General Configuration

There are two types of configs: general configuration and widget configuration. The general configuration is the same for all widgets on one page. It is passed as the first parameter to WorkshopButlerWidgets.launch function

const sidebar = 
     type: 'SidebarEventList',
     hideIfEmpty: true,
     target: '#upcoming-events-nearby',
     eventPageUrl: '/event-page.html',
     length: 5,
     country: 'detect'

const widgetOptions = [sidebar];
const generalOptions = {
  apiKey: apiKey,
  locale: 'en-us'

WorkshopButlerWidgets.launch(generalOptions, widgetOptions);

Locale determines what language to use for rendering content and how numbers, dates and prices must be formatted.

The first part of the locale defines what language to use for content. Right now there are six languages supported by JS widgets: English (en), German (de), Portuguese (pt), Spanish (es), French (fr), and Dutch (nl). If you set a language, which is not supported, for example Russian (ru), English is used as a default one.


If you need to add a support for another language, add a new locale and create a PR:

The locale itself defines how numbers and dates are formatted. In the US (en-us), the formatting is different to Britain (en-gb). You can find the list of locales here. It is important to notice that we do not guarantee all locales from the list work correctly. Try it yourself!


Right now we use full locales (en-gb) only for formatting numbers, dates and prices. There is only one translation per language (en). For example, there is no difference between British and American English.

If you want to add a support for a particular version of language, add a new locale and create a PR:

User dictionary

As you already know, there are six supported languages. Sometimes you need to change a few phrases because the default ones do not suit your needs. The user dictionary allows you to do that.

How it works

All phrases and words that you see and which are not retrieved from Workshop Butler API, are represented by tokens. For example, the Location filter has a value All locations. The phrase All locations is stored in filter.locations token and its value is different from locale to locale. To replace its value to All countries, we'll need to set filter.locations in a user dictionary.

const generalOptions = {
  apiKey: apiKey,
  locale: 'en-us',
  dict: {
    en: {
      filter: {
        locations: "All countries"
WorkshopButlerWidgets.launch(generalOptions, ...);

As you can see, first you need to pass a locale for which you want to replace a token, and then a structure, identical to a default one.

How to find a token

To find a token, open the list of locales, select the one you need, and search for the phrase you want to replace. After that, use the token in a user dictionary.

To simplify the process, here's a short description of all high-level blocks from default locales:

  • filter contains the tokens, used in workshop and trainer filters
  • country contains the names of countries
  • language contains the names of languages
  • rating contains the values from By rating filter
  • schedule contains the tokens from Schedule widget
  • trainers contains the tokens from TrainerList widget
  • event contains the tokens from EventPage widget
  • trainer contains the tokens from TrainerProfile widget
  • tax contains the tokens about included/excluded VAT
  • form contains the tokens from RegistrationForm widget
  • registration contains the texts the user sees after completing a registration
  • sidebar contains the tokens related to SidebarEventList widget
