coolie 2.5.0 扩展日记

用coolie很多年了,非常感谢云大神提供这么好的工具,闲暇之余,对其稍作修改,支持构建vue文件

一个vue文件包含template, style, scrip 三个部分,本方案输出格式如下

构建前

<template>
    <div class="less-scoped">
        <p class="red">{{aaa}}</p>
    </div>
</template>

<script>
    exports.default = {
        data(){
            return {
                aaa : 123
            }
        }
    }
</script>

<style lang="less">
.less-scoped{
    .red{
        color : red;
    }
}
</style>

构建后,做了美化

/*coolie built*/
define("0", ["3"], function (e) {
    return e("3")
});
define("3", [], function (require, exports, module) {
    exports.render = function () {
        with(this) return _c("div", {
            staticClass: "index-user"
        }, [_c("p", {
            staticClass: "red"
        }, [_v(_s(aaa))])])
    };
    exports.staticRenderFns = [];
    exports.moduleid = "index-user";
    exports.style = ".index-user .red {\n  color: red;\n}\n";
    exports["default"] = {
        data: function () {
            return {
                aaa: 123
            }
        }
    }
});

如您所见 支持es6,less构建(没研究过官方的方案) 然后自己再封装一个loadVue的方法,将上面的对象改成vue所需的格式即可

下面说下修改方案: coolie-cil
