wick-downloader

An asynchronous partial EGS downloader. This can be used to download individual asset files without downloading the entire archive.

Note: This build requires that oo2core_8_win64.dll on Windows or oo2core_8_win64.so on Linux exists in the working directory.

API

WickDownloader

constructor()

const { WickDownloader } = require('wick-downloader');
const wickdl = new WickDownloader();

startService(): void

This function must be executed to initialize the state of the downloader. Internally, this involves setting up the HTTP service and fetching the App and Chunk manifests for the latest version.

await wickdl.startService();

getPakNames(): string[]

This returns a list of strings showing the relative path of each utoc and ucas file that can be accessed.

getUtoc(filename: string): Promise<UtocServiceContainer>

Used to initialize an individual utoc service. The filename argument must be an exact match to one of the entries returned from getPakNames, and must only be a utoc file.

const pakNames = wickdl.getPakNames();

// NOTE: The first item may not be the *.utoc file, a *.ucas won't be accepted
const utocService = await wickdl.getUtoc(pakNames[0]);

getFileData(pak: UtocServiceContainer, filename: string): Promise<Buffer>

Downloads an individual asset file specified in filename from the pak service, returning a Buffer with the contents.

const fileData = await wickdl.getFileData(pakService, pakService.get_file_names()[0]);

shutdown()

Clears up the internal runtime and callback procedures. This is necessary to finish execution of the script.
