Easy Soft Utility Library

2.8.115 · active · verified Sun Apr 19

easy-soft-utility is a JavaScript/TypeScript utility library, currently at version 2.8.115, that appears to be part of a larger 'easy-soft' ecosystem based on its GitHub repository. While the provided documentation (README and npm description) is minimal, such libraries typically offer a collection of helper functions for common programming tasks across areas like data manipulation, type checking, string operations, or functional programming patterns. The exact scope and API surface are not clearly defined in public materials, suggesting a potentially internal-focused library or one with evolving external documentation. Given its version number, it indicates active development, but users should be aware of the limited public API details and potential for changes due to the lack of explicit changelogs or usage guides. The release cadence cannot be reliably determined from the available information.

Common errors

```
TypeError: easySoftUtility.someFunction is not a function
```
cause Attempting to call a non-existent function or accessing a function that is not exported or has a different name.

fix Verify the exact function name and its availability by inspecting the package's TypeScript declaration files (`.d.ts`) or source code. Ensure correct import syntax (named import vs. default import, CommonJS vs. ESM).
```
Cannot find module 'easy-soft-utility' or its corresponding type declarations.
```
cause The package is not installed, or TypeScript cannot locate its type definitions. This can also happen in a mixed CJS/ESM project if module resolution settings are incorrect.

fix Run `npm install easy-soft-utility` or `yarn add easy-soft-utility`. Ensure `tsconfig.json` `moduleResolution` is set appropriately (e.g., `"node16"` or `"bundler"`) for modern module resolution.
```
ReferenceError: require is not defined (when using 'require' in an ESM module)
```
cause Using CommonJS `require` syntax in a JavaScript file that is treated as an ES Module (e.g., `type: 'module'` in `package.json`, or `.mjs` file extension).

fix Refactor imports to use ES Module syntax: `import { someFunction } from 'easy-soft-utility';`. If an entire module object is needed, use `import * as easySoftUtility from 'easy-soft-utility';`.

Warnings

gotcha The official README is marked with 'TODO: description' and lacks a detailed API overview. This means the specific functionality and behavior of many utilities are not publicly documented, requiring experimentation or source code review.
Fix: Consult the source code if specific utility behavior is unclear, or use robust type checking in TypeScript to catch potential API mismatches.
breaking Due to the absence of a public changelog or clear API contract, breaking changes might occur between minor or even patch versions without explicit notification, requiring careful testing upon upgrades.
Fix: Pin exact versions (`"easy-soft-utility": "2.8.115"`) in `package.json` to prevent unexpected updates. Conduct thorough regression testing after any version bump.
gotcha The provided README uses `const easySoftUtility = require('easy-soft-utility');`, which is a CommonJS import. While the package ships TypeScript types, implying modern usage, relying solely on this CommonJS pattern in a modern ESM project might lead to bundling or tree-shaking inefficiencies.
Fix: Prefer ESM named imports (`import { functionName } from 'easy-soft-utility';`) in TypeScript and modern JavaScript projects to leverage tree-shaking and maintain consistency.

Install

npm install easy-soft-utility npm
yarn add easy-soft-utility yarn
pnpm add easy-soft-utility pnpm

Imports

isString
wrong:
```
const easySoftUtility = require('easy-soft-utility'); const isString = easySoftUtility.isString;
```
correct:
```
import { isString } from 'easy-soft-utility';
```
For modern TypeScript/ESM projects, prefer named imports for specific utilities. The README's `require` example is generally for the entire CommonJS module.
capitalize
wrong:
```
import capitalize from 'easy-soft-utility/capitalize';
```
correct:
```
import { capitalize } from 'easy-soft-utility';
```
Most modern utility libraries use named exports from the main package for tree-shaking rather than sub-path imports for individual functions.
delay
wrong:
```
const { delay } = require('easy-soft-utility');
```
correct:
```
import { delay } from 'easy-soft-utility';
```
While CommonJS `require` can destructure, ESM named imports (`import { delay } from '...'`) are the idiomatic approach in TypeScript environments.

Quickstart

Demonstrates basic type checking, string manipulation, and an asynchronous delay using inferred utility functions.

import { isString, capitalize, delay } from 'easy-soft-utility';

function processInput(input: unknown): string {
  if (isString(input)) {
    return capitalize(input.trim());
  } else {
    return `Invalid input type: ${typeof input}`;
  }
}

async function simulateOperation(value: string) {
  console.log(`Starting operation for: ${processInput(value)}`);
  await delay(2000); // Simulate an async delay
  console.log('Operation completed.');
}

console.log(processInput('  hello world  '));
console.log(processInput(123));

simulateOperation('async task example');
