As our system grows, certain queries on our database might fail us in terms of performance. One of the popular ways of dealing with this issue are indexes. This article explores how we can use them both through TypeORM and writing our own Postgres queries. Introduction to indexes When we store information on a disk, […]
The debugging process is not always easy, and the bugs are sometimes difficult to track down. Fortunately, Git provides us with tools that might make this process easier. In this article, we learn both the worktree and bisect tools. Git Worktree Sometimes, when we focus on a new feature, a bug pops up in production. Unfortunately, this […]
Handling forms manually is not difficult in React. Keeping all of the code consistent in your project might be quite a hassle, though. There are many ways in which we can tackle the state of our forms and validation. We can expect the approach of our teammates to differ slightly. To manage our forms better, […]
With React, we have quite a few options when it comes to state management. One of the most obvious ones is using the local state. Unfortunately, it might lead to prop drilling. It happens when we pass data from one component through many layers. When some of the components along the way do not need the […]
In the third part of this series, we’ve implemented authentication with JWT, Passport, cookies, and bcrypt. It leaves quite a bit of room for improvement. In this article, we look into refresh tokens. You can find all of the code from this series in this repository Why do we need refresh tokens? So far, we’ve implemented JWT […]
So far, we’ve covered a few different tools useful when rewriting the Git history, such as merging and rebasing. In this article, we go more in-depth and try cherry-picking. While doing so, we also learn how the reflog functionality works. Git Cherry Pick When we rebase or merge, we usually get all of the content of […]
We can find some searching functionalities in a lot of web applications. While we might be fine when iterating through a small data set, the performance for more extensive databases can become an issue. Relational databases might prove to be relatively slow when searching through a lot of data. A solution to the above problem […]
The serverless approach to building applications is getting more and more popular. It might be appealing to write and deploy code without worrying about the infrastructure underneath. Serverless computing still involves servers. The provider takes care of their maintenance entirely, though. We write event-driven functions that contain business logic. The provider charges us solely based […]
In the previous part of this series, we’ve looked into how rebase can improve our merges. It is a lot more powerful, though, and can come in handy in other situations. In this article, we explore how to perform interactive rebasing. Introduction to the interactive rebase tool When doing an interactive rebase, we can modify existing […]
The creation of software usually takes place across multiple iterations, and our code changes often. Because of that, we need a way to describe this process with the use of versions. There are quite a few ways to do that. Recently the most widely adopted approach seems to be semantic versioning. It involves a sequence of […]
