|
||
|
|
|
||
|
|
yet another unzip library for node. For zipping, see
|
||
|
|
[yazl](https://github.com/thejoshwolfe/yazl).
|
||
|
|
|
||
|
|
Design principles:
|
||
|
|
|
||
|
|
* Follow the spec.
|
||
|
|
Don't scan for local file headers.
|
||
|
|
Read the central directory for file metadata.
|
||
|
|
(see [No Streaming Unzip API](#no-streaming-unzip-api)).
|
||
|
|
* Don't block the JavaScript thread.
|
||
|
|
Use and provide async APIs.
|
||
|
|
* Keep memory usage under control.
|
||
|
|
Don't attempt to buffer entire files in RAM at once.
|
||
|
|
* Never crash (if used properly).
|
||
|
|
Don't let malformed zip files bring down client applications who are trying to catch errors.
|
||
|
|
* Catch unsafe filenames entries.
|
||
|
|
A zip file entry throws an error if its file name starts with `"/"` or `/[A-Za-z]:\//`
|
||
|
|
or if it contains `".."` path segments or `"\\"` (per the spec).
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var yauzl = require("yauzl");
|
||
|
|
var fs = require("fs");
|
||
|
|
var path = require("path");
|
||
|
|
var mkdirp = require("mkdirp"); // or similar
|
||
|
|
|
||
|
|
yauzl.open("path/to/file.zip", {lazyEntries: true}, function(err, zipfile) {
|
||
|
|
if (err) throw err;
|
||
|
|
zipfile.readEntry();
|
||
|
|
zipfile.on("entry", function(entry) {
|
||
|
|
if (/\/$/.test(entry.fileName)) {
|
||
|
|
// directory file names end with '/'
|
||
|
|
mkdirp(entry.fileName, function(err) {
|
||
|
|
if (err) throw err;
|
||
|
|
zipfile.readEntry();
|
||
|
|
});
|
||
|
|
} else {
|
||
|
|
// file entry
|
||
|
|
zipfile.openReadStream(entry, function(err, readStream) {
|
||
|
|
if (err) throw err;
|
||
|
|
// ensure parent directory exists
|
||
|
|
mkdirp(path.dirname(entry.fileName), function(err) {
|
||
|
|
if (err) throw err;
|
||
|
|
readStream.pipe(fs.createWriteStream(entry.fileName));
|
||
|
|
readStream.on("end", function() {
|
||
|
|
zipfile.readEntry();
|
||
|
|
});
|
||
|
|
});
|
||
|
|
});
|
||
|
|
}
|
||
|
|
});
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
## API
|
||
|
|
|
||
|
|
The default for every optional `callback` parameter is:
|
||
|
|
|
||
|
|
```js
|
||
|
|
function defaultCallback(err) {
|
||
|
|
if (err) throw err;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### open(path, [options], [callback])
|
||
|
|
|
||
|
|
Calls `fs.open(path, "r")` and gives the `fd`, `options`, and `callback` to `fromFd()` below.
|
||
|
|
|
||
|
|
`options` may be omitted or `null`. The defaults are `{autoClose: true, lazyEntries: false}`.
|
||
|
|
|
||
|
|
`autoClose` is effectively equivalent to:
|
||
|
|
|
||
|
|
```js
|
||
|
|
zipfile.once("end", function() {
|
||
|
|
zipfile.close();
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
`lazyEntries` indicates that entries should be read only when `readEntry()` is called.
|
||
|
|
If `lazyEntries` is `false`, `entry` events will be emitted as fast as possible to allow `pipe()`ing
|
||
|
|
file data from all entries in parallel.
|
||
|
|
This is not recommended, as it can lead to out of control memory usage for zip files with many entries.
|
||
|
|
See [issue #22](https://github.com/thejoshwolfe/yauzl/issues/22).
|
||
|
|
If `lazyEntries` is `true`, an `entry` or `end` event will be emitted in response to each call to `readEntry()`.
|
||
|
|
This allows processing of one entry at a time, and will keep memory usage under control for zip files with many entries.
