pack-format

pack-format is a tool for retrieving the pack_format of any Minecraft version, including snapshots.

About

pack_format is a version number used by Minecraft in both resource packs and data packs for labeling compatible versions. It was added in Minecraft version 1.6, and as such using this tool on any version prior to that will just return undefined.

Install

pack-format is available on npm. You must have Node.js installed to be able to use this.

To install pack-format, open the command line and type npm install pack-format to use for a Node.js project, or npm install -g pack-format to use from the command line.

Usage

Node

Retrieve the pack_format of a given Minecraft version, optionally specifying whether the resource (default) or data pack version should be returned.

const packFormat = require('pack-format')
packFormat('1.14.4') // 4
packFormat('1.16.2-pre1', 'resource') // 5
packFormat('20w45a', 'data') // 6
packFormat.LATEST.data // 39

Retrieve a list of versions corresponding to a specific pack_format, again optionally specifying resource/data pack version.

const {getVersions} = require('pack-format')
getVersions(3) // { releases: { min: '1.11.x', max: '1.12.x' }, snapshots: { min: '16w32a', max: '17w47a' } }
getVersions(6, 'data') // { releases: { min: '1.15.x', max: '1.16.1' }, snapshots: { min: '20w06a', max: '20w44a' } }

Command line

Retrieve both the resource and data pack_format of a given Minecraft version:

pack-format [--data|--resource] <version>

Retrieve a list of corresponding Minecraft versions:

pack-format --list [--data|--resource] <pack_format>

Examples:

> pack-format 1.14.4
Resource pack format of 1.14.4 is 4
Data pack format of 1.14.4 is 4

> pack-format --resource 1.16.2-pre1
Resource pack format of 1.16.2-pre1 is 5

> pack-format --data 20w45a

> pack-format --list --resource 3
{ releases: { min: '1.11.x', max: '1.12.x' }, snapshots: { min: '16w32a', max: '17w47a' } }
