The best time is before starting, using our goals as beacons for our choices. As such, it can be difficult to get started with building full web applications with Node. How to create mvc db Build Plugins with Hapi. As with a lot of other cool things in computer history, the MVC model was conceived at PARC for the Smalltalk language as a solution to the problem of organizing applications with graphical user interfaces.
It was created for desktop applications, but since then, the idea has been adapted to other mediums including the web.
We can describe the MVC architecture in simple words: The part of our application that will deal with the database or any data-related functionality. Everything the user will see. The logic of our site, and the glue between models and views. Here we call our models to get the data, then we put that data on our views to be sent to the users.
Our application will allow us to publish, see, edit and delete plain-text notes. You can check out the final application in the accompanying GitHub repositoryso you get a general overview of the application structure.
Laying out the Foundation The first step when building any Node. Instead of creating this file manually, npm can do the job for us using the init command: It provides a good balance between simplicity, stability and feature availability that will work well for our use case although there are other options that would also work just fine.
It will also download the Hoek utility library that will help us write shorter error handlers, among other things. Now we can create our entry file — the web server that will start everything. Go ahead and create a server. Next, we include our dependencies and instantiate a new server object where we set the connection port to the port can be any number above and below The handler function can take two arguments: The first one contains information about the HTTP call, and the second will provide us with methods to handle our response to that call.
Finally, we start our server with the server. As you can see, we can use Hoek to improve our error handling, making it shorter. This is completely optional, so feel free to omit it in your code, just be sure to handle any errors.
Storing Our Settings It is good practice to store our configuration variables in a dedicated file. This file exports a JSON object containing our data, where each key is assigned from an environment variable — but without forgetting a fallback value.
In this file, we can also have different settings depending on our environment e. For example, we can have an in-memory instance of SQLite for development purposes, but a real SQLite database file on production.
Selecting the settings depending on the current environment is quite simple. Since we also have an env variable in our file which will contain either development or production, we can do something like the following to get the database settings for example: Also, we can add support for a.
You can find an example in the dotenv repository. If you decide to also use a. Omit this line if you don't want to use this functionality require 'dotenv'. This project was tested on Node v6.
If you get any errors, ensure you have an updated installation. Defining the Routes The definition of routes gives us an overview of the functionality supported by our application.
To create our additional routes, we just have to replicate the structure of the route that we already have in our server. To define the first route, add the following object to the array: The description field in the config section is only for documentation purposes.
Add the following definitions next to the previous route: The only exception is the delete route.I am writing a web application that will allow a user to browse to multiple web pages within the website making certain requests. All information that the user inputs will be stored in an object that I created.