|
||
|
|
|
||
|
|
### fromFd(fd, [options], [callback])
|
||
|
|
|
||
|
|
Reads from the fd, which is presumed to be an open .zip file.
|
||
|
|
Note that random access is required by the zip file specification,
|
||
|
|
so the fd cannot be an open socket or any other fd that does not support random access.
|
||
|
|
|
||
|
|
The `callback` is given the arguments `(err, zipfile)`.
|
||
|
|
An `err` is provided if the End of Central Directory Record Signature cannot be found in the file,
|
||
|
|
which indicates that the fd is not a zip file.
|
||
|
|
`zipfile` is an instance of `ZipFile`.
|
||
|
|
|
||
|
|
`options` may be omitted or `null`. The defaults are `{autoClose: false, lazyEntries: false}`.
|
||
|
|
See `open()` for the meaning of the options.
|
||
|
|
|
||
|
|
### fromBuffer(buffer, [options], [callback])
|
||
|
|
|
||
|
|
Like `fromFd()`, but reads from a RAM buffer instead of an open file.
|
||
|
|
`buffer` is a `Buffer`.
|
||
|
|
`callback` is effectively passed directly to `fromFd()`.
|
||
|
|
|
||
|
|
If a `ZipFile` is acquired from this method,
|
||
|
|
it will never emit the `close` event,
|
||
|
|
and calling `close()` is not necessary.
|
||
|
|
|
||
|
|
`options` may be omitted or `null`. The defaults are `{lazyEntries: false}`.
|
||
|
|
See `open()` for the meaning of the options.
|
||
|
|
The `autoClose` option is ignored for this method.
|
||
|
|
|
||
|
|
### fromRandomAccessReader(reader, totalSize, [options], [callback])
|
||
|
|
|
||
|
|
This method of creating a zip file allows clients to implement their own back-end file system.
|
||
|
|
For example, a client might translate read calls into network requests.
|
||
|
|
|
||
|
|
The `reader` parameter must be of a type that is a subclass of
|
||
|
|
[RandomAccessReader](#class-randomaccessreader) that implements the required methods.
|
||
|
|
The `totalSize` is a Number and indicates the total file size of the zip file.
|
||
|
|
|
||
|
|
`options` may be omitted or `null`. The defaults are `{autoClose: true, lazyEntries: false}`.
|
||
|
|
See `open()` for the meaning of the options.
|
||
|
|
|
||
|
|
### dosDateTimeToDate(date, time)
|
||
|
|
|
||
|
|
Converts MS-DOS `date` and `time` data into a JavaScript `Date` object.
|
||
|
|
Each parameter is a `Number` treated as an unsigned 16-bit integer.
|
||
|
|
Note that this format does not support timezones,
|
||
|
|
so the returned object will use the local timezone.
|
||
|
|
|
||
|
|
### Class: ZipFile
|
||
|
|
|
||
|
|
The constructor for the class is not part of the public API.
|
||
|
|
Use `open()`, `fromFd()`, `fromBuffer()`, or `fromRandomAccessReader()` instead.
|
||
|
|
|
||
|
|
#### Event: "entry"
|
||
|
|
|
||
|
|
Callback gets `(entry)`, which is an `Entry`.
|
||
|
|
See `open()` and `readEntry()` for when this event is emitted.
|
||
|
|
|
||
|
|
#### Event: "end"
|
||
|
|
|
||
|
|
Emitted after the last `entry` event has been emitted.
|
||
|
|
See `open()` and `readEntry()` for more info on when this event is emitted.
|
||
|
|
|
||
|
|
#### Event: "close"
|
||
|
|
|
||
|
|
Emitted after the fd is actually closed.
|
||
|
|
This is after calling `close()` (or after the `end` event when `autoClose` is `true`),
|
||
|
|
and after all stream pipelines created from `openReadStream()` have finished reading data from the fd.
|
||
|
|
|
||
|
|
If this `ZipFile` was acquired from `fromRandomAccessReader()`,
|
||
|
|
the "fd" in the previous paragraph refers to the `RandomAccessReader` implemented by the client.
