#NODEJS LOCAL DYNAMODB HOW TO#

If you want how to create your Skill with the ASK CLI, please follow the first step explained in my Node.js Skill sample. With ASK CLI, you have access to the Skill Management API, which allows you to manage Alexa skills programmatically from the command line. The Alexa Skills Kit Command Line Interface (ASK CLI) is a tool for you to manage your Alexa skills and related resources, such as AWS Lambda functions.

Java Runtime Environment (JRE) version 6.x or newer.

Here you have the technologies used in this project DynamoDB is a fully managed NoSQL database offered by Amazon Web Services. In other words, Database Mocking is a simulation of a database either with few records or with an empty database.ДЄlexa Skills can use DynamoDB to persist data between sessions.

#NODEJS LOCAL DYNAMODB CODE#

This technique is also useful when you are writing your code on your local laptop. Using this technique, you can focus on getting the test data-sets ready once, and then use it on different test phases regarding the environments by using mocking.

Mocking database is a technique that allows you to set the desired database state in your tests to let specific data-sets ready for future test execution. In this article we will discuss how to mocking a DynamoDB.

Alteration of data is quicker as compared to the web-based setup due to the absence of network overhead.Mocking away dependencies - especially external dependencies - is common practice when writing tests or when you are developing locally.Дependency injection typically makes it easy to provide a mock implementation for your dependencies, e.g.

The process of deletion is instantaneous in the local setup.

Generally, the local installation ignores throughput.

Tables are created instantaneously in local setup but the services provided by AWS consume more time.

The key difference between the local setup and web-based setup of DynamoDB are listed below:

Other changes are based on a requirement-centric analysis of your application.Дifference between local and web-based setup: The primary change consists of altering the endpoint from a local point to an AWS region. The changes depend on code language and a few other factors. A JavaScript shell can also be used as a GUI console for DynamoDB.ДЄt the deployment stage, you will need to make changes to your code. Programming languages like Ruby, Java, Python, C#, Erlang, PHP, and Perl are supported by DynamoDB. aws dynamodb list-tables -endpoint-url Now your local installation is all set and you can start building your application. For example, use the following command to list DynamoDB tables. To access DynamoDB running locally with the AWS CLI(Command Line Interface), use the вЂ“endpoint-url parameter.

After this to access DynamoDB either through AWS CLI or command prompt, we need to configure our credentials as shown below: AWS Access Key ID: 'YourKeyId'ДЄWS Secret Access Key: 'YourSecretAccessKey'.

Now using the command prompt navigate to the location where you moved the extracted data and run the below command: java =./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb.

Extract the downloaded file and move it to the location where you want to install the console.
