Grammarly Deploy Integration

Overview

Deploy a containerized Grammarly writing assistant integration service with Docker. This skill covers building a production image that connects to the Grammarly Text API for checking grammar, clarity, and tone across submitted text. Includes environment configuration for OAuth client credentials, health checks that verify API token exchange and text analysis endpoints, and rolling update strategies for zero-downtime deployments serving real-time writing feedback.

        : process..!,
      }),
    });
     (!tokenRes.)   ();
    res.({ : , : , :  ().() });
  }  (error) {
    res.().({ : , : (error  ). });
  }
