JSON server and custom routes

Question

I'm using JSON server. If I initialize it with npx json-server --watch database.json --port 5000 and then open http://localhost:5000/items I can see all the items. If I go to http://localhost:5000/items/1 I have only one item. My question is - how can I change single item route so I get the first item by entering http://localhost:5000/items/myCustomId1? In other words, how can I replace id with customId?

{
  "items": [
    {
      "id": 1,
      "customId": "myCustomId1",
      "name": "Item 1"
    },
    {
      "id": 2,
      "customId": "myCustomId2",
      "name": "Item 2"
    }
  ]
}

I think the best you can do here is using parameters handling for that request. For instance, you can do http://localhost:5000/items?myCustomId=1 in your case. This will probably list all the items with customId of 1 instead of just 1 item (since customId is not unique in this case).
