Build Vue3 TSX mobile terminal project based on Vue Cli4 (1)

Build Vue3 TSX mobile terminal project based on Vue Cli4 (1) Project Description It has been nearly a year since the release of the preview version of Vue3. In previous experiments, compared with React Hooks, when targeted optimization is not considered, the underlying rendering mechanism of Vue3 is optimized better. So it's time to start some experiments with Vue3. because I feelVue Cli4It is very mature, so there is no need to build Webpack from scratch. It will be more efficient to repackage

Create a lightweight responsive state management library from scratch [observable-lite]

Preface/Introduction The last article created a state management library based on rxjs, and the article link is here to build your own state management library based on Rxjs . However, during the development process, it was found that the observable-store library has performance problems when processing large json data. When collecting historical state or setState, there are a large number of deepcopy operations. The performance difference in small objects will not be so obvious, but large json

Vue2 migrated to Vue3.0.5, <srcipt setup> development to deployment guide to avoid pits

begin Vue3 has been out for a while. Recently, the company has a project that needs to be refactored. I refactored it with Vue3. In terms of development experience, I personally feel that the change is not very big, but I must say that vite is really fast. I encountered it during the development process. There are also a lot of problems, especially when deploying. If you don't read the document carefully, you will need to GG. Don't talk nonsense, just go to the topic. Project structure vue3.0.5

Serverless basic concepts and principles interpretation

idea In the novel "Three-Body", the scene of the internal facilities of the future spacecraft is depicted. When the technology is highly developed, the complex details of the facilities are hidden. No shadow of any facilities can be seen inside the spacecraft, but when it is necessary to use it, There will be seats, tables and other facilities for people to use. Similarly, Serverless is also a concept. It hides the details of complex service operation and maintenance and physical facilities insi

[Translation] Personal Development for Smart People Chapter3 Power

The most powerful person is the one who can control himself. SENECA Strength is the third principle of personal development. It is your innate ability to consciously change the world around you. When you are weak, you cannot meet your needs and desires, and you become a victim of the environment; when you are strong and successfully create the life you want, your surrounding environment will also reflect this fact. For some people, power is a dirty word, and it is always associated with the neg

Original link: tecdat.cn/?p=9997 Original source: Tuoduan Data Tribe Official Account Introduction to k-medoids clustering k-medoids is another clustering algorithm that can be used to find groups in a data set. k-medoids clustering is very similar to k-means clustering, except for some differences. The optimization function of k-medoids clustering algorithm is slightly different from that of k-means. In this section, we will study k-medoids clustering. k-medoids clustering algorithm There are m

The basis of the front-end data structure and algorithm graph

Graph concept To quote the description of Wikipedia: In the branch graph theory of mathematics, Graph is used to express the relationship between objects and it is the basic research object of graph theory. A graph consists of small dots (called vertices or nodes) and straight lines or curves (called edges) connecting these dots. The English mathematician Sylvester first proposed the term "graph" in 1878. It can be seen from the above that we learn the data structure of graphs, which is part of
