What is the process for importing from vueuse into Vue SFC Playground?

After attempting to integrate vueuse through an Import Map using the code

@vueuse/core": "https://www.unpkg.com/@vueuse/core?module
, I encountered an issue where reactivity was not functioning as expected in vueuse.

The import process appeared to be successful without any errors, but unfortunately, reactivity was not present.

play.vuejs.org

Answer №1

module parameter must have all Vue-related entries in the import map loaded from unpkg:

Transforms all “bare” import specifiers in JavaScript modules to unpkg URLs. This functionality is highly experimental.

This issue persists in this playground and leads to multiple instances of the vue library being loaded by @vueuse/core? from unpkg:

  "imports": {
    "vue": "https://play.vuejs.org/vue.runtime.esm-browser.js",
    "vue/server-renderer": "https://play.vuejs.org/server-renderer.esm-browser.js",
    "@vueuse/core": "https://www.unpkg.com/@vueuse/core?module"
  },

Having multiple copies of Vue can lead to loss of reactivity.

To address this, either update vue, etc to use unpkg, or avoid using ?module and properly add the dependency tree to the import map (see demo):

  "imports": {
    "vue": "https://play.vuejs.org/vue.runtime.esm-browser.js",
    "vue/server-renderer": "https://play.vuejs.org/server-renderer.esm-browser.js",
    "@vueuse/core": "https://www.unpkg.com/@vueuse/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fa9995889fbacbcad4c3d4ca">[email protected]</a>/index.mjs",
    "@vueuse/shared": "https://www.unpkg.com/@vueuse/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="cebda6afbcabaa8efffee0f7e0fe">[email protected]</a>/index.mjs",
    "vue-demi": "https://www.unpkg.com/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f5838090d89190989cb5c5dbc4c1dbc2">[email protected]</a>/lib/index.mjs"
  },
