[Noob Question] Can't import ClapDetector from 'clap-detector'

[B-Bimmermann]

Hi,

I try to use jour Libary, but I'm realy new to node js.
So maybe this is a normal beginner question, but I don't found anything on "google" that matches my problem.

I use a Raspberry Pi 4 with a USB-Micro. I use the normal Raspberry Pi console os.

I have then update the OS and have done the folling steps:

sudo apt-get update ; sudo apt-get update -y ; sudo apt-get install sox;
sudo apt-get install nodejs npm
curl https://www.npmjs.com/install.sh | sudo sh
mkdir new_clap_npm; cd new_clap_npm;
npm install --save clap-detector
touch clap.js

This creates the folling in new_clap_npm:
drwxr-xr-x 3 pi pi 4096 Jul 21 12:46 . drwxr-xr-x 11 pi pi 4096 Jul 21 12:43 .. -rw-r--r-- 1 pi pi 1067 Jul 21 12:47 clap.js drwxr-xr-x 5 pi pi 4096 Jul 21 12:45 node_modules -rw-r--r-- 1 pi pi 58 Jul 21 12:45 package.json -rw-r--r-- 1 pi pi 1888 Jul 21 12:45 package-lock.json

I have then copy this into clap.js:

`import ClapDetector from 'clap-detector'

const clap = new ClapDetector()
const disposableOneClapListener = clap.addClapsListener(claps => {
console.log("heard 1 clap (force)", claps)
}, { number: 1, delay: 0, force: true })

const disposableOneClapForceListener = clap.addClapsListener(claps => {
console.log("heard 1 clap", claps)
}, { number: 1, delay: 1000 })

const disposableTwoClapsListener = clap.addClapsListener(claps => {
console.log("heard 2 claps", claps)
}, { number: 2, delay: 1000 })

const disposableThreeClapsListener = clap.addClapsListener(claps => {
console.log("heard 3 claps", claps)
}, { number: 3, delay: 1000 })

// Cancel some clap listeners
// Cancel alls claps listener but 2 claps after 10 seconds
setTimeout(() => {
console.log("only listen to 2 claps now")
disposableOneClapListener()
disposableOneClapForceListener()
disposableThreeClapsListener()
}, 10000)

// Dispose (stop sox process and listeners) after 30s
setTimeout(() => {
console.log("dispose all listeners and free ressources")
clap.dispose()
}, 30000)
`

If I try now to start with: I get
`/home/pi/new_clap_npm/clap.js:1
import ClapDetector from 'clap-detector'
^^^^^^^^^^^^

Viso shows me this error on line 1:
Could not find a declaration file for module 'clap-detector'. '/home/pi/new_clap_npm/node_modules/clap-detector/lib/index.js' implicitly has an 'any' type. Try npm i --save-dev @types/clap-detectorif it exists or add a new declaration (.d.ts) file containingdeclare module 'clap-detector';ts(7016) module "/home/pi/new_clap_npm/node_modules/clap-detector/lib/index"

If I try to do the Viso fix I get:
`pi@raspberrypi:~/new_clap_npm $ npm i --save-dev @types/clap-detector

Please help me to import your libary.
