“Alexa, I want to make a reservation!”

How many of you are planning to make your hands dirty on the Alexa world? Curious to know how a voice bot can be build using Amazon Alexa and Node.js application? This blog is the right place for you. Let’s start.

Part 1:

First you need to identify the use case. Here we are dealing with a voice based restaurant reservation system. When a person says to Alexa that he wants to make a restaurant reservation, basically he is showing the intent to make a reservation. Also the reservation will have few slots like date of reservation, time, city etc. These are called slots. Once you identify the intents and slots for your use case, design the voice bot in Amazon Alexa Skill Kit (ASK) first. In ASK you need to define the intents, utterances, slots.

Build Docker Container for Node.js and MySQL Based Application

Blog, Web Development General /

Docker has given a different perception to application development and their run time environment. Containerization of application is very much essential now a days. Think about you have two different application in production server at same time and those applications are developed in Node.js 8 and Node.js 10 respectively. Now you can imagine how much trouble it could be to manage two different Node.js version.

If you were using Docker, you could simply spin up another container, set the Node.js version to 8.x and put it right next to your other container that has Node.js version 10.x on it, running on the same server with no problems whatsoever. That flexibility, portability and the option to more efficiently use your server resources are what make Docker so compelling to use.

Docker has given a different perception to application development and their run time environment. Containerization of application is very much essential now a days. Think about you have two different application in production server at same time and those applications are developed in PHP 7.2 and PHP 5.6 respectively. Now you can imagine how much trouble it could be to manage two different PHP version.

If you were using Docker, you could simply spin up another container, set the PHP version to 5.6 and put it right next to your other container that has PHP version 7.2 on it, running on the same server with no problems whatsoever. That flexibility, portability and the option to more efficiently use your server resources are what make Docker so compelling to use.

The below YouTube Video will tell you how to install Docker. Here we are using Ubuntu as OS but if you are an Windows user, you can create a virtual machine using Virtual Box and Install Ubuntu as Virtual OS. This approach is better as your primary or host OS is untouched from any activity required for your learning purpose. You may watch this YouTube video on How to Install Ubuntu as virtual machine (VM).
