Example app

To show how easy fetch(bible) is to use, here's a basic bible app created with a single file of plain HTML/CSS/JS. For a more complex example with a nicer UI you can also check out the web app and its source code.

// NOW FOR THE APP...
// Normally this would be even simpler when using a JS framework
// but we'll use plain JS for sake of demonstration


// Import the fetch(bible) client
// Normally you would import from '@gracious.tech/fetch-client' rather than a static file
import {BibleClient} from './client.mjs'


// Locate UI elements
const select_language = self.document.querySelector('.language')
const select_translation = self.document.querySelector('.translation')

const client = new BibleClient()
const collection = await client.fetch_collection()

        select_translation.value,
        select_book.value,
    )

}



// Method for populating the language <select> element

    update_options(select_language, languages.map(language => {
        return [

    update_options(select_chapter, chapters.map(c => [c, c]))
}



// Do initial update of dynamic UI elements

// Util for updating the options of a <select> element

    element.innerHTML = ''  // Remove existing options
    for (const item of items){
