How To Dev

Introduction This is a comprehensive page about the technologies I have shared in series format. You can view brief introductions and links to directly access each series you are interested in. In the field of software development, to deploy a product from the initial idea to its release, the standard process typically involves several stages as follows: Database : Designing and implementing the database according to business requirements, storing data during the system's operation. Backend : Handling the main logic of the system, communicating with the database and services. Frontend : Building the interface for users to interact with the system, which could be a desktop, mobile, or web application. This usually includes implementing UI/UX and integrating APIs from the backend. DevOps : Deploying the system for use, which can be done on a server or in the cloud. Testing : Applying testing methods to ensure the product meets the standards for release. Of course, these are just stan...

Introduction imgproxy is an efficient image processing and optimization service, featuring fast processing speeds, high security and low memory footprints because it is written in Go. The prominent advantages of imgproxy include the ability to resize, crop, compress and flexibly convert image formats (such as to WebP, AVIF) via URL. Notably, this service supports secure URL signing using HMAC encryption, which prevents DDoS attacks or unauthorized modifications of image size parameters from the client side. Although the NextJS Image component already supports automatic image resizing, it presents several limitations if you choose it for large-scale deployment Resized images stored in the cache of the .next folder only exist within a single NextJS server instance, making it difficult to share the cache when scaling up to multiple instances After building the project, the cache data is lost, or if you find a way to persist these resized images, a large dataset will still consume too much...

Introduction Bun is a modern JavaScript runtime built with the goal of optimizing performance and improving the development experience. In addition to being compatible with the NodeJS ecosystem, Bun also integrates a package manager, bundler and test runner in the same tool. Some outstanding advantages of Bun: Dependency installation speed is significantly faster than npm, yarn and even pnpm. High startup and application execution performance thanks to being written in Zig. Integrates multiple tools in one runtime, helping reduce the number of dependencies required. Supports projects using modern frameworks like NextJS and NestJS well. Helps shorten build times and optimize the CI/CD process. Detail Note that although using Bun can provide comprehensive and effective support for NPM packages, there are still many risks regarding compatibility with older package versions. If the project you are developing is relatively large and has been operating for a long time, consider carefully bef...