|
||
|
|
|
||
|
|
If this `ZipFile` was acquired from `fromBuffer()`, this event is never emitted.
|
||
|
|
|
||
|
|
#### Event: "error"
|
||
|
|
|
||
|
|
Emitted in the case of errors with reading the zip file.
|
||
|
|
(Note that other errors can be emitted from the streams created from `openReadStream()` as well.)
|
||
|
|
After this event has been emitted, no further `entry`, `end`, or `error` events will be emitted,
|
||
|
|
but the `close` event may still be emitted.
|
||
|
|
|
||
|
|
#### readEntry()
|
||
|
|
|
||
|
|
Causes this `ZipFile` to emit an `entry` or `end` event (or an `error` event).
|
||
|
|
This method must only be called when this `ZipFile` was created with the `lazyEntries` option set to `true` (see `open()`).
|
||
|
|
When this `ZipFile` was created with the `lazyEntries` option set to `true`,
|
||
|
|
`entry` and `end` events are only ever emitted in response to this method call.
|
||
|
|
|
||
|
|
The event that is emitted in response to this method will not be emitted until after this method has returned,
|
||
|
|
so it is safe to call this method before attaching event listeners.
|
||
|
|
|
||
|
|
After calling this method, calling this method again before the response event has been emitted will cause undefined behavior.
|
||
|
|
Calling this method after the `end` event has been emitted will cause undefined behavior.
|
||
|
|
Calling this method after calling `close()` will cause undefined behavior.
|
||
|
|
|
||
|
|
#### openReadStream(entry, callback)
|
||
|
|
|
||
|
|
`entry` must be an `Entry` object from this `ZipFile`.
|
||
|
|
`callback` gets `(err, readStream)`, where `readStream` is a `Readable Stream`.
|
||
|
|
If the entry is compressed (with a supported compression method),
|
||
|
|
the read stream provides the decompressed data.
|
||
|
|
If this zipfile is already closed (see `close()`), the `callback` will receive an `err`.
|
||
|
|
|
||
|
|
It's possible for the `readStream` it to emit errors for several reasons.
|
||
|
|
For example, if zlib cannot decompress the data, the zlib error will be emitted from the `readStream`.
|
||
|
|
Two more error cases are if the decompressed data has too many or too few actual bytes
|
||
|
|
compared to the reported byte count from the entry's `uncompressedSize` field.
|
||
|
|
yauzl notices this false information and emits an error from the `readStream`
|
||
|
|
after some number of bytes have already been piped through the stream.
|
||
|
|
|
||
|
|
Because of this check, clients can always trust the `uncompressedSize` field in `Entry` objects.
|
||
|
|
Guarding against [zip bomb](http://en.wikipedia.org/wiki/Zip_bomb) attacks can be accomplished by
|
||
|
|
doing some heuristic checks on the size metadata and then watching out for the above errors.
|
||
|
|
Such heuristics are outside the scope of this library,
|
||
|
|
but enforcing the `uncompressedSize` is implemented here as a security feature.
|
||
|
|
|
||
|
|
It is possible to destroy the `readStream` before it has piped all of its data.
|
||
|
|
To do this, call `readStream.destroy()`.
|
||
|
|
You must `unpipe()` the `readStream` from any destination before calling `readStream.destroy()`.
|
||
|
|
If this zipfile was created using `fromRandomAccessReader()`, the `RandomAccessReader` implementation
|
||
|
|
must provide readable streams that implement a `.destroy()` method (see `randomAccessReader._readStreamForRange()`)
|
||
|
|
in order for calls to `readStream.destroy()` to work in this context.
|
||
|
|
|
||
|
|
#### close()
|
||
|
|
|
||
|
|
Causes all future calls to `openReadStream()` to fail,
|
||
|
|
and closes the fd after all streams created by `openReadStream()` have emitted their `end` events.
|
||
|
|
|
||
|
|
If the `autoClose` option is set to `true` (see `open()`),
|
||
|
|
this function will be called automatically effectively in response to this object's `end` event.
