OAuth 2.0 provider for 42 School.

Also see the OAuth 2.0 guide.

Initialization

FortyTwo takes a client ID, client secret, and redirect URI.

import { FortyTwo } from "arctic";

const fortyTwo = new FortyTwo(clientId, clientSecret, redirectURI);

Create authorization URL

import { generateState } from "arctic";

const state = generateState();
const scopes = ["public", "projects"];
const url = fortyTwo.createAuthorizationURL(state, scopes);

Validate authorization code

import { OAuth2RequestError, ArcticFetchError } from "arctic";

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

You can retrieve user information via the /v2/me endpoint.

const response = await fetch("https://api.intra.42.fr/v2/me", {
	headers: {
		Authorization: `Bearer ${accessToken}`
	}
});
const user = await response.json();
