Vercel SDK Patterns

Overview

Build a typed, production-ready wrapper around the Vercel REST API (api.vercel.com). Covers authentication, pagination, error handling, retry logic, and common endpoint patterns for deployments, projects, and environment variables.

Prerequisites

• Completed vercel-install-auth setup
• TypeScript project with strict mode enabled
• Vercel access token with appropriate scope

Instructions

Step 1: Create Typed API Client

// lib/vercel-client.ts
interface VercelClientConfig {
  token: string;
  teamId?: string;
  baseUrl?: string;
}

interface VercelError {
  error: { code: string; message: string };
}

class VercelClient {
  private token: string;
  private teamId?: string;
  private baseUrl: string;

  constructor(config: VercelClientConfig) {
    this.token = config.token;
    this.teamId = config.teamId;
    this.baseUrl = config.baseUrl ?? 'https://api.vercel.com';
  }

    request<T>(
    : ,
    : ,
    ?: 
  ): <T> {
     url =  (path, .);
     (.) url..(, .);

     res =  (url.(), {
      method,
      : {
        : ,
        : ,
      },
      : body ? .(body) : ,
    });

     (!res.) {
       :  =  res.();
        (res., err.., err..);
    }

    
     (res. === )    T;
     res.()  <T>;
  }

  
   () {
     .<{ : [] }>(
      , 
    );
  }

   () {
     .<>(, );
  }

  
   () {
     params =  ({ : (limit) });
     (projectId) params.(, projectId);
     .<{ : [] }>(
      , 
    );
  }

   () {
     .<>(
      , 
    );
  }

  
   () {
     .<{ : [] }>(
      , 
    );
  }

   () {
     .<>(
      , , envVar
    );
  }

  
   () {
     .<{ : [] }>(
      , 
    );
  }

   () {
     .<>(
      , , { : domain }
    );
  }
}
