How to better encapsulate axios requests: anti-shake interception, non-sensitive refresh token, baseUrl configuration of each environment, etc.
Foreword Let’s first look at common encapsulation requests and usage methods: 1. Create a new request.js with the following content: import axios from ‘axios’ const service = axios.create({ baseURL: ”, timeout: 3000, headers: {} }) service.interceptors.request.use( config => { // Here are some processing logics such as adding token, determining login permissions, etc. return config […]
How to accurately master the use of function anti-shake and function throttling?
Preamble Function debouncing (Debouncing) and function throttling (Throttling) are both technologies used to control the execution frequency of functions. They are usually very useful when processing high-frequency triggered events (such as window scrolling, mouse movement, input box input, etc.) 1. Core concepts Function anti-shake The core idea of function anti-shake is that when an event […]

Mtk camera QuickSwitch adds “anti-shake” switch icon
The mtk native camera already has an “anti-shake” switch in the settings. The customer wants to add a “switch” to the QuickSwitch bar, similar to the location of the flash icon ** Let’s take a look at the renderings first: #The function implemented is to add an anti-shake icon switch. The switch will be synchronized […]
js performance optimization: thoroughly understand function anti-shake and function throttling
Function anti-shake and throttling Function anti-shake and function throttling: A means to optimize high-frequency execution of js code. When some events in js, such as browser resize, scroll, mousemove, mouseover, and input box keypress, are triggered, they will Continuously calling the callback function bound to the event greatly wastes resources and reduces front-end performance. In […]
