# Archiver v1.3.0
|
||||
|
||||
[](https://travis-ci.org/archiverjs/node-archiver) [](https://ci.appveyor.com/project/ctalkington/node-archiver/branch/master)
|
||||
|
||||
a streaming interface for archive generation
|
||||
|
||||
Visit the [API documentation](http://archiverjs.com/docs) for a list of all methods available.
|
||||
|
||||
## Install
|
||||
|
||||
```bash
|
||||
npm install archiver --save
|
||||
```
|
||||
|
||||
## Quick Start
|
||||
|
||||
```js
|
||||
// require modules
|
||||
var fs = require('fs');
|
||||
var archiver = require('archiver');
|
||||
|
||||
// create a file to stream archive data to.
|
||||
var output = fs.createWriteStream(__dirname + '/example.zip');
|
||||
var archive = archiver('zip', {
|
||||
store: true // Sets the compression method to STORE.
|
||||
});
|
||||
|
||||
// listen for all archive data to be written
|
||||
output.on('close', function() {
|
||||
console.log(archive.pointer() + ' total bytes');
|
||||
console.log('archiver has been finalized and the output file descriptor has closed.');
|
||||
});
|
||||
|
||||
// good practice to catch this error explicitly
|
||||
archive.on('error', function(err) {
|
||||
throw err;
|
||||
});
|
||||
|
||||
// pipe archive data to the file
|
||||
archive.pipe(output);
|
||||
|
||||
// append a file from stream
|
||||
var file1 = __dirname + '/file1.txt';
|
||||
archive.append(fs.createReadStream(file1), { name: 'file1.txt' });
|
||||
|
||||
// append a file from string
|
||||
archive.append('string cheese!', { name: 'file2.txt' });
|
||||
|
||||
// append a file from buffer
|
||||
var buffer3 = new Buffer('buff it!');
|
||||
archive.append(buffer3, { name: 'file3.txt' });
|
||||
|
||||
// append a file
|
||||
archive.file('file1.txt', { name: 'file4.txt' });
|
||||
|
||||
// append files from a directory
|
||||
archive.directory('subdir/');
|
||||
|
||||
// append files from a glob pattern
|
||||
archive.glob('subdir/*.txt');
|
||||
|
||||
// finalize the archive (ie we are done appending files but streams have to finish yet)
|
||||
archive.finalize();
|
||||
```
|
||||
|
||||
## Formats
|
||||
|
||||
Archiver ships with out of the box support for TAR and ZIP archives.
|
||||
|
||||
You can register additional formats with `registerFormat`.
|
||||
|
||||
_Formats will be changing in the next few releases to implement a middleware approach._
