Guide to Initializing and Connecting AWS DynamoDB

Image
Introduction Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability at any scale. Key benefits include: unlimited scalability, extremely low latency in milliseconds, built-in security, and flexible pricing models based on usage (On-demand) to optimize costs. Detail Use AWS CDK to create the lib/dynamodb-stack.ts file import * as cdk from "aws-cdk-lib" import * as dynamodb from "aws-cdk-lib/awsf-dynamodb" import { Construct } from "constructs" export class DynamodbStack extends cdk . Stack { constructor ( scope : Construct , id : string , props ?: cdk . StackProps ) { super (scope, id, props) const productTable = new dynamodb. Table ( this , "ProductTable" , { tableName: "Products" , partitionKey: { name: "id" , type: dynamodb.AttributeType. STRING , }, billingMode: dynamodb.Bi...

Guide to deploying NextJS on AWS ECS

Image
Introduction I already have an article guiding the deployment of a project using the NestJS framework on AWS ECS, while in this article we will go through how to deploy a frontend project using the NextJS framework also deploying on AWS ECS, the difference is mostly concentrated in building the docker image, as long as you can build the docker image and push successfully to AWS ECR, the next steps are almost identical Prerequisites Because there was a previous article providing quite comprehensive guidance on AWS ECS, in this article I might not instruct in detail about it much more, if there is any information that is not clear you can review previous articles to understand better The goal of the article is to concentrate on the deployment so I will not dive deep into coding NextJS but will reuse from previous articles, you can also use a similar project according to your own needs Detail First of all, let's update the next.config.ts file to support standalone mode import type {...

Revoking JWT with Redis in NestJS

Image
Introduction In the previous article, I provided instructions on using NestJS with JWT, and you may also realize that if you use JWT, once a token is issued, it cannot be revoked. This means that if you have a token that hasn't expired yet, you can continue to use the service. For small systems that do not prioritize security, this might not be a major issue and can be simply resolved by deleting the token from the frontend when the user logs out. However, if you need to build a system with extremely high security, where the token must be invalidated upon logout so that no one can use it to access the service, this article will guide you through how to achieve that. To do this, we will use Redis (which I have already guided you on in this article) to store tokens that have not expired but are requested to be deleted. The storage duration for these tokens will be exactly the time remaining until they expire. Thus, after applying Redis, the operation of tokens will be as follows: If ...
