Unlock the Power of Clear Module

The clear-module is a powerful tool designed to help developers efficiently manage their modules. With a variety of APIs, it offers the flexibility to clear modules from the node.js require cache, ensuring a smooth development experience. Let’s dive into dozens of useful API explanations and examples to make the most out of clear-module.

API Explanations and Examples

Basic Usage

To start using clear-module, you first need to install it:

  npm install clear-module

Clearing a Single Module

You can clear a single module from the require cache with the following code:

  const clearModule = require('clear-module');
  clearModule('./path/to/module');

Clearing Multiple Modules

Clearing multiple modules is also straightforward. Simply provide an array of module paths:

  const clearModule = require('clear-module');
  clearModule(['./path/to/module1', './path/to/module2']);

Clearing Module and Dependencies

If you need to clear a module along with its dependencies, you can use the following code:

  const clearModule = require('clear-module');
  clearModule('./path/to/module', { recursive: true });

Ignoring Specific Modules

You can ignore specific modules while clearing others:

  const clearModule = require('clear-module');
  clearModule('./path/to/module', { ignore: ['lodash'] });

Event Handling

Handle events before and after clearing modules:

  const clearModule = require('clear-module');
  
  clearModule.on('beforeClear', (modulePath) => {
    console.log(`Before clearing: ${modulePath}`);
  });
  
  clearModule.on('afterClear', (modulePath) => {
    console.log(`After clearing: ${modulePath}`);
  });
  
  clearModule('./path/to/module');

Application Example

Here’s a full example application to demonstrate how to use clear-module in a real-world scenario:

  const clearModule = require('clear-module');
  const express = require('express');
  const app = express();

  app.use((req, res, next) => {
    clearModule.all();
    next();
  });

  app.get('/', (req, res) => {
    const myModule = require('./myModule');
    res.send(myModule.getContent());
  });

  app.listen(3000, () => {
    console.log('Server running on http://localhost:3000');
  });

By using clear-module in an Express.js application, you can ensure that your modules are always fresh and updated without needing to restart the server, enhancing your development workflow.

With these powerful APIs and features, clear-module proves to be an indispensable tool for developers working with node.js. Start using clear-module today to optimize your module management process.
