Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
@electron/asar
Advanced tools
@electron/asar is a Node.js library used to create, manipulate, and extract ASAR (Atom Shell Archive) files. ASAR files are essentially archives used by Electron applications to package their resources. This package provides functionalities to pack files into an ASAR archive, extract files from an ASAR archive, and manipulate the contents of an ASAR archive.
Packing files into an ASAR archive
This feature allows you to pack a directory of files into an ASAR archive. The `createPackage` function takes the source directory and the output file path as arguments and creates the ASAR archive.
const asar = require('@electron/asar');
asar.createPackage('path/to/source', 'path/to/output.asar', function() {
console.log('ASAR archive created successfully!');
});
Extracting files from an ASAR archive
This feature allows you to extract all files from an ASAR archive to a specified directory. The `extractAll` function takes the ASAR archive path and the destination directory as arguments and extracts the contents.
const asar = require('@electron/asar');
asar.extractAll('path/to/archive.asar', 'path/to/destination', function() {
console.log('ASAR archive extracted successfully!');
});
Listing files in an ASAR archive
This feature allows you to list all files contained in an ASAR archive. The `listPackage` function takes the ASAR archive path as an argument and returns an array of file paths contained in the archive.
const asar = require('@electron/asar');
const files = asar.listPackage('path/to/archive.asar');
console.log(files);
The `tar` package is used for reading and writing tar archives. It provides functionalities to create, extract, and list files in tar archives. Unlike ASAR, tar archives are more commonly used and supported across different platforms and tools.
The `zip` package is used for creating and extracting zip archives. It provides functionalities to compress files into a zip archive and extract files from a zip archive. Zip archives are widely used and supported by many applications and operating systems.
The `node-7z` package is a Node.js wrapper for the 7-Zip compression tool. It allows you to create and extract 7z archives, which offer high compression ratios. This package provides similar functionalities to ASAR but uses the 7z format instead.
