best praticle to use the client from an google api-CodePudding

i'm using the google API, to be specific, the textToSpeech API. i made a function to do this conversion, in an separate archive. And this API require that i create an client.

import * as textToSpeech from '@google-cloud/text-to-speech'
const clientGoogle = new textToSpeech.TextToSpeechClient();

but now is my question: is better that i create this client outside the function or inside?

like this:

import * as textToSpeech from '@google-cloud/text-to-speech'

const clientGoogle = new textToSpeech.TextToSpeechClient();
const createAudio = async ()=>{
    const [response] = await clientGoogle.synthesizeSpeech(request);
}

import * as textToSpeech from '@google-cloud/text-to-speech'
    
const createAudio = async ()=>{
     const clientGoogle = new textToSpeech.TextToSpeechClient();
     const [response] = await clientGoogle.synthesizeSpeech(request);
}

what of this usage is better for my application?

CodePudding user response：

In general, you should create the client once in the global space. Then access the client member functions as required. Translation, use your first example.

However, I recommend referencing the package like this:

const textToSpeech = require('@google-cloud/text-to-speech');
