# @electron/asar - Electron Archive
|
||||
|
||||
[](https://github.com/electron/asar/actions/workflows/test.yml)
|
||||
[](https://npmjs.org/package/@electron/asar)
|
||||
|
||||
Asar is a simple extensive archive format, it works like `tar` that concatenates
|
||||
all files together without compression, while having random access support.
|
||||
|
||||
## Features
|
||||
|
||||
* Support random access
|
||||
* Use JSON to store files' information
|
||||
* Very easy to write a parser
|
||||
|
||||
## Command line utility
|
||||
|
||||
### Install
|
||||
|
||||
This module requires Node 10 or later.
|
||||
|
||||
```bash
|
||||
$ npm install --engine-strict @electron/asar
|
||||
```
|
||||
|
||||
### Usage
|
||||
|
||||
```bash
|
||||
$ asar --help
|
||||
|
||||
Usage: asar [options] [command]
|
||||
|
||||
Commands:
|
||||
|
||||
pack|p <dir> <output>
|
||||
create asar archive
|
||||
|
||||
list|l <archive>
|
||||
list files of asar archive
|
||||
|
||||
extract-file|ef <archive> <filename>
|
||||
extract one file from archive
|
||||
|
||||
extract|e <archive> <dest>
|
||||
extract archive
|
||||
|
||||
|
||||
Options:
|
||||
|
||||
-h, --help output usage information
|
||||
-V, --version output the version number
|
||||
|
||||
```
|
||||
|
||||
#### Excluding multiple resources from being packed
|
||||
|
||||
Given:
|
||||
```
|
||||
app
|
||||
(a) ├── x1
|
||||
(b) ├── x2
|
||||
(c) ├── y3
|
||||
(d) │ ├── x1
|
||||
(e) │ └── z1
|
||||
(f) │ └── x2
|
||||
(g) └── z4
|
||||
(h) └── w1
|
||||
```
|
||||
|
||||
Exclude: a, b
|
||||
```bash
|
||||
$ asar pack app app.asar --unpack-dir "{x1,x2}"
|
||||
```
|
||||
|
||||
Exclude: a, b, d, f
|
||||
```bash
|
||||
$ asar pack app app.asar --unpack-dir "**/{x1,x2}"
|
||||
```
|
||||
|
||||
Exclude: a, b, d, f, h
|
||||
```bash
|
||||
$ asar pack app app.asar --unpack-dir "{**/x1,**/x2,z4/w1}"
|
||||
```
|
||||
|
||||
## Using programmatically
|
||||
|
||||
### Example
|
||||
|
||||
```javascript
|
||||
const asar = require('@electron/asar');
|
||||
|
||||
const src = 'some/path/';
|
||||
const dest = 'name.asar';
|
||||
|
||||
await asar.createPackage(src, dest);
|
||||
console.log('done.');
|
||||
```
|
||||
|
||||
Please note that there is currently **no** error handling provided!
|
||||
|
||||
### Transform
|
||||
You can pass in a `transform` option, that is a function, which either returns
|
||||
nothing, or a `stream.Transform`. The latter will be used on files that will be
|
||||
in the `.asar` file to transform them (e.g. compress).
|
||||
|
||||
```javascript
|
||||
const asar = require('@electron/asar');
|
||||
|
||||
const src = 'some/path/';
|
||||
const dest = 'name.asar';
|
||||
|
||||
function transform (filename) {
|
||||
return new CustomTransformStream()
|
||||
}
|
||||
|
||||
await asar.createPackageWithOptions(src, dest, { transform: transform });
|
||||
console.log('done.');
|
||||
```
|
||||
|
||||
## Format
|
||||
|
||||
Asar uses [Pickle][pickle] to safely serialize binary value to file.
|
||||
|
||||
The format of asar is very flat:
|
||||
|
||||
```
|
||||
| UInt32: header_size | String: header | Bytes: file1 | ... | Bytes: file42 |
|
||||
```
|
||||
|
||||
The `header_size` and `header` are serialized with [Pickle][pickle] class, and
|
||||
`header_size`'s [Pickle][pickle] object is 8 bytes.
|
||||
|
||||
The `header` is a JSON string, and the `header_size` is the size of `header`'s
|
||||
`Pickle` object.
|
||||
|
||||
Structure of `header` is something like this:
|
||||
|
||||
```json
|
||||
{
|
||||
"files": {
|
||||
"tmp": {
|
||||
"files": {}
|
||||
},
|
||||
"usr" : {
|
||||
"files": {
|
||||
"bin": {
|
||||
"files": {
|
||||
"ls": {
|
||||
"offset": "0",
|
||||
"size": 100,
|
||||
"executable": true,
|
||||
"integrity": {
|
||||
"algorithm": "SHA256",
|
||||
"hash": "...",
|
||||
"blockSize": 1024,
|
||||
"blocks": ["...", "..."]
|
||||
}
|
||||
},
|
||||
"cd": {
|
||||
"offset": "100",
|
||||
"size": 100,
|
||||
"executable": true,
|
||||
"integrity": {
|
||||
"algorithm": "SHA256",
|
||||
"hash": "...",
|
||||
"blockSize": 1024,
|
||||
"blocks": ["...", "..."]
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
},
|
||||
"etc": {
|
||||
"files": {
|
||||
"hosts": {
|
||||
"offset": "200",
|
||||
"size": 32,
|
||||
"integrity": {
|
||||
"algorithm": "SHA256",
|
||||
"hash": "...",
|
||||
"blockSize": 1024,
|
||||
"blocks": ["...", "..."]
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
`offset` and `size` records the information to read the file from archive, the
|
||||
`offset` starts from 0 so you have to manually add the size of `header_size` and
|
||||
`header` to the `offset` to get the real offset of the file.
|
||||
|
||||
`offset` is a UINT64 number represented in string, because there is no way to
|
||||
precisely represent UINT64 in JavaScript `Number`. `size` is a JavaScript
|
||||
`Number` that is no larger than `Number.MAX_SAFE_INTEGER`, which has a value of
|
||||
`9007199254740991` and is about 8PB in size. We didn't store `size` in UINT64
|
||||
because file size in Node.js is represented as `Number` and it is not safe to
|
||||
convert `Number` to UINT64.
|
||||
|
||||
`integrity` is an object consisting of a few keys:
|
||||
* A hashing `algorithm`, currently only `SHA256` is supported.
|
||||
* A hex encoded `hash` value representing the hash of the entire file.
|
||||
* An array of hex encoded hashes for the `blocks` of the file. i.e. for a blockSize of 4KB this array contains the hash of every block if you split the file into N 4KB blocks.
|
||||
* A integer value `blockSize` representing the size in bytes of each block in the `blocks` hashes above
