微信小程序拆包

微信小程序本身打包体积有 2M 的限制。微信官方提供了小程序分包的方法，主包和分包每个不能超过 2M，加一起不能超过 8M。

具体方法：

{
    "pages": [
        "pages/newIndex/index",
        "pages/news/index",
        "pages/index/index",
        "pages/my/my",
        "pages/index/search/index",
        "pages/index/searchMore/index",
        "pages/index/searchParts/index",
        "pages/index/searchMinifigs/index",
        "pages/index/searchClassify/index",
        "pages/index/set/index",
        "pages/index/bannerDetail/bannerDetail",
        "pages/index/set/setDetail/index",
        "pages/index/set/partMinifigs/index",
        "pages/index/set/partMinifigsDetail/index",
        "pages/index/set/bigPartsDetail/index",
        "pages/index/set/shop/index",
        "pages/my/myHistoryCollect/index",
        "pages/login/telphone/telphone",
        "pages/picture/detail/index",
        "pages/activity/bill/index/index"
    ]
}

以上是旧的版本，可以看到页面非常多，所有页面都是pages下面，最终打包出来的体积也非常大。

经过优化，我们把非入口页面 移到 单独目录packageSub下

{
    "pages": [
        "pages/newIndex/index",
        "pages/index/index",
        "pages/my/my",
        "pages/login/login",
        "pages/login/telphone/telphone",
        "pages/activity/bill/index/index"
    ],
    "subPackages": [
        {
            "root": "packageSub",
            "pages": [
                "shop/index",
                "shop/shopDetail/index",
                "shop/shopCar/index",
                "shop/payPage/index",
                "shop/remark/index",
                "shop/rate/index",
                "community/index",
                "community/sendCommunity/index",
                "community/sendComment/index",
                "community/detail/index",
                "my/myHistoryCollect/index",
                "news/index",
                "offline/offline"
            ]
        }
    ]
}

文件目录页面变化:

注意 别忘了修改老的 wx.navigateTo 方法的路径
