D2s Save

d2s

The goal of this project is to create an es6 compliant reader/writer of Diablo II save files. Additionally, the library should be able to consume files generated by nokka's Go implementation d2s, therefore the output of reading a save will closely mirror the Go's output.

Examples

• Viewer [Source]
• Editor [Source]

Using d2s-ui for a frontend:

API/General Usage

/**
* @see constants.bundle.min.js for an already parsed version of 1.13c data
* @param buffers: object of ALL txt files. example: {
*  "ItemStatCost.txt": "Stat\tIDt\Send...",
*  "string.txt": "WarrivAct1IntroGossip1\t45}Greetings,...",
*  ...
* }
* @return constants: constant data required for parsing built from the txt files.
**/
function readConstantData(buffers: any): types.IConstantData

/**
* @param buffer: Uint8Array representation of the file
* @param constants: constant data used for reading the files. @see readConstantData or constants.bundle.min.js
* @param userConfig: optional configuration. used for if there is a dll edit to allow larger stash sizes. example: {
*  extendedStash: true
* }
* @return d2s: the parsed save information
**/
function read(buffer: Uint8Array, constants: types.IConstantData, userConfig?: types.IConfig): Promise<types.ID2S>;
