Basic Usage

Let’s cover some of the basic functionalities provided by node7z.

Creating an Archive

To create an archive, use the following API:

  const { add } = require('node-7z');
  const myPromise = add('archive.7z', '*.txt', { recursive: true });

  myPromise.then(() => {
    console.log('Archive created successfully.');
  }).catch(err => {
    console.error('Error creating archive:', err);
  });

Extracting an Archive

To extract an archive, use the following code:

  const { extract } = require('node-7z');
  const myPromise = extract('archive.7z', 'output-directory/');

  myPromise.then(() => {
    console.log('Extraction completed.');
  }).catch(err => {
    console.error('Error extracting archive:', err);
  });

Listing Archive Contents

You can list the contents of an archive using:

  const { list } = require('node-7z');
  const myPromise = list('archive.7z');

  myPromise.then(list => {
    console.log('List of files:', list);
  }).catch(err => {
    console.error('Error listing files:', err);
  });

An App Example Using node7z

Let’s build a simple Node.js app that creates, extracts, and lists the contents of an archive file.

  const express = require('express');
  const { add, extract, list } = require('node-7z');
  const app = express();
  
  app.get('/create', (req, res) => {
    add('archive.7z', '*.txt').then(() => {
      res.send('Archive created successfully.');
    }).catch(err => {
      res.status(500).send('Error creating archive.');
    });
  });

  app.get('/extract', (req, res) => {
    extract('archive.7z', 'output-directory/').then(() => {
      res.send('Extraction completed.');
    }).catch(err => {
      res.status(500).send('Error extracting archive.');
    });
  });

  app.get('/list', (req, res) => {
    list('archive.7z').then(list => {
      res.json(list);
    }).catch(err => {
      res.status(500).send('Error listing files.');
    });
  });

  app.listen(3000, () => {
    console.log('Server is running on port 3000');
  });

Conclusion

node7z provides a robust and simple way to manage archives within your Node.js applications. By utilizing the provided APIs, you can easily create, extract, and list contents of archive files.
