This is a tool for creating rule configuration for Firebase Realtime Database. You can design the rule easily by using the spread sheet (like MS Excel), and convert it to Firebase fule format.

Example

Designing rule with spread sheet like below,

and you can convert it to JSON below.

{
  "rules": {
    "users": {
      "$user": {
        ".validate": "newData.isString()"
      },
      "groups": {
        "$group": {
          ".validate": "(newData.isString()) && (newData.val().length > 5)"
        }
      },
      "name": {
        ".validate": "newData.isString()"
      },
      ".indexOn": [
        "name"
      ]
    },
    "groups": {
      ".read": "true"
    },
    "  users": {
      ".validate": "newData.isString()"
    },
    "devices": {
      ".read": "auth.uid !== null",
      ".write": "false",
      "$devices": {},
      "name": {
        ".validate": "newData.isString()"
      },
      ".indexOn": [
        "name",
        "valid"
      ],
      "version": {
        ".validate": "newData.getPriority() != null"
      },
      "valid": {
        ".validate": "newData.isBoolean()"
      }
    }
  }
}

  • READ
    • This will be used for '.read' directly

    • This will be used for '.write' directly

• Convert it with command below

(or you can use it in pipe)
