Editor to share with you how to make layui support es5 writing, I hope you have something to gain after reading this article, let's discuss it together!

When writing js, I will write some es5 code, but when I package it to dist, I find that syntax is not supported. What should I do?

Add es5 support in two steps:

First, use npm to download and install babel and enter the directory where gulpfile.js is located.

$npm install-- save-dev gulp-babel @ babel/core @ babel/preset-env

Second, modify the gulpfile.js code in 2 places.

Var gulp = require ('gulp'); var babel = require (' gulp-babel') / / add this code / /... / / compress JS minjs: function () {/ / modify the following code return gulp.src (src) .pipe (babel ({presets: ['@ babel/env']})) .pipe (uglify ()) .pipe (header.apply (null, note)) .pipe (gulp.dest (destDir +'/ layuiadmin'));}

You can then type gulp as before to complete the build of the src to dist directory.
