Why do I find that every time I build a hot compilation is different, but this time should be considered the most scientific way. webpack.config.js only need to pay attention to increase the thickness of the place. This is the core, and the rest is just a demonstration of the actual situation.varWebpack = require ("Webpack");varHtmlwebpackplugin = require (' Html-webpack-plugin ')); Module.exports={entry:{JQ: [__dirname+ '/src/js/jq/jquery-1.9.1.js ', __dirname+ '/src/js/jq/jquery.urianchor-1.1

Recently learning a VUE-CLI project requires data interaction with the background, where local JSON data is used to mimic the background data interaction process. However, there is no dev-server.js file found under the build folder because the new version of Vue-webpack-template The dev-server.js has been removed and replaced by the Webpack.dev.conf.js file, so local access can be configured in Webpack.dev.

Some people think that the background daemon to do this kind of redirection operations waste resources, we recommend that the 0, 1, 2nd sentence directly closedHandle down, which is very incorrect.

In my recent project, I need to use JNI to call C/C ++ compiled programs. Since I was not familiar with JNI, I found many of them on the Internet are implemented based on the VC or vs2008 series. In this way, it is very troublesome to install hundreds of megabytes of VC or several GB of vs for a simple call, because I have been using Dev C ++ for C Development (this Dev is very compact and powerful, but it
