Battle.net

OAuth 2.0 provider for Battle.net.

Also see the OAuth 2.0 guide.

Initialization

import * as arctic from "arctic";

const battlenet = new arctic.BattleNet(clientId, clientSecret, redirectURI);

Create authorization URL

import * as arctic from "arctic";

const state = arctic.generateState();
const scopes = ["openid", "wow.profile"];
const url = battlenet.createAuthorizationURL(state, scopes);

Validate authorization code

validateAuthorizationCode() will either return an OAuth2Tokens, or throw one of OAuth2RequestError, ArcticFetchError, UnexpectedResponseError, or UnexpectedErrorResponseBodyError. Battle.net returns an access token and the access token expiration.

import * as arctic from "arctic";

try {
	const tokens = await battlenet.validateAuthorizationCode(code);
	const accessToken = tokens.accessToken();
} catch (e) {
	if (e instanceof arctic.OAuth2RequestError) {
		// Invalid authorization code, credentials, or redirect URI
		const code = e.code;
		// ...
	}
	if (e instanceof arctic.ArcticFetchError) {
		// Failed to call `fetch()`
		const cause = e.cause;
		// ...
	}
	// Parse error
}

Get user profile

Use the User Info endpoint.

const response = await fetch("https://oauth.battle.net/userinfo", {
	headers: {
		Authorization: `Bearer ${accessToken}`
	}
});
const user = await response.json();
