Parser module of Genshin Toolkit
This module serves as a core component of all tools built in the Genshin Toolkit chain. This module depends on zod
for data validation and parsing.
Usage
The current version has support for extracting game data from a HAR file captured from your Battle Chronicle. You need to be signed-in to obtain your game data
If you aren't sure on how to capture the HAR, follow instructions from this Guide by Microsoft for the browser you intend to work on:
Importing modules
Use core imports for node and web
for web environments
// For node environment
import { DataProvider } from "@genshin-toolkit/parser";
// For web environments
import { DataProvider } from "@genshin-toolkit/parser/web";
Create a new DataProvider
instance.
There are data provider classes for specific use cases, for Node and for Web:
Cross-environment
BufferDataProvider
If you have the HARBuffer
at hand, you can use thisDataProvider
instead.StringDataProvider
Reads data from rawString
.
Node only
FileDataProvider
This is the provider you'll be using if you want to skip the hassle of reading the file yourself and passing in the buffer to theDataProvider
.
Web only
WebFileDataProvider
AlternateDataProvider
forFileDataProvider
to be used in browsers.import { BufferDataProvider, FileDataProvider, loadFromHar, } from "@genshin-toolkit/parser"; const fileDataProvider = new FileDataProvider("..path-to.har"); // or const bufferDataProvider = new BufferDataProvider(buffer); // or const stringDataProvider = new StringDataProvider("{...string_data...}");
Call
loadFromHar
to extract and parse game data from a HAR file.const gameData = await loadFromHar(provider); // Tabular display (example) console.table(gameData.avatars.map(avatar => ({ character: avatar.name, level: avatar.level, weapon: `${avatar.weapon?.type_name}/${avatar.weapon?.name} - lv${avatar.weapon?.level}`, friendship: `lv${avatar.fetter}` })));
Examples
Below are the examples of loading data from HAR for two different use-cases (Use async
function wrapper if using await
):
Parsing data from a local file
import { FileDataProvider, loadFromHar } from "@genshin-toolkit/parser";
const provider = new FileDataProvider("/home/path/to.har");
const gameDataFactory = await loadFromHar(provider);
Parsing game data from a game data file
If you want to parse the game data (data parsed from HAR with loadFromHar
and saved on disk or a GameData
schema compatible json file)
import { FileDataProvider, loadFromFile } from "@genshin-toolkit/parser";
const provider = new FileDataProvider("/home/path/gamedata.json");
const gameDataFactory = await loadFromFile(provider);
Parsing on the web
Use WebFileDataProvider
to directly work with the File
provided by the provided by the browser on picking a file. Or use cross-env DataProviders
like BufferDataProvider
if you already have the file Buffer
in memory.
If using TypeScript, your module resolution should be the newer
Node16
orNodeNext
when trying to importparser/web
.
import { WebFileDataProvider } from '@genshin-toolkit/parser/web';
document.getElementById('fileInput').addEventListener('change', async (event) => {
const input = event.target as HTMLInputElement;
if (input.files && input.files.length > 0) {
const file = input.files[0];
const provider = new WebFileDataProvider(file);
try {
const data = await provider.load();
// Parse with loadFromHar or loadFromFile here.
console.log('File data loaded:', data);
} catch (error) {
console.error('Error loading file:', error);
}
}
});
