Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
The tar-fs npm package is a Node.js module that allows you to interact with tarball (.tar) files. It provides functionality to pack and extract tarball files using file system streams. It is a high-level module that makes it easy to create and extract tar files in a Node.js environment.
Packing files into a tarball
This feature allows you to pack a directory into a tarball. The code sample demonstrates how to pack the contents of '/source/directory' into a tarball named 'archive.tar' located at '/destination/'.
const tar = require('tar-fs');
const fs = require('fs');
let pack = tar.pack('/source/directory')
.pipe(fs.createWriteStream('/destination/archive.tar'));
Extracting files from a tarball
This feature allows you to extract the contents of a tarball into a directory. The code sample demonstrates how to extract the contents of 'archive.tar' from '/source/' into the '/destination/directory'.
const tar = require('tar-fs');
const fs = require('fs');
fs.createReadStream('/source/archive.tar')
.pipe(tar.extract('/destination/directory'));
The 'tar' package is another Node.js module for manipulating tar files. It provides similar functionality to tar-fs, such as packing and extracting tarball files. However, it also includes support for additional features like gzip compression and incremental backups.
Archiver is a streaming interface for archive generation, supporting ZIP and TAR formats. It offers more format options than tar-fs and includes features like appending to existing archives and setting global archive headers.

npm install tar-fs
tar-fs allows you to pack directories into tarballs and extract tarballs into directories.
var tar = require('tar-fs');
var fs = require('fs');
// packing a directory
tar.pack('./my-directory').pipe(fs.createWriteStream('my-tarball.tar'));
// extracting a directory
fs.createReadStream('my-other-tarball.tar').pipe(tar.extract('./my-other-directory'));
To ignore various files when packing or extracting add a ignore function to the options
var pack = tar.pack('./my-directory', {
ignore: function(name) {
return path.extname(name) === '.bin'; // ignore .bin files when packing
}
});
var extract = tar.extract('./my-other-directory', {
ignore: function(name) {
return path.extname(name) === '.bin'; // ignore .bin files inside the tarball when extracing
}
});
Set options.readable
and options.writable
to ensure that files extracted are readable and/or writable
var extract = tar.extract('./my-directory', {
readable: true,
writable: true
});
This is useful when the tarball was created on windows (which can result in dirs not being readable)
Copying a directory with permissions and mtime intact is as simple as
tar.pack('source-directory').pipe(tar.extract('dest-directory'));
Packing and extracting a 6.1 GB with 2496 directories and 2398 files yields the following results on my Macbook Air. See the benchmark here
