/#{app.settings.env}.log
compound.logger.write(msg); // to log message
`

setup custom log dir:

`javascript
app.get('log dir', '/var/log/compound-app/');
`

Configuring
===========

Compound has some configuration options allows to customize app behavior

eval cache
----------

Enable controller caching, should be turned on in prod. In development mode,
disabling the cache allows the avoidance of server restarts after each model/controller change.

`js
app.disable('eval cache'); // in config/environments/development.js
app.enable('eval cache'); // in config/environments/production.js
`

model cache
-----------

Same option for models. When disabled, model files evaluated per each request.

`js
app.disable('model cache'); // in config/environments/development.js
`

view cache
----------

Express.js option, enables view caching.

`js
app.disable('view cache'); // in config/environments/development.js
`

quiet
-----

Write logs to log/NODE_ENV.log

`js
app.set('quiet', true); // in config/environments/test.js
`

merge javascripts
-----------------

Join all javascript files listed in javascript_include_tag into one

`js
app.enable('merge javascripts'); // in config/environments/production.js
`

merge stylesheets
-----------------

Join all stylesheet files listed in stylesheets_include_tag into one

`js
app.enable('merge stylesheets'); // in config/environments/production.js
`

Custom tools

Put your function to ./app/tools/toolname.js to be able to run it within application
environment as compound toolname command via CLI. See example tool in generated
example: ./app/tools/dabatase.js

Optionally you can specify some usage information on your function to be able to see
it in list of available commands (using compound command).

`javascript
module.exports.help = {
shortcut: 'db',
usage: 'db [migrate|update]',
description: 'Migrate or update database(s)'
};
``