|
||
|
|
|
||
|
|
If the `lazyEntries` option is set to `false` (see `open()`) and this object's `end` event has not been emitted yet,
|
||
|
|
this function causes undefined behavior.
|
||
|
|
If the `lazyEntries` option is set to `true`,
|
||
|
|
you can call this function instead of calling `readEntry()` to abort reading the entries of a zipfile.
|
||
|
|
|
||
|
|
It is safe to call this function multiple times; after the first call, successive calls have no effect.
|
||
|
|
This includes situations where the `autoClose` option effectively calls this function for you.
|
||
|
|
|
||
|
|
#### isOpen
|
||
|
|
|
||
|
|
`Boolean`. `true` until `close()` is called; then it's `false`.
|
||
|
|
|
||
|
|
#### entryCount
|
||
|
|
|
||
|
|
`Number`. Total number of central directory records.
|
||
|
|
|
||
|
|
#### comment
|
||
|
|
|
||
|
|
`String`. Always decoded with `CP437` per the spec.
|
||
|
|
|
||
|
|
### Class: Entry
|
||
|
|
|
||
|
|
Objects of this class represent Central Directory Records.
|
||
|
|
Refer to the zipfile specification for more details about these fields.
|
||
|
|
|
||
|
|
These fields are of type `Number`:
|
||
|
|
|
||
|
|
* `versionMadeBy`
|
||
|
|
* `versionNeededToExtract`
|
||
|
|
* `generalPurposeBitFlag`
|
||
|
|
* `compressionMethod`
|
||
|
|
* `lastModFileTime` (MS-DOS format, see `getLastModDateTime`)
|
||
|
|
* `lastModFileDate` (MS-DOS format, see `getLastModDateTime`)
|
||
|
|
* `crc32`
|
||
|
|
* `compressedSize`
|
||
|
|
* `uncompressedSize`
|
||
|
|
* `fileNameLength` (bytes)
|
||
|
|
* `extraFieldLength` (bytes)
|
||
|
|
* `fileCommentLength` (bytes)
|
||
|
|
* `internalFileAttributes`
|
||
|
|
* `externalFileAttributes`
|
||
|
|
* `relativeOffsetOfLocalHeader`
|
||
|
|
|
||
|
|
#### fileName
|
||
|
|
|
||
|
|
`String`.
|
||
|
|
Following the spec, the bytes for the file name are decoded with
|
||
|
|
`UTF-8` if `generalPurposeBitFlag & 0x800`, otherwise with `CP437`.
|
||
|
|
|
||
|
|
If `fileName` would contain unsafe characters, such as an absolute path or
|
||
|
|
a relative directory, yauzl emits an error instead of an entry.
|
||
|
|
|
||
|
|
#### extraFields
|
||
|
|
|
||
|
|
`Array` with each entry in the form `{id: id, data: data}`,
|
||
|
|
where `id` is a `Number` and `data` is a `Buffer`.
|
||
|
|
This library looks for and reads the ZIP64 Extended Information Extra Field (0x0001)
|
||
|
|
in order to support ZIP64 format zip files.
|
||
|
|
None of the other fields are considered significant by this library.
|
||
|
|
|
||
|
|
#### comment
|
||
|
|
|
||
|
|
`String` decoded with the same charset as used for `fileName`.
|
||
|
|
|
||
|
|
#### getLastModDate()
|
||
|
|
|
||
|
|
Effectively implemented as:
|
||
|
|
|
||
|
|
```js
|
||
|
|
return dosDateTimeToDate(this.lastModFileDate, this.lastModFileTime);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Class: RandomAccessReader
|
||
|
|
|
||
|
|
This class is meant to be subclassed by clients and instantiated for the `fromRandomAccessReader()` function.
|
||
|
|
|
||
|
|
An example implementation can be found in `test/test.js`.
|
||
|
|
|
||
|
|
#### randomAccessReader._readStreamForRange(start, end)
|
||
|
|
|
||
|
|
Subclasses *must* implement this method.
|
||
|
|
|
||
|
|
`start` and `end` are Numbers and indicate byte offsets from the start of the file.
