Backend Kit

A small collection of reusable backend utilities for Node.js and Express.

I built this to avoid rewriting the same boilerplate code (like error handling and API responses) in every project.

Installation

npm install @tastypotato1708/backend-kit

What's inside

ApiError

A simple custom error class to standardize error handling.

import { ApiError } from "@tastypotato1708/backend-kit";

throw new ApiError(400, "Invalid request");

ApiResponse

A clean way to send consistent API responses.

import { ApiResponse } from "@tastypotato1708/backend-kit";

res.status(200).json(new ApiResponse(200, data, "Fetched successfully"));

asyncHandler

import { asyncHandler, ApiResponse } from "@tastypotato1708/backend-kit";
import { ApiResponse } from "@tastypotato1708/backend-kit";

const getData = asyncHandler(async (req, res) => {
  const data = await someAsyncFunction();

  res
    .status(200)
    .json(new ApiResponse(200, data, "Fetched successfully"));
});

export { getData };

Why I made this

In most backend projects, I kept writing the same patterns again and again:

• custom error classes
• consistent API response format
• basic utilities

So I decided to bundle them into a small reusable package.

Note

I made this mainly for my own projects, just to reuse common backend code.
