Node GET by ID API - node.js

Question

I have follow the instructions to create a NODE API here.
I'm trying to have a few endpoints with a NODE app to serve data to my React UI.
The database is mongodb where I have a collection for 'stores'.
I have 2 GET calls:
One to retrieve all stores
One to retrieve a store by ID
Node app.js:
app.get('/viewstores', (request, response) => {
storesCollection.find({}).toArray((error, result) => {
if (error) {
return response.status(500).send(error);
}
response.send(result);
});
});
app.get("/viewstores/:id", (request, response) => {
storesCollection.findOne({ "_id": new ObjectId(request.params.id) }, (error, result) => {
if(error) {
return response.status(500).send(error);
}
response.send(result);
});
});
I make my API calls from axios in React.
If I make a call to the first API to retrieve all stores, there no problem at all, but if I try to make the API call by ID, I still get all stores from the first API.
It seems that I am not able to target the GET by ID api.
React app
React.useEffect(() => {
axios.get('http://localhost:5000/viewstores', {
params: { _id: params.storesid}
})
.then(({data}) => {
console.log("DATA ==> ", data)
})
.catch(error => console.log("ERROR API GET ==> ", error))
}, [])
MongoDB store sample:
_id: ObjectId("12345")
businessname:"ABC"
businessaddress:"address abc 1"
Any idea why when I try to call the GET by ID I always get back the whole collection?
Thanks in advance.
Joe.

Assume params.storesid is 12345,
your current React code sends requests to http://localhost:5000/viewstores?_id=12345, and the route /viewstores is reached. To reach the /viewstores/:id route, the URL should be something likes http://localhost:5000/viewstores/12345 then Express will capture the 12345 part in the URL to request.params.id. You can try the code below:
React.useEffect(() => {
axios.get(`http://localhost:5000/viewstores/${params.storesid}`)
.then(({data}) => {
console.log("DATA ==> ", data)
})
.catch(error => console.log("ERROR API GET ==> ", error))
}, [])
You can read about Express route parameters in the official document.
