gulp打包vue3+jsx+less插件

最终转换结果如下

在根目录下添加gulpfile.js文件，package.json添加命令npm run gulp

var gulp = require('gulp')
var babel = require('gulp-babel')
var less = require('gulp-less')
var del = require('del');
var spawn = require('child_process').spawn;const outDir = "dist/"function es6toes5() {return gulp.src('packages/**/*.js').pipe(babel({presets: ["@babel/preset-env"],'plugins': [() => {return {visitor: {ImportDeclaration(path, source) {console.log(path);if (path.node.source.value.endsWith('.less')) {path.node.source.value = path.node.source.value.replace(/\.less$/, '.css')}},},}}]})).pipe(gulp.dest(outDir ));
}// function jsxtojs1() {
//   return gulp.src("packages/**/*.jsx").
//     pipe(babel({
//       plugins: [
//         ['@babel/plugin-transform-react-jsx', {
//           "throwIfNamespace": false,
//         }
//         ]
//       ]
//     })).
//     pipe(gulp.dest(outDir ));
// }
function jsxtojs() {return gulp.src("packages/**/*.jsx").pipe(babel({plugins: [['@vue/babel-plugin-jsx',{enableObjectSlots: false,},],],})).pipe(gulp.dest(outDir ));
}function lesstocss() {return gulp.src('packages/**/*.less').pipe(less({relativeUrls: true,})).pipe(gulp.dest(outDir ))
}function npmTask(cb) {spawn('npm.cmd', ['run', 'lib'], {}) // 'npm.cmd' : 'npm' 运行 npm run lib .on('error', cb).on('close', code => code ? cb(new Error(code)) : cb());
}exports.default = gulp.series(() => del([`./${outDir}/**`]),npmTask,jsxtojs,es6toes5,lesstocss);

打包后的结果
