使用gulp构建项目,sass/less编译,js/css/html/image压缩,版本号处理

作者:互联网

gulp是一个基于任务的工具

gulpfile.js

const gulp = require('gulp');
const sass = require('gulp-sass')(require('sass'));//将scss编译成css
const browserSync = require('browser-sync');//微型服务,当资源改动时,浏览器会自动刷新
const minifycss = require('gulp-minify-css');//css压缩插件
const uglify = require('gulp-uglify');//js压缩插件
const changed = require('gulp-changed');//只编译更改过的文件
const htmlmin = require('gulp-htmlmin');//压缩html文件
const del = require('del');//删除文件
const revFormat = require('gulp-rev-format');//xx.css格式化成xx.8ac2s2jz.cache.css形式
const rev = require('gulp-rev-dxb');//生成需要版本替换的静态资源清单
const revCollector = require('gulp-rev-collector-dxb');//将生成好的静态资源清单替换到html文件中
