### `bloggify.json` vs `bloggify.js`

In the root of the project you can create a file called `bloggify.js` or `bloggify.json` (whatever seems more convenient for your case).

**`bloggify.json`**

For simple applicatoins where dynamic parameters are not needed, you can simply  use a JSON file. It should be an object:

```js
{
    /* your options here, as JSON */
}
```

**`bloggify.js`**

When you want to have dynamic configuration properties, `bloggify.js` becomes handy.

```js
module.exports = {
    /* your options */
}
```

### Configuration fields and defaults

Below are the fields you can configure in the `bloggify.js` (or `bloggify.json`) file:

  - `title` (String): The application name. For convenience (in case it's
     not set), the default is an empty string (`""`).

  - `description` (String): The application description. For convenience
     (in case it's not set), the default is an empty string (`""`).

 - `plugins` (Array): The plugins to load. A specific element should be
    either a string or an array of two values (the value name and the
    configuration object).

    Example:

    ```js
    [
       // Load the web sockets module
       "ws"
     , ["some-interesting-module",{
         "and": "some",
         "interesting": "configuration"
       }]
    ]
    ```

    **Note**: If the module name starts with `bloggify-`, you can omit
    that part of the name.
    Example: To load `bloggify-ws`, you can simply use `ws`.

  - `core_plugins` (Array): Like `plugins`, but these have greater
     priority when starting the app.

     There are some additional core plugins which are loaded automatically.

     The specific order of loading core plugins is:

      0. Models (sequelize/mongoose)
      1. Custom plugins configured in `bloggify.js(on)`
      2. Actions
      3. Router
      4. Renderer(s)

  - `db_uri` (String): The database URI. It can be set in the options,
     or via an environment variable: `DB_URI`. The recommended way is
     to use the environment variable set in the `.env` file or in the
     deployment platform settings (e.g. Heroku).

     The uri is parsed and the specific dialect is handled. Currently,
     these dialects are supported:

     **`mongodb`**

     URI: `mongodb://localhost/your-database-name`
     Needed peer dependencies: `connect-mongo`, `bloggify-mongoose`

     You need to install these in your app folder:

     ```sh
     npm install connect-mongo bloggify-mongoose
     ```

     If no models are used, you don't need to install
     `bloggify-mongoose`. `connect-mongo` will be used for
     session management.

     The models will be created in the models folder (default: `app/models`).

     Example:

     **`Topic.js`**
     ```
     const TopicSchema = new Bloggify.db.Schema({
         title: {
             type: String,
             text: true
         },
         body: {
             type: String,
             text: true
         },
     })
     module.exports = Bloggify.db.model("Topic", TopicSchema)
     ```

     **`mysql`**

     URI: `DB_URI=mysql://root:password@host:port/your-database-name`
     Needed peer dependencies: `express-mysql-session`, `bloggify-sequelize`

     You need to install these in your app folder:

     ```sh
     npm install express-mysql-session bloggify-sequelize
     ```

     If no models are used, you don't need to install
     `bloggify-mongoose`. `connect-mongo` will be used for
     session management.

     The models will be created in the models folder (default: `app/models`).

     Example:

     **`User.js`**

     ```js
     const Sequelize = Bloggify.sequelize

     const Subject = Sequelize.db.define("subject", {
         name: {
             type: Sequelize.STRING
         }
     }, {
         charset: "utf8mb4"
     })

     module.exports = Subject
     ```

  -  `db_options` (Object): Additional options to be passed to the
     database plugin (`bloggify-sequelize` or `bloggify-mongoose`).
  - `server` (Object) Server ([`lien`](https://github.com/lienjs/lien)) related settings.
    - `port` (Boolean): The server's port (default: `process.env.PORT || 8080`).
    - `host` (Boolean): The server's host (default: `null`).
    - `csrf` (Boolean): Wether to enable csrf validation or not (default: `true`).
    - `session` (Object|Boolean): The session settings, or `false` to
       disable the session management. In most of the cases you will
       not need to change this.
  - `paths` (Object): The paths options. Do *not* change these unless you have a good reason.
    - `bloggify` (String): The Bloggify directory (by default the root of the app).
    - `public_main` (String): The public directory endpoint (default: `"/@/bloggify/public/"`)
    - `public_assets` (String): The public core endpoint (default: `"/@/bloggify/assets/"`)
    - `css_assets` (String): The CSS assets endpoint (default: `"/@/bloggify/css-assets/"`)
    - `errors` (String): The errors directory (default: `"/app/errors"`)
        In this folder you can configure custom errors. For instance, you can create `FORBIDDEN.json`:

        ```js
        {
            "message": "Forbidden.",
            "status": 403
        }
        ```

        Then, in the code, when you `throw Bloggify.errors.FORBIDDEN()`, this error will be thrown.

        You can pass additional arguments, such as:

        ```js
        {
            "message": "{1} does not have access to this resource.",
            "status": 403
        }
        ```

        Then you can do:

        ```js
        throw Bloggify.errors.FORBIDDEN("Beky")
        // => Beky does not have access to this resource.
        ```

    - `models` (String): The models directory (default: `"/app/models"`). Keep
       here the application models. See above (the `db_uri` section) how the files should look like.
    - `routes` (String): The routes directory (default: `"/app/routes"`).
    - `services` (String): The services (default: `"/app/services"`) directory.
