Build a Query in MuleSoft With Optional Parameters

In this tutorial we will see how to:

  • Define a RAML API specification to search products in a catalog database
  • Establish and configure a database connection to query a MySQL database
  • Build a query to support multiple optional filters
  • Add optional sorting capabilities to our query at DB level

1. Define the RAML of a Search API

Imagine that you want to create a MuleSoft API to search products inside a catalog. This API will need to accept multiple filter parameters and an optional sorting parameter. All these parameters can be optional and will be used to generate a dynamic query to search products in your catalog database.

Mule Standalone Runtime Setup and Deployment

When most of the integration data is lying inside an organization's data center and data is highly secured, then the On-Prem deployment model is the right solution.

It does offer the flexibility to set up your load balancing, domains, VPC, and anything you want to do to your environment as you will be building it in your own data center. You can cluster specific servers that you have in your infrastructure and set them accordingly.

Create a Custom Connector Using XML SDK and Deploy it in Anypoint Exchange

Introduction

XML SDK is an alternative approach to build custom modules in Mulesoft. This approach is comparatively easier to build compared to the already existing JAVA Mule SDK. Creating a custom module in Mule SDK is similar to creating a Mule application. This document is focused on demonstrating the steps to build a custom module using the XML SDK and deploying it in Anypoint Exchange. We will create a custom connector in Mule 4 that will perform basic arithmetic operations like addition and subtraction

Fine-Grained vs. Coarse-Grained APIs in MuleSoft

API design is a fascinating topic. One important aspect of API design is determining the right 'size' of an API in terms of its features and functionality. All architects must have grappled with this issue at some point or the other. In this article, I will try and give some insights into the various parameters that we need to think through before arriving at the 'right' grained API:

  • Maintainability: The first aspect that comes to mind is the maintainability of APIs. Coarse-grained APIs are difficult to maintain. As the API consumer needs grow, it will be difficult to add more implementation variations or parameters.
