Next.js on Cloudflare Pages のエラー監視として Baselime を試す

npm i -S @baselime/edge-logger

type Params = {

  private createLogger(namespace: string): BaselimeLogger {

      ctx: { waitUntil: () => {}, passThroughOnException: () => {} },
      requestId: uuidv4(),
      isLocalDev: this.isLocalDev,
    });
  }

  private async log(
    level: "info" | "warn" | "error",
    { namespace, message }: Params,
  ) {
    const logger = this.createLogger(namespace);
    logger[level](message);
    await logger.flush();
  }

  }

  public error(params: Params) {

  }

  public warn(params: Params) {
    return this.log("warn", params);
  }
}

export const logger = new Logger();

await logger.error(`This is test error message`);
