Keycloak authorization library for NestJS. Works out of the box.

import { Logger } from "@nestjs/common";
import { KeycloakAuth } from "../constant/keycloak.auth.js";
export class KeycloakConfig {
    realm;
    authServerUrl;
    pubKey;
    constructor(realm, authServerUrl) {
        this.realm = realm;
        this.authServerUrl = authServerUrl;
    }
    getRealm() {
        return this.realm;
    }
    getAuthServerUrl() {
        return this.authServerUrl;
    }
    async publicKey() {
        if (this.pubKey) {
            return this.pubKey;
        }
        const CERT_HEADER = "-----BEGIN PUBLIC KEY-----\n";
        const CERT_FOOTER = "\n-----END PUBLIC KEY-----";
        try {
            const response = await fetch(`${this.authServerUrl}/realms/${this.realm}`);
            const data = await response.json();
            Logger.debug("Obtained public key for jwt token verification.", KeycloakAuth.NAME);
            this.pubKey = `${CERT_HEADER}${data["public_key"]}${CERT_FOOTER}`;
            return this.pubKey;
        }
        catch (err) {
            Logger.error(`Could not obtain public key for jwt token verification: ${err.message}`, KeycloakAuth.NAME);
            throw new Error("Could not obtain public key for jwt token verification!");
        }
    }
}
