\"\"Hapi.js (also known as hapi) is an open-source framework for web applications. The most common use of<\/a> hapi is to build web services such as JSON API. You can build application programming interface (API) servers, websites, and HTTP proxy applications with hapi.js.<\/p>\n

Hapi simplified the way in which developers write highly scalable APIs<\/a>. It is powerful and feature-rich framework with solid architecture. If you are new to hapi.js, I suggest you read my previous introduction<\/a> article.<\/p>\n

What Is a REST API?<\/h2>\n

A REST(Representational State Transfer) is an application program interface(API<\/a>) that uses HTTP<\/a> requests to GET, PUT, POST and DELETE data.<\/p>\n

A RESTful API\u2014also referred to as a RESTful web service\u2014is based on representational state transfer (REST<\/a>) technology, an architectural style and approach to communications often used in web services<\/a> development.<\/p>\n

Hapi provides some powerful features for building REST API. Some examples are Routing, Plugins, Logging, HTTP interface, Error Handling, etc.<\/p>\n

You do not need to work with the raw Node.js HTTP library. Hapi encapsulates the request and response object of HTTP request. Hapi allows you to build REST API faster. Let me show you how you can create APIS in hapi.js and mongoose<\/p>\n

Installing Hapi.js<\/h2>\n

First of all, I am going to show you how to install hapi.js. Open your terminal and run the below commands. Npm init<\/strong> will create a new package.json<\/strong> file in the root directory of your application. You can install hapi on your local machine by using the npm install command. Npm(Node Package Manager) will grab the hapi package from the repository and save it to your local node_modules<\/strong> folder.<\/p>\n

npm init — yes
\nnpm install —\u00a0save hapi<\/em>
\n<\/span><\/p>\n

API Endpoints Overview<\/h3>\n

I will show you how to build pure CRUD<\/strong> (Create, Read, Update, Delete) API endpoints with hapi.js. I have used some HTTP verbs such as POST<\/strong>, GET<\/strong>, PUT<\/strong>, and, DELETE<\/strong>.<\/p>\n

    \n
  • POST<\/strong> \u00a0is used to create new records in the database<\/li>\n
  • GET<\/strong> request is used to fetch records from the endpoints<\/li>\n
  • PUT<\/strong> is used to update the record<\/li>\n
  • DELETE<\/strong> is used to delete the record with MongoDB<\/li>\n<\/ul>\n

    Creating a New Server<\/h3>\n

    First of all, we need to create a new local server in hapi.js. Hapi allows you to create a new instance of the server from the hapi.Server()<\/strong> method. You can configure hapi server on a local machine by providing the host and port configuration. You must start the server by using the server.start<\/strong> method. If something goes wrong while starting the server it will throw this error:<\/p>\n
