pizzip

What is pizzip?

Pizzip is a JavaScript library for creating, reading, and editing zip files in the browser or Node.js. It is particularly useful for handling Office Open XML files, such as .docx, .xlsx, and .pptx, which are essentially zip files containing XML documents.

What are pizzip's main functionalities?

Create a new zip file

This feature allows you to create a new zip file and add files to it. In this example, a new zip file is created, and a text file named 'hello.txt' with the content 'Hello, World!' is added to it.

const PizZip = require('pizzip');
const zip = new PizZip();
zip.file('hello.txt', 'Hello, World!');
const content = zip.generate({ type: 'nodebuffer' });

Read a zip file

This feature allows you to read an existing zip file. In this example, a zip file named 'example.zip' is read, and the content of the file 'hello.txt' within the zip is extracted as text.

const PizZip = require('pizzip');
const fs = require('fs');
const data = fs.readFileSync('example.zip');
const zip = new PizZip(data);
const fileContent = zip.file('hello.txt').asText();

Modify a file within a zip

This feature allows you to modify the content of a file within an existing zip file. In this example, the content of 'hello.txt' within 'example.zip' is changed to 'Modified content'.

const PizZip = require('pizzip');
const fs = require('fs');
const data = fs.readFileSync('example.zip');
const zip = new PizZip(data);
zip.file('hello.txt', 'Modified content');
const newContent = zip.generate({ type: 'nodebuffer' });
