### Install meanio and mean-cli

Source: https://github.com/linnovate/meanio/wiki/Adding-A-Package

Installs the global meanio and mean-cli tools required for managing MEAN.js projects. These commands ensure you have the necessary command-line interface for MEAN.js development.

```javascript
npm install -g meanio
npm install -g mean-cli
```

--------------------------------

### Initialize a MEAN.js Application

Source: https://github.com/linnovate/meanio/wiki/Adding-A-Package

Initializes a new MEAN.js application named 'testApp' and installs its dependencies. This sets up the basic project structure for a MEAN.js application.

```javascript
mean init testApp
cd testApp
npm install
```

--------------------------------

### Install meanio Package

Source: https://github.com/linnovate/meanio/blob/master/README.md

Installs the meanio npm package using npm. This package is the core for managing mean packages and extending functionality within the MEAN.IO project.

```shell
$ npm install meanio
```

--------------------------------

### Meanio Server Instance Initialization and Serve Method

Source: https://github.com/linnovate/meanio/wiki/Abstraction-layers-and-Engines

Describes the process of obtaining a meanioinstance and inserting a 'serve' method into Meanio.prototype. This method is responsible for initiating the server operation by handling the 'database' dependency.

```javascript
Meanio.prototype.serve = function() {
  // Registers a handler for the 'database' dependency
  // Sets active flag and remembers options
  // Calls genericServe (bound to Meanio function)
};
```

--------------------------------

### Meanio Server Bootstrap Process

Source: https://github.com/linnovate/meanio/wiki/Abstraction-layers-and-Engines

Details the server bootstrap sequence initiated by the 'serveWithDB' method. It involves producing an engine instance, calling its 'beginBootstrap' and 'endBootstrap' methods, and managing the 'app' dependency resolution.

```javascript
function serveWithDB() {
  // Produce Engine instance (e.g., ExpressEngine)
  const engine = produceEngine(config.serverengine);

  // Synchronous bootstrap: create RPC library instance, initial settings
  engine.beginBootstrap();

  // Register 'app' dependency, potentially with direct Express setup
  // ... 'app' dependency resolver function ...
  // Hack: return this.app instead of this for Server Core mockup

  // Wait for 'onInstance' event handlers to resolve

  // Asynchronous bootstrap completion
  engine.endBootstrap(callback);
}
```

--------------------------------

### Require Mean.io Core

Source: https://github.com/linnovate/meanio/wiki/Modular-core

Demonstrates how to obtain the Mean.io core instance, which serves as the server instance itself. This is the primary entry point for interacting with the framework.

```javascript
require('meanio');
```

--------------------------------

### Mean.io Boot Script Initialization

Source: https://github.com/linnovate/meanio/wiki/Angular-boot-script

This script demonstrates the core logic of the mean.io boot script. It initializes the Angular application by bootstrapping with the 'mean' module and dynamically adds modules declared by packages, ensuring all dependencies are met before application startup.

```javascript
'use strict';

angular.element(document).ready(function() {
  //Fixing facebook bug with redirect
  if (window.location.hash === '#_=_') window.location.hash = '#!';

  //Then init the app
  angular.bootstrap(document, ['mean']);

});

// Dynamically add angular modules declared by packages
var packageModules = [];
for (var index in window.modules) {
  angular.module(window.modules[index].module, window.modules[index].angularDependencies || []);
  packageModules.push(window.modules[index].module);
}

// Default modules
var modules = ['ngCookies', 'ngResource', 'ui.bootstrap', 'ui.router'];
modules = modules.concat(packageModules);

// Combined modules
angular.module('mean', modules);
```

--------------------------------

### onInstance Event Handler Signature

Source: https://github.com/linnovate/meanio/wiki/Modular-core

Describes the parameters passed to `onInstance` event handlers. These handlers are crucial for server startup as the server waits for all provided defers to be resolved.

```APIDOC
onInstance Event Handler:
  Parameters:
    - meanio_instance: The Meanio instance being created.
    - q_defer: A promise defer object that the handler must eventually resolve.
  Behavior:
    - The Meanio server will not start until all `onInstance` handlers resolve their respective `q_defer` objects.
```

--------------------------------

### Handling Express Static File Serving (Hack)

Source: https://github.com/linnovate/meanio/wiki/Abstraction-layers-and-Engines

Addresses the challenge of providing a 'useStatic' method for packages to define static resource paths. Due to Express's architecture, this method is directly inserted into the Express instance, simplifying dependency management for packages.

```javascript
// Inside 'app' resolver function or similar context:
// Directly inserting useStatic into the Express instance
this.app.useStatic = function(path) {
  // Logic to add static path
};

// This hack removes scattered 'require('express')' calls from packages.
```

--------------------------------

### Express Engine and ServerEngine Abstraction

Source: https://github.com/linnovate/meanio/wiki/Abstraction-layers-and-Engines

Explains the Server Abstraction layer, specifically the 'ExpressEngine' class inheriting from 'ServerEngine'. It highlights the role of these classes in managing server operations and dependencies.

```javascript
class ServerEngine {
  // ... methods like beginBootstrap, endBootstrap ...
}

class ExpressEngine extends ServerEngine {
  // ... specific Express implementation ...
  // Manages Express app instance
  // May require prototype shaping for methods like useStatic
}
```

--------------------------------

### Create a New MEAN.js Package

Source: https://github.com/linnovate/meanio/wiki/Adding-A-Package

Generates a new package named 'testPackage' within the current MEAN.js project. meanio is responsible for lazyloading this package, which includes server/client components and routing capabilities.

```javascript
mean package testPackage
```

--------------------------------

### Dependency Declaration Style

Source: https://github.com/linnovate/meanio/wiki/Modular-core

Illustrates the preferred, more flexible method for declaring dependencies in Mean.io, allowing handlers to specify dependencies by name as strings before the function.

```javascript
'database','auth',function(database,auth){...}
```

--------------------------------

### Package Angular Module Declaration

Source: https://github.com/linnovate/meanio/wiki/Angular-boot-script

This is a common pattern for packages in mean.io to declare their own Angular module. This declaration is intended to ensure the package's module exists, potentially as a fallback if the package's code is loaded before the main boot script.

```javascript
'use strict';

angular.module('mean.package1',[]);
```