|
||
|
|
`end` is exclusive, so `_readStreamForRange(0x1000, 0x2000)` would indicate to read `0x1000` bytes.
|
||
|
|
`end - start` will always be at least `1`.
|
||
|
|
|
||
|
|
This method should return a readable stream which will be `pipe()`ed into another stream.
|
||
|
|
It is expected that the readable stream will provide data in several chunks if necessary.
|
||
|
|
If the readable stream provides too many or too few bytes, an error will be emitted.
|
||
|
|
Any errors emitted on the readable stream will be handled and re-emitted on the client-visible stream
|
||
|
|
(returned from `zipfile.openReadStream()`) or provided as the `err` argument to the appropriate callback
|
||
|
|
(for example, for `fromRandomAccessReader()`).
|
||
|
|
|
||
|
|
The returned stream *must* implement a method `.destroy()`
|
||
|
|
if you call `readStream.destroy()` on streams you get from `openReadStream()`.
|
||
|
|
If you never call `readStream.destroy()`, then streams returned from this method do not need to implement a method `.destroy()`.
|
||
|
|
`.destroy()` should abort any streaming that is in progress and clean up any associated resources.
|
||
|
|
`.destroy()` will only be called after the stream has been `unpipe()`d from its destination.
|
||
|
|
|
||
|
|
Note that the stream returned from this method might not be the same object that is provided by `openReadStream()`.
|
||
|
|
The stream returned from this method might be `pipe()`d through one or more filter streams (for example, a zlib inflate stream).
|
||
|
|
|
||
|
|
#### randomAccessReader.read(buffer, offset, length, position, callback)
|
||
|
|
|
||
|
|
Subclasses may implement this method.
|
||
|
|
The default implementation uses `createReadStream()` to fill the `buffer`.
|
||
|
|
|
||
|
|
This method should behave like `fs.read()`.
|
||
|
|
|
||
|
|
#### randomAccessReader.close(callback)
|
||
|
|
|
||
|
|
Subclasses may implement this method.
|
||
|
|
The default implementation is effectively `setImmediate(callback);`.
|
||
|
|
|
||
|
|
`callback` takes parameters `(err)`.
|
||
|
|
|
||
|
|
This method is called once the all streams returned from `_readStreamForRange()` have ended,
|
||
|
|
and no more `_readStreamForRange()` or `read()` requests will be issued to this object.
|
||
|
|
|
||
|
|
## How to Avoid Crashing
|
||
|
|
|
||
|
|
When a malformed zipfile is encountered, the default behavior is to crash (throw an exception).
|
||
|
|
If you want to handle errors more gracefully than this,
|
||
|
|
be sure to do the following:
|
||
|
|
|
||
|
|
* Provide `callback` parameters where they are allowed, and check the `err` parameter.
|
||
|
|
* Attach a listener for the `error` event on any `ZipFile` object you get from `open()`, `fromFd()`, `fromBuffer()`, or `fromRandomAccessReader()`.
|
||
|
|
* Attach a listener for the `error` event on any stream you get from `openReadStream()`.
|
||
|
|
|
||
|
|
## Limitations
|
||
|
|
|
||
|
|
### No Streaming Unzip API
|

|
|
|
||
|
|
Due to the design of the .zip file format, it's impossible to interpret a .zip file from start to finish
|
||
|
|
(such as from a readable stream) without sacrificing correctness.
|
||
|
|
The Central Directory, which is the authority on the contents of the .zip file, is at the end of a .zip file, not the beginning.
|
||
|
|
A streaming API would need to either buffer the entire .zip file to get to the Central Directory before interpreting anything
|
||
|
|
(defeating the purpose of a streaming interface), or rely on the Local File Headers which are interspersed through the .zip file.
|
||
|
|
However, the Local File Headers are explicitly denounced in the spec as being unreliable copies of the Central Directory,
|
||
|
|
so trusting them would be a violation of the spec.
|
||
|
|
|
||
|
|
Any library that offers a streaming unzip API must make one of the above two compromises,
|
||
|
|
which makes the library either dishonest or nonconformant (usually the latter).
