Question

I'm trying to host a simple index.html file in firebase but when I type firebase deploy its gives me the following error:

No targets found. Valid targets are: database,storage,functions,hosting. hosting error image

I found my firebase.json file is empty it contains only { } .

run firebase init and if your firebase.json is empty with only {} then add

 {
  "hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ]
  }
}

replace "public": "app" with "public": "public"

then run firebase deploy
