Issues with Typesense.Client in React Native

TLDR kurt is experiencing issues with Typesense.Client instantiation in React Native, despite correct imports and code. Jason couldn't identify immediate issues, but agreed to troubleshoot with a simplified reproduction app.

Hi all! Has anyone gotten this to work with React Native? I’m building an app with Expo, using React Native code, and when I’m just trying to instantiate Typesense and assign a variable to the Typesense.Client, i get the error: "TypeError: Cannot read property 'Client' of undefined".

I just try to get the client like in Step #2 of the Firebase docs

It should technically work with React Native, but I haven’t tried it myself.

In this case, did you already import or require the Typesense library?

kurt

04:49 PM

Yes, definitely did that

Jason

Hmmm, could you share the full code snippet you’re using?

Oh also, have you added it to package json, npm install, etc?

Above my screen component, it basically looks like this for now, just to try to see some results:

import React, { useEffect, useLayoutEffect, useState } from 'react';
import { HeaderBackButton, StackScreenProps } from '@react-navigation/stack';
import Typesense from 'typesense';

type ScreenProps = StackScreenProps<AppStackParamList, 'Explore'>;



let searchClient = new Typesense.Client({
    nodes: [
        {
            host: '', 
            port: '443',
            protocol: 'https'
        }
    ],
    apiKey: 'my-api-key',
    connectionTimeoutSeconds: 2
});

export default function ExploreScreen({ navigation, route }: ScreenProps) {
...
}

If you can’t see anything wrong with that, maybe i have to make a minimal reproducible app

and yeah, typesense is installed with:

typesense": "^0.14.0,

Jason

Yeah I can’t see anything immediately wrong with it, but then I’m also not too familiar with React Native. If you can give me a minimal app to reproduce this in, I can take a closer look

kurt

yeah, it doesn’t seem much like a React Native error though but something else more rudimentary to js, but i’m not really sure. I did install @babel/runtime too. Thanks for the quick replies in any case!

On a side note, i was a little confused by the docs there, since, about the Firebase Extension (which I’m using) at the top of the doc, it states:

If you choose to use this extension, you can skip directly to Step 4 below, once you set up the extension.

and then at Step 4, the code shows to use client variable, but not showing how to get the client.

so I’m assuming it’s the same as in Step 2.

Ah yes it is. Good catch, will fix that
