What you'll learn:
- Build a NodeJS/HapiJS API server.
- Integrate Python NLP sentiment analysis in their NodeJS application.
- Build a ReactJS application that interacts with a server API.
- Understand Promises in JavaScript.
- Understand fetch API in JavaScript.
- Integrate python in NodeJS.
With this course, youwill learn tobuildaNodeJS (HapiJS) JSON-based Restful API backend for sentiment analysis and a ReactJS client that interacts with the API. HapiJS, a rich and configuration-centric serverframework for NodeJSallows us to build powerful and configurable applications. Moreover, sentiment analysis allows automated reasoning about sentences to determinewhether they are positive, negative or neutral. A popular use case is to find out how people feel about a product or service. This is course introduces you to a powerful Python package, NLTK(Natural Language ToolKit), that allows you to do more than sentiment analysis. Aside from learning and building together a HapiJSAPI and ReactJS App, we learn how to integrate the NLTK Python package (and for that matter any other Python package) into a NodeJSapplication.
We will start by first building a HapiJS server that can receive textsand send simple responses. We will interact with our server via Chrome's Postman plugin. Then, we will integrate VADERNLTKsentiment analysis into the server, that will allow the server to determine the sentiments of sentences in English. Afterwards, we will build a ReactJS client that allows us to enter and send sentences to the server and display the sentiment of a our sentence.
So, in summary, thislearning by doing doing course isprepared for you to:
- learn theHapiJS framework of NodeJS for building APIbackends.
- learn to use the VADER module of theNLTK (Natural Language ToolKit) for sentiment analysis.
- learn to integrate Python modulesinto NodeJS.
- learn to build apps in ReactJS.
- understand the new concepts in JavaScript (e.g Promise, arrow functions, etc).
