DEPRECATED! Replacement: @csedl/stimulus-initializer

On Rails we are familiar with nice and handy conventions that saving a lot of time.

At this tutorial i showed a way for integrating Svelte and Stimulus for handy tools for simplifying our javascript process.

On the Handbook Stimulus has shown a default way for declaring keys based of the controller filenames. While this is a safe way i found this double-dashes silly and the namespaces could be shortened. Of course, if you want to have a naming where you can be 100% there is never a conflict, please stay at this default way. That is what this module, by default, does.

For a smarter naming this module adds some options.

This module corresponds with vite-svelte-initializer.

If, a conflict occours, it alerts on console with a log entry and on Browser with a alert.

Assume a file structure like so:

frontend/javascript/

- components
   |-- articles
      |-- select-controller.js
- global
   |-- select-controller.js

default: the safe way

frontend/entrypoints/application.js

import { initStimulus } from "vite-stimulus-initializer";

const comps = import.meta.glob('../javascript/components/**/*-controller.js', { eager: true })
initStimulus(comps, 2)

=> "2", the second parameter tells that the first two parts of the part (".." and "javascript" are excluded from namespacing, so it generates the tagname:

components--articles--select, which can be applied as custom element in the view by <div data-controller="components--articles--select" > .. </div>, and a global--select tag.

optional: the smarter way

for making this more handy, you can:

frontend/entrypoints/application.js

import { initStimulus } from "vite-stimulus-initializer";

const apps = import.meta.glob('../javascript/components/**/*-controller.js', { eager: true })
initStimulus(apps, 2, { debug: true, exclude: ['components'], folderSeparator: '-' })

this prints out on console (because of debug: true):

• STIMULUS IDENTIFIER «articles-select» from: ./components/views/admin/sub/next-controller.js
• STIMULUS IDENTIFIER «global-select» from: ./global/select-controller.js

and having no more double-dash because of folderSeparator: '-'

The exclude: [..] is only applied for the level-3, which means: the first two levels are excluded completely because of second parameter, and the next is targeted by exclude.

and generates the corresponding tags.

Hope you enjoy!
