Everlast Brands - Error Handling

Still Under Active Development

This package provides tools to send responses, create custom errors, and catch errors gracefully in Everlast Brands services.

All methods are compatible with ExpressJs only.

Functions

Async Wrapper: Wraps async endpoint methods

// In an express app
app.post("/user", asyncWrapper(createUser));

Send: Standardizes responses

// In a controller method in express
export async function createUser(req, res) {
  const result = await User.create(req.body);
  if (!result) {
    send({ res, message: "Failed to create user", status: 500 });
    return;
  }
  send({ res, data: { user: result }, message: "User Created" });
}

Classes

CustomeError: Extends the default error class and allows custom errors to be created. Utilizes an additional status property that reflects http status codes.

const FailedToCreateUserError = new CustomError(
  "CreateError",
  "Failed to create user",
  500
);
// Usage
throw FailedToCreateUserError;
