import-aliases

A robust and flexible library for setting up absolute path imports with aliases like @app/ in JavaScript and TypeScript projects.

Features

• 🚀 Simple one-line setup for absolute imports
• 🔄 Automatic detection of tsconfig.json or jsconfig.json
• ⚙️ Support for custom configuration paths
• 🧰 Utility to create config files with common alias patterns
• 🎯 Support for custom aliases on top of config-defined ones
• 📝 Detailed logging option for debugging

Installation

npm install import-aliases

Basic Usage In your entry file (e.g., index.js, app.js, or main.ts):

// Register aliases at the very beginning of your app
const { setupAliases } = require('import-aliases');
setupAliases();

// Now you can use absolute imports:
const myModule = require('@app/modules/myModule');

// Or with ES imports:
// import { myComponent } from '@app/components/myComponent';

Configuration Make sure your project has a tsconfig.json or jsconfig.json with paths configured:

{
  "compilerOptions": {
    "baseUrl": "./",
    "paths": {
      "@app/*": ["src/*"],
      "@components/*": ["src/components/*"],
      "@utils/*": ["src/utils/*"]
    }
  }
}

Custom Setup Options Customize the alias setup process:

const { setupAliases } = require('auto-import-helper');

// Advanced setup with options
const registeredAliases = setupAliases({
  // Use a custom config file path
  configPath: './configs/my-tsconfig.json',
  
  // Enable verbose logging
  verbose: true,
  
  // Add custom aliases on top of those defined in the config
  customAliases: {
    '@lib': path.resolve(__dirname, 'lib'),
    '@external': path.resolve(__dirname, 'node_modules/some-module')
  }
});

console.log('Registered aliases:', registeredAliases);

Type Definitions TypeScript type definitions are included and provide full IntelliSense support:

import { setupAliases, createConfigWithAliases } from 'auto-import-helper';

// Full type support for options
setupAliases({
  verbose: true,
  customAliases: {
    '@models': './src/domain/models'
  }
});

Examples Basic Node.js Example

// index.js
const { setupAliases } = require('auto-import-helper');
setupAliases();

// Now use absolute imports
const { User } = require('@app/models/User');

Express.js Example

// app.js
const { setupAliases } = require('auto-import-helper');
setupAliases();

const express = require('express');
const routes = require('@app/routes');
const middlewares = require('@app/middlewares');

const app = express();
// ... app setup

TypeScript Example

// main.ts
import { setupAliases } from 'auto-import-helper';
setupAliases();

import { UserService } from '@app/services/UserService';
import { AppConfig } from '@app/config';

// ... application code
