What is @yarnpkg/libzip?

@yarnpkg/libzip is a library that provides functionalities for working with ZIP archives. It is part of the Yarn package manager's ecosystem and allows for creating, reading, and manipulating ZIP files programmatically.

What are @yarnpkg/libzip's main functionalities?

Creating a ZIP Archive

This code demonstrates how to create a ZIP archive and add a file to it using @yarnpkg/libzip. The `makeInterface` function initializes the libzip interface, and `ZipFS` is used to create and manipulate the ZIP file.

const { makeInterface } = require('@yarnpkg/libzip');
const { ZipFS } = require('@yarnpkg/fslib');

(async () => {
  const libzip = await makeInterface();
  const zipFs = new ZipFS(null, { libzip });

  zipFs.writeFileSync('/file.txt', 'Hello, world!');
  zipFs.saveAndClose();
})();

Reading a ZIP Archive

This code demonstrates how to read a ZIP archive and extract a file's content using @yarnpkg/libzip. The ZIP file is read from the filesystem, and `ZipFS` is used to access and read the file within the archive.

const { makeInterface } = require('@yarnpkg/libzip');
const { ZipFS } = require('@yarnpkg/fslib');
const fs = require('fs');

(async () => {
  const libzip = await makeInterface();
  const zipData = fs.readFileSync('archive.zip');
  const zipFs = new ZipFS(zipData, { libzip });

  const content = zipFs.readFileSync('/file.txt', 'utf8');
  console.log(content); // Outputs: Hello, world!
})();

Listing Files in a ZIP Archive

This code demonstrates how to list all files in a ZIP archive using @yarnpkg/libzip. The ZIP file is read from the filesystem, and `ZipFS` is used to list the files within the archive.

const { makeInterface } = require('@yarnpkg/libzip');
const { ZipFS } = require('@yarnpkg/fslib');
const fs = require('fs');

(async () => {
  const libzip = await makeInterface();
  const zipData = fs.readFileSync('archive.zip');
  const zipFs = new ZipFS(zipData, { libzip });

  const files = zipFs.readdirSync('/');
  console.log(files); // Outputs: ['file.txt']
})();
