Girdle: A JavaScript Utility Belt

Common errors

• TypeError: girdle.someFunction is not a function

  cause The imported `girdle` object does not contain a property named `someFunction`, or it's not a callable function. This could be due to incorrect function name, or the module structure being different than assumed.
  fix Verify the exact function name and its availability by inspecting the `girdle.js` source file directly. If using CommonJS, `console.log(Object.keys(girdle));` can help reveal available exports.

• Cannot find module 'girdle'

  cause The `girdle` package is not installed, or the module resolver cannot locate it. This often happens with incorrect `npm install` or environment issues.
  fix Ensure the package is correctly installed with `npm install girdle`. If running Node.js, confirm `node_modules` is in the expected path. If using a bundler, check its configuration.

• SyntaxError: Named export 'someUtilityFunction' not found. The requested module 'girdle' does not provide an export named 'someUtilityFunction'

  cause Attempting to use ESM named imports (`import { someUtilityFunction } from 'girdle';`) on a CommonJS-only module.
  fix Revert to CommonJS `require` syntax: `const { someUtilityFunction } = require('girdle');` or `const girdle = require('girdle'); const someUtilityFunction = girdle.someUtilityFunction;`. If using a bundler, ensure it's configured to correctly handle CJS interoperability for ESM imports.

Warnings

• breaking The library is pre-1.0 (version 0.3.8) and has been unmaintained for eight years. API stability is not guaranteed, and breaking changes could occur even between minor versions if the author were to update it. Use with caution in production environments.
  Fix: Thoroughly review the source code for specific utility signatures and test extensively before integrating into critical applications. Consider migrating to a more actively maintained library.
• gotcha This package is likely CommonJS-first due to its age. Direct `import` statements (ESM) may not work as expected in Node.js without explicit configuration or a bundler, leading to module resolution errors.
  Fix: Prefer `const girdle = require('girdle');` for Node.js environments. If using in a modern browser context with a bundler (e.g., Webpack, Rollup), `import * as girdle from 'girdle';` might be transpiled correctly.
• gotcha There are no official TypeScript declaration files (`.d.ts`) included with the package. This means TypeScript users will not get type safety, autocompletion, or compile-time checks for `girdle`'s utilities.
  Fix: Manually create declaration files (e.g., `girdle.d.ts`) or install community-contributed types if available (`@types/girdle`). If not, use `any` to bypass type checking, acknowledging the loss of type safety.
• gotcha The library is largely abandoned, with no updates in eight years. This implies a lack of security patches, bug fixes, or performance improvements, which could pose risks in evolving environments.
  Fix: Evaluate whether the specific functionalities needed are easily replaceable by native JavaScript features or more current, actively maintained utility libraries (e.g., Lodash, Ramda) to ensure long-term stability and security.

Install

• npm install girdle npm
• yarn add girdle yarn
• pnpm add girdle pnpm

Imports

• girdle
  wrong:

  import girdle from 'girdle';

  correct:

  const girdle = require('girdle');

  For Node.js environments, CommonJS `require` is the intended and most reliable way to import the library due to its age and likely CommonJS-first design. ESM `import` might only work via bundlers or specific Node.js configurations for CJS interoperability.
• someUtilityFunction
  wrong:

  import { someUtilityFunction } from 'girdle';

  correct:

  const { someUtilityFunction } = require('girdle');

  Assuming the library exports individual utilities as properties of its main export, this CommonJS destructuring is the correct approach. Direct ESM named imports are unlikely to work without transpilation/bundling due to the library's age.
• girdle

  import * as girdle from 'girdle';

  While primarily CommonJS, modern bundlers can often consume CJS modules and expose them as ESM namespaces. This approach allows access to all exported utilities as properties of the `girdle` object in ESM contexts.

Quickstart

Demonstrates how to install and use hypothetical utility functions from the `girdle` library in a CommonJS Node.js environment.

const girdle = require('girdle');

// Assuming 'girdle' exports a function called 'isString' and 'trim'
// (function names are illustrative as specific functions are not detailed in README)

if (girdle && typeof girdle === 'object' && typeof girdle.isString === 'function') {
  console.log('girdle.isString("hello"):', girdle.isString("hello"));
  console.log('girdle.isString(123):', girdle.isString(123));
} else {
  console.warn('girdle or girdle.isString not found, assuming an empty or different API structure.');
}

// Example of another hypothetical utility
if (girdle && typeof girdle === 'object' && typeof girdle.trim === 'function') {
  console.log('girdle.trim("  test  "):', girdle.trim("  test  "));
} else {
  console.warn('girdle or girdle.trim not found.');
}
