React HOC Toolkit

A collection of Higher-Order Components (HOCs) designed to enhance and simplify the development of React applications.

Getting Started

To install this package use npm:

npm install react-hoc-toolkit

Usage

withLogger

The withLogger Higher-Order Component (HOC) enhances your React components by logging their props and state changes. This is particularly useful for debugging and understanding the flow of data through your application:

import React from 'react';
import { withLogger } from 'react-hoc-toolkit';

interface MyComponentProps {
    message: string;
}

const MyComponent: React.FC<MyComponentProps> = ({ message }) => {
    return <div>{message}</div>;
};

const MyComponentWithLogger = withLogger(MyComponent);

const App: React.FC = () => {
    return <MyComponentWithLogger message="Hello, World!" />;
};

export default App;

In this example, withLogger is used to wrap MyComponent, which logs the props passed to it. When App renders MyComponentWithLogger with the message "Hello, World!", the props will be logged to the console.

composeHOCs

The composeHOCs function allows you to compose multiple Higher-Order Components (HOCs) into a single HOC. This is useful when you want to apply multiple HOCs to a component in a clean and readable manner.

import React from 'react';
import { composeHOCs, withLogger } from 'react-hoc-toolkit';

interface MyComponentProps {
    message: string;
}

const MyComponent: React.FC<MyComponentProps> = ({ message }) => {
    return <div>{message}</div>;
};

const EnhancedComponent = composeHOCs(withLogger)(MyComponent);

const App: React.FC = () => {
    return <EnhancedComponent message="Hello, World!" />;
};

export default App;

In this example, composeHOCs is used to apply the withLogger HOC to MyComponent. You can pass multiple HOCs to composeHOCs to apply them in sequence.

Local Development

For local development, use Yalc to install this package in your project.

Yalc is a tool for managing local development of npm packages. It allows you to work on this package locally and test it in other projects without publishing to the npm registry.

To use yalc, you need to install it globally on your machine. You can do this using npm:

npm install yalc -g

Installing the Package with Yalc

First, navigate to the project directory where you want to use this package and run:

yalc add react-hoc-toolkit

This will install the package from the local Yalc store. You can now use it in the project as you would with any other npm package.

Updating the Package with Yalc

After publishing changes to this package to the local Yalc store, navigate to the project directory and run:

yalc update react-hoc-toolkit

This will update the installed version of this package in the project.

Available Scripts

In the project directory, you can run:

npm run build

Builds production files in your dist/ folder. It generates CommonJS, ES Modules, as well as TypeScript declaration files.

npm run build:cjs

Builds CommonJS (CJS) modules for the project.

npm run build:esm

Builds ES Modules (ESM) for the project.

npm run build:types

Generates TypeScript declaration files.

npm run clean

Removes the dist/ folder to ensure a clean build.

npm run format

Formats the code using Prettier according to the rules defined in package.json.

npm run test

Runs the test suite for the project using Jest.

npm run test:watch

Runs the test suite in watch mode, re-running tests when files change.

npm run test:coverage

Runs the test suite and generates a coverage report.

npm run yalc:publish

Publishes the package to the local Yalc store for local development.

npm run yalc:push

Publishes updates to the package in the local Yalc store and pushes the changes to linked projects.

Publishing

This repository is configured to publish the package to npm, every time you publish a new release, using GitHub Actions.

Creating and Using an npm Token

To publish the package, you need an npm token:

1. Log in to your npm account.
2. Navigate to Access Tokens in your npm account settings.
3. Generate a new token with the Automation option, especially if you have 2FA enabled.
4. Add the token to your GitHub repository secrets:
   • Go to Settings > Secrets and variables > Actions.
   • Add a new secret named NPM_TOKEN and paste your npm token.
