Scope app middleware to a list of paths
Add a new argument to `app.middleware` allowing developers
to restrict the middleware to a list of paths or regular expresions.
Modify `app.middlewareFromConfig` to pass `config.paths` as the second
arg of `app.middleware`.
Examples:
// A string path (interpreted via path-to-regexp)
app.middleware('auth', '/admin', ldapAuth);
// A regular expression
app.middleware('initial', /^\/~(admin|root)/, rejectWith404);
// A list of scopes
app.middleware('routes', ['/api', /^\/assets/.*\.json$/], foo);
// From config
app.middlewareFromConfig(
handlerFactory,
{
phase: 'initial',
paths: ['/scope', /^\/(a|b)/]
});

Middleware phases - initial implementation
Modify the app and router implementation, so that the middleware is
executed in order defined by phases.
Predefined phases:
'initial', 'session', 'auth', 'parse', 'routes', 'files', 'final'
Methods defined via `app.use`, `app.route` and friends are executed
as the first thing in 'routes' phase.
API usage:
app.middleware('initial', compression());
app.middleware('initial:before', serveFavicon());
app.middleware('files:after', loopback.urlNotFound());
app.middleware('final:after', errorHandler());
Middleware flavours:
// regular handler
function handler(req, res, next) {
// do stuff
next();
}
// error handler
function errorHandler(err, req, res, next) {
// handle error and/or call next
next(err);

Middleware phases - initial implementation
Modify the app and router implementation, so that the middleware is
executed in order defined by phases.
Predefined phases:
'initial', 'session', 'auth', 'parse', 'routes', 'files', 'final'
Methods defined via `app.use`, `app.route` and friends are executed
as the first thing in 'routes' phase.
API usage:
app.middleware('initial', compression());
app.middleware('initial:before', serveFavicon());
app.middleware('files:after', loopback.urlNotFound());
app.middleware('final:after', errorHandler());
Middleware flavours:
// regular handler
function handler(req, res, next) {
// do stuff
next();
}
// error handler
function errorHandler(err, req, res, next) {
// handle error and/or call next
next(err);

Middleware phases - initial implementation
Modify the app and router implementation, so that the middleware is
executed in order defined by phases.
Predefined phases:
'initial', 'session', 'auth', 'parse', 'routes', 'files', 'final'
Methods defined via `app.use`, `app.route` and friends are executed
as the first thing in 'routes' phase.
API usage:
app.middleware('initial', compression());
app.middleware('initial:before', serveFavicon());
app.middleware('files:after', loopback.urlNotFound());
app.middleware('final:after', errorHandler());
Middleware flavours:
// regular handler
function handler(req, res, next) {
// do stuff
next();
}
// error handler
function errorHandler(err, req, res, next) {

Scope app middleware to a list of paths

Examples:

app.middleware('initial', /^\/~(admin|root)/, rejectWith404);
// A list of scopes

Scope app middleware to a list of paths
Add a new argument to `app.middleware` allowing developers
to restrict the middleware to a list of paths or regular expresions.
Modify `app.middlewareFromConfig` to pass `config.paths` as the second
arg of `app.middleware`.
Examples:
// A string path (interpreted via path-to-regexp)
app.middleware('auth', '/admin', ldapAuth);
// A regular expression
app.middleware('initial', /^\/~(admin|root)/, rejectWith404);
// A list of scopes
app.middleware('routes', ['/api', /^\/assets/.*\.json$/], foo);
// From config
app.middlewareFromConfig(
handlerFactory,
{
phase: 'initial',
paths: ['/scope', /^\/(a|b)/]
});

Middleware phases - initial implementation
Modify the app and router implementation, so that the middleware is
executed in order defined by phases.
Predefined phases:
'initial', 'session', 'auth', 'parse', 'routes', 'files', 'final'
Methods defined via `app.use`, `app.route` and friends are executed
as the first thing in 'routes' phase.
API usage:
app.middleware('initial', compression());
app.middleware('initial:before', serveFavicon());
app.middleware('files:after', loopback.urlNotFound());
app.middleware('final:after', errorHandler());
Middleware flavours:
// regular handler
function handler(req, res, next) {
// do stuff
next();
}
// error handler
function errorHandler(err, req, res, next) {
// handle error and/or call next
next(err);
}

Simplify `app.defineMiddlewarePhases`
Refactor the implementation to use the new method `phaseList.zipMerge`.
This is commit is changing the behaviour in the case when
the first new phase does not exist in the current list.
Before the change, all new phases were added just before the "routes"
phase.
After this change, new phases are added to the head of the list,
until an existing phase is encountered, at which point the regular
merge algorithm kicks in.
Example:
app.defineMiddlewarePhases(['first', 'routes', 'subapps']);
Before the change: code throws an error - 'routes' already exists.
After the change: phases are merged with the following result:
'first', 'initial', ..., 'routes', 'subapps', ...

Add createModelFromConfig and configureModel()
Add new API allowing developers to split the model definition and
configuration into two steps:
1. Build models from JSON config, export them for re-use:
```js
var Customer = loopback.createModelFromConfig({
name: 'Customer',
base: 'User',
properties: {
address: 'string'
}
});
```
2. Attach existing models to a dataSource and a loopback app,
modify certain model aspects like relations:
```js
loopback.configureModel(Customer, {
dataSource: db,
relations: { /* ... */ }
});
```
Rework `app.model` to use `loopback.configureModel` under the hood.
Here is the new usage:
```js
var Customer = require('./models').Customer;
app.model(Customer, {
dataSource: 'db',
relations: { /* ... */ }
});
```
In order to preserve backwards compatibility with loopback 1.x,
`app.model(name, config)` calls both `createModelFromConfig`
and `configureModel`.

Scope app middleware to a list of paths
Add a new argument to `app.middleware` allowing developers
to restrict the middleware to a list of paths or regular expresions.
Modify `app.middlewareFromConfig` to pass `config.paths` as the second
arg of `app.middleware`.
Examples:
// A string path (interpreted via path-to-regexp)
app.middleware('auth', '/admin', ldapAuth);
// A regular expression
app.middleware('initial', /^\/~(admin|root)/, rejectWith404);
// A list of scopes
