JWT and Passport JWT Strategy for your NestJS REST API Project
NestJS offers us the solo @nestjs/jwt module that allows us to integrate JWT in our project.
The Passport package is a massively used NodeJS library, whose “sole purpose is to authenticate requests, which it does through an extensible set of plugins known as strategies.
Here is a detailed post of how you can implement them in your project.

NestJS: Use a solo @injectable class as a singleton Provider
NestJS Modules are Singletons by default. Their Providers are also singletons when they are provided from within the same module. However, there are cases where we want to use just a single solo class as provider to a couple or more modules. In such cases we can use the solo class as singleton or not. Let’s see how we can do that.

NestJS REST API: class-validator & class-transformer
In this post we will try to focus on how to start implementing the class-validator and class-transformer libraries. Both of them are widely used tools for validating REST API Requests’ data and/or transform your API Responses before to send them back to the client.
MongoDB schema validation rules
MongoDB is a very popular free and open-source cross-platform document-oriented database. It is a NoSQL database and it is based on JSON-like documents. Document-based databases are either schema-less or they provide a certain level of flexibility defining schemas using schema validation rules.
The purpose of this post is to demonstrate how we can apply some schema validation rules in a collection.
git: Commonly used commands
This is simply a reference list of some of the basic yet commonly used git commands. For further details, you can always refer to git documentation.
Step ahead fast, with NestJS environment configuration
NestJS provides the necessary documentation for working with different environments (development, production, etc.) using external configuration files and environment variables. So, if you have already taken a look there, then the below provided cases, will give you a hand to start implementing your (relatively simple) project as well.
NestJS: Avoid Circular Dependency issues
A circular dependency occurs when two classes depend on each other. For example, class A needs class B, and class B also needs class A. Circular dependencies can arise in Nest between modules and between providers.
Here, you can get a nice grasp on how you can avoid the Circular Dependency in Nest.js.
gh – GitHub Command Line Tool
This is a short intro for the gh -the GitHub Command Line Tool. Prior to the gh introduction, most of the job, working with terminal and trying to automate somehow the interaction with GitHub repositories, required the using of other CLI tools like curl. This was not such a handy approach, especially for DevOps. But now, we can rely on the gh tool that simplifies quite a lot, the automation of operations needed to deal with GitHub repos.
Typescript: Start a browser-based project (System.js)
If you want to start playing with Typescript and you are looking for a quick way to implement a simple Typescript project that it runs just in a browser, then this post enlightens a bit about this process.
