Ray Skill

Overview

Ray is Spatie's desktop debugging application for developers. Send data directly to Ray by making HTTP requests to its local server.

This can be useful for debugging applications, or to preview design, logos, or other visual content.

This is what the ray() PHP function does under the hood.

Connection Details

Setting	Default	Environment Variable
Host	`localhost`	`RAY_HOST`

Simple Payloads (No Content)

}

Type	Purpose
`separator`	Add visual divider

`hide`	Hide this entry
`remove`	Remove this entry
`confetti`	Show confetti animation
`show_app`	Bring Ray to foreground
`hide_app`	Hide Ray window

Combining Multiple Payloads

Send multiple payloads in one request. Use the same uuid to apply modifiers (color, label, size) to a log entry:

json

{
  "uuid": "abc-123",
  "payloads": [
    {
      "type": "log",
      "content": { "values": ["Important message"] },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    },
    {
      "type": "color",
      "content": { "color": "red" },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    },
    {
      "type": "label",
      "content": { "label": "ERROR" },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    },
    {
      "type": "size",
      "content": { "size": "lg" },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    }
  ],
  "meta": {}
}

Example: Complete Request

Send a green, labeled log message:

bash

curl -X POST http://localhost:23517/ \
  -H "Content-Type: application/json" \
  -H "User-Agent: Ray 1.0" \
  -d '{
    "uuid": "my-unique-id-123",
    "payloads": [
      {
        "type": "log",
        "content": {
          "values": ["User logged in", {"user_id": 42, "name": "John"}]
        },
        "origin": {
          "file": "/app/AuthController.php",
          "line_number": 55,
          "hostname": "dev-server"
        }
      },
      {
        "type": "color",
        "content": { "color": "green" },
        "origin": { "file": "/app/AuthController.php", "line_number": 55, "hostname": "dev-server" }
      },
      {
        "type": "label",
        "content": { "label": "Auth" },
        "origin": { "file": "/app/AuthController.php", "line_number": 55, "hostname": "dev-server" }
      }
    ],
    "meta": {
      "project_name": "my-app"
    }
  }'

Availability Check

Before sending data, you can check if Ray is running:

GET http://localhost:23517/_availability_check

Ray responds with HTTP 404 when available (the endpoint doesn't exist, but the server is running).

Getting Ray Information

Get Windows

Retrieve information about all open Ray windows:

GET http://localhost:23517/windows

Returns an array of window objects with their IDs and names:

json

[
  {"id": 1, "name": "Window 1"},
  {"id": 2, "name": "Debug Session"}
]

Get Theme Colors

Retrieve the current theme colors being used by Ray:

GET http://localhost:23517/theme

Returns the theme information including color palette:

json

{
  "name": "Dark",
  "colors": {
    "primary": "#000000",
    "secondary": "#1a1a1a",
    "accent": "#3b82f6"
  }
}

Use Case: When sending custom HTML content to Ray, use these theme colors to ensure your content matches Ray's current theme and looks visually integrated.

Example: Send HTML with matching colors:

bash

# First, get the theme
THEME=$(curl -s http://localhost:23517/theme)
PRIMARY_COLOR=$(echo $THEME | jq -r '.colors.primary')
 
# Then send HTML using those colors
curl -X POST http://localhost:23517/ \
  -H "Content-Type: application/json" \
  -d '{
    "uuid": "theme-matched-html",
    "payloads": [{
      "type": "custom",
      "content": {
        "content": "<div style=\"background: '"$PRIMARY_COLOR"'; padding: 20px;\"><h1>Themed Content</h1></div>",
        "label": "Themed HTML"
      },
      "origin": {"file": "script.sh", "line_number": 1, "hostname": "localhost"}
    }]
  }'