|
||
|
|
This library insists on correctness and adherence to the spec, and so does not offer a streaming API.
|
||
|
|
|
||
|
|
### Limitted ZIP64 Support
|
||
|
|
|
||
|
|
For ZIP64, only zip files smaller than `8PiB` are supported,
|
||
|
|
not the full `16EiB` range that a 64-bit integer should be able to index.
|
||
|
|
This is due to the JavaScript Number type being an IEEE 754 double precision float.
|
||
|
|
|
||
|
|
The Node.js `fs` module probably has this same limitation.
|
||
|
|
|
||
|
|
### ZIP64 Extensible Data Sector Is Ignored
|
||
|
|
|
||
|
|
The spec does not allow zip file creators to put arbitrary data here,
|
||
|
|
but rather reserves its use for PKWARE and mentions something about Z390.
|
||
|
|
This doesn't seem useful to expose in this library, so it is ignored.
|
||
|
|
|
||
|
|
### No Multi-Disk Archive Support
|
||
|
|
|
||
|
|
This library does not support multi-disk zip files.
|
||
|
|
The multi-disk fields in the zipfile spec were intended for a zip file to span multiple floppy disks,
|
||
|
|
which probably never happens now.
|
||
|
|
If the "number of this disk" field in the End of Central Directory Record is not `0`,
|
||
|
|
the `open()`, `fromFd()`, `fromBuffer()`, or `fromRandomAccessReader()` `callback` will receive an `err`.
|
||
|
|
By extension the following zip file fields are ignored by this library and not provided to clients:
|
||
|
|
|
||
|
|
* Disk where central directory starts
|
||
|
|
* Number of central directory records on this disk
|
||
|
|
* Disk number where file starts
|
||
|
|
|
||
|
|
### No Encryption Support
|
||
|
|
|
||
|
|
Currently, the presence of encryption is not even checked,
|
||
|
|
and encrypted zip files will cause undefined behavior.
|
||
|
|
|
||
|
|
### Local File Headers Are Ignored
|
||
|
|
|
||
|
|
Many unzip libraries mistakenly read the Local File Header data in zip files.
|
||
|
|
This data is officially defined to be redundant with the Central Directory information,
|
||
|
|
and is not to be trusted.
|
||
|
|
Aside from checking the signature, yauzl ignores the content of the Local File Header.
|
||
|
|
|
||
|
|
### No CRC-32 Checking
|
||
|
|
|
||
|
|
This library provides the `crc32` field of `Entry` objects read from the Central Directory.
|
||
|
|
However, this field is not used for anything in this library.
|
||
|
|
|
||
|
|
### versionNeededToExtract Is Ignored
|
||
|
|
|
||
|
|
The field `versionNeededToExtract` is ignored,
|
||
|
|
because this library doesn't support the complete zip file spec at any version,
|
||
|
|
|
||
|
|
### No Support For Obscure Compression Methods
|
||
|
|
|
||
|
|
Regarding the `compressionMethod` field of `Entry` objects,
|
||
|
|
only method `0` (stored with no compression)
|
||
|
|
and method `8` (deflated) are supported.
|
||
|
|
Any of the other 15 official methods will cause the `openReadStream()` `callback` to receive an `err`.
|
||
|
|
|
||
|
|
### Data Descriptors Are Ignored
|
||
|
|
|
||
|
|
There may or may not be Data Descriptor sections in a zip file.
|
||
|
|
This library provides no support for finding or interpreting them.
|
||
|
|
|
||
|
|
### Archive Extra Data Record Is Ignored
|
||
|
|
|
||
|
|
There may or may not be an Archive Extra Data Record section in a zip file.
|
||
|
|
This library provides no support for finding or interpreting it.
|
||
|
|
|
||
|
|
### No Language Encoding Flag Support
|
||
|
|
|
||
|
|
Zip files officially support charset encodings other than CP437 and UTF-8,
|
||
|
|
but the zip file spec does not specify how it works.
|
||
|
|
This library makes no attempt to interpret the Language Encoding Flag.
