Grammarly SDK Patterns

Overview

Production patterns for Grammarly API: typed client, token management, text chunking for large documents, and Python integration.

Instructions

Step 1: Typed API Client

class GrammarlyClient {
  private token: string;
  private expiresAt: number = 0;
  private base = 'https://api.grammarly.com/ecosystem/api';

  constructor(private clientId: string, private clientSecret: string) {}

  private async ensureToken() {
    if (Date.now() < this.expiresAt - 60000) return;
    const res = await fetch(`${this.base}/v1/oauth/token`, {
      method: 'POST',
      headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
      body: new URLSearchParams({ grant_type: 'client_credentials', client_id: this., : . }),
    });
     { access_token, expires_in } =  res.();
    . = access_token;
    . = .() + expires_in * ;
  }

   () {
     .();
     res =  (, {
      : ,
      : { : , :  },
      : .({ text }),
    });
     res.();
  }

   () {
     .();
     res =  (, {
      : ,
      : { : , :  },
      : .({ text }),
    });
     res.();
  }
}
