Defaults from applyDefaults are merged into your chat.config.ts and the result is printed as JSON. 
npx @chat-js/cli@latest config [options]

How it works

The command spawns a short-lived process using your package manager inside your project directory that:
  1. Imports your chat.config.ts
  2. Passes it through applyDefaults from @/lib/config-schema
  3. Prints the result as formatted JSON to stdout
This means the output always reflects the effective configuration your app will use at runtime, including any defaults that are not explicitly set in chat.config.ts.

​
Example

npx @chat-js/cli@latest config

{
  "appName": "My Chat App",
  "gateway": {
    "provider": "vercel",
    "model": "gpt-4o"
  },
  "features": {
    "webSearch": false,
    "imageGeneration": false
  },
  "auth": {
    "providers": ["github"]
  }
}
Run from a different directory: 
npx @chat-js/cli@latest config --cwd ./apps/chat
