I was using rollup to build it. \r\n\r\nSo I checked some examples on the vue-demi repo and discovered that everybody was using render and h to build templates, I switched to render function and everything seems to work nice, except that the first guy using it, was using vue2 and had some errors, after some checking I found out that the h function as different behaviours if used in vue2 and vue3 (I've never used render functions before :D)\r\n\r\nTo fix the issue I made a wrapper to the h function ([h-demi.ts](https://github.com/UnevenSoftware/vue-insta-stories/blob/main/packages/lib/src/utils/h-demi.ts)) basically the function has the same interface as vue2 createElement, and if you are using vue3 it adapts the arguments to the h function.\r\n\r\nThe version of h-demi.ts that I've written is pretty simple, it covers only what I used in vue-insta-stories, and is missing a lot of typings.\r\n\r\nI was wondering if a more robust version of h-demi would be a \"nice to have\" feature inside vue-demi or vue/composition-api. That would help a lot of people that want to build a library and make it compatible with both 2 & 3 versions of vue.\r\n\r\nThat was my first approach to a library, I may also got the whole building process wrong, but I didn't found examples or really good guides, so i mixed up what I've found (if there is an another way of fix the render issues please tell me \u003C3)",[],65,"h-demi - `h` function for Vue 2 and 3","2021-07-15T17:18:20Z","https://github.com/vueuse/vue-demi/issues/65",0.714844,["Reactive",2951],{},["Set"],["ShallowReactive",2954],{"$fTRc1wZytZ_XrK4EfJfei_Sz-An4H4Yy6syhVxH_PVJc":-1,"$f5AxltqDIrraly1DgLL9JUqX-Z07RKq-r8RjVArvBN30":-1},"/vueuse/vue-demi/137"]
