Let's learn how to create REST API in node.js using API Gateway. We will look at connecting API Gateway with a Lambda function.

Let's look at creating an API using Lambda. Though there is a better alternative to this, which is API Gateway, for this article, let's focus on creating REST API in Node.js using AWS Lambda.

In this article, we will learn about how to use transactions in DynamoDB. NoSQL refers to a non-SQL or a non-relational database that provides a mechanism for the storage and retrieval of data modeled in other than tabular relations(unlike relational databases).

The Laravel Excel package simplifies exports and imports by wrapping PhpSpreadsheet with a manageable and elegant solution.  The PhpSpreadsheet library is written in pure PHP and includes classes for reading and writing spreadsheets such as Excel and LibreOffice Calc.

Let's look into using PostgreSQL with Node.js, performing connection to the database, and performing INSERT, READ, UPDATE, and DELETE operations.

Middleware in nest is similar to that of express, all the working principle is the same. The only difference that is seen is that in express middleware is made as a function, in nest middleware is made as a class that implements the NestMiddleware interface.

Node JS middleware functions provide all the access for requesting, responding to, and moving to the next middleware function in the request-response cycle of an application. Simply understanding, middleware is something that is present in between the request and response cycle which perform a certain task on the basis of which the next step is determined.

In this, you’ll get to learn how to create and deploy the awslambda function with Terraform. With Terraform, it is much easier and more efficient to create and deploy the lambda function on AWS.
