Given a bible reference, validates it and returns an object with book, chapter, verse and more
Throw a bible reference at chapter-and-verse and, if valid, it returns a detailed JSON object for that reference.
If invalid, it returns a JSON object with the reason for failure.
chapter-and-verse understands all common bible book abbreviations and has its own built-in book identification algorithm.
It is useful when building biblical reference based URLs, for integrating with bible APIs and for validating raw user input.
chapter-and-verse is written by a professional developer, has 100% unit test coverage and is ready for production use.
All our biblical data has been triple checked to ensure reliability.
chapter-and-verse works in Node code and browsers.
chapter-and-verse supports all the following reference formats:
| format | example | notes |
|--------------------- |--------------- |--------------------------- |
| book | Genesis | |
| book chapter | Genesis 5 | multi chapter books |
| book verse | Obadiah 3 | single chapter books |
| book verses | Obadiah 3-5 | single chapter books only |
| book chapter:verse | Genesis 5:1 | |
| book chapter:verses | Genesis 5:1-4 | |
npm install --save chapter-and-verse
Usage:
``javascript 1.7`
const chapterAndVerse = require('chapter-and-verse')
let cv = chapterAndVerse('Dan 4:1-3')
And cv now looks like:
`json`
{
"book": {
"id": "Dan",
"name": "Daniel",
"testament": "O",
"start": "dan",
"abbr": ["da", "dn"],
"chapters": 12,
"versesPerChapter": [21, 49, 30, 37, 31, 28, 28, 27, 27, 21, 45, 13]
},
"success": true,
"reason": "matches book.id",
"chapter": 4,
"from": 1,
"to": 3
}
To validate a reference:
`javascript 1.7`
const chapterAndVerse = require('chapter-and-verse')
const ref = 'Dan 4:1-3'
let cv = chapterAndVerse(ref)
if (cv.success === true) {
console.log(ref + ' is valid')
}
if (cv.success === false) {
console.log(ref + ' is invalid because ' + cv.reason)
}
For more information see the Validation section.
npm install --save chapter-and-verse
Add a script tag in head:
`HTML`
Then use as follows:
`HTML`
You can validate a reference as described in the Usage section.
For a valid reference a number of methods are available.
Use cv.toString() and cv.toShortString() as follows:
`javascript 1.7
cv = chapterAndVerse('Dan 4:1-3')
cv.toString() // returns 'Daniel 4:1-3'
cv.toShortString() // returns 'Daniel 4:1-3' .. no difference because Daniel is a multi chapter book
cv = chapterAndVerse('ob 1-3')
cv.toString() // returns 'Obadiah 1:1-3'
cv.toShortString() // returns 'Obadiah 1-3' .. difference because Obadiah is a single chapter book
`
cv.getType() returns one of 'book', 'chapter', 'verses' or 'verse'
Finally cv.toSimpleObject() provides access to a flat object containing only essential data:
`javascript 1.7`
cv = chapterAndVerse('exo 33:7-12')
cv.toSimpleObject()
Which returns:
`json`
{
"type": "verses",
"asString": "Exodus 33:7-12",
"asShortString": "Exodus 33:7-12",
"bookId": "Exod",
"bookName": "Exodus",
"testament": "O",
"chapter": 33,
"from": 7,
"to": 12
}
chapter-and-verse returns a failure object if it cannot resolve the biblical reference:
`json`
{
"book": {},
"success": false,
"reason": "book does not exist"
}
This happens when the:
* Book does not exist / cannot be identified
* Chapter does not exist
* Verse does not exist - see Translation specifics
* "book verses" reference format - see Supported reference formats - is used in conjunction with a multi chapter book
* reference format is unrecognised - see Supported reference formats
* reference is not a string
chapter-and-verse does NOT recognise apocryphal books.
All our chapter and verse data has been "triple checked" as follows:
(1) The data was entered manually and manually checked.
(2) We then ran code against our data, ensuring verse and chapter totals were correct.
(3) Finally, we programmatically tested our data against other online sources to ensure "total agreement".
Certain verses only exist in certain translations.
* 3 John 15
chapter-and-verse reports 3 John 15 as valid. However, this verse does not exist in the KJV wherein it has been merged with 3 John 14.
This is the only chapter-and-verse discrepancy with the KJV.
Compare 3 John 14-15 ESV with 3 John 14 KJV
* Omitted verses
In modern English translations, certain New Testament verses, which exist in the KJV, have been omitted.
For example Matthew 17:21 ESV does not exist whereas Matthew 17:21 KJV does exist.
chapter-and-verse` treats all omitted verses as valid and is not concerned with translation specifics.

The Lord bless you and keep you;
the Lord make his face to shine upon you and be gracious to you;
the Lord lift up his countenance upon you and give you peace.
