typesense-instantsearch-adapter is unfriendly for pure Javascript/ReScript projects

[sprkv5]

Description

npm install typesense-instantsearch-adapter provides a dependency that has index.js missing.
This should be fine for TypeScript projects. For pure JavaScript/ReScript projects,
attempting to build the example results in the following error:

var adapter = new TypesenseInstantsearchAdapter(config);
^

TypeError: TypesenseInstantsearchAdapter is not a constructor

Steps to reproduce

1. mkdir typesense-demo && cd typesense-demo
2. npm install typesense-instantsearch-adapter
3. Copy and paste the JavaScript example from : https://typesense.org/docs/guide/search-ui-components.html#walk-through

    // index.mjs -- since we're using ESM
    import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";

    const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
    ...

4. node index.mjs

    file:///C:/Users/User/Projects/typesense-demo/index.mjs:3
    const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
                                          ^

    TypeError: TypesenseInstantSearchAdapter is not a constructor
    ...

Expected Behavior

index.mjs file should run without error

Actual Behavior

I find the following error:

    file:///C:/Users/User/Projects/typesense-demo/index.mjs:3
    const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
                                                                    ^

    TypeError: TypesenseInstantSearchAdapter is not a constructor
    ...

because index.js is missing in the dependency here:
node_modules/typesense-instantsearch-adapter/index.js

+1, did you ever manage to solve this?

For now, I managed to get it to work with
import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter/src/TypesenseInstantsearchAdapter"; instead of import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";

@jhotujec That solution doesn't work for me. I get this error now instead:

2023-06-05 13:55:52 (node:139) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.

@eminos not sure, I used it like this and it works

import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter/src/TypesenseInstantsearchAdapter";

const searchAdapter = function (searchParams = {
  query_by: "title",
}) {
  const qtypesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
    server: {
      apiKey: "<your-api-key>",
      nodes: [
        {
          host: "<your-host>",
          path: "",
          port: "443",
          protocol: "https",
        },
      ],
      cacheSearchResultsForSeconds: 0,
    },
    additionalSearchParameters: searchParams
  });
  return qtypesenseInstantsearchAdapter.searchClient;
};

export default searchAdapter;
