CookieOptions
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie
export interface CookieOptions
Property | Modifiers | Type | Description |
---|---|---|---|
domain? | string | (Optional) Defines the host to which the cookie will be sent. If omitted, this attribute defaults to the host of the current document URL, not including subdomains. | |
expires? | Date | string | (Optional) Indicates the maximum lifetime of the cookie as an HTTP-date timestamp. If both expires and maxAge are set, maxAge has precedence. | |
httpOnly? | boolean | (Optional) Forbids JavaScript from accessing the cookie, for example, through the document.cookie property. | |
maxAge? | number | [number, 'seconds' | 'minutes' | 'hours' | 'days' | 'weeks'] | (Optional) Indicates the number of seconds until the cookie expires. A zero or negative number will expire the cookie immediately. If both expires and maxAge are set, maxAge has precedence. You can also use the array syntax to set the max-age using minutes, hours, days or weeks. For example, { maxAge: [3, "days"] } would set the cookie to expire in 3 days. | |
path? | string | (Optional) Indicates the path that must exist in the requested URL for the browser to send the Cookie header. | |
sameSite? | 'strict' | 'lax' | 'none' | boolean | (Optional) Controls whether or not a cookie is sent with cross-site requests, providing some protection against cross-site request forgery attacks (CSRF). | |
secure? | boolean | (Optional) Indicates that the cookie is sent to the server only when a request is made with the https: scheme (except on localhost) |

exit | readonly | () => AbortMessage | |
html | readonly | (statusCode: StatusCodes, html: string) => AbortMessage | Convenience method to send an HTML body response. The response will be automatically set the Content-Type header totext/html; charset=utf-8. An html() response can only be called once. |
json | readonly | (statusCode: StatusCodes, data: any) => AbortMessage | Convenience method to JSON stringify the data and send it in the response. The response will be automatically set the Content-Type header to application/json; charset=utf-8. A json() response can only be called once. |
