const { cookies: mergedCookies } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome", "firefox", "safari"],
  mode: "merge",
});

// mode: "first" - Return cookies from the first browser that yields results
const { cookies: firstCookies } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome", "firefox", "safari"],
  mode: "first", // Stops after Chrome if Chrome has cookies
});

// Useful when you only need cookies from one browser and want to fail fast
const { cookies, warnings } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome"],
  mode: "first",
  timeoutMs: 5000, // Timeout for keychain/keyring access
});
```

### Convert Cookies to HTTP Header with TypeScript

Source: https://context7.com/steipete/sweet-cookie/llms.txt

Use toCookieHeader to format an array of cookies into a string for the Cookie header, with options for deduplication and sorting.

```typescript
import { getCookies, toCookieHeader } from "@steipete/sweet-cookie";

const { cookies } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome"],
});

// Basic usage - sorted by name
const header = toCookieHeader(cookies);
// Output: "csrf=xyz789; session=abc123"

// Deduplicate by name (keeps first occurrence)
const dedupedHeader = toCookieHeader(cookies, { dedupeByName: true });
// Output: "csrf=xyz789; session=abc123"

// Preserve original order (no sorting)
const unsortedHeader = toCookieHeader(cookies, { sort: "none" });
// Output: "session=abc123; csrf=xyz789" (original order)

// Combined options
const finalHeader = toCookieHeader(cookies, {
  dedupeByName: true,
  sort: "name",
});

// Use with fetch
const response = await fetch("https://api.example.com/data", {

### Target Chromium Browsers on macOS

Source: https://context7.com/steipete/sweet-cookie/llms.txt

Specify a chromiumBrowser to avoid multiple keychain prompts on macOS. Without this, the library may check multiple browser roots by default.

```typescript
import { getCookies } from "@steipete/sweet-cookie";

// Target Brave browser specifically on macOS
const { cookies: braveCookies } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome"],
  chromiumBrowser: "brave", // 'chrome' | 'brave' | 'arc' | 'chromium'
});

// Target Arc browser
const { cookies: arcCookies } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome"],
  chromiumBrowser: "arc",
});

// Without chromiumBrowser, macOS checks Chrome and Brave roots by default
const { cookies: defaultCookies } = await getCookies({
  url: "https://example.com/",
  browsers: ["chrome"],
  // Will try Chrome first, then Brave
});
```

--------------------------------

### Extract Cookies for Multiple Origins

Source: https://context7.com/steipete/sweet-cookie/llms.txt

Configure multi-origin extraction to support OAuth and SSO flows where authentication spans several domains.

```typescript
import { getCookies } from "@steipete/sweet-cookie";

// Multi-origin extraction for OAuth/SSO flows
const { cookies } = await getCookies({
  url: "https://app.example.com/",
  origins: [
    "https://accounts.example.com/",
    "https://login.example.com/",
    "https://auth.example.com/",
  ],
  names: ["session", "xsrf", "access_token"],
  browsers: ["chrome"],
  mode: "merge", // Combine cookies from all browsers (default)
});

// All cookies matching any of the specified origins are returned
console.log(`Found ${cookies.length} cookies across ${new Set(cookies.map(c => c.domain)).size} domains`);
```

--------------------------------

### Extract Cookies from Browsers

Source: https://context7.com/steipete/sweet-cookie/llms.txt

Use getCookies to retrieve specific cookies from local browser databases. The function returns both the cookie data and any non-fatal warnings encountered during extraction.

```typescript
import { getCookies } from "@steipete/sweet-cookie";

// Basic usage - extract specific cookies from local browsers
const { cookies, warnings } = await getCookies({
  url: "https://example.com/",
  names: ["session", "csrf"],
  browsers: ["chrome", "edge", "firefox", "safari"],
});

// Log any warnings (missing keyring tools, schema drift, etc.)
for (const warning of warnings) {
  console.warn(warning);
}

// Output: Array of Cookie objects
// [
//   {
//     name: "session",
//     value: "abc123...",
//     domain: "example.com",
//     path: "/",
//     expires: 1767225600,
//     secure: true,
//     httpOnly: true,
//     sameSite: "Lax",
//     source: { browser: "chrome", profile: "Default" }
//   },
//   { name: "csrf", value: "xyz789...", domain: "example.com", path: "/" }
// ]
```

### Define CDP-Compatible Cookie Objects

Source: https://context7.com/steipete/sweet-cookie/llms.txt

Utilize the Cookie interface for type-safe cookie handling, compatible with Chrome DevTools Protocol structures.

```typescript
import type { Cookie, BrowserName, CookieSameSite } from "@steipete/sweet-cookie";

// Full Cookie interface
const cookie: Cookie = {
  name: "session",           // Required: cookie name
  value: "abc123xyz",        // Required: cookie value (may be empty string)
  domain: "example.com",     // Optional: hostname without leading dot
  path: "/",                 // Optional: defaults to "/" when omitted
  url: "https://example.com", // Optional: useful for host-only cookies
  expires: 1767225600,       // Optional: Unix timestamp in seconds (omit for session)
  secure: true,              // Optional: HTTPS only
  httpOnly: true,            // Optional: not accessible to JavaScript
  sameSite: "Lax",           // Optional: "Strict" | "Lax" | "None"
  source: {                  // Optional: provenance metadata
    browser: "chrome",       // Which browser: "chrome" | "edge" | "firefox" | "safari"
    profile: "Default",      // Optional: profile identifier
    origin: "https://example.com", // Optional: origin that produced this cookie
    storeId: "0",            // Optional: cookie store identifier
  },
};

// Type definitions
type BrowserName = "chrome" | "edge" | "firefox" | "safari";
type CookieSameSite = "Strict" | "Lax" | "None";
```

--------------------------------

### Inject Inline Cookies

Source: https://context7.com/steipete/sweet-cookie/llms.txt

Provide cookies directly via JSON, base64 strings, or file paths to bypass browser database access. This is useful for reliability when using exports from the companion Chrome extension.

```typescript
import { getCookies } from "@steipete/sweet-cookie";

// From JSON string (Cookie[] or { cookies: Cookie[] } format)
const { cookies: jsonCookies } = await getCookies({
  url: "https://chatgpt.com/",
  inlineCookiesJson: JSON.stringify({
    cookies: [
      { name: "session", value: "abc123", domain: "chatgpt.com", path: "/" },
      { name: "csrf", value: "xyz789", domain: "chatgpt.com", path: "/" },
    ],
  }),
  browsers: ["chrome"], // Skipped when inline yields cookies
});

// From base64-encoded JSON (clipboard-friendly from extension)
const base64Payload = Buffer.from(JSON.stringify({
  cookies: [{ name: "session", value: "abc123", domain: "chatgpt.com", path: "/" }]
})).toString("base64");

const { cookies: base64Cookies } = await getCookies({
  url: "https://chatgpt.com/",
  inlineCookiesBase64: base64Payload,
});

// From file path (exported from extension)
const { cookies: fileCookies } = await getCookies({
  url: "https://chatgpt.com/",
  inlineCookiesFile: "/path/to/exported-cookies.json",
});
```

--------------------------------

### Inline Cookie Payload Schema

Source: https://context7.com/steipete/sweet-cookie/llms.txt

This JSON schema represents cookies exported from a Chrome MV3 extension. It includes metadata about the export and a list of cookies with their properties.

```json
{
  "version": 1,
  "generatedAt": "2025-12-27T18:00:00.000Z",
  "source": "sweet-cookie",
  "browser": "chrome",
  "targetUrl": "https://chatgpt.com/",
  "origins": ["https://chatgpt.com/"],
  "cookies": [
    {
      "name": "__Secure-next-auth.session-token",
      "value": "eyJhbGciOiJkaXIiLCJlbmMiOiJBMjU2R0NNIn0...",
      "domain": "chatgpt.com",
      "path": "/",
      "secure": true,
      "httpOnly": true,
      "sameSite": "Lax",
      "expires": 1767225600
    },
    {
      "name": "cf_clearance",
      "value": "abc123...",
      "domain": ".chatgpt.com",
      "path": "/",
      "secure": true,
      "httpOnly": true,
      "sameSite": "None",
      "expires": 1735660800
    }
  ]
}
```

--------------------------------

### JSON Cookie Export Structure

Source: https://github.com/steipete/sweet-cookie/blob/main/docs/spec.md

This JSON structure represents exported cookies, including metadata and an array of cookie objects. The 'expires' field should be in Unix seconds when available, and omitted for session cookies.

```json
{
	"version": 1,
	"generatedAt": "2025-12-27T18:00:00.000Z",
	"source": "sweet-cookie",
	"browser": "chrome",
	"targetUrl": "https://chatgpt.com/",
	"origins": ["https://chatgpt.com/"],
	"cookies": [
		{
			"name": "__Secure-next-auth.session-token",
			"value": "…",
			"domain": "chatgpt.com",
			"path": "/",
			"secure": true,
			"httpOnly": true,
			"sameSite": "Lax",
			"expires": 1767225600
		}
	]
}
```
