1. Introduction to WebAssembly Cross-platform: it can run on any platform that supports WebAssembly, including web browsers, servers, and mobile devices High performance: it uses a compact binary format that can be loaded and parsed quickly in the browser, improving application performance Security: it uses a sandbox model that isolates the code running inside it, protecting the system from malicious code

As the data volume exploded, the system responded very slowly. We carried out a series of optimizations on the application, and the system’s response time improved by an order of magnitude. Overall, optimizations in file compression and faster network access gave a noticeable boost to frontend performance, while optimizations in stored procedures, caching, and logic code gave a noticeable boost to backend performance.

I have been optimizing a project recently. After mapping out the whole chain, I started improving it step by step and found many points that could be improved. What follows are some thoughts on the development model and the deployment approach. I hope they give you some inspiration. 1. Development Background 1.

1. Installing node-sass When installing node-sass, the node scripts/install stage downloads a .node file from github.com, and network problems often cause this to fail. You can add an .npmrc file inside the project to configure a proxy for the installation: 1 2 sass_binary_site=https://npm.taobao.org/mirrors/node-sass/ registry=https://registry.npm.taobao.org Or install with cnpm: 1 2 npm install -g cnpm --registry=https://registry.
