Instantsearch is not a function error ( on initialization )

Hi there,
We have an issue getting instantsearch.js to start up (initialize) within a Vue component - getting the following console error:

[Vue warn]: Error in mounted hook: "TypeError: instantsearch is not a function"

found in

---> <KAlgSearchMainCourse> at /Users/cb/Documents/projects/kee/resources/assets/js/components/kee/algCourseMain.vue

I’m following the guide here

In the Vue component the cause of the errors I believe are:

const instantsearch = require('instantsearch.js');
// ... and later on
mounted() {
    const search = instantsearch({ // ...

Is there something I should be aware of in using vue components in this way do you know?

Here’s the full Component code:

      <p>Test content vue is outputting data as expected:</p>


const instantsearch = require('instantsearch.js');

export default {
  data() {
    return {
      msg: "data string output from Vue"
  mounted() {

    const search = instantsearch({
        urlSync: true,
        searchParameters: {
            hitsPerPage: 5, // best to match an option in Pagination array
            attributesToSnippet: ["snippet:35"],
            snippetEllipsisText: "..."



and here’s package.json in case it gives up any clues.

        "axios": "^0.15.3",
        "baguettebox.js": "^1.9.1",

Thank you for taking a look.

Sorry all, simple fix:

// const instantsearch = require('instantsearch.js');
import instantsearch from "instantsearch.js";

We have a similar problem. We are using Laravel with Laravel-Mix and Webpack.
We are using instantsearch.js 2.0.2 and if we upgrade to actual version 2.8.* we ware getting the error:
“TypeError: instantsearch is not a function”
We are using npm with window.instantsearch = require(‘instantsearch.js’); in our app.js
I have no idea what i can do, that it will work :frowning:
