MTG decklist parser

Library for parsing MTG Online & Arena decklists

Installation

The library is available as a package on npm. Currently there is no static location for a production file to hotlink to.

npm install mtg-decklist-parser --save

After that import the Decklist class from the library. This is where all parsing is done. Just pass your decklist string into the constructor of the class.

import {Decklist} from 'mtg-decklist-parser';

let parsed = new Decklist(rawString);

If manually building the library to include in your project, the Decklist class will be available in the MTGParser global object.

let parsed = new MTGParser.Decklist(rawString);

API documentation

Decklists to be given to the parser follow the conventional newline separated format that can be found on many popular sites such as MTGGoldfish. Supports lists exported from MTG Arena and MTGO .dek files. There are multiple example decklists in the example folder.

Decklist & MTGO

Both the Decklist and MTGO classes share the same properties. Both expect strings passed into their constructor.

companion	CardModel	If a companion is specified in the input will be available, otherwise null.
commander	CardModel	If a commander is specified in the input will be available, otherwise null.
