Upgrade to latest version of npm packages in a Javascript app like React

The need for a upgrade?

Any library comes with upgrades to the functionality like security patches, functional improvement, performance tuned and new functionality added to accommodate the latest changes in the underlying language (in this case, it is Javascript)

Also, these days there are lot of CVE (vulnerabilities) reported in many libraries so it is always good to upgrade and be on the latest version so as not to compromise the application.

Also new functionalities / features brings in good chance for the dev team to learn and also write less and build more, so its a happy path always :)

Steps to Upgrade

1. Install the npm-check-updates package through the below command

npm install -g npm-check-updates

2. Ensure that the package.json file is having a back-up or in source control like git, to be safe to make sure that we can revert back to the older one in case of troubleshooting any issues / incompatibilities in the new versions.

3. run the below command that scans the `package.json` file and then does the upgrade to the newer versions

ncu --upgrade

4. now, Install the upgraded ones using the below command

npm install

This should bring all the new version of dependencies to the project. Validate all the functions thoroughly in the local environment and then deploy to DEV / QA and once certified, production deployment can be made.

User Authentication schemes in a Multi-Tenant SaaS Application

User Authentication in Multi-Tenant SaaS Apps Introduction We will cover few scenarios that we can follow to perform the user authentication in a Multi-Tenant SaaS application. Scenario 1 - Global Users Authentication with Tenancy and Tenant forwarding In this scheme, we have the SaaS Provider Authentication gateway that takes care of Authentication of the users by performing the following steps Tenant Identification User Authentication User Authorization Forwarding the user to the tenant application / tenant pages in the SaaS App This demands that the SaaS provider authentication gateway be a scalable microservice that can take care of the load across all tenants. The database partitioning (horizontal or other means) is left upto the SaaS provider Service. Scenario 2 - Global Tenant Identification and User Authentication forwarding In the above scenario, the tenant identification happens on part of the SaaS provider Tenant Identification gateway. Post which, the

Handling exceptions in the Executor service threads in Java

Introduction This is a continuation post on the exception handling strategies in the threads in Java. For Introduction, please read this post The second post is available here This post addresses the problem statement "How to use the exception handlers in the threads spawned by the Executor Service in Java?" Not all times, we will be using Thread classes to run our threads because we have to manage a lot of the underlying logic for managing threads. There is ExecutorService in Java which comes to the rescue for the above problem. In the previous posts, we have discussed on how to handle the exceptions in plain threads. However, when using executor service, we do not create / manage threads, so how do we handle exception in this case. We have a ThreadFactory as an argument which can be used to customize the way threads are created for use within the ExecutorService . The below snippet of code leverages this feature to illustrate the exception handling, wherein we create a

Download CSV file using JavaScript fetch API

Downloading a CSV File from an API Using JavaScript Fetch API: A Step-by-Step Guide Introduction: Downloading files from an API is a common task in web development. This article walks you through the process of downloading a CSV file from an API using the Fetch API in JavaScript. We'll cover the basics of making API requests and handling file downloads, complete with a sample code snippet. Prerequisites: Ensure you have a basic understanding of JavaScript and web APIs. No additional libraries are required for this tutorial. Step 1: Creating the HTML Structure: Start by creating a simple HTML structure that includes a button to initiate the file download. <!DOCTYPE html> < html lang = "en" > < head > < meta charset = "UTF-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1.0" > < title > CSV File Download </ title > </ head > < body >

Implementing Row Level Security [RLS] for a Multi-Tenant SaaS Application

Row Level Security The need for row level security stems from the demand for fine-grained security to the data. As the applications are generating vast amounts of data by the day. Application developers are in need of making sure that the data is accessible to the right audience based on the right access level settings. Even today, whenever an application was built, the application development team used to spend a lot of time researching the approach, implementing multiple tables multiple logics 25 queries to add filters to manage the data security for every query that gets transferred from the end user request to the application database. This approach requires a lot of thought process, testing and security review because the queries needs to be intercepted, updated and the data retrieval to be validated to make sure the end-users see only the data that they are entitled to. Implementation With the advent of of row level security feature being rolled out in main d
