Lambda is a Function-as-a-Service program of AWS. It has a lot of awesome features. We deployed some of our API’s that was
written in NodeJS to Lambda. In this article, I will share my experience of migrating frm Express also I will go through
the benefits and disadvantages of Lambda. Please note that, this article is not about introduction to Lambda rather than a review on it.
Migrating from Express to Lambda
There are several ways you can migrate from Express to Lambda. The fastest way is using aws serverless express node module.
But using this method creates some difficulties to manage API Gateway tool. When using Express in Lambda, API Gateway tool
lose the ability to manage individuals routes. It redirects all requests to Express.
API Gateway tools provides a lot of benefits for managing routes including Authorization, staging, documentation, and easy
to add, delete or rename the routes by button clicks.
