Scripting Helpers

URL Params

Access URL query parameters via the '&' module. If your query parameter is separated by dashes, such as this-that, then import it with camel case instead: thisThat.

/* import all at a prefix */

import * as Params from '&';

/* or, individual parameters */

import {specific, param, here as Other} from '&';

Form Params

Access form parameters via the 'form' module, or the 'form{}' module. If your form parameter is separated by dashes, such as this-that, then import it with camel case instead: thisThat.

/* individual parameters */

import {specific, param, here as Other} from 'form';

/* import as hash or object literal */

import {Form} from 'form{}';

let theValue = Form.theParamName;
let theOtherValue = Form['theOtherParam'];
let hasAValue = Form.has('checkboxValue');



Reading cookies may be done from any request or supplier. Keep in mind that cookie values may be null (may not exist).

import {token} from '🍪';

if (token){
} else {


Writing cookies may be done from non-GET requests, but not from suppliers. There is no functional difference between an implicit or explicit submit. Submitted cookies will only be included in the response if the script evaluates without exception.

import {Cookie} from '🍪';

// Implicit submit
new Cookie().name('token').value('123').days(30);

// Explicit submit'token').value('123').days(30).submit();

/* ... */
  • name(string) — Lower or camel case, and must not begin with "_" or equal "sid".
  • value(string) — Sets the value of the cookie.
  • days(number) — Creates a persistent cookie that expires.
  • invalidate() — Sets an empty value, and an expires in the past.

For security purposes cookies use the Secure, HttpOnly, SameSite=lax flags.


The Redirect object is already imported. The following examples show the available methods and their result.

Redirect.home(); // Result: /
Redirect.dir('accounts').dir(accountId); // Result: /accounts/1234/
Redirect.dir('accounts').dir(accountId).name('settings'); // Result: /accounts/1234/settings
Redirect.home().name('place').params({this:'that'});  // Result: /place?this=that
Redirect.index().name('other'); // If current request is /here/there, result: /here/other
Redirect.home().hash('123'); // Result /#123
Redirect.home().url.href; // Full URL including host

Redirects may also be used as JSON values:

({redirect: Redirect.home().success('Going Home')});

Resulting in:

{"redirect": {"path":"/", "messages":[{"type":"success", "value": "Going Home"}]}


As convenience to using the Messages object directly, messages may "go with" the redirect being built. For example, after adding a new Article:

import {Article} from '📦';

let article = new Article().title('New');

        .success('New Article successfully created');


The utilities module is named 'util' and exports the following objects and methods. All utilities are safe and efficient to use during any HTTP method.


Generates a URL and HTML friendly globally unique ID.

import {ID} from 'util';

let randomUnique = ID.generate();


import {Encoding} from 'util';



Identicons are a visual representation of any string value. Stacklane provides a utility to generate SVG identicons. These generated values may be stored in the SVG icon model field type.

import {Identicon} from 'util';

let repeatableIcon = Identicon.of('any string value');

let randomIcon = Identicon.random();


Utility for displaying relative date/times server-side, rather than resorting to a client-side library. Relative date/times are designed to give a general sense of time, not precision.

import {Post} from '📦';
import {RelativeDateTime} from 'util';

    createdAgo: RelativeDateTime.fromNow(p.created),
    title: p.title

Examples of RelativeDateTime.fromNow output:

3 seconds ago
6 hours ago
1 day ago
2 weeks ago
4 months ago
1.4 years ago

Only the year resolution will use a single decimal fraction.
