@typeship/exception

An exception class implementation that inherits Error. Useful for TypeScript projects that need to check that an object is an error. See: the X instanceof BuiltinConstructor expression to return false.

Usage

import { Exception } from "@typeship/exception";

class MyException extends Exception {}

import { Exception } from "@typeship/exception";

if (process.env["NODE_ENV"] !== "production") {
  throw new Exception("This file should not be imported in production");
}

import { Exception } from "@typeship/exception";

try {
  fn();
} catch (e) {
  if (e instanceof Exception) {
    // do something
  }
}
